Multivessel Versus Culprit-Vessel Percutaneous Coronary Intervention in Cardiogenic Shock

Lemor A, Basir MB, Patel K, et. al. on behalf of the National Cardiogenic Shock Initiative Investigators. J Am Coll Cardiol Intv 2020;13:1171–8

Background

Potential advantages of complete revascularization vs. culprit only PCI in the setting of cardiogenic shock remains controversial in the US. To address this question, data from the National Cardiogenic Shock Initiative (NCSI), a multicenter registry of patients undergoing early MCS (Impella) in the setting of acute myocardial infarction with cardiogenic shock (AMICS). The key features of the suggested protocol include Impella unloading prior to PCI revascularization of the culprit lesion focusing on invasive hemodynamic management. This review encompasses patients with multivessel disease who underwent culprit only or multivessel PCI at the index procedure based on operator decision.

Key Points:

  • The retrospective analysis included 198 patients with multivessel (MV) coronary artery disease (CAD).
  • 126 (64%) had MV PCI; 72 (36%) had culprit only PCI.
  • Baseline characteristics of both groups were similar including age, sex, diabetes, prior PCI or CABG.
  • Patients undergoing MV PCI had a non-significant trend to worse cardiac output and lactate levels up to 12 hours.
  • By 24 hours post PCI, there were similar hemodynamic responses.
  • Survival rates were similar; MV-PCI (69.8%) while culprit PCI 65.3%, p = 0.51.
  • Acute kidney injury was not significantly different – MV-PCI 29.9% vs. culprit only PCI 34.2%; p = 0.64.
  • Similar outcomes for patients undergoing MV- PCI suggests that in selected patients, MC PCI in patients with early unloading is an acceptable approach.

A COVID -19 Perspective

  • Given the need to minimize ICU beds in the event of a COVID – 19 escalation and to minimize patient (and Staff) risk, minimizing hospital days is favorable.
  • Thus, in appropriate AMICS patients, use of an NCSI type protocol with MV-PCI, hospitalization ideally can be reduced with a 70% expected survival.

Paranjpe I, Fuster V, Lala A, et al. Association of Treatment Dose Anticoagulation With In-Hospital Survival Among Hospitalized Patients With COVID-19. J Am Coll Cardiol  2020;May 5:[Epub ahead of print].

Background: In a recent Poll on ACC.org. the questions related to coagulation abnormalities in COVID – 19 patients. As noted, most respondents use anticoagulation in COVID – 19 patients. In order of risk pulmonary emboli was the highest including both in-situ and traditional embolic events.

 

Key Points:

 

  • Baseline coagulation profiles are often abnormal.
  • Thrombotic events appear common
  • Pulmonary emboli appear most common.
  • Prophylactic anticoagulants may reduce the risk of thrombotic events.
  • Paranjpe et al. reported significantly reduced mortality for ventilated patients with COVID-19 on anticoagulants (29.1%) versus 62.7% for those not receiving anticoagulation.
  • Individualized decisions are important to minimize bleeding complications

SCAI Position Statement on Optimal Percutaneous Coronary Interventional Therapy for Complex Coronary Artery Disease

Riley RF, et. al. for the Writing Group. Catheter Cardiovasc Interv. Published online. doi: 10.1002/ccd.28994.

Background:

This document is meant to discuss the approach to the high-risk PCI procedure defined by anatomic and patient features. The document is extensive and thus this commentary seeks to increase the awareness of some of the benefits and procedure related requirements within this topic which warrant consideration in the framework of achieving optimal PCI outcomes.

Key Points:

  • Pre-Procedural Assessment:
    • Coronary Anatomic Complexity – May require advanced techniques
    • Higher-risk clinical features
  • Emphasis on importance on multivessel disease
  • Procedure risk
  • Recognize high risk of surgical turndowns
  • Reduced left ventricular (LV) function
  • Acute Coronary Syndrome – Left Main (LM) and Low LVEF
    • Emphasized the importance of mechanical Support (MCS)
  • Most common is pVAD type of axial pump
  • MCS support shown to increase frequency of complete revascularization
  • Selected cases MCS supports improved LV function
    • Managing the risk of acute kidney injury
    • Miscellaneous
  • Concomitant valve disease
  • Diabetes
  • Treatment of complex coronary artery disease
    • Arterial access
    • Anticoagulation and antiplanet treatment
    • Intracoronary physiologic testing and imaging
    • Special lesion considerations – LM, Bifurcations, Vein Grafts, In-stent Restenosis and Chronic Total Occlusions.
  • The authors conclude: “…this SCAI consensus document provides an initial platform to offer guidance for achieving excellent outcomes for complex PCI and to support future investigations of this growing patient population.

Editorial Comment: This document provides an important roadmap for providing optimal outcomes for PCI in patients with complex coronary artery disease – Its more than “getting out of the lab”! it’s about getting optimal acute and late results. In the current era of COVID, certain of these recommendations become particularly important in attempting to reduce hospital

Reduction of hospitalizations for myocardial infarction in Italy in the COVID-19 era

De Rosa S, Spaccarotella C, Basso C, et. al. European Heart Journal, ehaa409, 

Background:

Early in the 2020 COVID – 19 outbreak, one-week acute myocardial infarction (AMI) nationwide data from 44 Italian hospitals were compared to the equivalent week in 2019.

Key Points:

  • Admissions were reduced for AMI (48.4%, p < 0.001); STEMI (26.5%, p < 0.009) and NSTEMI (65.1%, p < 0.001).
  • Mortality increased for all groups: AMI – 2.8 to 9.7% (p < 0.001); For STEMI – 4.1 to 13.7% (p < 0.001) for NSTEMI; 1.7% to 3.3% (P = NS).
  • Similarly, ICU Heart Failure admissions were reduced by nearly half (46.8%, P = 0.005) in 2020.
  • Major AMI complications (cardiogenic shock, life-threatening arrhythmias, and cardiac rupture/ventricular septal defect (VSD) or severe functional mitral regurgitation) doubled from 7.4% in 2019 to 15.7% in 2020 (p = 0.001).
  • Reductions in STEMI admissions were less significantly less for women (41.2%, P + 0.011) while for men admissions were less, but not significantly (17.8% P + 0.191).
  • The rate of coronary angiography for STEMI patients was similar for both years – 94.5% vs. 94.9%, P = NS).
  • NSTEMI PCI decreased 13.3% (P = 0.023) from 76.7% of patients in 2019 to 66.1% of patients in 2020.
  • 7% of STEMI patients were COVID – 19 positive, with high mortality rate (28.6%), but despite this high rate for the COVID – 19 positive patients, the mortality for non-infected STEMI patients remained significantly higher for 2020 compared to 2019 (P = 0.018).
  • Stated but not numerically documented, the time of first medical contact to PCI was much greater in 2020, emphasizing time to revascularization as well as primary PCI are critical factors.

 

Summary

The authors note that not only were the in-hospital death and complication rates higher among AMI patients but the surviving, untreated AMI patients likely represent a major risk for delayed complex requirements for revascularization and treatment for heart failure.

Key Points:

This summary describes the uses and potential limitations of Extracorporeal membrane oxygenation (ECMO) as well as other mechanical Circulatory (MCS) Devices.

  • Circulatory support in COVID – 19 patients is likely most effective for single organ system disease such as acute respiratory distress syndrome (ARDS) and/or cardiogenic shock.
  • Limitations involve patients with cytokine-mediated myocardial dysfunction plus severe respiratory failure, who despite support have a limited prognosis.
  • VV-ECMO and ARDS. (Extracorporeal Life Support Organization – ELSO).
    • Notes:
  • Contraindications include: older age, mechanical ventilations >7days; multiorgan failure.
  • VV-ECMO Oxygen indications focus on the ratio of arterial oxygen partial pressure to fractional inspired oxygen (PaO2:FiO2)
  • VV ECMO indicated if PaO2:FiO2 ≥ 150 mmHg and
    • pH < 7.25 with PaCO2 ≥ 60 mmHg for > 6 hours.
  • For those with PaO2:FiO2 < 150 mmHg and
    • PaO2:FiO2 < 80 mmHg for > 6 hours  
    • PaO2:FiO2 < 50 mmHg for > 3 hours
    • pH < 7.25 with PaCO2 >60 mmHg for > 6 hours.
  • Challenges to VV-ECMO include:
    • Prolonged ECMO support requires – up to 3 weeks due to slow lung healing.
    • Systemic inflammation producing a prothrombotic state requiring large heparin and/or bivalirudin dosages.
    • Potential ECMO induced advancement of of COVID – 19 to other organ systems.
  • Hemodynamic Support for the Management of Cardiogenic Shock
    • Optimal for left ventricular failure from a viral myocarditis – as an isolated organ problem.
  • Goals of Support
    • To provide adequate tissue perfusion (To break the shock spiral)
    • Unload the injured ventricle serving as a bridge to recovery, transplant or a permanent device.
  • Potential Devices:
    • Veno-arterial ECMO (VA-ECMO)
  • Advantages – can be implanted at bedside and provides full, biventricular support
  • Disadvantages – Lack of ventricular unloading adversely effecting left ventricular recovery (LV) while increasing risk of lung injury, risk of aortic/LV thrombosis as well as hemolysis. Lastly, it is unable to uncouple the left and right ventricles challenging the ability to predict next requirements. Ambulation generally not possible.
    • Impella
  • Advantages – Completely unloads the LV, protecting the lungs. Long term support is possible beyond one month with the larger devices. In addition, it has a low rate of hemolysis Ambulation is feasible with axillary cannulation (often surgical).
  • Disadvantages – Surgical implantation requires surgery and transesophageal echocardiogram for placement which possibly increases increased risk to personnel.
    • Temporary right-ventricular assist devices (RVADs)
  • Device types – ProtekDuo/TandemHeart, CentriMag and Impella RP
  • An oxygenator can be spliced in to provide an oxy-RVAD configuration.
  • Specific management:
    • Combined devices – Frequently beneficial – VA ECMO with combined Impella for unloading.
    • Heart Team Decisions critical
  • Summary
    • In appropriately selected patients, particularly with COVID – 19, these devices can be lifesaving.

Safe Reintroduction of Cardiovascular Services during the COVID-19 Pandemic: Guidance from North American Society Leadership – Part 2 Focusing on Invasive Cath Lab Procedures Part 2 of 2

Key Points:

The authors introduced a table of considerations for the level at which to reinstitute cardiovascular (CV) Services. Levels of patient and personnel risk COVID Risk in conjunction with local health officials and hospital capabilities and availability of PPE and other hospital services.

Recommendations are based on 3 Response Levels:

Level 2 – Reintroduction of some services.

  • STEMI – PCI for most patients unless diagnosis unclear and Patient’s COVID Status in question. Exception is lab that routinely treats with thrombolytics.
  • ACS/NSTEMI – PCI for High Risk, Medium Risk – selective decisions and low risk initiate medical therapy.
  • Stable Coronary Artery Disease (CAD): Focus on High Risk, Symptomatic Patients. Stable and moderate risk patients deferred.

Level 1 – Reintroduction of most services.

  • STEMI – Same as Level 2.
  • ACS/NSTEMI – Definite angiography for High-Risk patients and now inclusion of Medium Risk Patients. Low Risk patients – consider selective angiography.
  • Stable CAD – Stable patients with moderate risk. Truly stable patients remain deferred.

Level 0 – Reintroduction of regular services.

  • ACS/STEMI – Same as Level 1 & 2.
  • NSTEMI – Routine management without restrictions.
  • Stable CAD – Routine management

Note: These represent a composite of concepts gleaned from multiple sources, formal Society recommendations, webinars physician discussions aa well as a variety of social medical posts and discussions. These are meant to be considerations and not guidelines nor do they represent the views of any specific society.

General Considerations:

  • Important to minimize need for prolonged hospitalizations and/or ICU bed or ventilator use from complications delaying prompt discharge post an invasive procedure.
  • Importance of minimizing hospital and ICU bed use from procedures as “insurance” against a sudden increase in COVID – 19 use. Maintaining a critical level of protected ICU beds is critical to continued reintroduction of procedures.
  • Minimizing patient risk by scheduling procedures for physicians who are not covering COVID – 19 patients elsewhere and are COVID test negative.
  • Screening patients for COVID – 19 to avoid procedure lab and staff contamination.

Maximizing Through-put considerations:

  • Triage patients to perform procedures on the highest risk patients first.
  • Communicate with further “delayed” patients so they recognize that if symptoms change they notify the Team promptly or seek medical attention promptly depending on the severity of symptoms. This concept seems critical to avoid greater delayed patients assuming they don’t have a problem because of the continued delay and ignoring a symptom change.
  • For a given day’s schedule, arrange patients in the reverse order of the likely risk of a complication – doing the most complex last (I know it seems counter-intuitive) but the goal is to get as many patients done before a possible ICU admission might truncate the remainder of a day’s schedule.

Procedure Considerations to minimize hospital days:

Review patient’s clinical and procedure parameters carefully before proceeding. The goal is to development a plan to optimize outcomes while minimizing risk of complications. (Thus, minimizing use of hospital ICU and general beds). It is important to balance optimal outcomes with safety.

Important factors to assess:

  • Bleeding risk
  • Optimal access site(s) based on vascular disease, bleeding risk and operator and lab experience
  • Consider a closure device if anatomically feasible and operator is experience. This is not the time for on-job training.
  • Risk of acute kidney injury (AKI).
  • Hydrate well and be sure hemodynamically stable with compensated heart failure.
  • Extent of revascularization needed – while “staging” maybe seen as a simple way to reduce risk but staging adds to total procedures and additional hospital days. Complete revascularization is the standard for optimal outcomes and is optimally accomplished at a single setting – And reduces hospital days.
  • A useful consideration is to use p-VAD (Impella) hemodynamic support for high-risk cases to increase the probability of ideal outcomes in terms of completeness of revascularization, optimal lesion results and potentially reducing the risk of AKI. Optimal results reduce initial hospital time but also reduce the need for repeat hospitalizations for complications such as acute stent closure.
  • Post-procedure before discharge, optimize patient education and availability of needed medications – again to maintain a good outcome and lessen readmission.
  • Insure family support and follow up including contact for questions.

A final thought:

  • While all of these measures are important in the current reintroduction of cardiac procedures, all of them support sound practice principles so that optimizing through-put is not a “tainted” business concept but supports good practice.

Safe Reintroduction of Cardiovascular Services during the COVID-19 Pandemic: Guidance from North American Society Leadership Part 1 of 2

Wood DA, Mahmud E, Thourani VH, et.al. Safe Reintroduction of Cardiovascular Services during the COVID-19 Pandemic: Guidance from North American Society Leadership, Journal of the American College of Cardiology (2020), doi: https://doi.org/10.1016/ j.jacc.2020.04.063.

Key Points:

  • A consortium entitled the North American Cardiovascular Societies has published a document describing considerations in reestablishing cardiovascular (CV) services in the setting of COVID – 19.
  • The need for CV services is critical as many stable but high-risk patients have been deferred along with more routine cases, all potentially magnified by a subset of patients who have deferred seeking evaluation or treatment who are likely to present with more complex or serious and/or acute problems.

A Summary of strategies include:

  • Ethical considerations – should include care decisions based on maximum benefit vs. risk of spreading the virus emphasizing that decisions should be fair given various ethnic and social risks.
  • Decisions must be made in conjunction with local and regional public and other healthcare administrations and leaders to assure plans meet the needs of a community while representing the needs of high-risk CV previously deferred patients.
  • Imperative in the decision process is the protection of patients and Health Care Workers including appropriate distancing, testing for COVID – 19 prior to non-urgent procedures and effective PPE. Noninfected patients and staff need to be protected from the risk of exposure to COVID – 19 patients.

Part II: Specific Practice recommendations from this document will be presented separately.

Impact of coronavirus disease 2019 (COVID-19) outbreak on outcome of myocardial infarction in Hong Kong, China

Tam C-CF, Cheung K-S, Lam S, et al. Impact of coronavirus disease 2019 (COVID-19) outbreak on outcome of myocardial infarction in Hong Kong, China. Catheter Cardiovasc Interv. 2020;1–4. https://doi.org/10. 1002/ccd.28943

Key Points:

  • Impact of COVID – 19 extends beyond the effects of direct infection to include changes in human behavior which may contribute to acute myocardial infarction (AMI) treatment delays.
  • Patients presenting with AMI (STEMI and NSTEMI) from Queen Mary Hospital in Hong Kong were divided into two groups: 11/1/2019-1/24/2020 (Group 1) and 1/25 – 3/31/2020 (Group 2).
  • Group 1 represents “Baseline” and Group 2 represents a period of time post the Hong Kong COVID – 19 response.
  • Overall average Hospital Emergency Visits declined Group 1 – 327/day vs. Group 2 – 231/day.
  • Of 149 patients with AMI during this time, Group 2 patients tended to present later relative to first medical contact to door time.
  • There was a non-significant trend to more deaths for Group 2 with later delays in seeking treatment.
  • For group 2 patients, the composite of in-hospital death, cardiogenic shock, mechanical circulatory support and VT/VF were significantly higher for Group 2.
  • Multiple factors may contribute to these outcomes but clearly a treatment delay seems to play a significant impact on these results.

Unique Patterns of Cardiovascular Involvement in COVID-19

Hendren NS, Grodin JL, Drazner MH. Journal of Cardiac Failure (2020).  doi: https://doi.org/10.1016/j.cardfail.2020.05.006

Key Points:

  • The authors describe an acute COVID-19 cardiovascular syndrome, termed ACovCS reflecting the cardiovascular and thromboembolic complications.
  • These complications include:
    • Acute coronary syndrome with coronary obstructive disease (CAD)
    • Acute myocardial injury without CAD
    • Heart failure
    • Cardiogenic Shock
    • Myocarditis
    • Plus – Arrhythmias, pericardial effusions, cardiac tamponade
  • Thrombotic complications include stroke, pulmonary embolism and deep vein thrombosis.
  • Cardiovascular Presentations can infrequently be isolated but more commonly occurs in conjunction with typical pulmonary disease
  • Distinguishing the groups can be a challenge but markers such as troponin can be helpful as to true cardiac vs. a primary pulmonary presentation.
  • For patients with predominant cardiac disease shock is likely cardiac as opposed to predominant Pulmonary cases where the shock may be more likely septic.
  • Multiple clinical, genetic, environmental and social factors determine the risk of as well as the severity of infection.
  • Categorization by this format should allow an effective diagnosis, treatment, and future research.

Poll Results: Updating CV Management in the Face of COVID-19: Decisions About a Return to Normalcy

Vetrovec GW.  ACC.org Interventional Section online 5/13/2020

Key Points:

Attached Poll addressed “returning to Normal” for in and outpatient cardiovascular care.

Relative to in-patient STEMI Management, fewer than 8% are using thrombolytics as a primary treatment of STEMI and the remainder are using or continuing Primary PCI (over 60%) while one third are still making decisions on a case by case basis.

Regards outpatient management, roughly two-thirds favored beginning testing with the majority including invasive testing in the plan. One third were still awaiting COVID – 19 numbers before proceeding.

The time frame for this poll was the past two weeks so a current poll might be somewhat more progressive.

Overall the results are favorable for a move to normalcy.

Recognizing Right Ventricular Dysfunction in COVID-19 Related Respiratory Illness

Milligan GP, Alam A, Guerrero-Miranda C.  Journal of Cardiac Failure published on line: https://doi.org/10.1016/j.cardfail.2020.05.00

Key Points

  • In COVID – 19, Echoes may be limited in scope for safety so specific findings are important.
  • The mechanism of Acute Cor Pulmonale (ACP) occurs in the setting of ARDS secondary to hypoxemia, pulmonary edema and microvascular thrombosis producing acute right ventricular (RV) afterload.
  • Biomarkers (Troponin and brain natriuretic) predict extent of D-dimer elevation and mortality, recently confirmed at autopsy with micro pulmonary thrombosis.
  • ACP findings on point of care echocardiograms ultrasound:
    • RV enlargement on apical 4 chamber view with RV area >60% of Left Ventricular (LV) area at end-diastole.
    • A “D-shaped” ventricular septum caused by a lengthened RV contraction best seen in the parasternal short axis at end-systole
    • Reduced systolic excursion of the tricuspid annular plane.
    • McConnell’s sign (Regional RV dysfunction characterized by akinesia in mid free wall but preserved apical wall motion.) A specific echocardiographic sign of acute pulmonary embolism.
  • The authors recommend use of a right heart catheterization to optimally understand the complex and conflicting hemodynamics of hypoxemic pulmonary vasoconstriction and elevated positive end-expiratory pressure (PEEP) impacting RV preload and afterload.
  • A pulmonary artery catheter can support optimization of cardiac output, RV preload as well as pulmonary vascular resistance based on choosing and titrating treatments such as inhaled pulmonary vasodilators and inotropic support while limiting the potential risk of adverse complications such as cardiogenic pulmonary edema.
  • The authors recommend determining and treating the specific cardiac abnormalities, emphasizing that the RV, not infrequently, is the most effected chamber requiring support.

Elevated Troponin in Patients With Coronavirus Disease 2019: Possible Mechanisms

TERSALVI G, VICENZI M, CALABRETTA D, BIASCO L, PEDRAZZINI G, AND WINTERTON D.

Background:

In China the incidence of Troponin elevation was upwards of 28%, with higher elevations predicting a higher risk of ICU admission and subsequent death. Patients with a troponin elevation are more likely to be elderly and have risk factors of hypertension, coronary heart disease and/or diabetes.

 

Key Points:

 

  • Four possible mechanisms of troponin elevation are presented:
    • Myocarditis – myocardial involvement has been documented with other coronavirus species but so far not with COVID – 19 but presumed myocardial inflammation seems relatively common is likely to represent some cases of troponin elevation
    • Microangiopathy – Damage to small vessels in patients may contribute to troponin elevations along with secondary spasm and thrombotic occlusions. Contributing further is likely a secondary vasculitis that occurs in some patients with elevated troponins.
    • Myocardial Infarction – Likely occurs frequently based on other studies which suggest that plaque rupture from vascular risk or infection could be playing a role in the troponin elevations by a variety of observations.
    • Cytokyne Storm – Potentially a cause to explain the troponin increases. The patents with cytochrome storm havw significant stress on the myocardium.
  • In summary the COVID – 19 virus is very strong which allows a catecholamine surge which contributes to the risk.

ST-Elevation Myocardial Infarction in Patients with COVID-19: Clinical and Angiographic Outcomes

Question: What are the cardiac characteristics of COVID – 19 patients presenting with STEMI.

Population: This report describes the angiographic findings and outcomes of 28 COVID – 19 patients who presented with STEMI from hospitals in the Lombardy Region of Italy.

Key Points:

  • Presentation – 28 patients – 25 with localized ST elevation (89.3%) and 3 with a new LBBB (10.7%).
  • Mean age -68+11 years, 28.6% women, 71.4% men.
  • Risk factors included Diabetes 32.1%, chronic kidney disease 28.6% and prior myocardial infarction 10.7%.
  • STEMI was the first clinical manifestation of COVID in 24 patients (85.7%) and COVID – 19 status was not known at the time of coronary angiography. The other 4 patients developed STEMI during hospitalization.
  • Echocardiography was performed in all patients with 23/28 (82.1%) having segmental wall motion changes.
  • At coronary angiography, 17 (60.7%) patients had a culprit lesion treated with PCI; 11 patients (39.3%) had no significant obstructive disease.
  • At mean follow-up of 13 days, 11 patients died (39.3%); 16 patients (57.1%) were discharged and 1 patient was still hospitalized in the ICU.
  • Thus ~40% of STEMI patients with COVID – 19 had no significant coronary disease reaffirming the potential harm of treating with routine thrombolytics. Data is not available to differentiate type 2 myocardial infarction from COVID – 19 myocarditis or other unique etiologies such as COVID induced endothelial dysfunction and/or myocarditis or cytokine storm.
  • While the numbers are small, the report emphasizes the point that acute STEMI presentations may be quite different in the setting of COVID – 19.

Association of Treatment Dose Anticoagulation with In-Hospital Survival Among Hospitalized Patients with COVID-19

Background: COVID – 19 appears to be associated with a hypercoagulable state manifested by frequent abnormalities of clotting and observed thrombotic clinical events.

Clinical Question: Does the use of systemic anticoagulants (oral, subcutaneous or intravenous) have a positive clinical impact on outcomes for COVID – 19.

Study: Single-center (Mount Sinai Health System in New York City), retrospective analysis of the effect of a therapeutic anticoagulant (AC) treatment dose on the outcome of patients with laboratory diagnosed COVID – 19.

Key Points:

 

  • Of 2773 hospitalized patients with COVID – 19, 786 (28%) were treated with systemic, therapeutic doses of AC at a median time to AC of 2 days.
  • Patients treated with AC had an In-hospital mortality of 22.5% with a median survival of 21 days; patients not receiving AC had a 22.8% mortality with a median survival of 14 days.
  • AC patients more often required mechanical ventilation (29.8 vs. 8.1%, p<0.001).
  • Mechanical ventilation was required in 395 patients with a mortality of 29.1% and a median survival of 21 days for AC patients compared to a mortality of 62.7% and median survival of 9 days for those not receiving AC.
  • Major bleeding was low in both groups with a non-significant increase in bleeding events 3.0% for the AC group compared to 1.9% for the non-anticoagulated patients (p=0.2) including approximately 1/3 of events before the introduction of treatment in the AC group.
  • Bleeding events were more common in intubated patients regardless of whether or not they received AC (7.5 vs. 1.35%).
  • In summary, while this retrospective study has limitations, Given the recognized frequent hypercoagulability of CODID – 19 patients and the associated observed frequent thrombotic events, a prospective analysis of the impact of AC is warranted.

Prognostic Value of Right Ventricular Longitudinal Strain in Patients with COVID-19

Li Y, Li H, Zhu S, Xie Y, Wang B, He L, Zhang D, Zhang Y, Yuan H, Wu C, Sun W, Zhang Y, Li M, Cui L, Cai Y, Wang J, Yang Y, Lv Q, Zhang L, Xie M, Prognostic Value of Right Ventricular Longitudinal Strain in Patients with COVID-19, JACC: Cardiovascular Imaging (2020), doi: https://doi.org/10.1016/j.jcmg.2020.04.014.

Study Question: The right ventricular (RV) is susceptible to acute changes secondary to volume overload. Such changes appear to be a potential predictor of COVID – 19 mortality. Because standard echocardiographic parameters are not optimal to assess such changes, the focus of this report Is whether echocardiographic derived right ventricular longitudinal strain (RVLS) is a useful predictor to identify right ventricular function changes as a risk for adverse COVID 19 outcomes.

Key Points:

  • Consecutive echocardiograms from 120 consecutive patients with COVID – 19 were analyzed.
  • RVLS was categorized by tertiles of RV function compared to standard RV echocardiographic parameters.
  • Patients in the highest tertile of RVLS were more likely to multiple risk factors for adverse outcome in conjunction with RV failure including higher D-dimer, invasive mechanical ventilation, greater acute heart injury, acute respiratory distress syndrome (ARDS), deep venous thrombosis and mortality.
  • Of 18 patients who died, non-survivors demonstrated greater RV enlargement, RV dysfunction and pulmonary artery elevations of systolic pressure.
  • RVLS was determined to be a useful predictor of RV dysfunction and worse COVID-19 survival.
  • The challenge is to better utilize early recognition of RV dysfunction as a predictor of adverse outcome and intervene early with novel strategies of RV support to hopefully change the course of this patient population.

Pulmonary Embolism in COVID-19 Patients: Awareness of an Increased Prevalence

Key Points:

The authors report an experience of high risk of pulmonary embolism in the setting of COVID – 19 ICU patients – the details of their preliminary observation follow.

  • Reported population: 197 confirmed COVID – 19 patients with an ICU Pneumonia admission.
  • Pulmonary Embolus (PE) was diagnosed in 20.6% within 1-18 days, medial 6 days during the ICU admission.
  • A Comparison group of 196 patients from the same period in 2019 had a 6.1% incidence of PE.
  • Thus, the COVID – 19 population showed an absolute increase in the PE incidence of 14.4%.
  • A second comparison noted the risk of PE (7.5%) was half as frequent in 40 ICU admissions for Influenza in late 2019.
  • COVID – 19 patients D-Dimers, plasma factor VIII activity and factor Willebrand antigen levels consistent with an increased risk of PE.
  • When diagnosed with PE, 20/22 COVID – 19 patients were on Guideline recommended prophylactic antithrombotic treatment (UFH, LMWH). In addition, one patient was on UFH for atrial fibrillation and one patient was on therapeutic fluindione (a vitamin K antagonist) for DVT.
  • The associated incidence of DVT was lowest in the COVID – 19 group compared to the other two groups.
  • The report has potential biases – first, the decision to perform Computer Tomography Pulmonary Angiography was based on clinical decisions, not for the entire populations: in addition, the population tends to be obese which could impact results.
  • In summary, this preliminary report form France suggests that ICU patients with COVID -19 infection are at significantly increased risk for acute PE despite prophylactic anticoagulants.

Out-of-Hospital Cardiac Arrest during the Covid-19 Outbreak in Italy

The Authors explored the incidence and characteristics of out of hospital cardiac arrests (OHCA) in 4 regions of the Lombardy region of Northern Italy using the Lombardia Cardiac Arrest Registry for the first 40 days of the outbreak between 2/21/2020 (first regional case 2/20/2020) to 3/31/2020. These statistics were compared to the same 40 days in 2019. There findings are as follows:

Key Points:

  • During the 2020 Period 362 cases OHCA were identified, compared with 229 cases in 2019 (an increase of 58%).
  • Medical causes and at home events increased 6.5 and 7.3% respectively with a 11.3% increase in unwitnessed OHCA.
  • In 2020, median EMS arrival time was 3 minutes longer.
  • Bystander CPR was 15.6% lower in 2020.
  • In patients with an EMS resuscitation attempt in 2020, out of hospital death was 14.9% higher.
  • The cumulative incidence of OHCA was highly associated with the COVID – 19 cumulative incidences.
  • Overall there were 133 additional OHCA events in 2020 of which 103 were suspected COVID patients (87) or known COVID patients (16).
  • Thus, the 77.4% increased incidence of OHCA in 2020 was reasonably accounted for by COVID – 19 infection.
  • Nearly one fourth of the OHCA events otherwise not accounted for in the Lombardia Region are likely attributable in part to acute STEMI (and potentially other potentially lethal acute events). It is likely that most of this increase in mortal events reflect patients not seeking prompt medical attention for acute symptoms because of fear of COVID – 19 exposure if seen at a hospital.

Advanced Pulmonary and Cardiac Support of COVID-19 Patients: Emerging Recommendations From ASAIO—A “Living Working Document”

The authors provide a comprehensive review of the pathophysiology, diagnostic issues, pharmacology, mechanical pulmonary, cardiac support and COVID -19 ASAIO Recommendations emphasizing the treatments for ARDS. The latter topics are what make this document most useful and educational for all clinicians. These latter topics are the focus of the Key Points.

Key Points:

  • There are tradeoffs between optimal and what’s available. What follows is a stepwise outline of therapies reflecting the usual progression recognizing variation occur which require modifications.
  • Pulmonary Support
    • Non-invasive (ex. CPAP/BIPAP) is acceptable for moderate hypoxemia.
    • Invasive ventilation with limits on end tidal volume and pressure in ARDS.
    • Prone position mechanical ventilation is often used for ARDS to improve basal lung aeration.
  • Pulmonary and cardiac support
    • Persistent hypoxemia – consider extracorporeal and membrane oxygenation for systemic oxygenation commonly provided by V-V ECMO.
    • Cardiogenic shock occurs in a subset of COVID – 19 patients and in salvageable patients warrants focus on left ventricular function which is not always accurately portrayed by LVEF alone, prompting a clinical assessment of adequacy of both right and left cardiac performance.
    • While V-V ECMO supports oxygenation in the setting of cor pulmonale, direct RV support is necessary to increase right sided output. Likewise, LV support is needed for cardiogenic shock and maybe provided by V-A ECMO as well as biventricular support using V-V ECMO and pVAD (Impella) for LV support.
    • Conversely if total support is provided by V-A ECMO, use of pVAD (Impella) is ideal to unload the LV; the so-called ECPELLA configuration. The Impella use provides an opportunity for prolonged LV support, while potentially minimizing complications.
  • These are challenging, often prolonged cases in patients who commonly have significant co-morbidities. Institutions are somewhat limited by their capabilities and realistic expectations for an individual patient’s probable recovery.

ACC Poll Results: Another Take on STEMI During the Pandemic

Given anecdotal and published reports of decreased STEMI presentations in the face of COVID – 19 infection, a recent ACC.org Poll investigated US respondents assessment of STEMI numbers and extended the question to better understand suspected reasons for the reduced numbers of STEMIO presentations.

  • Overall there were just at 500 responses to the two questions:
    • Have you noted a decline in STEMI and NSTEMI admissions to your hospitals?
    • If reports of fewer STEMI and NSTEMI cases are confirmed, what is the most likely reason?
  • 6% noted no change, 23% noted a <50% decline while over 50% of respondents thought there had been more than a 50% decline, including 15% who noted their hospital was seeing no MIs.
  • Regards reasons for the decline – 50% thought the issue was under-recognition due to delayed presentations.
  • About 18% thought the decline was the result of patients going to smaller, less crowded hospitals.
  • 32% of respondents thought the reduction was secondary to less events due to less job stress with shelter in place orders.
  • The findings of lower hospital STEMI events seems broad-based including reports from Europe and the USA, while the reasons are less clear but likely relate to patients not seeking appropriate care – a challenge that needs significant public education

NEJM Correspondence – Neurologic Features in Severe SARS-CoV-2 Infection

Helms J, et. al. Neurologic Features in Severe SARS-CoV-2 Infection: Letter to the Editor, NEJM. Published April 15, 2020: DOI: 10.1056/NEJMc2008597.

Study Background: The authors describe neurologic features identified in two French Hospitals between 3/3-4/3/2020 comprising 64 patients admitted with COVID – 19 acute respiratory distress syndrome (ARDS). The report encompasses the 58 patients who were evaluated in the ICU without neuromuscular blockade at the time of examination by an intensivist and had a neurological evaluation before death. Median age was 63 years and the SAP Score II was 52 (scale ranges form 0-163, with higher values reflecting greater illness severity). Seven patients had prior neurological diagnoses including partial epilepsy, mild cognitive impairment and transient ischemic attack. Surprisingly only 8/49 (16%) patients had fever at the time of examination making this an unlikely cause of the neurological findings and reaffirming the low reliability of this finding for general screening.

Key Points:

  • Analysis was complicated by timing of patient examination: 8(14) on admission before treatment, 39 (67%) after sedation and neuromuscular blockage were withheld.
  • Overall 49/58(85%) of patients exhibited neurological signs
  • Agitation was diagnosed in 40(69%) of patients when sedation and neuro-blockage was withheld.
  • Confusion was diagnosed in 26 of 40 patients (65%).
  • Diffuse cortical tract findings including enhanced tendon reflexes, clonus and bilateral extensor plantar reflexes were noted in 39 patients (67%).
  • A dysexecutive (inattention and/or disorientation) was present in 15 of 45 patients (33%).
  • MRIs were performed in 13 patients. Despite no focal signs of stroke, hypo perfusion was seen in 11/13 patients and 8 patients had leptomeningeal spaces. Two asymptomatic patients had evidence of a small acute ischemic stroke and one patient a subacute stroke.
  • Of 8 patients who underwent an EEG, only nonspecific changes were detected.
  • Spinal fluid analysis was performed in 7 patients showed no cells and all were negative for SARS-CoV-2 virus.
  • In summary, the incidence of incidence of encephalopathy (confusion and nonspecific neurological findings) was frequent and included a small number of patients with focal findings of acute or subacute ischemic stroke on MRI scanning.
  • There is insufficient data to know the contribution of SARS-CoV-2 virus, acute illness, cytokines or medication withdrawal to these findings.

Several other reports have noted stroke and a variety of neurological findings in COVID – 19 patients, emphasizing the need to be vigilant in these patients for neurologic complications.

Presenting Characteristics, Comorbidities, and Outcomes Among 5700 Patients Hospitalized With COVID-19 in the New York City Area

Richardson S, Hirsch JS, Narasimhan M, Crawford JM, McGinn T, Davidson KW, and the Northwell COVID-19 Research Consortium. JAMA. doi:10.1001/jama.2020.6775Published online April 22, 2020. Corrected on April 24, 2020.

This report describes COVID – 19 patient outcomes for patients admitted to the Northwell Health System from 12 hospitals including New York City, Long Island and Westchester County, New York March 1 – April 4, 2020. There were 5700 admissions of which 2634 were discharged Alive or died by April 4, with the remainder still hospitalized.

Key Points:

  • Of the 5700 admissions, mean age was 63 yrs. with 61% males consistent with other studies demonstrating a male preponderance of cases.
  • Common comorbidities parallel other reports including hypertension (56.6%), obesity (41.7%), and diabetes (33.8%).
  • Presenting clinical findings included Fever (30.7%), respiratory rate >24/min (17.3%) with supplemental O2 in 27.8%. Respiratory co-infection occurred in 2.1%. Thus, fever is not a predominant finding in hospitalized patients.
  • Of the 2634 patients discharged dead or alive during the study period, 14.2% these patients had ICU admissions (mean age 68 yrs, 66.5 % male). Mechanical ventilation was used in 14.2% of patients (86% of patients admitted to the ICU) with 3.2% requiring renal replacement therapy.
  • Mortality was 21% for the 2634 patients discharged dead or alive by April 4, highly related to having been on mechanical ventilation (88% mortality) and for age >65 years.
  • For patients discharged alive, lymphocyte values tended lower with older age.
  • These data parallel data from other studies re-emphasizing the risk for patients requiring ICU admission and mechanical ventilation, being over age 65 and male.

Management of Acute Myocardial Infarction During the COVID-19 Pandemic

Key Points:

  • Reassure public that safeguards are available to minimize patient exposure to COVID – 19 in the hospital setting.
  • Patients should continue to use the 911 EMS system for symptoms suggestive of acute ischemic symptoms suggesting a heart attack to assure appropriate care.
  • Adhere to optimal protection for medical personnel including PPE and masking patients.
  • Primary PCI is the standard of care for definite STEMI. After PCI of the culprit artery, PCI of other
  • In the setting of COVID – 19 presentations may be deceptive – thus a careful assessment before going to the cath lab is warranted for patients with diffuse ST – Segment Elevation which might represent acute myocarditis, coronary spasm or other non-traditional presentations which have been reported in COVID – 19 patients and represent cases in which primary thrombolytic treatment would have risk without benefit.
  • Patients with severe respiratory dysfunction consistent with ARDS requiring ventilation with multiple co-morbidities may be considered for supportive only care because of a high mortality risk
  • Thrombolytic therapy can be considered for patients seen at a non-PCI center unable to be transported to a Primary PCI Center within 120 minutes (current standard recommendation). If thrombolytic treatment is utilized, transfer to a PCI Center is recommended (current guideline) after a phone discussion with the potential accepting center.
  • Patients with Cardiogenic Shock and ST Elevation STEMI are considered for urgent invasive therapy and possible hemodynamic support with consideration for intubation before entering cath lab to reduce risk of viral spread with sudden cardiac arrest.
  • Patients without of hospital cardiac arrest (OHCA) should be considered for invasive management if they have elevated ST – Segments consistent with infarction and wall motion abnormalities on echocardiography.
  • Non-Acute STEMI patients with OHCA should only be considered if hemodynamically unstable.
  • NSTEMI should be managed medically unless hemodynamically unstable or have high risk characteristics – Grace Score > 140.
  • Safety remains of utmost importance – ideally with a designated cath lab (and negative pressure if available) for these patients and appropriate PPE for all involved.

COVID-19 pandemic and cardiac imaging: EACVI recommendations on precautions, indications, prioritization, and protection for patients and healthcare personnel

Skulstad H, Cosyns B, Popescu BA, et. al. European Heart Journal – Cardiovascular Imaging (2020) 0, 1–7 doi:10.1093/ehjci/jeaa072

Key Points (For patients with suspected or confirmed COVID – 19 Infection)

  • Target studies to cases in which an imaging test can provide clinically important management information using the most appropriate modality to obtain the needed information.
  • Recognize and assess the risk of a study to personnel or equipment relative to the contamination of personnel and/or other patients related to transportation.
  • Appropriate personnel protective practices and thorough and complete equipment cleaning between cases are critical for ultimate safety.
  • Consider Bedside echocardiography (including POCUS) with limited/focused studies to answer the specific question being addressed. TEE high risk for personnel exposure – consider alternative imaging modalities.
  • Chest CT with modifications can be useful for multiple evaluations; pneumonia and coronary anatomy.
  • Left ventricular can be assessed during coronary angiography.
  • CMR for myocardial metabolic functional evaluation – particularly assessing myocarditis is an important to modality.

The New Pandemic Threat: People May Die Because They’re Not Calling 911 There has been a dramatic decrease in Myocardial Infarction presentations worldwide during the current COVID – 19 Pandemic.

Key Points:

  • There has been a dramatic decrease in Myocardial Infarction presentations worldwide during the current COVID – 19 Pandemic.
  • Multiple reasons for the reduction in infarctions have been postulated but a worrisome and likely significant one is that patients don’t seek care promptly, if at all for symptoms of a heart attack.
  • This “New Pandemic Treat” Statement is signed by multiple organizations and is directed to patients – emphasizing the importance of immediately seeking treatment for important heart attack and stroke symptoms.
  • Perhaps as physicians are communicating with patients remotely, healthcare professionals might consider downloading and distributing this statement to their patients to combat an important, “indirect” COVID – 19 risk!
  • Pass this statement on – its an inexpensive but important “Vaccine” – A 911 Call.

The Untold Toll — The Pandemic’s Effects on Patients without Covid-19

Lisa Rosenbaum, M.D. NEJM DOI: 10.1056/NEJMms2009984 Published April 17, 2020.

  • Dr. Rosenbaum’s comments are in the New England Journal of Medicine’s Medicine and Society Section and succinctly points out with case examples patients who because of the understandable focus on COVID – 19 as a disease and as a risk to patients and medical staff receive non-standard care for non-COVID – 19 related serious medical problems. Examples include
  • Patients with serious cancers who either feel to have missed the value of a “real” multidisciplinary (and usually “face to face”) discussion of options and plans or even potential delays in treatments with unknown consequences.
  • Patients with potentially life-threatening Acute Coronary Syndromes who present with accelerated symptoms but without ECG/Biomarker evidence of infarction are sent home – and only if fortunate to return in time and undergo appropriate coronary angiography.
  • A patient whose delay in care for acute myocardial infarction, awaiting assessment of COVID – 19 status (ultimately negative) led to progressive deterioration with cardiogenic shock and ultimately death.
  • These are not examples from a remote or rural location but from top tier, major medical centers –
  • Reasons include concerns about availability of PPE for staff and a general concern about how to manage no COVID illness in the wake of a Pandemic.
  • A recent study (Garcia S, Albaghdadi MS, Meraj PM, et al. Reduction in ST- segment elevation cardiac catheterization laboratory activations in the United States during COVID-19 pandemic. J Am Coll Cardiol 2020 April 9 (Epub ahead of print) demonstrated a 38% reduction in STEMI procedures since the onset of the COVID – 19 Pandemic.
  • The focus of risk/benefit in patient care has at times moved from patient to staff in the current Pandemic.
  • Dr. Rosenbaum concludes with two comments:
    • “Humanity absent sound medical judgment is meaningless.”
    • “Yet as we begin to observe fewer admis- sions for common emergencies such as heart attack and stroke, … the need for vigilance about viral transmission need not detract from an equally important message: Covid or no Covid, we are still here to care for you.”
  • Standard diseases in the setting of COVID – 19 still exist and still require standard treatments – our challenge is to provide that care safely (for all involved), compassionately, and appropriately.

First successful treatment of COVID-19 induced refractory cardiogenic plus vasoplegic shock by combination of pVAD and ECMO: A case report

Xavier Bemtgen, Kirsten Krüger, David Alexander Supady, et.al: ASAIO Journal Publish Ahead of Print
DOI: 10.1097/MAT.0000000000001178

Case History:

The authors present a 52 y.o. COVID – 19, male patient with a known dilated cardiomyopathy, systolic heart failure and a recent admission for worsening heart failure complicated by a myocardial infarction. The current admission was prompted by cough and shortness of breath. The patient rapidly deteriorated secondary to development of Adult Respiratory Distress Syndrome (ARDS) requiring mechanical ventilation. His course was further complicated by combined cardiogenic and vasoplegic shock (C.I. = 1.8L/min/m2) unresponsive to high doses of vasopressors. On day 3, because of inability to control the shock plus the development of renal failure, a pVAD (Impella CP Smart Assist) was implanted in the cath lab providing 3.5l/min of flow. Lactate normalized and left ventricular end diastolic dimension (LVEDD) diminished. However, the vasoplegic shock persisted requiring continued high dose vasopressors. A V-A ECMO was added day 4 providing 4.5L/min flow. By Day 7 the vasopressors could be withdrawn and the ECMO was changed to a V-V configuration with continued hemodynamic support provided by the Impella. The Impella was successfully weaned at day 19, but V-V ECMO support persists at day 24 suggesting ARDS may be the most resistant of the COVID – 19 complications in this patient.

Link to PDF

Key Points:

  • First case report of pVAD (Impella) combined with ECMO for treatment of refractory cardiogenic and vasoplegic shock in a COVID – 19 patients presenting with ARDS.
  • This case supports the experience that patients of all ages are potentially at risk for severe COVID Complications which are further exacerbated by pre-existing cardiac complications as this patient has coronary artery disease, prior myocardial infarction and a dilated cardiomyopathy with heart failure.
  • Severe shock, cardiac and vasoplegic occur in ARDS patients.
  • Impella CP support rapidly normalized lactate levels and reduced LVEDD, consistent with Left Ventricular unloading.
  • Combined ECMO flow supported oxygenation and provided support to overcome the severe vasoplegic shock, but primarily supported long-term oxygenation.
  • Impella provided the necessary hemodynamic support for cardiogenic shock as measured by lactate reduction with associated favorable left ventricular unloading.

ST-Segment Elevation in Patients with Covid-19 — A Case Series

Key Points: ST-Segment Elevation in Patients with COVID-19 — A Case Series

Sripal Bangalore, M.D., M.H.A. Atul Sharma, M.D.
Alexander Slotwiner, M.D. New York University Grossman School of Medicine New York, NY

Report of patients with documented COVID – 19 from 6 New York Hospitals with ST-elevation on ECG.

  • Non-coronary related myocardial injury was defined by a non-obstructive coronary angiogram or in patients not undergoing coronary angiography having no wall motion abnormalities via echocardiography.
  • Patient Population – Patients – 18; Mean age – 63 years; Men-83%
  • ST-Elevation on admission – 10 ((56%), In Hospital – 8 (44%, median 6-days post-admission); Only 33% had chest pain at the time of ST-Elevation.
  • Focal ST-segment elevation was present in 14 patients (78%) – 5 (36%) with normal LVEF despite regional wall motion abnormality in 1 (20%); 8 patients (57%) had a reduced LVEF – regional wall motion abnormalities were present in 5 (62%). (one patient had no echocardiogram);
  • Diffuse ST-segment elevation was present in 4 (22%) patients; Normal LVEF with normal wall motion – 3 (75%) patients; LVEF was 10% in one patient with global hypokinesis with an LVEF of 10%.
  • Coronary Angiography was performed in 9 (50%) patients; Coronary Obstruction was identified in 6 patients (67%) with PCI in 5 (56%) patients.
  • Clinical Diagnosis of Myocardial Infarction – 8 (44%) of patients had higher median peak troponin levels and d-dimer levels than the 10 patients (56%) with myocardial injury unassociated with coronary artery disease.
  • Hospital Mortality was 72% (13 of 18 patients) – 4 with diagnosed, traditional myocardial infarction, 9 with non-coronary myocardial injury.
  • The etiologies of Myocardial Infarction versus diffuse Myocardial Injury remain unknown and are likely multifactorial given that the presentations were very diverse); Proposed mechanisms include ruptured coronary plaque, hypoxic injury, coronary spasm, microthrombi, direct endothelial and/or cytokine storm.
  • Of note, all 18 patients had elevated d-dimer values which have been observed in other COVID – 19 Reports.
  • In summary, patients with ST-segment Elevation are high risk despite divergent etiologies which can be coronary occlusion or diffuse myocardial injury. Management remains challenging, but invasive diagnosis may be frequently required to understand and potentially treat the underlying process.

Reduction in ST-Segment Elevation Cardiac Catheterization Laboratory Activations in the United States during COVID-19 Pandemic

Journal Pre-Proof

Key Points:

  • Data gathered from 9 US centers with greater than 100 PCIs per year
  • March 1, 2020 defined as date of onset of “After COVID” (AC) Before March 1, considered “Before COVID” (BC)
  • The “control” BC time frame was January 1, 2020 – February 29, 2020 -14 months
  • There is a 38% (95% CI: 26-49; p<0.001) reduction in Cath Lab STEMI activation since the onset of COVID – 19
  • Total Site monthly activation for all centers BC was > 180 per month (Av. 23.6 activations/month); AC Site activation was 138 (mean 15.3 per month)
  • Reduction in US STEMI activation parallels the reduction of 40% in Spain (Rodríguez-Leor O, et al. REC Interv Cardiol. 2020) posted separately on this A-Cure site
  • The authors note that with given social stress, an influenza-like illness and potential “false-positives”, one would have expected an increase in activations.
  • Potential causes for a decline (despite ACC/SCAI recommendation to continue primary PCI as standard STEMI management despite the Pandemic) include:
  • avoidance of contacting Medical Systems 2nd to concerns of COVID -19 exposure in a hospital
  • Misdiagnosis of STEMI
  • Pharmacological reperfusion to protect medical staff from COVID-19 infection possible related to limited PPE.
  • Close monitoring and reevaluations of treatment strategies including supporting guideline recommendations will be critical going forward to insure that STEMI patients receive appropriate management.

Case report – First Documented, Biopsy proven, Myocarditis with Coronavirus Involvement

  • Flu-like symptoms become acute respiratory failure complicated by Shock with reduced Left Ventricular Ejection Fraction (LVEF) (25%) with lymphopenia and leukocytosis and positive inflammatory markers and cardiac markers (hs‐TnI-4332 ng/L).
  • Mechanical ventilation, IABP and V-A ECMO were instituted for hemodynamic and respiratory support.
  • Coronary Angiography was non-diagnostic and Endomyocardial Biopsy pathology demonstrated low‐grade myocardial inflammation with an absence of myocyte necrosis. Coronavirus particles were found in macrophages and interstitial cells but viral particles were not definitively identified in cardiac myocytes.
  • Cardiac function recovered by day 5 and ECMO and IABP were removed
  • On day 13, the patient acutely developed Gram-negative sepsis without cardiac decompensation and died of septic shock.
  • Interpretation of the Biopsy findings
  • While the clinical presentation was consistent with an acute necrotizing, inflammatory myocarditis, the pathology demonstrated only mild inflammation without necrosis. Viral particles were found in the lungs and based on prior viral illnesses (MERS‐CoV), viral particles frequently appear in other organs. However, no vascular involvement was observed.
  • The authors hypothesize that cardiac involvement occurred secondary to a viremia or by an extra-pulmonary transfer of virus via macrophages into the myocardium.
  • This is a single case. More are needed to confirm and add to these findings, but the current case illustrates an early viral involvement with a likely later inflammatory response that can lead to large cytokine release.
  • Hemodynamic and respiratory support potentially with Interleukin treatment may reduce the severity of the illness

Poll Results: COVID-19 and Interventional Cardiology- ACC

Key Points:

 

 

Results of a poll posted on the Interventional Section of ACC.org over the last two weeks assessed planned management strategies of patients with diagnosed or presumed COVID – 19 presenting with STEMI or NSTEMI during the Coronavirus Pandemic. The results from over 1800 participants demonstrate:

For STEMI presentations – Treatment choices were thrombolytics (44%) over traditional primary PCI (33%) while 23% thought decisions should be hospital-based.

For NSTEMI presentations – the predominant treatment choice was medical treatment in the absence of Shock (63%), usual card with risk assessment and appropriate early angiography (21%), while 16% thought decision protocols should be hospital-based.

An Interview With an Italian Intensivist on the COVID Experience in Italy – American College of Cardiology

Key Points:

 

 

  • Reaffirms primary presentation is respiratory
  • Cardiovascular Involvement is definite; often myocarditis, but concerns of excluding traditional infarction induced by high inflammatory markers.
  • Use of Hemodynamic support is used selectively, often with V-V ECMO for oxygenation but other considerations include conversion to V-A ECMO with considerations for Impella unloading (ECPella)
  • Challenges in managing cardiogenic shock include limitation of Right Heart Catheterization and the challenges of potentially placing an Impella in the ICU. (See Posted article on A-Cure sight Pappalardo description of ICU Impella Insertion.)
  • Deciding on Resource utilization generally targets patients based on blood pressure levels, pressors required and Left Ventricular Ejection Fraction.

Cardiovascular Implications of Fatal Outcomes of Patients with Coronavirus Disease 2019 (COVID-19)

The publication summarizes multiple areas of focus:

  • Myocardial Injury measured by multiple myocardial and inflammatory markers increases mortality risk – Higher enzyme values = higher mortality.
  • Myocardial markers which stabilized or declined were associated with a lower mortality risk consistent with the importance of aggressive management.
  • Patients with elevated cardiac markers (e.g. Troponin T) and a history of CV disease had nearly twice the mortality risk (69.4%) compared to patients with elevated cardiac markers but no history of CV disease (37.5%).

  • Triage CV patients for early identification and early escalation of care because of the high risk of adverse outcomes.
  • Develop protocols for screening and management to optimize an early response to high-risk CV patients – particularly those who develop Acute Myocardial Infarction and Cardiogenic Shock.
  • Educate staff on inappropriate personal protection use and catheterization lab management.

Association of Cardiac Injury With Mortality in Hospitalized Patients With COVID-19 in Wuhan, China

JAMA Cardiology

Abstract

OBJECTIVE To explore the association between cardiac injury and mortality in patients with
COVID-19.

DESIGN, SETTING, AND PARTICIPANTS This cohort study was conducted from January 20,
2020, to February 10, 2020, in a single-center at Renmin Hospital of Wuhan University,
Wuhan, China; the final date of follow-up was February 15, 2020. All consecutive inpatients
with laboratory-confirmed COVID-19 were included in this study.

MAIN OUTCOMES AND MEASURES Clinical laboratory, radiological, and treatment data were
collected and analyzed. Outcomes of patients with and without cardiac injury were
compared. The association between cardiac injury and mortality was analyzed.

RESULTS A total of 416 hospitalized patients with COVID-19 were included in the final analysis;
the median age was 64 years (range, 21-95 years), and 211 (50.7%) were female. Common
symptoms included fever (334 patients [80.3%]), cough (144 [34.6%]), and shortness of
breath (117 [28.1%]). A total of 82 patients (19.7%) had cardiac injury, and compared with
patients without cardiac injury, these patients were older (median [range] age, 74 [34-95] vs
60 [21-90] years; P < .001); had more comorbidities (eg, hypertension in 49 of 82 [59.8%] vs
78 of 334 [23.4%]; P < .001); had higher leukocyte counts (median [interquartile range
(IQR)], 9400 [6900-13 800] vs 5500 [4200-7400] cells/μL) and levels of C-reactive protein
(median [IQR], 10.2 [6.4-17.0] vs 3.7 [1.0-7.3]mg/dL), procalcitonin (median [IQR], 0.27
[0.10-1.22] vs 0.06 [0.03-0.10] ng/mL), creatinine kinase–myocardial band (median [IQR], 3.2
[1.8-6.2] vs 0.9 [0.6-1.3] ng/mL),myohemoglobin (median [IQR], 128 [68-305] vs 39 [27-65]
μg/L), high-sensitivity troponin I (median [IQR], 0.19 [0.08-1.12] vs <0.006 [<0.006-0.009]
μg/L), N-terminal pro-B-type natriuretic peptide (median [IQR], 1689 [698-3327] vs 139
[51-335] pg/mL), aspartate aminotransferase (median [IQR], 40 [27-60] vs 29 [21-40] U/L),
and creatinine (median [IQR], 1.15 [0.72-1.92] vs 0.64 [0.54-0.78]mg/dL); and had a higher
proportion of multiple mottling and ground-glass opacity in radiographic findings (53 of 82
patients [64.6%] vs 15 of 334 patients [4.5%]). Greater proportions of patients with cardiac
injury required noninvasive mechanical ventilation (38 of 82 [46.3%] vs 13 of 334 [3.9%];
P < .001) or invasive mechanical ventilation (18 of 82 [22.0%] vs 14 of 334 [4.2%]; P < .001)
than those without cardiac injury. Complications were more common in patients with cardiac
injury than those without cardiac injury and included acute respiratory distress syndrome (48
of 82 [58.5%] vs 49 of 334 [14.7%]; P < .001), acute kidney injury (7 of 82 [8.5%] vs 1 of 334
[0.3%]; P < .001), electrolyte disturbances (13 of 82 [15.9%] vs 17 of 334 [5.1%]; P = .003),
hypoproteinemia (11 of 82 [13.4%] vs 16 of 334 [4.8%]; P = .01), and coagulation disorders (6
of 82 [7.3%] vs 6 of 334 [1.8%]; P = .02). Patients with cardiac injury had higher mortality
than those without cardiac injury (42 of 82 [51.2%] vs 15 of 334 [4.5%]; P < .001). In a Cox
regression model, patients with vs those without cardiac injury were at a higher risk of death,
both during the time from symptom onset (hazard ratio, 4.26 [95%CI, 1.92-9.49]) and from
admission to end point (hazard ratio, 3.41 [95%CI, 1.62-7.16]).

CONCLUSIONS AND RELEVANCE Cardiac injury is a common condition among hospitalized
patients with COVID-19 in Wuhan, China, and it is associated with higher risk of in-hospital
mortality.

Surviving Sepsis Campaign: Guidelines on the Management of Critically Ill Adults with Coronavirus Disease 2019 (COVID-19)

Abstract

Background: The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of
a rapidly spreading illness, Coronavirus Disease 2019 (COVID-19), affecting thousands of people around
the world. Urgent guidance for clinicians caring for the sickest of these patients is needed.
Methods: We formed a panel of 36 experts from 12 countries. All panel members completed the World
Health Organization conflict of interest disclosure form. The panel proposed 53 questions that are
relevant to the management of COVID-19 in the ICU. We searched the literature for direct and indirect
evidence on the management of COVID-19 in critically ill patients in the ICU. We identified relevant and
recent systematic reviews on most questions relating to supportive care. We assessed the certainty in the
evidence using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE)
approach, then generated recommendations based on the balance between benefit and harm, resource and
cost implications, equity, and feasibility. Recommendations were either strong or weak, or in the form of
best practice recommendations.

Results: The Surviving Sepsis Campaign COVID-19 panel issued 54 statements, of which 4 are best
practice statements, 9 are strong recommendations, and 35 are weak recommendations. No
recommendation was provided for 6 questions. The topics were: 1) infection control, 2) laboratory
diagnosis and specimens, 3) hemodynamic support, 4) ventilatory support, and 5) COVID-19 therapy.

Conclusion: The Surviving Sepsis Campaign COVID-19 panel issued several recommendations to help
support healthcare workers caring for critically ill ICU patients with COVID-19. When available, we will
provide new evidence in further releases of these guidelines.
