Background-—Delivering therapeutic materials, like stem cells or gene vectors, to the myocardium is difficult in the setting of ischemic heart failure because of decreased coronary flow and impaired microvascular perfusion (MP). The aim of this study was to determine if mechanical left ventricular (LV) unloading with the Impella increases coronary flow and MP in a subacute myocardial infarction.

Total Mechanical Unloading Minimizes Metabolic Demand of Left Ventricle and Dramatically Reduces Infarct Size in Myocardial Infarction

BACKGROUND: Left ventricular assist device (LVAD) mechanically unloads the left ventricle (LV). Theoretical analysis indicates that partial LVAD support (p-LVAD), where LV remains ejecting, reduces LV preload while increases afterload resulting from the elevation of total cardiac output and mean aortic pressure, and consequently does not markedly decrease myocardial oxygen consumption (MVO2).

Avoiding hemodynamic collapse during high-risk percutaneous coronary intervention: Advanced hemodynamics of impella support

The rate of performing primary percutaneous coronary intervention in patients with complex coronary artery disease is increasing. The use of percutaneous mechanical circulatory support devices provides critical periprocedural hemodynamic support.

JACC, 2018: Journal of the American College of Cardiology

BACKGROUND Heart failure after an acute myocardial infarction (AMI) is a major cause of morbidity and mortality worldwide.

Left Ventricular Unloading Is Associated With Lower Mortality in Patients With Cardiogenic Shock Treated With VA-ECMO

Schrage, B., et al. (2020). Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is increasingly used to treat cardiogenic shock. However, VA-ECMO might hamper myocardial recovery. The Impella unloads the left ventricle. This study aimed to evaluate whether left ventricular unloading in patients with cardiogenic shock treated with VA-ECMO was associated with lower mortality.

Miyashita, S., et al. (2021). We conducted a meta-analysis of preclinical studies that tested left ventricular assist device (LVAD) therapy for reducing myocardial infarct size in experimental acute myocardial infarction (AMI). The meta-analysis showed that infarct size was significantly decreased by LVAD support compared to control animals.

Percutaneous cardiac support during myocardial infarction drastically reduces mortality: perspectives from a swine model

Feasibility of Early Mechanical Support During Mechanical Reperfusion of Acute Myocardial Infarct Cardiogenic Shock

Although only preliminary, initial experience suggests that rapid door-to-support times are feasible. This approach results in the rapid reversal of the shock state in most patients, allowing operators to obtain TIMI flow grade III rates comparable to those in patients with non-shock ST-segment elevation MI and may improve survival. Given these encouraging pilot data, a large formal quality initiative entitled the Detroit Cardiogenic Shock Initiative has been launched.

Hemodynamic Support With a Microaxial Percutaneous Left Ventricular Assist Device (Impella) Protects Against Acute Kidney Injury in Patients Undergoing High-Risk Percutaneous Coronary Intervention

Acute kidney injury (AKI) is common during high-risk percutaneous coronary intervention (PCI), particularly in those with severely reduced left ventricular ejection fraction. The impact of partial hemodynamic support with a microaxial percutaneous left ventricular assist device (pLVAD) on renal function after high-risk PCI remains unknown.

Although prompt institution of reperfusion following coronary artery occlusion has been shown to limit myocardial infarct size, significant “reperfusion injury” may result.
