Trends and outcomes of different mechanical circulatory support modalities for acute myocardial infarction associated cardiogenic shock in patients undergoing early revascularization.

ABSTRACT:

Background

The use of Mechanical Circulatory Support (MCS) devices in cardiogenic shock (CS) is growing. However, the recent trends in using different MCS modalities and their outcomes in acute myocardial infarction associated CS (AMI-CS) are unknown.

Methods

The national readmission database (2016-2020) was used to identify AMI-CS requiring MCS. Cohorts were stratified as ECMO compared to Impella. Propensity score matching (PSM) was used to remove confounding factors. Pearson's x2 test was applied to matched cohorts to compare outcomes. We used multivariate regression and reported predictive margins for adjusted trend analysis.

Results

Among 20,950 AMI-CS hospitalizations requiring MCS, 19,628 (93.7 %) received Impella vs 1322 (6.3 %) were placed only on ECMO. ECMO g
