Network meta-analysis of temporary mechanical circulatory support in acute myocardial infarction cardiogenic shock

Abstract

We performed a network meta-analysis of 11 published randomized clinical trials examining the use of temporary mechanical circulatory support (MCS) devices in adults with acute myocardial infarction cardiogenic shock, including 1,053 total patients with an observed in-hospital or 30-day mortality of 40.4%. None of the temporary MCS devices was associated with lower in-hospital or 30-day mortality compared with initial medical therapy or any other MCS device, either individually or in combination. These data do not support the routine use of temporary MCS devices for the purpose of reducing short-term mortality in unselected patients with acute myocardial infarction cardiogenic shock.
