Abstract

Cardiogenic shock is a state of critical hypoperfusion due to impaired cardiac function (1). Ischemia can induce impaired myocardial contraction, which involves a vicious cycle of low cardiac function and hypotension, resulting in systemic tissue hypoperfusion (1,2). Acute myocardial infarction (AMI) is the most frequent cause of cardiogenic shock, accounting for 80% (3). Despite recent advances in early revascularization, cardiogenic shock is still the leading cause of mortality in AMI, and remains high at 40–50% (4-6).
