INTRODUCTION Cardiogenic shock is a major cause of death among patients hospitalized for acute myocardial infarction (AMI) with a mortality rate of nearly 50% (1). Although the incidence of cardiogenic shock at admission has remained stable ranging from 5% to 10%, over the last 25 years, it has decreased during hospitalization. Mortality rates have been reduced related to the progressive increase in primary percutaneous coronary intervention (PCI) as the preferred reperfusion strategy (2-6).
