Clinical characteristics and evolution of patients with cardiogenic shock in Argentina in the context of an acute myocardial infarction with ST segment elevation. Data from the nationwide ARGEN-IAM-ST Registry

Cardiogenic Shock is one of the main causes of death in ST segment Elevation Myocardial Infarc-tion. To know the clinical characteristics, in-hospital evolution and mortality of patients with Cardiogenic Shock. Patients enrolled in the ARGEN-IAM-ST Reg-istry were analyzed. Predictors of Cardiogenic Shock and death during hospital stay were established. A total of 6122 patients were admitted between 2015 and 2022. Cardiogenic Shock was present in 10.75% of cases. Patients with CS were older (64.5 vs 60 years), more females (41% vs 36%), with more antecedents of infarction and a higher prevalence of anterior location of infarction and multivessel disease. They were also less revascularized (88.5% vs 91.5%) and had a higher incidence of failed angioplasty (15.7% vs 2.7%). They also evidenced a higher occurrence of mechanical com-plications (6.8% vs 0.4%), ischemic recurrence (7.4% vs 3.4%) and cardiac arrest on admission (44.8% vs 2.6%). All the differences described showed statistical significance with P < 0.05. Overall mortality was 58% in contrast to 2.77% in patients without Cardiogenic Shock (P < 0.001). Only age, DBT, and early cardiac arrest were independent predictors of shock on admis-sion whereas age, female gender, cardiac arrest on admission and failed angioplasty were independent predictors of death. One out of 10 patients with ST Elevation Myocardial Infarction presented cardio-genic shock. Its clinical characteristics were similar to those described more than 20 years ago. Despite a high use of reperfusion strategy cardiogenic shock contin-ues to have a very high mortality Argentina. (Curr Probl Cardiol 2023;48:101468.)
