Cardiogenic Shock in the Setting of Acute Coronary Syndromes in Argentina: Results from the ARGEN SHOCK 2 Registry

pp. 239-245

Abstract

Background: Cardiogenic shock (CS) is a life-threatening complication of acute myocardial infarction (AMI) and constitutes one of the leading causes of death.

Objective: The aim of this study was to investigate the clinical characteristics, treatment strategies, hospital outcome and 30-day mortality of CS in Argentina.

Methods: We conducted a prospective, and multicenter registry of patients with acute coronary syndromes (ACS) with and without ST-segment elevation complicated with CS that were hospitalized in 23 centers in Argentina for 14 months (between August 1, 2021, and September 30, 2022).

Results: The cohort was made up of 114 patients; median age was 64 years (58-73) and 72% were women; 76.3% corresponded to ST-segment elevation ACS, 12.3% to non-ST-segment elevation ACS, 7% had right ventricular infarction and 4.4% had mechanical complications. In 66.6% of cases CS was present on admission. Revascularization: 91.1%, use of inotropic agents: 98.2%, mechanical ventilation (MV): 59.6%, Swan-Ganz catheter: 33.3%, intra-aortic balloon pump: 30.1%. Overall in-hospital mortality was 60.5%, with no differences between ACS with or without ST-segment elevation, and was 62.6% at 30 days.

Conclusion: Morbidity and mortality of CS are high despite the high rate of reperfusion therapy used.
