COSTA, YANINA CASTILLO e AREA DE INVESTIGACION SAC- GRUPO ARGEN SHOCK et al. Cardiogenic Shock in the Setting of Acute Coronary Syndromes in Argentina: Results from the ARGEN SHOCK 2 Registry. Rev. argent. cardiol. [online]. 2023, vol.91, n.4, pp.251-256. Epub 01-Ago-2023. ISSN 1850-3748. http://dx.doi.org/10.7775/rac.es.v91.i4.20650.
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 myocardial infarction (AMI) 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 AMI, 12.3% to non-ST-segment elevation AMI, 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: 59.6%, Swan-Ganz catheter: 33.3%, intra-aortic balloon pump: 30.1%. Overall in-hospital mortality was 60.5%, with no differences between AMI 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.
