Cardiogenic shock in the context of acute coronary syndromes in Latin America (“LATIN Shock”)

Cardiogenic shock (CS) is a serious complication of heart attack and constitutes one of its main causes of death. To date, there is no data on its treatment and evolution in Latin America.

Objectives

To know the clinical characteristics, treatment strategies, evolution and in-hospital mortality of CS in Latin America.

Materials and methods

This is a prospective, multicenter registry of patients hospitalized with CS in the context of acute coronary syndromes (ACS) with and without ST segment elevation for 24 months.

Results

41 Latin American centers participated incorporating patients during the period between October 2021 and September 2023. 278 patients were included. Age: 66 (59-75) years, 70.1 % men. 74.8 % of the cases correspond to ACS with ST elevation, 14.4 % to ACS without ST elevation, 5.7 % to right ventricular infarction and 5.1 % to mechanical complications. CS was present from admission in 60 % of cases. Revascularization: 81.3 %, inotropic use: 97.8 %, ARM: 52.5 %, Swan Ganz: 17 %, intra-aortic balloon pump: 22.2 %. Overall in-hospital mortality was 52.7 %, with no differences between ACS with or without ST.

Conclusions

Morbidity and mortality is very high despite the high reperfusion used.
