Zusammenfassung: | 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
El shock cardiogénico (SC) es una complicación grave del infarto agudo de miocardio (IAM) y constituye una de sus principales
causas de muerte.
Objetivos: Conocer las características clínicas, estrategias de tratamiento, evolución intrahospitalaria y mortalidad a 30 días del SC
en Argentina.
Material y métodos: Se trata de un registro prospectivo, multicéntrico, de pacientes internados con SC en el contexto de los síndromes coronarios agudos (SCA) con y sin elevación del segmento ST durante 14 meses (1 de agosto 2021 al 30 de septiembre 2022)
en 23 centros de Argentina.
Resultados: Se incluyeron 114 pacientes, edad 64 (58-73) años, 72% hombres. El 76,3% de los casos corresponden a SCA con elevación del segmento ST, 12,3% a SCA sin elevación del segmento ST, el 7% a infarto de ventrículo derecho y el 4,4% a complicaciones
mecánicas. El SC estuvo presente desde el ingreso en el 66,6% de los casos. Revascularización: 91,1%, uso de inotrópicos: 98,2%,
asistencia respiratoria mecánica (ARM): 59,6%, SwanGanz: 33,3%, balón de contrapulsación intraaórtico: 30,1%. La mortalidad
intrahospitalaria global fue 60,5%, sin diferencias entre los SCA con o sin elevación del segmento ST y a 30 |
