Cardiac arrest within the first 24 hours after hospital admission in ST-segment elevation acute coronary syndromes. The ARGEN-IAM-ST registry

Abstract

Background: Cardiac arrest (CA) in the setting of an acute coronary syndrome is an important cause of in-hospital and out-of hospital mortality. Objectives: The aim of this study was to describe the prevalence, clinical characteristics, and in-hospital outcome of patients from the ARGEN-IAM-ST registry with CA within the first 24 hours after hospital admission. Results: The prevalence of CA within the first 24 hours was 7.8% (136/1,754 patients). These patients were older (median age 63 vs. 61 years, p <0.001) and had higher prevalence of cardiogenic shock (42.6% vs., 3%, p<0.01) and of in-hospital mortality (66% vs. 4%, p <0.001). Overall mortality of the registry was 8.8% (154/1754) and 58% occurred in patients with CA within the first 24 hours after admission. Conclusions: Cardiac arrest within 24 hours in patients with ST-segment elevation acute coronary syndrome is a serious event representing 60% of in-hospital mortality.
