Coronary angiography characteristics of out-of-hospital sudden cardiac arrest occurring in sport-related acute myocardial infarction

Abstract

Although out-of-hospital sudden cardiac arrest (OHSCA) frequently occurs in sport-related acute myocardial infarction (AMI), contemporary clinical and coronary angiography (CA) findings remains poorly described. In a large retrospective study at a French regional scale, we aimed to investigate clinical and CA characteristics of patients who experienced OHSCA in sport-related AMI. From the RICO database, a French regional AMI survey, we retrospectively analysed the consecutive patients admitted in cardiology intensive care unit of a single university hospital from January 2011 to January 2018 for sport-related AMI and who underwent CA ( n = 100). Data from patients with OHSCA (OHSCA +) were compared with patients without OHSCA (OHSCA -). Among the study population, 20% had OHSCA. Main characteristics are presented in Table 1 (Median (IQR) or %). AMI patients with OHSCA were 6 y older, and were characterized by a higher rate of culprit lesion involving LAD, and had much poorer hospital outcome. CAD extent and proximal distribution of lesions showed a trend toward a more severe profile. Larger studies are needed to confirm our findings.
