Sudden cardiac arrests (SCA) and sudden deaths (SCD) are believed to account for a large proportion of due cardiovascular causes. The purpose this study is provide comprehensive information on the epidemiology SCAs SCDs after acute coronary syndrome.The incidence SCA (including SCDs) was studied retrospectively among 10,316 consecutive patients undergoing invasive evaluation syndrome (ACS) between 2007 2018 at Tays Heart Hospital (sole provider specialized care catchment area over 0.5 million residents). Baseline follow-up collected by combining from hospital's electronic health records, death certificate data, full-disclosure review written patient records accounts circumstances leading death.During 12 years follow-up, cumulative 9.8% (0.8% annually) that 5.4% (0.5% annually). Cumulative in with ST-elevation myocardial infarction, non-ST-elevation infarction unstable angina pectoris were: 11.9%,10.2% 5.7% years. accounted 30.5% (n = 528/1,732) all vast majority (95.6%) occurred without implantable cardioverter defibrillator (ICD) devices or no recurrent hospitalizations artery disease (89.1%).SCAs less than third causes previous ACS. Incidence highest STEMI NSTEMI patients. After hospital discharge, most happen
