N2 - Data on 1,281 patients from the Bilitch impIantabje cardioverter defibrillator (ICD) registry were reviewed to evaluate ICD patient characteristics and survival, and the impact of ICD shock occurrence on outcome. The mean ejection fraction was 34.3%; 78% had coronary disease, 471 patients had at least one shock thought to be appropriate, and 231 patients died. Causes of death included: arrhythmic (41%), nonarrhythmic cardiac (37%), and noncardiac (22%). Cumulative survival from all‐cause mortality at 1, 3, and 5 years was 89%, 76%, and 64%; survival from all‐cause cardiac death was 93%, 90%, and 76%; survival from arrhythmic death was 96%, 92%, and 87%. Patients who had received a shock had a trend towards a worse long‐term prognosis. Shock patients also had a small increase in the prevalence of coronary disease and a somewhat lower ejection fraction than the remainder of the population.
