Despite a recent epidemiological study reporting a lower incidence of sudden cardiac death (SCD) in China as compared with that in Western countries, the exact causes of SCD are still unknown. Using a uniform review protocol and diagnostic criteria, a retrospective autopsy study identified 553 cases of SCD in 14,487 consecutive autopsies from eight regions in China representing different geographic and population features. Their ages ranged from 18 to 80?years (median 43.0?years) with a ratio of 4.3/1.0 for male/female. Out-of-hospital deaths and unwitnessed cases accounted for 74.3 and 22.6?%, respectively. The main causes of death were coronary atherosclerotic disease (CAD 50.3?%), myocarditis (14.8?%), and hypertrophic cardiomyopathy (4.5?%), with unexplained sudden death accounting for 12.1?% of the cases. CAD had a proportion of 10.4?% in victims
