The general information, case data and pathological changes of 15 cases were collected to find the relationship between sexual activity and sudden death.ResultsThe ratio of male to female was 1.5∶1. The average age of males was 50.1 years and that of females was 35.0 years. Coronary artery diseases and brain diseases accounted for most of the cases （12/15）.
