[Death due to myocardial infarction in young patients: A study of 312 cases of sudden death]

Sudden cardiac death in young is seen as a dramatic phenomenon requiring knowledge of its impact. We aim to study the epidemiological characteristics of sudden cardiac ischemic death in young, and to discuss his involvement in the occurrence of death. We performed a retrospective cohort study using autopsy data from the department of forensic medicine of the University Hospital of Fattouma Bourguiba, Monastir-Tunisia. A review of all autopsies performed during 23 years was done. In each case, clinical information and circumstances of death were obtained. We have included all sudden death in persons aged between 1 year and 35 years for the male and from one year to 45 years for female. We collected 312 cases of sudden death during the studied period. The collected data were processed using SPSS 20. The significance level was set at 0.05. Thirty-two cases of cardiac ischemic sudden death have been collected. Myocardial infarction was the second cause of sudden death in young patients. There was a male predominance. The most affected subjects were aged between 25-45 years. The death occurred more frequently at rest. Coronary artery disease has been discovered in twenty-four cases (75%). The myocardial infarction occurred on healthy coronary arteries in eight cases. An anomalous course of coronary arteries, in particular myocardial bridging, was found in eight cases (25%). Toxicological screening was negative in all cases. Identifying epidemiological characteristics of sudden cardiac ischemic death in this population is important for guiding approaches to prevention that must be based on dietary hygienic measures and the control of cardiovascular risk factors.
