Stressful events as a trigger of sudden death: a study of 43 medico-legal autopsy cases.
The reports relating emotional stress to sudden death are largely anecdotal. In addition to experimental and electrophysiological studies, an opportunity for a better understanding of possible stress-related sudden death (SSD) may be provided by medicolegal autopsies. The goal of our autopsy study was to analyze cardiovascular pathologic findings in cases of SSD and if possible identify mechanisms by which the stressful event (SE) could be the cause. Forty three cases were studied (29 males and 14 females). In all cases, the SE and the death were witnessed. The age range was 22 to 90 years in males (mean, 52) and 30 to 92 years in females (mean, 64). Death occurred in all cases without premonitory symptoms. In 20 cases, death occurred during the SE and in the other 23 cases occurred within 2 h of the event. SE included fear, 15 cases; altercation, 21 cases; sexual activity, 3 cases; police questioning or arrest, 4 cases. According to police reports, in 40 cases (90%), the victims had no previous clinical history of cardiovascular disease. At autopsy, the heart weight in males ranged from 255 to 1000 g with a mean of 517 g and in females the range was 250-700 g with a mean of 417 g. In only 3 cases, gross and microscopic examination of the heart was normal. In 2 of the remaining 40 cases the subjects died of subarachnoid hemorrhage. In 38 cases, a cardiac cause of death was found as follows: coronary heart disease, 27 cases; cardiomyopathy, 6 cases; aortic valvular stenosis, 2 cases and right ventricular dysplasia, 3 cases. A coronary artery thrombosis was found in 8 cases of sudden coronary death. Post myocardial infarction fibrosis was present in 25 cases (92%) of sudden coronary death. In conclusion, it appears from our autopsy study that SSD occurs primarily in those individuals with severe heart disease, especially coronary heart disease.
