Abstract
A clinicopathological study was made on a total of 6 cases of cardiac rupture following myocardial infarction, which was found among 50 cases of recent myocardial infarction with the incidence of 16%. Five out of 6 were women, age ranged from 68 to 88 with an average of 77 years old, and 5 cases showed a previous history of hypertension. In 3 cases both old and fresh myocardial infarctions were documented by electrocardiograms. Pathological examination showed the mixture of old scar or fibrosis and fresh myocardial infarction in all cases. Cardiac rupture occurred at the border of the old and fresh myocardial lesions presumed by increased strain at the junction area. Bizarre electrocardiogram at the time of cardiac rupture was shown in one of the cases, which was thought as extraordinarily rare.
