[Two cases of cardiac rupture after myocardial hemorrhagic infarct].

Two patients, both of whom were men over 65 years of age who had no history previous myocardial infarcts, had sudden chest pain. One of the men died due to cardiogenic shock on the first day, and the other died on the fourth hospital day. Each autopsy disclosed transmural myocardial infarct with hemorrhage, resulting in cardiac rupture. Hemorrhage was recognized in the necrotic area of the myocardial infarcts. Each cardiac rupture was found in the center of the hemorrhagic infarcts. The ruptures were tear-like slits. The healing process of the infarct was much more delayed in the hemorrhagic area than in the anemic area. These two cases suggest that hemorrhagic infarct may be one of the risk factors of cardiac ruptures.
