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.
两名患者均为65岁以上男性，既往无心肌梗死病史，突发胸痛。其中一名男性在第一天因心源性休克死亡，另一名在住院第四天死亡。每次尸检均发现透壁性心肌梗死伴出血，导致心脏破裂。在心肌梗死的坏死区域发现出血。每次心脏破裂均位于出血性梗死灶的中心。破裂呈撕裂状缝隙。梗死灶出血区域的愈合过程比贫血区域延迟得多。这两例病例提示出血性梗死可能是心脏破裂的危险因素之一。
