急性心肌梗塞时心脏破裂发生率约10%(4～24%),次于心律障碍及心衰为占第三位的致死原因。多数系左室游离壁破裂。室中隔破裂仅1～2%,乳头肌断裂低于1%,此二者一般不难诊断。有时认为隐蔽性穿孔而心异管检查诊断为假性动脉瘤。至今对本病致死后果未予应有重视。 The incidence of heart rupture in acute myocardial infarction is about 10% (4 to 24%), which is second to heart rhythm and heart failure as the third leading cause of death. The majority of left ventricular free wall rupture. Ventricular septal rupture only 1 to 2%, papillary muscle rupture less than 1%, the two are generally not difficult to diagnose. Sometimes considered hidden perforation and cardiac catheterization diagnosis of pseudoaneurysm. So far the consequences of the death of this disease has not been given due attention.
