摘　　要：本文将128例心肌梗塞尸检结合临床作了对比分析,其中心肌再梗塞组76例(59.4%),其他52例作为对照组。心肌再梗塞病理形态的相对特点是冠状动脉各大主支粥样硬化(AS)均较对照组重,冠脉血栓形成也较对照组多。心肌再梗塞后的并发症除心脏破裂外,均较对照组检出率为高。Seventy-six autopsied cases of myocardial reinfarction were studied with 52 cases of primary myocardial infarction as control group. The prevalence of myocardial reinfarction was 59.4% in128 autopsied cases of myocardial infarction. In cases of myocardial reinfarction, the incidence of coronary artery stenosis >50% (degree Ⅲ), especially in the main branch of left coronary artery, (80.5%, vs. 19.5% in control); the incidence of coronary thrombosis (29.7% vs.18.8%), aneurysm (63.3% vs. 36.7%) and severe arrhythmia (84.0% vs. 16.0%) were higher than those in controls, however, the incidence of sudden death (35.7% vs. 64.3%) and cardiac rupture were lower (21.7% vs. 78.3%). Myocardial reinfarction is not only an extension of myocardial infarction size, but also causes severe damage of myocardial function, it is one of the important causes of death.
