作者测量了78例死于急性心肌梗塞(AMI)患者梗塞大小,观察梗塞大小与死亡方式、死亡距梗塞时间及有无冠脉血栓的关系.尸检病例选自美国心肺血研究所病理部门.将心脏横切成1cm厚薄片,以透明塑料片描绘心内、外膜及心肌梗死边缘.测量梗塞与非梗塞面积及每一切片重量.梗塞大小以占左室总重量之%表示之.78例从AMI发病至死亡的时间平均为12±13天.死亡原因有:心源性休克16例(21%),心律失常31例(40%),心脏破裂24例(31%),其它7例
The authors measured infarct size in 78 patients who died of acute myocardial infarction (AMI) and observed the relationship between the infarct size and the type of death, the time to death from infarction, and the presence or absence of coronary artery thrombosis. The autopsy cases were from the American Heart Association Laboratory for Cardiopulmonary Research Heart cross-cut into 1cm thick slices, with transparent plastic film depicting the heart, adventitia and myocardial infarction edge. Infarct and non infarct size measurement and weight of each section. Infarct size to account for the total left ventricular% of the 78 cases The mean time from onset of AMI to death was 12 ± 13 days.The causes of death were: cardiogenic shock in 16 cases (21%), arrhythmia in 31 cases (40%), cardiac rupture in 24 cases (31%) and other cases in 7
