急性心肌梗塞早期,冠状动脉造影显示约90％穿壁性心肌梗塞的梗塞区冠状动脉完全阻塞。但随着时间的推移其完全阻塞发生率减低,且与冠状动脉自发性再通(Spontaneous reperfusion)有关。冠状动脉正常或无明显管腔狭窄的心肌梗塞报道较
Early in acute myocardial infarction, coronary angiography showed complete occlusion of the coronary arteries in approximately 90% of infarcted areas with transmyocardial infarction. However, its incidence of complete obstruction decreased over time and was associated with spontaneous reperfusion of the coronary arteries. Coronary artery with or without significant stenosis of myocardial infarction reported more
