冠脉内镜能详细观察过脉腔内病变,对确定急性心肌梗塞的病因、治疗方案以及判断疗效均具有重要意义。本文对22例急性心肌梗塞急性期(发病8小时内)患者进行了冠脉内镜检查,发现结果如下。22例中有血栓者21例(95%),血栓的性状以红色血栓和混合血栓为多;不稳定型心绞痛患者白色血栓占多数,而陈旧性心肌梗塞和稳定型心绞痛患者几乎没有发现血栓。其中粥样斑块脱落、溃疡、内膜翻转等内膜损害者10例(45%);黄色粥样斑块11例(50%),较多见,由于内膜损害和黄色粥样斑块包埋在血栓中,故实际上可能更多些。因富含胆固醇等脂类、有薄层纤维帽的粥样斑块容易破裂,故易使血小板粘附、聚集并激活凝血系统,而导致血栓形成,从 Coronary endoscopy can be observed in detail the intraluminal lesions, the determination of the cause of acute myocardial infarction, treatment options and to determine the efficacy are of great significance. In this paper, 22 patients with acute myocardial infarction in the acute phase (within 8 hours of onset) underwent coronary endoscopy and found the following results. Twenty-two of the 22 patients (95%) had thrombus, the thrombus was characterized by more red blood clots and mixed thrombi, and the white blood clot was the most common in patients with unstable angina, while there was almost no thrombosis in patients with old myocardial infarction and stable angina. Among them, 10 cases (45%) had atherosclerotic plaque loss, ulceration, endometrial overturning and so on, and 11 cases (50%) of yellow atherosclerotic plaques were more common. Due to intimal lesion and yellow plaque Embedding in the thrombus, so in fact may be more. Because of cholesterol-rich lipids, thin-cap capsular plaque prone to rupture, it is easy to make platelet adhesion, aggregation and activation of the coagulation system, which led to thrombosis, from
