目的探讨冠状动脉瘤样扩张并发急性心肌梗死病人的临床特征及发病机制。方法回顾性分析9例冠状动脉瘤样扩张并发急性心肌梗死病人的临床资料。结果9例均为男性,6例为右冠状动脉病变,占66.67%(6/9)。结论冠状动脉瘤样扩张发生急性心肌梗死,多见于男性,常累及右冠状动脉。发病机制可能与冠状动脉瘤样扩张处血管内膜的病理性改变、局部血流动力学异常、血栓形成、冠脉痉挛等因素有关。
Objective To investigate the clinical features and pathogenesis of patients with coronary aneurysmal dilatation complicated with acute myocardial infarction. Methods The clinical data of 9 patients with coronary aneurysmal aneurysm complicated with acute myocardial infarction were retrospectively analyzed. Results 9 cases were male, 6 cases of right coronary artery lesions, accounting for 66.67% (6/9). Conclusion Coronary aneurysm-like dilatation occurs in acute myocardial infarction, more common in men, often involving the right coronary artery. Pathogenesis may be associated with coronary artery aneurysm-like vascular endometrial pathological changes, abnormal hemodynamic, thrombosis, coronary spasm and other factors.
