急性下壁心肌梗塞并右心室梗塞的冠脉病变特点

Coronary Angiographic Fetures of Patints with Acute Infarction and Right Ventricular Myocardial Infarction

目的 了解下壁急性心肌梗塞 (AMI)并右心室梗塞 (RVMI)的冠脉病变特点。方法 对 43例 (其中 16例下壁AMI并RVMI患者的冠脉造影资料进行分析。结果 心电图提示下壁AMI并RVMI改变 16例 ,梗塞相关动脉 (IRA)为右冠脉 15例 (93 7% ) ,阻塞右冠脉近段 13例 (81 2 % ) ,中段 2例 (12 5 % ) ,均为右冠脉优势型。回旋支阻塞 1例(6 2 % ) ,且呈左冠脉优势型。结论 下壁AMI并RVMI的血管病变部位多见于优势型右冠脉的近段和中段。

Objective To investigate the coronary angiographic feature of patients with acute infarction and rigft ventyicular myocardial infarction(RVMI). Methods The coronary angiographic date in 43 patints with acute infarction myocardial infarction (16 of those patients presented with RVMI) were analysed. Results The infarction related artery (IRA) in 15 of 16 patients with RVMI was the right coronary artery. In those patients there were 13 cases (81.2%) with oculusion of proximal segment of right coronary artery and 2 cases (12.5%) with occulsion of middle segment. The coronary arteries of all those 15 paients were right predominant. One cases (6.28%) with occulsion of left circumflex artery had a left predominant coronary artery. Conclusion The coronary lesion of patients with both inferior and RVMI are coronary seen at the proximal and middle segement of right predominant coronary artery.
