摘要
目的研究急性心肌梗死(AMI)时影响冠脉侧支循环(CCC)形成的因素。方法共入选142例就诊我院的首次AMI患者,均在AMI发作1 d内行冠状动脉造影术(CAG),依照Rentrop侧支循环分级,分为侧支循环良好组(良好组:侧支循环Ⅱ、Ⅲ级)和侧支循环不良组(不良组:侧支循环0、Ⅰ级),将两组患者的临床资料和冠脉造影资料进行对比分析。结果冠脉侧支循环形成与糖尿病呈负相关,与梗死前心绞痛病程(>3个月)及冠脉病变支数呈正相关,而与年龄、性别、吸烟史、血脂水平、高血压病等无关。结论梗死前心绞痛病程(>3个月)、冠脉病变支数是AMI患者形成侧支循环的有利因素,糖尿病不利于侧支循环形成。
AIM To study the factors influencing the formation of coronary collateral circulation （CCC） when acute myocardial infarction （AMI） occurs. METHODS One hundred and forty-seven AMI patients underwent coronary angiography （CAG） within 24 h after onset of AMI. Patients were divided into two groups （good and poor） according to the Rentrop collateral circulation. Patients in the good group had good collateral circulation （ grades II and III） and patients in the poor group had poor collateral circulation （grade 0, I）. Clinical data and results of coronary angiography were analyzed and compared between groups. RESULTS Formation of coronary collateral circulation was negatively correlated with diabetes and was positively correlated with the duration of pre-infarction angina （ 〉 3 months ） and numbers of diseased coronary vessels, regardless of age, gender, smoking, cholesterol, hypertension. CONCLUSION Duration of pre-infarction angina （ 〉 3 months ） and number of diseased coronary vessels are the factors conducive to the formation of collateral circulation. Diabetes is not conducive to the formation of collateral circulation in AMI patients.
