目的 了解心电图正常的冠心病心绞痛患者冠状动脉造影特点 ,以提高临床诊断水平。方法 对 116例住院病人进行冠脉造影并对结果进行分析。结果 冠脉造影显示单支病变 40例 ( 44 .9% ) ,其中轻度狭窄 3 3例 ( 83 .5 % ) ;2～ 3支病变49例 ( 5 5 .1% ) ,共中左主干病变 2例 ;多支病变以前降支和右冠多见 ,有血管狭窄相对应部位 41例 ( 83 .7% )。结论 心电图正常的冠心病心绞痛患者 ,其 2～ 3支病变与血管狭窄部位相互对应相关 ;单支病变与血管狭窄程度较轻、侧支循环较好有关
Objective To understand the characteristics of coronary angiography in patients with normal electrocardiogram of coronary heart disease and angina pectoris to improve the clinical diagnosis. Methods One hundred and sixteen inpatients underwent coronary angiography and the results were analyzed. Results Coronary angiography showed that 40 cases (44.9%) had single vessel disease, including 33 cases (83.5%) with mild stenosis, 49 cases (23.5%) with 2 ~ 3 vessels, Lesions in 2 cases; multivessel lesions were more common in the anterior descending branch and the right coronary artery, with 41 (83.7%) corresponding sites of vascular stenosis. Conclusions Patients with normal electrocardiogram of coronary heart disease and angina pectoris have 2 to 3 lesions and vascular stenosis corresponding to each other; single vessel lesion with less stenosis, collateral circulation is better
