青年男性冠状动脉病临床与冠状动脉造影分析

Coronary angiographic characteristics of young men with coronary artery disease

目的 探讨青年男性 (<40岁 )心绞痛临床与冠状动脉造影 (CAG)的特点。方法 将90例青年男性心绞痛患者按心肌梗塞 (MI) (2 0例 )、典型心绞痛 (34例 )、不典型心绞痛 (36例 )分为三组并行 CAG。结果 有冠状动脉病变 (CAD)者 47例 (5 2 .2 % )。MI组 18例 (90 % ) ,典型组 2 2例(6 4.7% ) ,不典型组 7例 (19.4% )。三组之间 CAD检出率比较有显著性差异 ,MI组 >典型组 >不典型组。冠脉狭窄 <5 0 %轻度病变 13例 ,占 47例 CAD的 2 7.7%。结论 青年 MI的主要病因是冠状动脉粥样硬化。典型心绞痛对 CAD的诊断价值较大 ,<5 0 %轻度病变是青年 CAD的一种临床类型或亚型。

Objective To study the coronary angiographic(CAG) characteristics of young men with angina pectoris(AP).Methods 90 cases were divided into myocardial infarction(MI,20) group,typical angina pectoris(TAP,34) group and atypical angina pectoris(AAP,36) group,CAG were performed for all patients.Results The incidences of coronary artery diseases among 3 groups were significantly different and 90% in MI group,64.7% in TAP group and 27.7% in AAP group,respectively.Conclusion Coronary atherosclerosis is the major cause of MI in young men.TAP has important value for diagnosis of CAD and mild lesions less than 50% in stenotic severity are common in young CAD patients.
