背景虽然对冠状动脉疾病的危险因素已有许多研究,而冠脉痉挛的病因至今还不甚明了。高胆固醇血症、糖尿病、高血压、吸烟、遗传均有导致冠心病的危险。而对血管痉挛性心绞痛的病因研究较少。本文介绍通过研究,对经冠脉造影证实的血管痉挛性心绞痛病人与冠脉造影正常的受检者的回顾性比较,检验冠状动脉痉挛的主要危险因素。方法将1975～1990年经冠状动脉造影符合其研究对象者351例,分成二组。1组(血管痉挛组)175 Background Although there have been many studies on the risk factors for coronary artery disease, the etiology of coronary artery spasm remains unclear. Hypercholesterolemia, diabetes, hypertension, smoking, genetic risk of coronary heart disease. The cause of angina spasmodic angina less. This article presents a retrospective comparison of subjects with normal coronary angiography confirmed by coronary angiography and the main risk factors for coronary artery spasm. Methods From 1975 to 1990 by coronary angiography consistent with its study of 351 cases, divided into two groups. Group 1 (vasospasm group) 175
