摘　　要：目的分析冠状动脉造影无明显狭窄病变而有冠状动脉迂曲的胸痛病人的临床特点。方法将102例冠状动脉造影无明显狭窄病变的胸痛病人分为冠状动脉迂曲组78例和无迂曲组24例,观察两组胸痛发作情况、临床用药效果、冠状动脉造影特点和心电图及运动试验的特点。结果与无迂曲组相比,冠状动脉迂曲组多为典型的劳累型心绞痛,β受体阻断药为主的抗心绞痛治疗常有效,静息心电图多为冠状T波,运动试验多阳性。结论冠状动脉无明显狭窄病变而有冠状动脉迂曲的病人可出现典型劳累型心绞痛、冠状T波、运动试验阳性、β受体阻断药为主的抗心绞痛治疗有效等表现,临床上酷似冠心病,冠状动脉造影对鉴别这类病人有特殊意义。Objectives To analyze the clinical characteristics in chest pain patients with coronary artery tortuosity without coronary stenosis defined by coronary angiography. Methods Of 102 cases in this study, 78 cases in tortuosity group and 24 cases in non-tortuosity group. All the patients received coronary angiography and rest electrocardiography （ECG）, and part of them did exercise test because of suspected angina. Results Most of the patients in coronary artery tortuosity group suffered stable angina （vs non-tortuosity group, P〈0.01 ） and had a good response to β-blockers. The rest ECG showed coronary T waves, and exercise test produced positive results more easily. Conclusions Many patients of coronary artery tortuosity without coronary stenosis may suffer from typical angina and to be diagnosed as coronary heart disease easily. Coronary angiography is necessary for identifying the chest pain patients from real coronary heart disease.
