虽已证实家族史是冠状动脉病的一个重要危险因素,但仅有少数报告证实变异型心绞痛具有遗传性。本文报告兄弟俩由冠状动脉左前降支痉挛引起的变异型心绞痛。病例报告患者51岁,因清晨安静时发作心绞痛一周就诊。每日吸烟30支,入院时体检正常,血压118/62mmHg,脉搏70次/min,规则。安静时心电图正常,胸 X 线片正常。自发性心绞痛期间心电图显示胸前导联 ST 段抬高,继而发生室性心动过速。冠状动脉造影显示大动脉或分支均无明显狭窄,左室造影正常。静注麦角新碱0.15mg 后,心电图表现与导管插入前自发心绞痛期间改变相同,冠状动脉造影显示左前降支在前室间支和对角支远侧次全闭塞。病人
Although family history has been shown to be an important risk factor for coronary artery disease, only a few reports confirm that variant angina is hereditary. This article reports the variant angina pectoris caused by the left anterior descending coronary artery in both brothers. Case report 51-year-old patient, due to early morning angina pectoris attack a week treatment. 30 cigarettes a day, normal physical examination on admission, blood pressure 118 / 62mmHg, pulse 70 beats / min, rules. Quiet ECG, normal chest X-ray film. ECG during spontaneous angina showed ST-segment elevation in the lead of the chest followed by ventricular tachycardia. Coronary angiography showed no significant aortic stenosis or branches, normal left ventricular angiography. After intravenous administration of ergometrine 0.15 mg, the ECG showed the same changes during spontaneous angina pectoris prior to catheterization. Coronary angiography showed that the left anterior descending branch was occluded in the anterior chamber and distal branch of the diagonal. patient
