A case of multivessel variant angina after an open radical nephrectomy operation (RNO) is presented. A 52-year-old man was admitted to the coronary care unit with recurrent chest pain and dynamic ST-T wave changes on electrocardiogram early after an RNO. The first diagnosis of the clinical condition was non-ST segment elevation acute coronary syndrome. However, recurrent angina with ST segment elevation occurred after the standard medical therapy, which included beta-blockers. Emergency coronary angiography showed diffuse and multiple narrowing of all the three major coronary arteries during the chest pain, which was relieved by intracoronary nitroglycerine injection. Variant angina was suspected, and beta-blocker therapy was replaced with calcium channel blocker treatment. No angina attacks were observed during the clinical follow-up. Although a direct relationship between the type of surgery and variant angina was not established, coronary vasospasm after an RNO should be kept in mind, especially in the differential diagnosis of a patient with recurrent angina and dynamic ST-T changes on electrocardiogram. Although beta-blocker therapy is a first-line treatment for all acute coronary syndromes, it can be harmful in patients with variant angina and should be stopped immediately after verification of diagnosis.
本文介绍了一例开放性根治性肾切除术后出现多支血管变异型心绞痛的病例。一名52岁男性在根治性肾切除术后早期因反复胸痛和心电图动态ST-T波改变入住冠心病监护病房。临床情况的初步诊断为非ST段抬高型急性冠状动脉综合征。然而,在包括β受体阻滞剂在内的标准药物治疗后,出现了伴有ST段抬高的反复心绞痛。急诊冠状动脉造影显示,胸痛发作时所有三支主要冠状动脉弥漫性多发狭窄,冠状动脉内注射硝酸甘油后症状缓解。怀疑为变异型心绞痛,β受体阻滞剂治疗改为钙通道阻滞剂治疗。临床随访期间未观察到心绞痛发作。虽然手术类型与变异型心绞痛之间未建立直接关系,但根治性肾切除术后的冠状动脉痉挛应予以关注,尤其是在对反复心绞痛且心电图有动态ST-T改变的患者进行鉴别诊断时。尽管β受体阻滞剂治疗是所有急性冠状动脉综合征的一线治疗方法,但对变异型心绞痛患者可能有害,确诊后应立即停用。
