本文回顾了5例成功经皮冠状动脉成形术后出现冠状动脉痉挛的患者的临床过程。所有患者在血流动力学不明显（< 50%内径变窄）梗阻时均出现痉挛。4例患者对钙通道拮抗剂和硝酸盐治疗无效，随后发生复发性狭窄。1例患者在血管成形术后2小时和冠状动脉搭桥手术后1天死亡。血管成形术部位的病理研究显示新的动脉硬化性疾病。冠状动脉痉挛可能发生在冠状动脉成形术后的愈合期间，应与固定梗阻区分开来。
The clinical course of 5 patients manifesting coronary artery spasm at the site of previous successful percutaneous coronary angioplasty is reviewed. All patients showed this spasm on hemodynamically insignificant (< 50% diameter narrowing) obstruction. Four patients did not respond to therapy with Ca channel antagonists and nitrates and subsequently developed recurrent stenosis. One patient died 2 mo. after angioplasty and 1 day after coronary bypass surgery. Pathologic study at the site of angioplasty revealed new artherosclerotic disease. Coronary spasm may occur during the healing period after coronary angioplasty and should be distinguished from fixed obstruction.
