Abstract

Two cases of Prinzmetal's variant angina are presented in which coronary spasm was documented by electrocardiographic evidence obtained in the coronary care unit during provocative testing with ergonovine maleate after the arteriographic demonstration of anatomically normal coronary arteries. The rationale and risks of provocative testing for spasm in patients with chest pain and anatomically normal coronary arteries are reviewed. The advantages of performing provocative testing in the coronary care unit after arteriography rather than in the catheterization laboratory during coronary arteriography are discussed.

摘要

本文报告了2例变异型心绞痛病例，在冠状动脉造影显示冠状动脉解剖结构正常后，于冠心病监护病房使用马来酸麦角新碱进行激发试验，通过心电图证据记录到冠状动脉痉挛。回顾了对胸痛且冠状动脉解剖结构正常的患者进行痉挛激发试验的基本原理和风险。讨论了在冠状动脉造影后于冠心病监护病房而非在冠状动脉造影期间于导管室进行激发试验的优点。
