The simultaneous occurrences of spontaneous spasm and catheter-induced spasm during coronary angiography were obtained in 3 patients. Catheter-induced spasm was seen in the right coronary artery in 3 patients: 1 patient had spontaneous spasm in the distal right coronary artery and 2 patients had spontaneous spasm in the proximal left anterior descending coronary artery. These findings suggest that patients with variant angina may be susceptible to mechanical induction of spasm.
3例患者在冠状动脉造影期间同时出现自发性痉挛和导管诱发痉挛。3例患者右冠状动脉出现导管诱发痉挛：1例患者右冠状动脉远端出现自发性痉挛，2例患者左冠状动脉前降支近端出现自发性痉挛。这些发现提示变异型心绞痛患者可能易受机械性诱发痉挛影响。
