Catheter-induced spasm has generally been considered to represent an iatrogenic phenomenon without important clinical significance. This report describes two patients who developed catheter-induced spasm in the proximal segment of the right coronary artery in separate studies performed in different laboratories by means of different catheter techniques. One of these patients developed right coronary spasm on three occasions and, in addition, developed catheter-induced spasm of the left main trunk during two different studies. These observations would add support to the hypothesis that a predisposition to coronary artery spasm may exist in certain individiuals. Catheter-induced spasm deserves attention, since it may provide a means of identifying spasm-prone individuals.
导管诱发的痉挛通常被认为是一种医源性现象，没有重要的临床意义。本报告描述了两名患者，他们在不同实验室采用不同导管技术进行的单独研究中，在右冠状动脉近端发生了导管诱发的痉挛。其中一名患者三次发生右冠状动脉痉挛，此外，在两项不同研究中还发生了左主干导管诱发的痉挛。这些观察结果将支持这样一种假设，即某些个体可能存在冠状动脉痉挛的易感性。导管诱发的痉挛值得关注，因为它可能提供一种识别易痉挛个体的方法。
