Angiographic contrast material is generally considered a vasodilator, although in vitro experiments have documented a spasmogenic effect. In this report we describe a patient with exercise and rest angina who developed spasm of the right coronary artery immediately following left ventricular angiography. The patient was treated successfully with calcium channel blockers. This is the first reported case of left ventricular angiography-induced coronary artery spasm.
血管造影剂通常被认为是一种血管扩张剂,尽管体外实验已证明其有致痉挛作用。在本报告中,我们描述了一名患有运动性和静息性心绞痛的患者,其在左心室血管造影后立即出现右冠状动脉痉挛。该患者用钙通道阻滞剂治疗成功。这是首例报告的左心室血管造影诱发冠状动脉痉挛的病例。
