On the basis of the overall experience, the provocation of coronary artery spasm with ergonovine is thought to be a highly sensitive and specific test for coronary artery spasm in Prinzmetal's variant angina. In spite of occasional complications, in experienced hands the procedure is considered to be safe. The challenge remains to determine the value of this and other provocative interventions in assessing the role of spasm in other aspects of ischemic heart disease, particularly in patients with critical atherosclerotic lesions.
基于总体经验，麦角新碱激发冠状动脉痉挛被认为是诊断普林兹金属变异型心绞痛中冠状动脉痉挛的一项高度敏感且特异的检查。尽管偶尔会有并发症，但在经验丰富的医生操作下，该检查被认为是安全的。在评估痉挛在缺血性心脏病其他方面的作用，尤其是在有严重动脉粥样硬化病变的患者中，确定这项及其他激发性干预措施的价值仍是一项挑战。
