Coronary spasm is an important and often overlooked etiology of chest pain. Although coronary spasm, or Prinzmetal's angina, has been thought of as benign, contemporary studies have shown serious associated adverse outcomes, including acute coronary syndrome, arrhythmia, and death. Definitive diagnosis of coronary spasm can at times be difficult, given the transience of symptoms. Numerous agents have been historically described for provocative testing. We provide a review of published data for the role of provocation testing in the diagnosis of coronary spasm.
冠状动脉痉挛是胸痛的一个重要且常被忽视的病因。虽然冠状动脉痉挛，或变异型心绞痛，被认为是良性的，但当代研究表明其与严重的不良后果相关，包括急性冠状动脉综合征、心律失常和死亡。鉴于症状的短暂性，有时冠状动脉痉挛的明确诊断较为困难。历史上曾有多种药物被用于激发试验。我们回顾了已发表的数据，以评估激发试验在冠状动脉痉挛诊断中的作用。
