摘要

冠状动脉痉挛（CAS）是一种未被充分认识的心力衰竭原因，即使在没有阻塞性冠状动脉疾病的情况下。我们报告三例心力衰竭，其中CAS被确定为关键病因。所有患者均表现出非阻塞性冠状动脉心力衰竭症状，CAS激发试验证实心外膜痉挛。在两个病例中，心脏磁共振成像显示与cas相关损伤一致的缺血模式。钙通道阻滞剂有效地稳定与心力衰竭相关的体征和症状。该系列强调了CAS作为心力衰竭进展的一个因素，并强调了激发试验和早期定制治疗对改善结果的重要性。

Coronary Artery Spasm as a Contributor to Heart Failure: Lessons from Three Cases.

Coronary artery spasm (CAS) is an underrecognized cause of heart failure, even in the absence of obstructive coronary artery disease. We report three cases of heart failure in which CAS was identified as the critical etiology. All patients exhibited symptoms of heart failure with nonobstructive coronary arteries, and CAS provocation testing confirmed epicardial spasm. In two cases, cardiac magnetic resonance imaging revealed ischemic patterns consistent with CAS-related injuries. Calcium channel blockers effectively stabilize the signs and symptoms related to heart failure. This series highlights CAS as a contributor to heart failure progression and emphasizes the importance of provocation testing and early tailored therapy for improving outcomes.
