Brief summary
Vasospastic angina (VSA) is caused by brief spasms of the main coronary artery and its major branches, resulting in varying degrees of luminal occlusion. Although vasodilator therapy is widely used and significantly alleviates VSA symptoms, it has not led to notable improvements in the prognosis of patients with VSA. Recent studies have suggested that inflammation plays a crucial role in VSA. This study aimed to evaluate the potential effectiveness of immunomodulatory therapy for improving patient prognosis.

Eligibility
Inclusion criteria
(1) Transient total or subtotal occlusion of the coronary artery (contraction \>90%) observed either spontaneously or in response to irritant stimulation (typically acetylcholine, ergot, or hyperventilation); (2) Presence or absence of ischemic electrocardiogram changes during episodes; (3) Nitrate-responsive angina during spontaneous episode: rest angina and/or marked diurnal variation in exercise tolerance and/or episodes precipitated by hyperventilation and/or suppression of episodes by calcium channel blockers.
Exclusion criteria
(1) age 15 years or older; and (2) suspected VSA with chest pain and evidence of coronary spasm, or VSA diagnosed intraoperatively or at discharge. The following
