Abstract
- Variant angina is a syndrome of cyclical chest pain at rest caused by vasospasm and associated with ST-segment elevation. Most of these cases are induced by the provocation with ergonovine or acetylcholine, and mechanical irritation of coronary artery by catheter, but spontaneous migrating spasm in right coronary artery is very rare. We report a fifty one year old male patient presenting as a variant angina due to spontaneous migrating spasm in right coronary artery during diagnostic coronary angiogram. The spasm was relieved spontaneously or by the administration of intracoronary nitroglycerin. No chest pain was documented after medication with calcium-channel blocker and nitrates on 6 month clinical follow-up. This paper presents our experience with a patient presenting with migrating coronay vasospasm of right coronary artery.
