RESUMO
A 65-year-old male presented to the hospital with chest pain associated with recurrent syncope. He had a history of coronary artery disease and a long-standing history of smoking. While he was hospitalized, he had an episode of chest pain during which he was found to have transient ST segment elevation in the inferior leads. He was also noted to have a brief cardiac tachyarrhythmia. Coronary arteriography revealed vasospasm of the left anterior descending artery and right coronary artery, which were relieved to a significant extent after administration of intracoronary nitroglycerin. Subsequent angiograms and fractional flow reserve studies, demonstrated underlying non-obstructive coronary artery disease at the sites of spasm. No percutaneous coronary intervention was pursued. The patient was started on a calcium channel blocker on dismissal from the hospital. Upon follow up several months later, he remained free of symptoms that brought him to the hospital.
