title: Spontaneous coronary artery spasm documented in a young woman. A case report.
abstract: A 35-year-old woman with coronary risk factors presented with nonexertional atypical burning chest pain of 1 week's duration. A myocardial perfusion study with Tc-99m MIBI revealed a severe stress induced anteroseptal perfusion defect that completely reperfused on a subsequent resting Tc-99m MIBI study. Coronary angiography showed mild nonobstructive coronary artery disease. At the termination of the procedure, a spontaneous episode of burning chest pain occurred. Left main coronary artery reinjection of contrast revealed proximal diffuse left anterior descending coronary artery spasm. The patient was followed for 2 years with no further episodes of chest pain, while on calcium channel-blocker medication. The phenomenon of vasospastic angina and the role of myocardial perfusion scintigraphy is discussed.
