A young girl with vasospastic angina associated with mutation in endothelial nitric oxide synthase gene--a case report.

A 13-year-old girl was successfully recuperated from cardiopulmonary arrest shortly after running 80 m in a competition. The electrocardiogram, echocardiogram and 123I-MIBG myocardial scintigraphic imaging indicated myocardial ischemia in the anteroseptal wall of the left ventricle. Coronary angiography during the recovery phase revealed no stenotic lesions, and spasms of the left anterior descending artery and the left circumflex artery could be provoked by acetylcholine.
