Chest pain with ST-T changes on electrocardiogram and localized stenosis on coronary angiography could be a coronary vasospasm

Coronary vasospasm is characterized by chest pain at rest with ST-T changes on electro cardiogram and coronary angiography showing virtually normal coronaries. The definitive diagnosis requires the stimulation of coronary vasospasm using provocative agents, which can be life threatening. We present a case where localized stenosis of proximal left anterior descending artery was observed on the coronary angiography, which disappeared on subsequent views, and hence, coronary stenting was deferred and patient responded well to medical management alone.
