title: Wellens syndrome caused by spasm of the proximal left anterior descending coronary artery.
abstract: Electrocardiographic characteristics of Wellens syndrome (WS) consist of deeply inverted T waves or biphasic T waves in anterior precordial leads. Studies have shown that patients with WS have critical stenosis or complete obstruction of the proximal left anterior descending coronary artery (LAD) and high risk for the development of extensive anterior myocardial infarction. Here, we reported a case presenting with WS and with a small plaque in the proximal LAD and slow flow in the LAD other than significant stenosis of the proximal LAD detected by coronary angiography. The mechanisms for WS of our case are discussed.
