A Case of Wellens' Syndrome.

This is a clinical case of a 43-year-old male with a past medical history notable for tobacco use disorder who presented to the emergency department for evaluation of typical chest pain. ECG was consistent with Wellens' syndrome with deeply inverted T waves in the anteroseptal leads. Coronary angiography confirmed a proximal left anterior descending coronary artery lesion, alongside other areas of coronary artery disease, and the patient was treated with surgical revascularization.
