Wellens syndrome is an electrocardiogram (ECG) pattern associated with critical stenosis of the proximal left anterior descending (LAD) artery. In patients with Wellens syndrome, characteristic biphasic or inverted T waves are seen on ECG. This case report presents a 48-year-old male admitted for chest pain and shortness of breath who was found to have a Wellens syndrome ECG pattern. Oddly, cardiac catheterization revealed multi-vessel coronary artery disease, and critical proximal LAD artery stenosis was not appreciated. Ultimately, the patient was treated with coronary artery bypass graft (CABG) surgery and later discharged in stable condition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
