RESUMO
INTRODUCTION: Wellens Syndrome (WS) is a condition characterized by typical changes in ECG, which are biphasic T-wave inversions (less common) or symmetric and deeply inverted T waves (including 75%) in lead V2-V3 chest derivations. WS is considered important because it has not only diagnostic value but also prognostic value. CASE REPORT: A 52-year-old male patient without cardiovascular disease or risk factors was admitted to the emergency department (ED) suffering with chest pain and syncope, just after having been involved in a discussion at work. Chest pain was radiating to the left arm and was not precipitated by exertion. Shortness of breath was not accompanied by angina. The patient underwent cardiac catheterization at Department of Cardiology. Stents were positioned in both LADA and a severe lesion in the left main coronary artery. The patient was discharged two days following catheterization, due to no chest pain and hemodynamic instability during the hospitalization. The patient has approved the inform consent for to be used for this case report.
