Electrocardiographic Wellens Pattern as an Indicator of Critical Proximal Left Anterior Descending Artery Stenosis: A Case Report
Abstract: Wellens syndrome is a pre-infarction electrocardiographic entity indicative of critical stenosis of the proximal left anterior descending (LAD) coronary artery. Early recognition is essential as delayed management may culminate in extensive anterior wall myocardial infarction. We report the case of a 41-year-old male who presented with retrosternal chest pain of five days? duration radiating to the left shoulder and associated with palpitations and breathlessness. Electrocardiography obtained during a pain-free interval demonstrated deep symmetrical T-wave inversions in leads V2?V5 consistent with Type B Wellens pattern. Cardiac biomarkers were positive. Echocardiography revealed regional wall motion abnormalities with left ventricular ejection fraction of 50%. Coronary angiography demonstrated critical proximal LAD stenosis (99%) with mid-LAD 80% stenosis. The patient underwent successful percutaneous coronary intervention with drug-eluting stent deployment achieving TIMI III flow and favorable recovery. This case emphasizes the importance of early recognition of Wellens syndrome and urgent revascularization to prevent impending extensive anterior wall myocardial infarction.
