From Wellens' syndrome to acute anterior myocardial infarction, what is required? Only time!

ABSTRACT

The hallmark of Wellens' syndrome is a distinct modification in the precordial T wave of the electrocardiogram (ECG), which usually indicates substantial stenosis of the proximal left anterior descending artery (LAD). Patients with Wellens' syndrome commonly do not exhibit any symptoms of chest pain. This current case report describes a male patient in his early 60s who presented with sporadic chest pain who was subsequently diagnosed with Wellens' syndrome-related electrocardiographic abnormalities. In the precordial leads V2-V5, an inverted symmetric T wave was visible on the asymptomatic ECG. The inverted symmetric T wave of the precordial lead V2-V5 reverted back to being upright when the chest pain started. A follow-up ECG performed before emergency surgery revealed ventricular premature beats and an increase of 0.1-0.5 mV in the ST segment of the precordial leads V1-V5. A drug-eluting stent was inserted after the patient's coronary angiography revealed proximal stenosis of the LAD. To prevent acute myocardial infarction, emergency physicians must identify the ECG signs of Wellens' syndrome and treat high-risk patients with revascularization as soon as feasible. Early recognition and proactive intervention are crucial, as they may help to alleviate adverse consequences.
