De Winter electrocardiogram pattern evolving into Wellens electrocardiogram pattern in post-percutaneous coronary intervention therapy: a case report.

ABSTRACT:

Background

The de Winter electrocardiogram (ECG) pattern and Wellens ECG pattern are rare but critical ECG findings, often considered high-risk equivalents of ST-segment elevation myocardial infarction (STEMI) associated with proximal left anterior descending coronary artery (LAD) occlusion, necessitating urgent angiography and reperfusion. Limited literature documents cases where the de Winter ECG pattern transitions into the Wellens pattern following percutaneous coronary intervention (PCI).

Case summary

A 73-year-old man with a history of intermittent chest pain over 1 year presented with exacerbation lasting 3 h, leading to hospitalization for acute coronary syndrome (ACS). During chest pain, the ECG displayed the de Winter ECG pattern, prompting immediate emergency coro
