Atypical high-risk presentation of the de Winter electrocardiographic pattern
Keywords:
acute coronary syndrome, left coronary artery, non-ST elevated myocardial infarction, unstable anginaAbstract
Introduction: The de Winter electrocardiographic pattern, described in 2008, is associated with proximal occlusion of the left anterior descending artery and is considered a high-risk equivalent of non-ST-segment elevation acute coronary syndrome. It is characterized by upsloping ST-segment depression in the precordial leads (V1–V6), along with tall and symmetrical T waves.
Objective: To describe the electrocardiographic features of this pattern, emphasizing its diagnostic recognition as a high-risk presentation.
Case report: We present the case of a 55-year-old male patient with typical angina whose electrocardiogram showed J-point depression in leads V3–V5, hyperacute T waves, and ST elevation in lead aVR. Coronary angiography revealed severe stenosis of the left anterior descending artery, successfully treated with stent angioplasty.
Conclusions: The de Winter pattern is an atypical electrocardiographic finding indicative of proximal left anterior descending artery occlusion. It constitutes a high-risk presentation that requires early recognition to enable timely reperfusion, even in the absence of classic ST-segment elevation.
