Acute Thrombotic Occlusion of proximal Left Anterior Descending Artery without ST-elevation (de Winter sign) in Electrocardiogram: A Case Report
ST-elevation in precordial leads is diagnostic for acute transmural myocardial infarction (MI) related to acute occlusion of left anterior descending artery (LAD).
In this case report, a 54-year-old man was admitted to the emergency department (ED) due to chest pain. ST-depression with tall T waves in precordial leads was detected in surface electrocardiogram (ECG). Angiography showed acute total occlusion of proximal LAD and ad hoc percutaneous coronary intervention (PCI) was performed successfully.
This case highlights that total occlusion of LAD may present without typical ST-elevation pattern in ECG.
