Simultaneous Thrombotic Involvement of LAD and RCA in Combined ST-segment Elevation Myocardial Infarction: A Rare Clinical Entity

Simultaneous acute thromboses in both the left and right coronary arteries (RCAs) are uncommon.A 39-year-old male presented with chest pain and was admitted to the hospital.Electrocardiography (ECG) revealed ST-segment elevation in both the inferior and anterior leads.Due to the presence of ST-segment elevation myocardial infarction, emergency coronary angiography was performed.The angiogram demonstrated a complete occlusion in the proximal left anterior descending artery and a critical thrombotic lesion in the RCA.Both lesions were treated with stent placement.Acute coronary syndromes can present with varying ECG patterns, and simultaneous ST-segment elevations in the anterior and inferior leads are rarely observed.This report describes a case of combined acute coronary syndrome.
