Value of the Electrocardiogram in Localizing the Occlusion Site in the Left Anterior Descending Coronary Artery in Acute Anterior Myocardial Infarction

OBJECTIVES The study assessed the value of the electrocardiogram (ECG) as predictor of the left anterior descending coronary artery (LAD) occlusion site in relation to the first septal perforator (S1) and/or the first diagonal branch (D1) in patients with acute anterior myocardial infarction (AMI). BACKGROUND In anterior AMI, determination of the exact site of LAD occlusion is important because the more proximal the occlusion the less favorable the prognosis
