PURPOSE: We sought to electrocardiographically distinguish ST-segment elevation (STE)-acute myocardial infarction (AMI) caused by occlusion of the first diagonal branch (D1) from STE-AMI caused by occlusion of the left anterior descending coronary artery (LAD). METHODS: We examined 28 patients with STE-AMI caused by D1 occlusion (G-D) and 342 with STE-AMI caused by LAD occlusion (G-L). RESULTS: G-D had a higher prevalence of STE > or = 0.5 mm in each of leads I and aVL and a lower prevalence of STE > or = 1 mm in each of leads V(1) through V(6) than G-L. The prevalence of STE > or = 0.5 mm in lead aVL without STE > or = 1 mm in lead V(1) was higher in G-D (82.1%) than in G-L (9.4%, P < .01). CONCLUSION: ST-segment elevation > or = 0.5 mm in lead aVL without STE > or = 1 mm in lead V(1) may be useful to distinguish STE-AMI caused by occlusion of the D1 from STE-AMI caused by occlusion of the LAD. |
