Abstract:
Objective To study the characteristics of infarct-related-artery (IRA) in acute high lateral wall myocardial infarction and to give clinical clue for deducing the location of coronary artery lesions. Methods Ninety-six patients with acute high lateral wall myocardial infarction (77 males, 19 females, mean age 57.3?10.7 years) were enrolled in the study. They all had infarction for the first time and were confirmed to have single vessel coronary artery disease by coronary angiography. The patients were divided into 3 groups according to the ECG changes at the onset of infarction. The first group (group A) was simple high lateral wall infartion (23 cases). The second one (group B) was high lateral with anterior wall infarction (58 cases, among them 27 cases with anteral-septal infarction and the other 31 with extensive anterior infarction). The third group (group C) was high lateral with lateral wall infarction (15 cases). Lesion characteristics of IRA were analyzed. Results The infarction-related lesions were mainly on left anterior descending arteries in group B (56/58), and on left circumflex in group C (13/15). But those in group A could be on either diagonal (12/23) or left circumflex (11/23). The difference of distribution of IRA among these groups was statistically significant (P
