Abstract：Objective To investigate the correlation between emergency coronary angiographies and electrocardiogram in the patients with acute myocardial infarction (AMI) and complete left bundle branch block (CLBBB).Methods Thirty-two patients with AMI and CLBBB received emergency coronary angiography were retrospectively and consecutively enrolled for analysis. Gensini score and sgarbossa score were calculated for each patient and used for correlation analysis.Result The number of patients with Killip class ≥2 and three-vessel coronary disease were 25 (78.1%) and 18 (56.3%), respectively. Among patients with new onset of LBBB, 16 patients had infarction related arteries (IRAs) with anterior descending branches, 4 patients had IRA with right coronary arteries. Among patients with previous history of LBBB, 6 patients had IRAs with anterior descending branches and 6 patients had IRA with right coronary arteries. The number of patients diagnosed as AMI with modified sgarbossa standard (n=26, 81.3%) was higher than those with sgarbossa standard (n=14, 43.8%) when use the cut-off of score≥3. There was no significant correlation of sgarbossa standard or modified sgarbossa standard with the three lesions, double branch lesions and single branch lesions assessed by coronary angiography. Gensini score was positively correlated with sgarbossa standard (r=0.889,P<0.05) and modified sgarbossa standard (r=0.905, P<0.05).Conclusion The IRAs with anterior descending branches and cardiac dysfunction were common in patients with AMI and CLBBB. Modified Sgarbossa criteria has important value in the diagnosis of the patients with AMI and CLBBB.
