- Abstract
Background: Risk stratification for patients with acute myocardial infarction (AMI) and prediction of coronary artery disease severity (CAD) add a valuable benefit to the management and prognosis. We aimed to evaluate the relationship between P wave peak time (PWPT) on surface electrocardiography and Gensini score (GS) of coronary atherosclerotic lesions in AMI patients. Methods: A total of 76 patients presented with AMI were enrolled and were divided according to GS into two groups; GS <30 & GS ≥ 30. PWPT was obtained at both admission ECG and after 60 minutes from intervention and was compared between groups. Results: The mean age of our patients was 53.18 ± 9.95 years, 77.6 % were males and 22.4 % were females. Significant prolongation of PWPT duration was observed on admission ECG at GS ≥ 30 (65.51±5.61 ms) vs (57.04 ± 4.33ms) at GS <30, p<0.001. Wh ile after 60 min from reperfusion, the delta change at PWPT has significantly reduced at severe CAD group with NSTEMI rather than STEMI cases. PWPT at cut off value > 60 ms with (AUC 0.859; 95% CI 0.741-0.976; p < 0.001; sensitivity 70.5%, specificity 85.7%) was found as a good predictor of CAD severity in NSTEMI cases. Conclusion: PWPT is associated with the severity and complexity of CAD in patients with AMI & can be used as a simple, non-invasive tool adding in patient risk stratification.
