Abstract
Objective: To assess late potential in patients with coronary artery disease (CAD). Subject and method: A descriptive, cross-sectional study, recording the signal averaged electrocardiogram on 162 patients with chronic CAD, treated at 108 Military Central Hospital from September 2016 to October 2018. Result: Most the patients (91.4%) were hospitalized because of chest pain. Male/female ratio ~ 4/1. The frequency of abnormal late potentials (positive) was 38.3%. The parameters in the VLPs group (+) were significantly different from those in the VLPs group (-): HFQRS and LAHF were higher (110.35 ± 16.45 and 41.08 ± 5.38ms) compared with (81.03ms) ± 9.49 and 29.71 ± 7.57ms); while RMS40 = 16.81 ± 3.96mcV was smaller than 29.26 ± 10.96mcV in VLPs group (-) (p<0.05). The frequency of late potentials (+) in the group with ventricular wall dyskinesia was 57.1%. Conclusion: VLPs (+) were found in 38.3% of patients with CAD. Factors that increased the risk of VLPs (+) include: Young age with CAD, height, myocardial ischemia site (wide, anterior wall, posterior wall) and reduced ejection fraction, ventricular wall dyskinesia.
