OR11. Association between T peak-T end interval and mortality in patient with complex coronary lesion scheduled for Coronary Artery Bypass Graft procedure

Abstract

Abstract Aim Patient with complex coronary lesion face a mortality risk caused by sudden cardiac death (SCD). The Tpeak-Tend (TpTe) interval is a measure of dispersion of ventricular repolarization. Our aim is to investigate the relationship between the TpTe interval in patient’s resting 12-lead electrocardiogram (ECG) and the mortality incidence of patient waiting for Coronary Artery Bypass Graft (CABG) procedure. Methods and result Total of 175 patient scheduled for CABG procedure between January 2018 to December 2020. ECG was taken from medical record, interval of TpTe is calculated in V2 lead with tangent method ECG analysis. Association between variables analysed with Pearson chi-square test. Baseline characteristic showed age 58.7 ± 6.8 years old, syntax score 30.66 ± 4.0 and left ventricle ejection fraction 47.8% ±14.4. There is significant association between prolonged TpTe interval (>85 ms) and mortality incidence before CABG with odds ratio 3.821 (95% CI 1.727 – 8.454; p = 0.001). Conclusion TpTe interval is a feasible parameter that associate with the mortality in patient with complex coronary disease.
