BACKGROUND: The interval between the peak and the end of the T wave (Tp-e interval) on 12-lead ECG is a measure of transmural dispersion of repolarization and may be related to malignant ventricular arrhythmias. The objective of this study was to investigate whether the Tp-e interval predicts in-hospital and long-term mortality in patients with ST-segment elevation myocardial infarction (STEMI) undergoing a primary percutaneous coronary intervention (pPCI). METHODS: This study included 488 consecutive patients with STEMI treated with pPCI. Electrocardiograms were obtained after pPCI and the Tp-e interval was measured in leads without ST-segment elevation. RESULTS: There were 46 (9.4%) deaths in the population, with a mean follow-up time of 21.1±10.2 months. The Tp-e interval was associated with not only in-hospital ventricular tachycardia/fibrillation, target vessel revascularization, and death but also long-term target vessel revascularization and death. Furthermore, the Tp-e interval measured using the tail method was found to be a significant predictor of long-term mortality in multivariable Cox analyses [odds ratio 1.018, 95% confidence interval (1.004-1.033)]. Findings were similar in the Tp-e interval and the heart rate-corrected Tp-e interval (cTp-e). CONCLUSION: Tp-e and cTp-e measured using the tail method were found to be predictors of both in-hospital and long-term mortality.
