ABSTRACT
<p><b>OBJECTIVE</b>To assess the value of Tpeak-end interval (Tpe) in predicting myocardial infarction (MI).</p><p><b>METHODS</b>Tpe and Tpeak-end internal after correcting the heart rate (TpeRR) were measured and analyzed in 234 MI patients, who were followed-up for an average of 32 ± 10 months.</p><p><b>RESULTS</b>Clinical events occurred in 45 (19.2%) patients at the end TpeRR of the follow-up. Tpe and of the patients with clinical events were significantly higher than those in patients without the clinical events (P < 0.001). The incidence of clinical events in patients with Tpe > 140 ms were significantly higher than that in patients with Tpe ≤ 140 ms by Kaplan-Meier analysis (P < 0.001). With clinical event as the end point, the proportional hazards rate was 2.48 in univariate COX analysis (P < 0.01). After controlling for risk factors, the hazards rate was 2.66 by multvariate COX regression (P < 0.01).</p><p><b>CONCLUSION</b>Tpe is positively correlated to the prognosis of MI and serves as an new index for predicting the clinical events in MI patients.</p>
