Abstract: Objective To explore the prognostic significance of T wave direction in lead aVR in patients with acute ST-segment elevation myocardial infarction (ASTEMI).Methods A total of 322 patiens with ASTEMI was examined.The patients were classified into 2 groups (T-wave positive,and T-wave non-positive) base on the direction of T wave in lead aVR.This study was ought to determine the association of T wave direction in lead aVR with the incidence rate of major adverse cardiac events (MACE) after discharge 2 years.Results After discharge 2 years,T-wave positivity patients had higher incidence of MACE than T-wave non-positive patients (P ＜ 0.05).Multivariate Cox proportional hazards regression analyses showed that age,and upright T wave in lead aVR were significantly associated with the primary end point.Conclusions T wave direction in lead aVR is a powerful prognostic marker for long-term prognosis.
