BACKGROUND/AIMS: An upright T-wave in lead aVR (aVRT) has recently been reported to be associated with @entity65 and mortality among the general population and @entity1 with prior @entity65 ( @entity3257 ). However, evidence for the predictive ability of aVRT in @entity1 with @entity740 is lacking. Therefore, a hospital-based, prospective, cohort study was conducted to evaluate the predictive ability of an upright aVRT for the short-term prognosis in incident hemodialysis @entity1 . METHODS: Among 208 @entity1 who started maintenance hemodialysis, 79 with preexisting @entity3257 ( @entity3257 cohort) and 129 with no history of @entity3257 ( @entity3257 ), were studied. An upright and non-upright aVRT were defined as a wave with a positive deflection in amplitude of >= 0 mV and a negative deflection in amplitude of <0 mV, respectively. The endpoint was all-cause @entity204 . RESULTS: Overall, the prevalence of an upright aVRT was 22.6% at baseline. During the mean follow-up period of 2.1    1.0 years, 33 @entity204 occurred. Cumulative survival rates at 3 years after starting dialysis in @entity1 with an upright and non-upright aVRT were 50.0 and 80.7%, respectively, in the @entity3257 cohort and 92.0 and 91.3%, respectively, in the @entity3257 . In the @entity3257 cohort, multivariate Cox regression analysis showed that an upright aVRT was an independent predictor of @entity204 after adjusting for confounding variables. CONCLUSION: Among Japanese hemodialysis @entity1 at high risk for @entity3257 , an upright aVRT seems to be useful for predicting @entity204 .
