Abstract

BACKGROUND:: EKG Tpeak–Tend (Tp–Te) interval, an index of transmural dispersion of myocardial repolarization, is gaining interest as possible cardiovascular prognostic variable. Evidence that this is the case in the general population is scanty, however. This was tested in the Pressioni Arteriose Monitorate E Loro Associazioni population. METHODS AND RESULTS:: EKG, echocardiographic, office, home and ambulatory (24-h) blood pressure (BP), metabolic and laboratory data were assessed. Cardiovascular and all-cause mortality were evaluated over a mean follow-up of 16 years. Repetition of all measurements after 10 years allowed to evaluate also the risk of developing office and out-of-office hypertension and echocardiographic left ventricular hypertrophy. At baseline, Tp–Te adjusted for confounders (c) showed a significant correlation with office, home and 24-h blood pressure but not with left ventricular mass. The cTp–Te value predicted the risk of cardiovascular and all-cause mortality before and after adjustment for demographic and clinical variables, the increase being 31 and 13% for 1-SD cTp–Te increase, respectively (P?
