heart failure (HF), whose prevalence is steadily increasing, is associated with cardiovascular (CV) morbidity and mortality in not only the general population but also patients with end-stage renal disease (ESRD). However, the impact of diastolic dysfunction on the CV outcomes selleck has never been explored in incident dialysis patients with preserved systolic function. Methods: This prospective observational cohort study was undertaken to investigate the clinical consequence

of diastolic dysfunction and the predictive power of diastolic echocardiographic parameters for CV events in 194 incident ESRD patients, who started maintenance dialysis between July 2008 and August 2012 and had normal or near normal systolic function. Results: During a mean follow-up duration of 27.2 months, 57 patients (29.4%) experienced CV events. Compared

to CV Carnitine dehydrogenase Trametinib supplier event-free group, left ventricular (LV) mass index (LVMI), E/E′, LA volume index (LAVI), deceleration time (DT), and right ventricular systolic pressure (RVSP) were significantly higher, while LV ejection fraction (LVEF) and E′ were significantly lower in patients with CV events. In multivariate Cox proportional hazard analysis, LVEF, E/E′, LAVI, E/E′ > 15, and LAVI > 32 mL/m2 were demonstrated to be significant independent predictors of CV events even after adjusting for clinical and laboratory parameters. Among these, E/E′ > 15 and LAVI > 32 mL/m2 had significant power to predict CV events [E/E′ > 15: hazard ratio (HR) = 5.40, 95% confidence interval (CI) = 2.73–10.70, P < 0.001; LAVI > 32 mL/m2: HR = 5.56, 95% CI = 2.28–13.59, P < 0.001]. In addition, E/E′ and LAVI provided higher predictive values for CV events than other echocardiographic parameters. Kaplan-Meier analysis revealed that patients with both E/E′ > 15 and LAVI > 32 mL/m2 had the worst CV outcomes. Conclusion: Both elevated E/E′ and high LAVI were significant risk factors for CV events in incident dialysis patients with preserved LV systolic function.
