Abstract
OBJECTIVE: Although E/e´ is prognostic of mortality in patients with end-stage renal disease (ESED), little is known about the prognostic implications of E/e´ following kidney transplant (KT). The objective of this study was to evaluate whether an elevated E/e´ is associated with graft function, postoperative hemodialysis, and overall mortality in end-stage renal disease patients following KT. DESIGN: A retrospective observational study. SETTING: Tertiary teaching hospital. PARTICIPANTS: In total, 1,045 patients underwent KT at the authors' hospital between January 2006 and December 2013. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: Patients were divided into groups with an E/e´<15 or≥15, as assessed by preoperative echocardiography (median time from preoperative assessment of echocardiography to surgery: 37 days [IQR: 16-68 days]). Of 1,045 patients, 821 patients (78.6%) had an E/e´<15, and 224 patients (21.4%) had an E/e´≥15. Multivariate analysis indicated that age (odds ratio [OR]: 1.03; 95% confidence interval [CI]: 1.01-1.04, p = 0.001), diabetes mellitus (OR: 2.7; CI: 1.94-3.83, p<0.001), β-blocker (OR: 1.4; CI: 1.03-1.95, p = 0.034), left atrial dimension (OR: 1.07; CI: 1.04-1.11, p<0.001), and left ventricular mass index (OR: 1.02; CI: 1.01-1.03, p<0.001) are predictive of E/e´≥15. After adjustment using inverse probability of treatment weighting, E/e´≥15 also was associated independently with postoperative hemodialysis (OR: 2.0; 95% CI: 1.5-2.6, p<0.001), graft failure (OR: 1.7; 95% CI: 1.4-2.2; p<0.001), and overall mortality (hazard ratio [HR]: 3.2; 95% CI: 2.1-4.8, p<0.001). CONCLUSIONS: Preoperative E/e´ is a prognostic indicator of overall mortality in ESRD patients undergoing KT.
