Abstract
BACKGROUND: The presence of left ventricular diastolic dysfunction (LVDD) in patients with cirrhosis leads to a restriction of activities and a poor health related quality of life (HRQoL), which should be taken into consideration when treating them for liver and cardiac complications. AIMS: The prevalence, complications, predictors of HRQoL and survival in cirrhotic patients with LVDD were studied. METHODS: We report a prospective cohort study of 145 consecutive cirrhotic patients with LVDD who were evaluated for cardiac functional status at enrollment and followed up for hepatic complications, cardiac events, outcome and HRQoL using the Minnesota Living With Heart Failure Questionnaire (MLHFQ) over a period of 2 years. RESULTS: In total, 145 (mean age 61 years, 59% male) patients were included. Seventeen patients died with 10.5%, 22.5% and 40% mortality rates in patients with Grades 1, 2 and 3 LVDD respectively over 24 months. The parameters that were significant for predicting mortality on bivariate analysis were MELD, MELDNa, hepatic venous pressure gradient, MLHFQ, and left ventricular (LV) diastolic function (e' and E/e' ratio), but only MELD, MELDNa and E/e' remained significant on multivariate analysis. The E/e' ratio (8.7 ± 3.3 in survivors vs. 9.1 ± 2.3 in non-survivors) predicted outcome. On univariate analysis, the predictors of poor HRQoL were the Child-Pugh score ≥9.8 (OR 2.6; 95% confidence intervals (CI) 2.3-9.1, P = 0.041), MELD score ≥ 15.7 (OR 2.48; 95% CI 1.4-3.9, P = 0.029), refractory ascites (OR 1.9; 95% CI 1.1-6.1, P = 0.050), and E/e' ratio ≥7.6 (OR 1.9; 95% CI 1.8-7.1, P = 0.036) The presence of Class II/III (P = 0.046) symptoms of heart failure and MLHFQ≥ 45 (P = 0.042) were predictors of mortality at 24 months. CONCLUSION: The grade of LVDD correlates with liver function, clinical events, risk of renal dysfunction and HRQoL. Evaluation of novel therapies which target symptomatic improvement in LVDD, should be done with suitable outcome measures, including HRQoL assessment.
