The prognostic role of cardiac dysfunction in cirrhotic patients is increasingly recognized. We studied its impact on morbidity and mortality before and after liver transplantation (LT) including development of post-transplant cardiovascular disease (CVD). In this retrospective study, cirrhotic patients who underwent LT assessment from January 2010 to December 2020 were reviewed. Demographics, cardiac investigations and clinical courses were analyzed to identify the prevalence of cardiac dysfunction and its role in LT outcomes. Survival analysis was performed using Cox proportional hazard regression modelling, with LT as a time-varying covariate and as an interaction variable with cardiac dysfunction. Three hundred and eight patients (70% male) were studied. The median (interquartile range) age at LT assessment was 56 (12) years. Cardiac dysfunction was found in 178 (58%) patients (diastolic, 169; systolic, 26; both, 17) and was significantly associated with hepatorenal syndrome/acute kidney injury and peri- and post-transplant morbidity (adjusted odds ratio [aOR] 1.94, 95% CI 1.06–3.52, P <.001; aOR 2.01, 95% CI 1.06–3.82, P =.033; aOR 1.9, 95% CI 1.01–3.65, P =.023, respectively). Cardiac dysfunction was not associated with mortality before (adjusted hazard ratio [aHR] 1.01, 95% CI.99–1.01) or after LT (aHR.74, 95% CI.4–1.05. Post-transplant CVD (61% cardiac failure) occurred in 36 patients, and there was no significant association with cardiac dysfunction (P =.11). Cardiac dysfunction was common in LT candidates and was significantly associated with morbidity before and after LT. Studies on the role of advanced echocardiographic parameters to improve diagnosis of cardiac dysfunction and optimize LT outcomes are needed.
