Purpose: Cardiovascular (CV) events remain a major source of morbidity and mortality following liver transplantation (LT). This review evaluates the incidence of and risk assessment for adverse CV outcomes following deceased donor adult liver transplantation.
Methods: MEDLINE via PubMed was searched for studies published between January 2002 and December 2015 (MELD era) with the assistance of a research librarian. Two authors independently reviewed articles to select eligible studies.
Results: Twenty-three studies were included, all retrospective analyses. Sixteen evaluated overall risk factors for CV outcomes following LT; 7 evaluated different forms of CV imaging for risk stratification. In total, 5604 patients from 15 unique cohorts, and 1943 from 7 unique cohorts were represented in the two categories respectively. Studies were heterogeneous with respect to definition of CV outcomes and follow-up duration. The incidence of CV outcomes <6 months post LT ranged from 7-41.6% whereas the incidence of CV outcomes >1 year post LT ranged from 3.9-28% (range 1-8.2 years). For combined CV outcomes, age at time of LT, history of coronary artery disease (CAD), and history of diabetes were the most consistent independent predictors of CV outcomes post LT on multivariate analyses . Studies focused on cardiac imaging demonstrated discordant results regarding sensitivity, specificity, and predictive value of dobutamine stress echocardiography, cardiac angiography and nuclear testing (SPECT) for predicting CV outcomes post LT.
Conclusions: Although limited by heterogeneity across studies, several variables were consistently identified as being independently predictive of CV outcomes following LT. Existing data are conflicting regarding the predictive value of various cardiac testing modalities for CV events post LT. Future prospective studies are needed to assess different risk stratification approaches and their effectiveness in optimizing CV outcomes post LT.
