Heart Failure and Liver Disease: Cardiohepatic Interactions.

Heart failure (HF) and liver disease often co-exist. This is because systemic disorders and diseases affect both organs (alcohol abuse, drugs, inflammation, autoimmunity, infections) and because of complex cardiohepatic interactions. The latter, which are the focus of this review, include the development of acute cardiogenic liver injury and congestive hepatopathy in HF as well as cardiac dysfunction and failure in the setting of liver cirrhosis, nonalcoholic fatty liver disease, and sequelae following liver transplantation. The emerging role of altered liver X receptor signaling in the pathogenesis of HF comorbidities as well as of the intestinal microbiome and its metabolites in HF and liver disease are fruitful areas for future research.
