Abstract
Emerging evidence and perspectives have pointed towards the heart playing an important role in hepatorenal syndrome (HRS), outside of conventional understanding that liver cirrhosis is traditionally considered the sole origin of a cascade of pathophysiological mechanisms directly affecting the kidneys in this context. In the absence of established heart disease, cirrhotic cardiomyopathy may occur more frequently in those with liver cirrhosis and kidney disease. It is a specific form of cardiac dysfunction characterized by blunted contractile responsiveness to stress stimuli and altered diastolic relaxation with electrophysiological abnormalities. Despite the clinical description of these potential cardiac-related complications of the liver, the role of the heart has traditionally been an overlooked aspect of circulatory dysfunction in HRS. Yet from a physiological sense, temporality (prior onset) of cardiorenal interactions in HRS and positive effects stemming from portosystemic shunting demonstrated an important role of the heart in the development and progression of kidney dysfunction in cirrhotic patients. In this review, we discuss current concepts surrounding how the heart may influence the development and progression of HRS, and the role of systemic inflammation and endothelial dysfunction causing circulatory dysfunction within this setting. The temporality of heart and kidney dysfunction in HRS will be discussed. For a subgroup of patients who receive portosystemic shunting, the dynamics of cardiorenal interactions following treatment is reviewed. Continued research to determine the unknowns in this topic is anticipated, hopefully to further clarify the intricacies surrounding the liver-heart-kidney connection and improve strategies for management.
Core Tip: There is emerging evidence to suggest that the heart plays an important role in advanced liver disease and contributes significantly to hepatorenal syndrome (HRS) progression. It is now increasingly agreed upon that circulatory dysfunction in HRS is at least in part due to cardiac impairment, which can exist prior to kidney dysfunction in cirrhotic patients who develop HRS. There are numerous pathophysiological mechanisms which may co-exist in both hepatorenal and cardiorenal syndrome pathways, and treatments which ameliorate kidney dysfunction in HRS are likely to also address the mechanisms which lie within this intricate hepatocardiorenal syndrome entity that is being postulated.
