Cirrhotic cardiomyopathy (CCM) is a recognized but understudied and not well understood complication of cirrhosis. CCM is defined as subclinical (i.e., silent) heart dysfunction identified by echocardiography in patients with cirrhosis in the absence of other heart diseases such as significant coronary artery, valvular, or pericardial disease. Initial small studies indicate that CCM is common and it warrants larger prospective study in humans to address unanswered questions highly relevant to clinical care. These include 1) what are the associations between CCM and cirrhosis-related outcomes, adverse cardiac events, and survival 2) what clinical factors increase the risk for CCM, and 3) do bile acids levels, which are produced by the liver, in the blood associate with features of CCM.
