Advances in cirrhotic cardiomyopathy

Area of Science:

• Cardiology
• Hepatology
• Translational Medicine

Background:

• Cirrhotic cardiomyopathy (CCM) is a recognized cardiac complication in patients with cirrhosis.
• CCM can lead to overt cardiac dysfunction, particularly during challenges like liver transplantation, increasing morbidity and mortality.
• Recent expert groups have proposed revised diagnostic criteria for CCM, necessitating further validation.

Purpose of the Study:

• To review and detail further pathogenic mechanisms of CCM beyond previously summarized pathways.
• To discuss recent studies on therapeutic strategies for CCM.
• To highlight the clinical relevance of CCM in the context of liver transplantation and identify unmet needs in its management.

Main Methods:

• Comprehensive literature review focusing on recent advancements in CCM research.
• Analysis of studies detailing molecular and cellular mechanisms of CCM.
• Evaluation of current and emerging therapeutic approaches for CCM.

Main Results:

• CCM involves complex mechanisms including myosin heavy chain isoform shifts and cellular calcium transient abnormalities.
• The review details additional contributing factors such as cardiomyocyte apoptosis, inflammation, and oxidative stress.
• Recent work emphasizes CCM's critical role in the perioperative period following liver transplantation.

Conclusions:

• CCM is a clinically significant syndrome associated with cirrhosis, contributing to poor outcomes.
• While new diagnostic criteria exist, pathogenic mechanisms require further elucidation.
• Optimal management strategies for CCM remain a critical unmet need, demanding extensive future research.
