Cirrhotic cardiomyopathy: comprehensive insights into pathophysiology, diagnosis, and management

Area of Science:

• Cardiology
• Hepatology
• Internal Medicine

Background:

• Cirrhotic cardiomyopathy (CCM) is a cardiac dysfunction associated with chronic liver disease.
• It is characterized by impaired cardiac response to stress, systolic and diastolic dysfunction, and electrophysiological changes like QT prolongation.

Purpose of the Study:

• To summarize the understanding of cirrhotic cardiomyopathy, including its pathophysiology, clinical presentation, diagnosis, and management.
• To highlight the importance of early CCM detection in patients with liver disease, particularly those awaiting liver transplantation.

Main Methods:

• Review of existing literature on cirrhotic cardiomyopathy.
• Analysis of diagnostic methods including echocardiography, biomarkers (NT-proBNP, troponins), and electrocardiography.
• Discussion of management strategies and challenges in the context of cirrhosis.

Main Results:

• CCM involves systemic inflammation, nitric oxide-induced vasodilation, and neurohormonal dysregulation.
• Patients may be asymptomatic at rest but show intolerance to stress or heart failure.
• Liver transplantation is the most definitive treatment for severe CCM.

Conclusions:

• CCM is a significant complication of chronic liver disease that requires careful diagnosis and management.
• Early identification of CCM is critical for improving outcomes in patients with liver disease, especially before liver transplantation or major surgery.
• Further research is needed to refine diagnostic criteria and therapeutic strategies for CCM.
