Cardiac imaging in patients with chronic liver disease

Area of Science:

• Cardiology
• Hepatology
• Medical Imaging

Background:

• Cirrhotic cardiomyopathy (CCM) presents with impaired cardiac contractility, diastolic dysfunction, and electrophysiological abnormalities.
• CCM is linked to hepatic nephropathy and reduced patient survival.
• The cardiac manifestations of cirrhosis are not fully understood, necessitating advanced diagnostic approaches.

Purpose of the Study:

• To review the current understanding and diagnostic modalities for cirrhotic cardiomyopathy (CCM).
• To highlight the role of various cardiac imaging techniques in assessing CCM.
• To emphasize the need for further research into cardiac changes in cirrhotic patients.

Main Methods:

• Review of existing literature on cirrhotic cardiomyopathy and cardiac imaging.
• Discussion of stress testing (physiological and pharmacological) for systolic dysfunction assessment.
• Focus on echocardiography, including tissue Doppler and strain techniques, for diastolic and systolic dysfunction evaluation.

Main Results:

• Echocardiography with tissue Doppler is the primary method for detecting diastolic dysfunction (E/A, E/E' ratios).
• New myocardial strain techniques show potential for evaluating resting systolic dysfunction in CCM.
• Experience with cardiac MRI and CT for CCM is limited, requiring further investigation.

Conclusions:

• Cardiac imaging plays a vital role in characterizing and monitoring cirrhotic cardiomyopathy.
• Echocardiography is currently the most utilized modality for CCM assessment.
• Future research should explore advanced imaging techniques to better understand and manage CCM.
