Physiopathological and diagnostic aspects of cirrhotic cardiomyopathy

Area of Science:

• Cardiology
• Hepatology
• Internal Medicine

Background:

• Cirrhotic cardiomyopathy involves cardiac structural and functional changes in liver cirrhosis patients.
• It is often underdiagnosed and linked to poor outcomes in portal hypertension management and post-transplant.
• Clinical features include diastolic/systolic dysfunction, electrical conduction abnormalities (QTc prolongation), and impaired chronotropic response.

Purpose of the Study:

• To highlight the characteristics and diagnostic approaches for cirrhotic cardiomyopathy.
• To emphasize the clinical significance and underdiagnosed nature of this condition.
• To discuss the role of echocardiography and emerging techniques in its detection.

Main Methods:

• Review of clinical characteristics and diagnostic tools for cirrhotic cardiomyopathy.
• Emphasis on echocardiography, including E/A index for diastolic dysfunction and ejection fraction for systolic dysfunction.
• Exploration of pharmacological stress echocardiography for latent forms and longitudinal strain for early detection.

Main Results:

• Cirrhotic cardiomyopathy manifests as variable diastolic and systolic dysfunction.
• Elongated corrected QT interval and inadequate chronotropic response are key clinical signs.
• Echocardiography, particularly E/A index and ejection fraction, is a primary diagnostic tool.
• Pharmacological stress and longitudinal strain imaging show promise for detecting latent or early alterations.

Conclusions:

• Cirrhotic cardiomyopathy is an underdiagnosed entity with significant clinical implications.
• Echocardiography is essential for diagnosis, with emerging techniques offering improved early detection.
• Timely diagnosis and management are critical for improving outcomes in liver cirrhosis patients with cardiac involvement.
