Diastolic dysfunction characterizes cirrhotic cardiomyopathy

Area of Science:

• Cardiology
• Hepatology
• Internal Medicine

Background:

• Cirrhosis of the liver is frequently associated with cardiac abnormalities, collectively termed cirrhotic cardiomyopathy.
• The relationship between cirrhotic cardiomyopathy and the development of hepatorenal syndrome (HRS) remains incompletely understood.

Purpose of the Study:

• To investigate the prevalence of cirrhotic cardiomyopathy in patients with liver cirrhosis.
• To assess the correlation between cardiac dysfunction and the incidence of hepatorenal syndrome (HRS).

Main Methods:

• Echocardiography was used to evaluate cardiac parameters in 60 cirrhotic patients (30 alcoholic, 30 non-alcoholic) and 30 healthy controls.
• Patients were monitored for 12 months to track the development of HRS.

Main Results:

• Mild diastolic dysfunction (Grade I or II) was observed in 30% of cirrhotic patients.
• No significant differences in echocardiographic parameters were found between alcoholic and non-alcoholic cirrhotic patients, or across different Child-Pugh classes.
• Only deceleration time showed statistical significance; HRS developed in two patients, with no significant correlation to diastolic dysfunction.

Conclusions:

• Diastolic dysfunction is common in cirrhosis but typically mild and not linked to liver dysfunction severity.
• Cardiac parameters do not differ significantly between alcoholic and non-alcoholic cirrhosis.
• Diastolic dysfunction in cirrhosis is not correlated with HRS, circulatory dysfunction, or ascites, and does not impact one-year survival.
