Heart failure affects liver morphology and function. What are the clinical implications?

Area of Science:

• Cardiology
• Hepatology
• Internal Medicine

Background:

• Liver dysfunction is a frequent and significant complication in patients with advanced or severe acute heart failure.
• Impaired hepatic circulation, due to congestion or hypoperfusion, underlies these liver lesions.
• Understanding these liver issues is vital for managing heart failure patients.

Purpose of the Study:

• To elucidate the distinct phenotypes of liver injury in heart failure.
• To highlight the clinical significance of differentiating congestive from ischemic liver lesions.
• To emphasize the importance of this knowledge for guiding acute decompensation treatment.

Main Methods:

• Clinical observation and biochemical marker analysis (bilirubin, alkaline phosphatase, transaminases).
• Histological examination of hepatic tissue to identify characteristic lesion types.
• Assessment of hepatic circulation indicators like inferior vena cava and hepatic vein dilation.

Main Results:

• Congestive liver lesions, marked by hepatomegaly and elevated direct bilirubin/alkaline phosphatase, are more common.
• Ischemic liver lesions, associated with hypoxemia and elevated total bilirubin/transaminases, indicate a poor prognosis if unaddressed.
• Impaired liver proteosynthetic function and abnormal liver function tests correlate with poor outcomes.

Conclusions:

• Differentiating between congestive and ischemic liver injury phenotypes in heart failure is essential for targeted treatment.
• Monitoring biochemical markers, hepatic perfusion, and liver stiffness aids in evaluating treatment efficacy and achieving euvolemia.
• Appropriate management of heart failure-related liver dysfunction can improve patient prognosis.
