Cardiovascular dysfunction in patients with liver cirrhosis

Area of Science:

• Cardiovascular Medicine
• Hepatology
• Internal Medicine

Background:

• Cirrhosis frequently leads to hyperdynamic syndrome, characterized by increased heart rate and cardiac output, and reduced systemic vascular resistance.
• Peripheral and splanchnic vasodilatation, driven by altered vasodilator and vasoconstrictor factors, underlies this hyperdynamic state.
• Cirrhotic cardiomyopathy encompasses impaired cardiac contractility, diastolic dysfunction, and electrophysiological abnormalities in cirrhotic patients.

Approach:

• This review synthesizes current literature on circulatory and cardiovascular dysfunctions in cirrhosis.
• It examines the pathophysiologic mechanisms contributing to these conditions.
• Clinical implications, including impacts on hepatorenal syndrome and post-procedural complications, are discussed.

Key Points:

• Cardiovascular dysfunction is central to hepatorenal syndrome development in advanced cirrhosis.
• Liver transplantation and transjugular intrahepatic portosystemic shunt (TIPS) insertion can precipitate cardiovascular complications.
• Common complications include pulmonary edema, heart failure, arrhythmias, pulmonary hypertension, pericardial effusion, and cardiac thrombus.

Conclusions:

• Cirrhosis-induced cardiovascular changes have profound clinical significance.
• Understanding these dysfunctions is crucial for managing cirrhotic patients and improving outcomes after interventions.
• Further research into pathophysiologic mechanisms and clinical management is warranted.
