How non-alcoholic fatty liver disease and cirrhosis affect the heart

Area of Science:

• Cardiology
• Hepatology
• Internal Medicine

Background:

• Liver diseases, including non-alcoholic fatty liver disease (NAFLD) and cirrhosis, are increasingly linked to cardiovascular complications.
• Cardiovascular issues represent a major cause of mortality in patients with advanced liver conditions.
• Histological liver changes (steatosis, fibrosis, cirrhosis) differentially impact the cardiovascular system.

Purpose of the Study:

• To review current understanding of the relationship between liver disease and cardiovascular complications.
• To explore the distinct pathophysiological mechanisms involved in cirrhotic cardiomyopathy (CCM) and NAFLD-related cardiovascular risks.
• To emphasize the importance of accurate diagnostic assessments for at-risk patients.

Main Methods:

• Literature review of current research on liver disease and cardiovascular interactions.
• Analysis of pathophysiological mechanisms linking liver histology to cardiac dysfunction.
• Discussion of diagnostic modalities for risk assessment and treatment evaluation.

Main Results:

• Patients with CCM and NAFLD face elevated risks of systolic/diastolic dysfunction and major cardiovascular events.
• Pathophysiological mechanisms vary based on the specific liver disease and its stage.
• Early and accurate symptom assessment is vital for patient management.

Conclusions:

• Cardiovascular complications are a critical concern in patients with NAFLD and cirrhosis.
• Understanding the specific mechanisms underlying these risks is essential for effective clinical management.
• Contemporary diagnostic tools are indispensable for identifying and managing at-risk individuals.
