NAFLD and Increased Aortic Stiffness: Parallel or Common Physiopathological Mechanisms?

Area of Science:

• Hepatology
• Cardiology
• Vascular Biology

Background:

• Non-alcoholic fatty liver disease (NAFLD) is the primary cause of chronic liver disease globally.
• NAFLD-related liver inflammation and fibrosis escalate disease progression and mortality.
• Emerging evidence links NAFLD to atherosclerotic vascular disease, independent of traditional risk factors.

Purpose of the Study:

• To review existing literature on the association between NAFLD and aortic stiffness.
• To elucidate the interplay between NAFLD and aortic stiffness.
• To identify potential common pathophysiological mechanisms linking these conditions.

Main Methods:

• Systematic literature search for studies investigating NAFLD and aortic stiffness.
• Analysis of data on carotid-femoral pulse wave velocity (cf-PWV) as a measure of aortic stiffness.
• Review of studies examining cardiovascular risk factors in NAFLD patients.

Main Results:

• Published studies consistently report a strong association between NAFLD and increased aortic stiffness.
• Increased aortic stiffness, measured by cf-PWV, is a predictor of cardiovascular events.
• NAFLD may contribute to atherosclerosis through shared inflammatory and metabolic pathways.

Conclusions:

• NAFLD is significantly associated with increased aortic stiffness.
• Arterial stiffness may serve as a marker for cardiovascular risk in NAFLD patients.
• Further research into shared pathophysiological mechanisms is warranted to inform clinical management.
