Association Between Cardiovascular Health and Cirrhosis and Mortality: Insights From a Comprehensive Cross-sectional Study.

Goal: We aim to explore the relationship between the newly introduced CVH indicator "Life's Essential 8 (LE8)" and cirrhosis.

Background: The global burden of cirrhosis is increasing, with a rising number of deaths, leading to significant societal and economic challenges. Cardiovascular health (CVH) has been found to have potential associations with liver diseases.

Materials and methods: All participants aged 20 and older from National Health and Nutrition Examination Survey 2005 to 2018 were included. CVH was accessed by LE8, consisting of 4 health behaviors (diet, physical activity, nicotine exposure, and sleep health) and 4 health factors (body mass index, lipid levels, blood sugar, and blood pressure). Cirrhosis was determined based on abnormal liver function test results, with an aspartate aminotransferase to platelet ratio index >2. Participants' mortality status was obtained by matching with the National Death Index and all-cause mortality served as the follow-up endpoint.

Results: This extensive cross-sectional study reveals that LE8 was not associated with cirrhosis. A higher health behaviors score was associated with lower cirrhosis. Moreover, there is an inverse U-shaped relationship between the LE8 score and all-cause mortality in participants with cirrhosis, signifying a decrease in all-cause mortality when LE8 surpasses 60. A greater health behaviors score is linked to a decreased proportion of all-cause mortality in cirrhosis patients.

Conclusion: Maintaining better health behaviors may be beneficial for cirrhosis, especially through a balanced diet, regular exercise, smoking cessation, and quality sleep.
