BackgroundIn patients with non-alcoholic fatty liver disease (NAFLD) cardiovascular diseases are more often the cause of death than the liver disease itself. However, the prevalence of atherosclerotic manifestations in individuals with NAFLD is still uncertain. This study aimed to explore the association between NAFLD and coronary artery calcification (CAC) in a Central European population.MethodsA total of 1,743 participants from the Paracelsus 10,000 study were included. The participants underwent CAC scoring and were assessed for fatty liver index (FLI), fibrosing non-alcoholic steatohepatitis Index (FNI) and fibrosis-4 index (FIB-4 score), which are indicators for steatosis and fibrosis. Multivariable logistic regression models were calculated.ResultsResults revealed an association between liver steatosis/fibrosis and CAC. A FLI > 60 was associated with higher odds of NAFLD (OR 3.38, 95% CI: 2.61-4.39, p < 0.01) and increased prevalence of CAC-Score >300 compared to FLI <30 (9% vs. 3%, p < 0.01), even after adjusting for traditional cardiometabolic risk factors. While the crude odds ratios of the FIB-4 scores ≥ 1.3 and FNI score were significantly associated with increased odds of CAC, they became non-significant after adjusting for age, sex, and MetS.ConclusionThis study reveals a significant association between NAFLD and CAC. The findings suggest that assessing liver fat and fibrosis could enhance assessment of cardiovascular risk, but further research is needed to determine whether hepatic fat plays an independent role in the development of atherosclerosis and whether targeting liver steatosis can mitigate vascular risk.The Author(s).
