Background/PurposeCardiovascular disease (CVD) is the leading cause of death among individuals with non-alcoholic fatty liver disease (NAFLD). Recently, NAFLD was renamed metabolic-associated fatty liver disease (MAFLD). This study aimed to compare cardiovascular risk (CVR) and CVD between patients with NAFLD and MAFLD.MethodsRetrospective cross-sectional study of biopsy-proven liver steatosis performed between 2013 and 2018 at a university hospital. Cases were divided into NAFLD or MAFLD and demographic, clinical, and laboratory data were collected to assess CVR (through the atherosclerotic cardiovascular disease risk estimator and atherogenic indices) and CVD.ResultsOut of 1233 liver biopsies, 171 (13.9%) presented steatosis. Of these, 109 patients met diagnostic criteria for NAFLD (63.7%) and 154 (90.1%), for MAFLD. In the NAFLD group, 78% of the cases had steatohepatitis, 24.8% had cirrhosis, and 3.7%, hepatocellular carcinoma (HCC). In the MAFLD group, 72.7% of the cases had liver inflammatory activity, 28.6% had cirrhosis, and 13.6% had HCC. In patients with MAFLD and NAFLD, CVR was intermediate/high (36.4 and 25.7%, p = 0.209) and CVD occurred in 20.1 and 12.8% (p = 0.137) of the cases, respectively, with no influence of liver injury severity. We observed a significant increase in high 10-year CVR (p = 0.020) and CVD (p = 0.007) in patients with MAFLD and concomitant viral infection (HCV and/or HBV) compared to cases with MAFLD only.ConclusionPatients with both NAFLD and MAFLD had intermediate/high CVR, with a high rate of CVD. Patients with MAFLD and concomitant viral infection showed significantly increased CVR and CVD compared to those without viral infection.
