Background and Aim Metabolic dysfunction‐associated steatotic liver disease (MASLD) has been proposed as an alternative for the validated definition of metabolic dysfunction‐associated fatty liver disease (MAFLD). We compared the abilities of MAFLD and MASLD to predict the risk of atherosclerotic cardiovascular disease (ASCVD). Methods Six thousand and ninety six participants from the 2017 to 2020 National Health and Nutrition Examination Survey cohort who received a thorough medical health check‐up were chosen for the study. The associations between fatty liver status and coronary risk surrogates, such as 10‐year ASCVD risk and self‐reported cardiovascular events, were analysed. Results MAFLD and MASLD were identified in 2911 (47.7%) and 2758 (45.2%) patients, respectively. MAFLD (odds ratio [OR]: 2.14, 95% confidence interval [CI], 1.78–2.57, p < .001) was more strongly independently associated with high ASCVD risk than MASLD (OR: 1.82, 95% CI, 1.52–2.18, p < .001) was in comparison with the absence of each condition. However, compared with MAFLD, MASLD alone was not associated with increased ASCVD risk. Multiple logistic regression revealed that MAFLD alone was significantly more strongly associated with a high risk of ASCVD (OR: 2.82; 95% CI: 1.13–7.01; p < .03) than MASLD alone. Conclusions Although both MAFLD and MASLD were associated with different ASCVD risks, MAFLD predicted the ASCVD risk better than MASLD. The higher predictive ability of MAFLD compared to MASLD was attributed to metabolic dysfunction rather than moderate alcohol use.
