Black and Hispanic populations already carry a disproportionate MASLD burden, yet cardiovascular and hepatic risks across race, sex and ethnicity in Met-ALD remain poorly defined. Methods: Adults with Met-ALD recorded in the U.S. TriNetX electronic-health-record network (2010-2020) were identified by AASLD criteria. Patients with pre-existing major adverse cardiovascular events (MACE), major adverse liver outcomes (MALO), liver transplant, or viral/cholestatic liver disease were excluded. Propensity-score matching (1:1) balanced age, sex, race, BMI, comorbidities, tobacco and alcohol use, cardiovascular medications, bariatric surgery, GLP-1 agonist and insulin exposure. Five-year MACE and MALO were primary endpoints; myocardial infarction, stroke, acute heart failure, decompensated cirrhosis, hepatocellular carcinoma (HCC), liver transplant, all-cause death and hospitalization were secondary. Results: Fifty-eight thousand one hundred thirteen patients met inclusion (mean age 54 ± 14 yr; 64.8% male; 68.4% White; 10.3 % Hispanic). Compared with Whites, Blacks had higher odds of MACE (adjusted odds ratio [aOR] 1.13, 95 % CI 1.01–1.25) and stroke (aOR 1.45, 1.20–1.76), whereas Asians had lower five-year mortality (aOR 0.60, 0.38–0.97). Male sex predicted greater risks of MACE (aOR 1.17, 1.07–1.27), heart failure (aOR 1.20, 1.04–1.39) and death (aOR 1.13, 1.03–1.25) but lower MALO (aOR 0.89, 0.74–0.97) than female sex. Hispanics experienced reduced MACE (aOR 0.85, 0.72–1.00), decompensated cirrhosis (aOR 0.67, 0.51–0.88) and mortality (aOR 0.66, 0.54–0.79) versus non-Hispanics, with no ethnicity-based differences in MALO, HCC or transplant. Discussion: Black race and male sex independently confer excess cardiovascular morbidity and mortality in Met-ALD, whereas Hispanic ethnicity shows a paradoxical survival and hepatic advantage; Asian race associates with lower mortality. Clarifying biological, behavioural and care-access mechanisms underlying these trajectories is essential to develop equitable, culturally responsive prevention and treatment strategies.
