Objective To investigate the association between metabolic associated fatty liver disease(MAFLD)and the risk of atherosclerotic cardiovascular disease(ASCVD),and to provide data support for the prevention and treatment of such metabolic-associated diseases in clinical practice.Methods An observation cohort was established for the workers of Kailuan who underwent physical examination for the first time from June 2006 to October 2007 and had complete liver assessment data,without the history of malignant tumor,MAFLD or ASCVD.According to the presence or absence of MAFLD,the patients were divided into non-MAFLD group with 67 565 patients and MAFLD group with 29 004 patients,and according to the presence or absence of ASCVD,the patients were divided into non-ASCVD group with 69 141 patients and ASCVD group with 481 patients.The group t-test or the Wilcoxon rank-sum test was used for comparison of continuous data between the two groups.The χ2 test was used for comparison of categorical data between the two groups.The life-table method was used to calculate the cumulative incidence rates of new-onset ASCVD and MAFLD;the Kaplan-Meier method was used to plot the survival curves of the cumulative incidence rates of ASCVD in the MAFLD group and the non-MAFLD group and the cumulative incidence rates of MAFLD in the ASCVD group and the non-ASCVD group,and the log-rank test was used for comparison of cumulative incidence rates between two groups.A multivariate Cox proportional-hazards regression model analysis was used to investigate the impact of MAFLD on the risk of ASCVD and the impact of ASCVD on the risk of MAFLD.Results Compared with the non-MAFLD group,the MAFLD group had significantly higher levels of body mass index(BMI),waist circumference,systolic blood pressure(SBP),diastolic blood pressure(DBP),resting heart rate,alanine aminotransferase,uric acid(UA),fasting blood glucose(FBG),triglyceride(TG),total cholesterol,low-density lipoprotein cholesterol,and high sensitivity C-reactive protein(hs-CRP),as well as significanty lower levels of estimated glomerular filtration rate(eGFR)and high-density lipoprotein cholesterol(all P<0.05).Compared with the non-ASCVD group,the ASCVD group had significantly higher levels of BMI,waist circumference,SBP,DBP,UA,FBG,TG,and hs-CRP and a significantly lower level of eGFR(all P<0.05).The incidence rate of new-onset ASCVD continued to increase over time in the MAFLD group and the non-MAFLD group,while the incidence rate of new-onset MAFLD firstly increased and then remained stable over time in the ASCVD group and the non-ASCVD group.There were 4 263 cases(14.70%)of new-osnet ASCVD in the MAFLD group,with an incidence density of 12.90 per 1 000 person-years,while there were 6 529 cases(9.66%)of new-osnet ASCVD in the non-MAFLD group,with an incidence density of 8.24 per 1 000 person-years,and there were significant differences in the incidence density and cumulative incidence rate of ASCVD between the two groups(χ2=519.09 and 531.80,both P<0.05).There were 148 cases(30.77%)of new-onset MAFLD in the ASCVD group,with an incidence density of 40.10 per 1 000 person-years,while there were 32 194 cases(46.56%)of new-onset MAFLD in the non-ASCVD group,with an incidence density of 57.59 per 1 000 person-years,and there were significant differences in the incidence density and cumulative incidence rate of MAFLD between the two groups(χ2=19.29 and 30.78,both P<0.05).The corrected multivariate Cox proportional-hazards regression model analysis showed that MAFLD was a risk factor for new-onset ASCVD(hazard ratio[HR]=1.11,95%confidence interval[CI]:1.06-1.16,P<0.001),while ASCVD was a protective factor against new-onset MAFLD(HR=0.72,95%CI:0.61-0.85,P<0.001).Conclusion There is a significant association between MAFLD and ASCVD,with an increase in the risk of ASCVD in the MAFLD population and a reduction in the risk of MAFLD in the ASCVD population.
