Abstract
Aim. To evaluate the information content of genetic risk scores (GRSs) for coronary artery disease (CAD), previously developed on European populations, in representatives of the Russian population.Material and methods. The work involved 1685 people from the ESSE-Ivanovo epidemiological study. CAD was verified in 3,1% of individuals. The coronary composite endpoint was assessed annually during 8-year follow-up. Next generation sequencing was performed using a targeted panel. Logistic regression analysis and area under the ROC curve (AUC) were used. Age, sex, and smoking status were taken into account in the multivariate model.Results. Of the 16 GRSs included in the analysis, only 2 GRSs demonstrated significance in the univariate analysis of association with CAD (highest AUC — 0,577). In a multivariate model, with an increase by 1 standard deviation (SD) for the 6 studied GRSs, a significant association with CAD was obtained — the odds ratio varied in the range of 1,31-1,47. The two GRSs demonstrated significant differences in the incidence of CAD between the groups corresponding to the upper and lower quintiles. Forty-five endpoints were registered. The risk ratio for the end point with an increase in GRS by 1 SD, taking into account cofactors, exceeded statistical significance for the 9 analyzed GRS and was in the range of 1,36-1,54.Conclusion. For the first time in Russia, 16 CAD GRSs, previously developed on European samples, was validated. The results were reproduced only for a few of the studied CAD SGRs.
