After adjustment for age, sex, BMI, smoking status, hypertension status, diabetes status, hyperlipoidaemia, RBC, Hb, Cre, left main or multivessel disease and GRACE scores, multivariate Cox proportional hazards analysis suggested that the FAGR was still independently correlated with all-cause mortality (HR: 1.896, 95% CI: 1.185–3.304, p = 0.008) and cardiovascular mortality (HR: 1.684, 95% CI: 1.027–2.763, p = 0.039). The gene discussed is GSTM1; the disease is diabetes mellitus.
