In multivariable logistic regressions adjusted for age, sex, hypertension, treatment for dyslipidemia and diabetes, and in stable CAD patients also with atrial fibrillation, elevated levels of IL-4 (p = 0.003), IFN-γ (0.009) and lower level of MCP-3 (p = 0.009) and SCGF-β (p = 0.006) were independent predictors for stable CAD compared to controls in the CAREBANK cohort. Here, IFNG is linked to atrial fibrillation.
