Adjusted for classical risk factors (age, sex, hypertension, dyslipidemia, diabetes mellitus and smoking), the odds ratio (OR) of V249I for CAD was 0.95 (95% confidence interval (CI)=0.78-1.15, p=0.61).
We examined the frequencies of V249I and T280M among early-onset CAD patients (G1; n = 149; <50 years), late-onset CAD patients (G2; n = 150; >65 years) and healthy controls (HC; n = 149, 47-93 years) without known CAD risk factors.
We investigated the effect of 5 common variations of chemokine and chemokine receptor genes (SDF1-3'A, CCR5-delta32, CCR2-64I, CX3CR1-V249I and CX3CR1-T280M) on predisposition to CAD.
Genotyping of the CX3CR1-V249I polymorphism was performed in a cohort of 339 white individuals who underwent cardiac catheterization (n=197 with and n=142 without CAD, respectively).
