We also investigated the extent to which established behavioral [cigarette smoking, alcohol consumption, body mass index (BMI) and physical activity] and biological coronary risk factors (blood pressure and lipids) [15], and novel coronary risk factors [CRP, interleukin-6 (IL-6), and von Willebrand factor (VWF)] [10,16], contribute to socioeconomic differences in CHD in older men in both relative and absolute terms. The gene discussed is IL6; the disease is coronary artery disorder.
