Few studies have simultaneously investigated the role of soluble tumor necrosis factor a (TNFa ) receptors types 1 and 2 (sTNF-R1 and sTNF-R2), C-reactive protein, and interleukin-6 as predictors of cardiovascular events. The value of these inflammatory markers as independent predictors remains controversial. methods We examined plasma levels of sTNF-R1, sTNF-R2, interleukin-6, and C-reactive protein as markers of risk for coronary heart disease among women participating in the Nurses’ Health Study and men participating in the Health Professionals Follow-up Study in nested case–control analyses | Inflammatory Markers and the Risk of Coronary Heart Disease in Men and Women Inflammatory Markers and the Risk ofCoronary Heart Disease in Men and Women Jennifer K.

The value of these inflammatory markers as independent predictors remains controversial. methods We examined plasma levels of sTNF-R1 sTNF-R2 interleukin-6 and C-reactive protein as markers of risk for coronary heart disease among women participating in the Nurses Health Study and men participating in the Health Professionals Follow-up Study in nested case-control analyses. Among participants who provided a blood sample and who were free of cardiovascular disease at baseline 239 women and 265 men had a nonfatal myocardial infarction or fatal coronary heart disease during eight years and six years of follow-up respectively. Using risk-set sampling we selected controls in a 2 1 ratio with matching for age smoking status and date of blood sampling. results After adjustment for matching factors high levels of interleukin-6 and C-reactive protein were significantly related to an increased risk ofcoronary heart disease in both sexes whereas high levels of soluble TNF-a receptors were significant only among women. Further adjustment for lipid and nonlipid factors attenuated all associations only C-reactive protein levels remained significant. The relative risk among all participants was for those with C-reactive protein levels ofat least mg per liter as compared with those with levels ofless than mg per .
