C-Reactive Protein Modulates Risk Prediction Based on the Framingham Score

Abstract

Background— The Framingham Coronary Heart Disease (CHD) prediction score is recommended for global risk assessment in subjects prone to CHD. Recently, C-reactive protein (CRP) has emerged as an independent predictor of CHD. We sought to assess the potential of CRP measurements to enhance risk prediction based on the Framingham Risk Score (FRS) in a large cohort of middle-aged men from the general population. Methods and Results— We measured CRP and traditional cardiovascular risk factors at baseline in 3435 white men of German nationality, 45 to 74 years of age. All men were drawn from 3 random samples of the general population in the Augsburg area located in Southern Germany in 1984 to 1985, 1989 to 1990, and 1994 to 1995 (response rate, 80%), and the FRS was calculated in all of them. Outcome was defined as nonfatal and fatal coronary events, including sudden cardiac death. During an average follow-up of 6.6 years, a total of 191 coronary events occurred. Cox regression showed a significant contribution...
