CRP and angina pectoris: In the SAP cohort, the highest C-index was shown for renal function with 0.66, followed by CRP with 0.65 and equally ejection fraction and multivessel disease with 0.64.In all, the highest C-index was achieved upon adding the traditional risk factors and the clincial variables to age and sex showing a C-index of 0.66 in the overall cohort and 0.67 in the stable angina cohort, thus allowing the most precise risk prediction.
