Original Article High-sensitive C-reactive protein predicts outcome after coronary artery bypass

Background: Elevated high-sensitive C-reactive protein is a powerful independent predictor of cardiovascular events. However, there are scant data on its impact on midterm or long-term outcomes of coronary artery bypass grafting. Method: We analyzed data of 2863 patients who underwent coronary artery bypass in 2006–2007. Early endpoints were hospital mortality and major morbidity. Midterm endpoints were overall mortality, major adverse cardiovascular events, and heart failure. Results: During hospital stay, 26 patients died and 288 suffered major morbidity. After 3.6 years of follow-up, 56 patients had died, 105 had major adverse cardiovascular events, and 70 developed heart failure. Multivariate analysis revealed every 1 mgL1 increase of high-sensitive C-reactive protein was associated with increased odds ratio for early mortality (odds ratio = 2.50, p = 0.002), major morbidity (odds ratio = 1.38, p = 0.02), and hazard ratio for midterm mortality (hazard ratio = 1.68, p = 0.03), major adverse cardiovascular events (hazard ratio = 1.48, p = 0.04), and heart failure (haz-ard ratio = 1.88, p = 0.01).
