Abstract
Background: The comparative prognostic value of low density lipoprotein-cholesterol (LDL-C) and C-reactive protein (CRP) in patients with stable coronary artery disease (CAD) treated with percutaneous coronary intervention (PCI) and statin therapy is poorly investigated. Methods: The study included 7595 patients with stable CAD treated with PCI. Based on a cut-off of 100. mg/dl for LDL-C and 3. mg/L for CRP, patients were divided into 4 groups: patients with LDL-C ≤ 100 mg/dl and CRP ≤3 mg/L (n = 2795); patients with LDL-C > 100 mg/dl and CRP ≤ 3 mg/L (n = 2091); patients with LDL-C ≤ 100 mg/dl and CRP > 3 mg/L (n = 1296); and patients with LDL-C > 100 mg/dl and CRP > 3 mg/L (n = 1413) Statins at discharge were prescribed in all patients. The primary outcome was 1-year all-cause mortality. Results: One-year mortality was 2.1% (160 deaths): 1.2% (33 deaths) among patients with LDL-C ≤ 100 mg/dl and CRP ≤ 3 mg/L, 1.4% (28 deaths) among patients with LDL-C > 100 mg/dl and CRP ≤ 3 mg/L, 4.8% (60 deaths) among patients with LDL-C ≤ 100 mg/dl and CRP > 3 mg/L and 2.9% (39 deaths) among patients with LDL-C > 100 mg/dl and CRP > 3 mg/L (P < 0.001). After adjustment, CRP (hazard ratio [HR] = 1.64, 95% confidence interval [CI] 1.33-2.02, for 1 standard deviation increase in the logarithmic scale) but not LDL-C (HR = 1.03 [0.90-1.17], for 30 mg/dl increase) showed an independent association with 1-year mortality. CRP (P = 0.045) but not LDL-C (P = 0.294) increased the discriminatory power of multivariable model for prediction of mortality. Conclusion: In patients with stable CAD treated with PCI and statin therapy, CRP but not LDL-C was independently associated with increased risk of 1-year mortality. © 2014 Elsevier Inc.
