High-sensitivity C-reactive protein and N-terminal pro-B-type natriuretic peptide in patients with stable coronary artery disease: a prognostic study within the CLARICOR Trial
Publikation: Bidrag til tidsskrift › Tidsskriftartikel › fagfællebedømt
BACKGROUND:
Patients with stable coronary artery disease (CAD) have a poor prognosis. The aim of the study was to evaluate the extent to which serum high-sensitivity C-reactive protein (hs-CRP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) measurement alone or together could be prognostic biomarkers in patients with stable CAD.
MATERIALS AND METHODS:
During the 2.6-year follow-up period 270 patients among the 4264 patients with stable CAD in the CLARICOR trial suffered myocardial infarction (MI) and 377 died (187 cardiovascular deaths (CVD)).
RESULTS:
Serum NT-proBNP was significantly associated with MI (hazard ratio (HR), 1. 65 (refers to a 2.72 fold increase in serum level, p = 0.0005), CVD (HR, 2.42, p < 0.0005) and non-CVD (HR, 1.79, p < 0.0005). When correcting for hs-CRP, NT-proBNP was still significantly associated with MI (HR, 1.63, p = 0.0005), CVD (HR, 2.36, p < 0.0005) and non-CVD (HR, 1.66, p < 0.0005). Serum hs-CRP was compared to NT-proBNP less associated with MI (HR, 1.20, p = 0.001), CVD (HR, 1.39, p < 0.0005) and non-CVD (HR, 1.67, p < 0.0005). When corrected for NT-proBNP, hs-CRP was only associated with non-CVD (HR, 1.51, p < 0.0005). When adjusting for cardiovascular risk factors hs-CRP predicted non-CVD (HR, 1.46) and all-cause death (HR, 1.24) and NT-proBNP predicted MI (HR, 1.50), CVD (HR, 1.98), non-CVD (HR, 1.39), and all-cause death (HR, 1.62)(p < 0.0005 for all).
CONCLUSION:
Increased serum NT-proBNP was a stronger predictor of MI, cardiovascular death and non-cardiovascular death than hs-CRP in patients with stable CAD. Once NT-proBNP was taken into account, hs-CRP did not improve predictions.
