Plasma N-terminal pro-B-type natriuretic peptide for prediction of death or nonfatal myocardial infarction following percutaneous coronary intervention

B-type natriuretic peptide (BNP) and the N-terminus of pro-BNP (NT-pro-BNP) have prognostic value in patients with heart failure and patients with acute coronary syndromes. Little is known about the prognostic value of baseline NT-pro-BNP alone or in combination with C-reactive protein (CRP) for clinical outcome after percutaneous coronary intervention (PCI). Within a single center registry of contemporaneous PCI, we investigated the prognostic value of baseline plasma NT-pro-BNP and CRP concentrations for the prediction of death or nonfatal myocardial infarction (MI) during 12 to 14 months of follow-up. Among 1, 172 consecutive patients, the occurrence of death or MI increased significantly with baseline NT-pro-BNP before PCI (first quartile 0 of 294, second quartile. 6 of 291 [2.1%], third quartile 4 of 294 [1.4%], fourth quartile 22 of 293 [7.5%)]; p 65 years and NT-pro-BNP as independent significant predictors of death/Ml (age OR 3.18, 95% Cl 1.32 to 7.67, p = 0.01; NT-pro-BNP OR 4.57, 95% Cl 2.07 to 10.10, p = 0.0001). Baseline NT-pro-BNP before PCl provides important, independent prognostic information for the occurrence of death or nonfatal MI during long-term follow-up. (C) 2004 by Excerpta Medica Inc
