AbstractWe conducted a meta-analysis of the utility of pre-operative B-type natriuretic peptide (BNP) and N-terminal-pro B-type natriuretic peptide in predicting early (< 30 days) and intermediate (< 180 days) term mortality and major adverse cardiac events (cardiac death and nonfatal myocardial infarction) in patients following vascular surgery. A Pubmed Central and EMBASE search was conducted up to January 2008. Of 81 studies identified, seven prospective observational studies were included in the meta-analysis representing five patient cohorts: early outcomes (504 patients) and intermediate-term outcomes (623 patients). A B-type natriuretic peptide or N-terminal-pro B-type natriuretic peptide above the optimal discriminatory threshold determined by receiver operating characteristic curve analysis was associated with 30-day cardiac death (OR 7.6, 95% CI 1.33-43.4, p = 0.02), nonfatal myocardial infarction (OR 6.24, 95% CI 1.82-21.4, p = 0.004) and major adverse cardiac events (OR 17.37, 95% CI 3.31-91.15, p = 0.0007), and intermediate-term, all-cause mortality (OR 3.1, 95% CI 1.85-5.2, p < 0.0001), nonfatal myocardial infarction (OR 2.95, 95% CI 1.17-7.46, p = 0.02) and major adverse cardiac events (OR 3.31, 95% CI 2.1-5.24, p < 0.00001). B-type natriuretic peptide and N-terminal-pro B-type natriuretic peptide are potentially useful pre-operative prognostic tests in vascular surgical patients.
