Background Previous studies showed that blood B-type natriuretic peptide (BNP) level could predict the prognosis of acute coronary syndromes (ACS). This study investigated the evaluation value of circulating BNP for early percutaneous coronary intervention (PCI) in patients with ACS.Methods Nine hundred and sixty consecutive patients with ACS were enrolled. Circulating BNP level was measured when each patient arrived at the emergency room. All patients underwent PCI in 90 minutes in spite of contraindication. Cardiac events (death from any cause, heart failure, and recurrence of acute myocardial infarction or ACS) were recorded during follow-up. Results In patients with BNP ≥80 pg/ml, mortality from all causes within 1 month and 6 months in those underwent delayed PCI (≥6 hours) was significantly higher than those received early PCI (
