Serum B-type natriuretic peptide levels on admission predict not only short-term death but also angiographic success of procedure in patients with acute ST-elevation myocardial infarction treated with primary angioplasty

B-type natriuretic peptide (BNP) levels are predictive of short-term death in patients with acute coronary syndromes. Few data are available for BNP levels obtained on admission in patients with acute ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). Blood samples for BNP estimation, obtained on admission in 126 consecutive patients (mean age, 58.8 ± 10.7 years) with STEMI, were measured at the bedside by using a simple point-of-care test in a 15-minute period before PCI. Follow-up up to 42 days was performed. A baseline BNP value of 331 pg/mL had a sensitivity of 87.9% and a specificity of 90% for predicting death in a follow-up study. There was no difference in subgroups by median BNP (100 pg/mL) in Thrombolysis In Myocardial Infarction (TIMI) flow grade 3 before PCI, although higher BNP levels were observed among patients with TIMI
