AbstractObjective: To evaluate the correlation between N-terminal probrainnatriuretic peptide (NT-proBNP) and the prognosis of death in hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease(COPD). Methods: A cohort study of 169 patients with acute exacerbations COPD. According to the age and NT-proBNP value measured on admission, cases were divided into 3 groups. The risk ratio of mortality among the three group were analyzed. Results: Thirty-two patients died within 1 year. There are 93 cases in group A (NT-proBNP < 300 ng/L), 45 cases in group B (aged 75 and below with NT-proBNP 300-900 ng/L, older than 75 with NT-proBNP 300-1 800 ng/L), 31 cases in group C (aged 75 and below with NT-proBNP>900 ng/L, older than 75 with NT-proBNP>1 800 ng/L); The in-hospital mortalities were 3.2%, 11.1% and 32.3%respectively, and mortalities within a year were 5.4%, 17.8% and 61.3% . The risk ratio (RR) and 95%CI for dying in hospital of group C to group A and B were 10.00 (3.61-56.50) and 2.90 (1.15-12.60), RR and 95%CI for dying within 1 years after hospitalization were 11.40 (8.78-88.46) and 3.45 (2.56-20.97, P<0.05). Conclusion: The NT-proBNP values measured at admission were associated with the short-term and long-term prognosis of patients with AECOPD.
