| description | Shihui Fu,1,2,* Leixing Xie,2,* Dongyun Li,1,2 Ping Ye,1 Leiming Luo11Department of Geriatric Cardiology, 2Department of Cardiology and Hainan Branch, Chinese People’s Liberation Army General Hospital, Beijing, People’s Republic of China*These authors are joint first authorsObjective: This study was conducted to research the prognostic utility of N-terminal pro-B-type natriuretic peptide (NT-proBNP), compare the utility of the Seattle Heart Failure Score (SHFS) with NT-proBNP, develop a risk-evaluation model based on NT-proBNP, assess the associations of NT-proBNP with patient characteristics, and screen for decisive factors of NT-proBNP in Chinese elderly with chronic heart failure (CHF).Patients and methods: There were 306 patients (≥60 years) with CHF chosen as study subjects. Each one received an assessment of NT-proBNP on serum. The end point was all-cause mortality during a mean follow-up period of 471 days.Results: Subjects had a median age of 85 (60–100) years, a median NT-proBNP of 1,743.4 pg/mL, and a median SHFS of 1.87. During the follow-up period, 104 deaths occurred. NT-proBNP was significantly related to mortality (odds ratio 1.603, 95% confidence interval 1.407–1.826; P<0.001) and the significance persisted after full adjustment (odds ratio 1.282, 95% confidence interval 1.103–1.489; P=0.001). Age, New York Heart Association class IV CHF, plasma albumin, and neutrophils/lymphocytes were also independent predictors for mortality (P<0.05 for all). NT-proBNP and the SHFS showed similar predictive capacities (0.736 versus 0.796, P=0.105). The addition of NT-proBNP to the SHFS (0.818 versus 0.796, P=0.168) generated marginal growth in the c-statistic. The model based on NT-proBNP consisting of all selected predictors in this study, including age, New York Heart Association class IV CHF, plasma albumin, neutrophils/lymphocytes, and NT-proBNP, had a moderately higher c-statistic compared with the SHFS (0.846 versus 0.796, P=0.066). NT-proBNP was bound with the SHFS (r=0.500, P<0.001). Characteristics regarding general condition, inflammation, and cardiac and renal function were the decisive factors of NT-proBNP (P<0.05 for all).Conclusion: As a comprehensive representation of the patient characteristics described earlier, NT-proBNP values provided significant prognostic power similar to the SHFS in Chinese elderly with CHF. A novel model based on NT-proBNP could offer help for risk stratification.Keywords: NT-proBNP, prognosis, chronic heart failure, elderly |
