【 摘 要 】

BackgroundB-type natriuretic peptide (BNP) levels during admission have been shown to have prognostic value in the diagnosis of heart failure and further predict the in-hospital mortality of acute decompensated heart failure (ADHF). This study describes the characteristics of BNP among hospitalized ADHF and elucidates its prognostic value of in-hospital mortality in an Asian population.MethodsWe consecutively studied patients aged 20+ who were discharged with a diagnosis of ADHF from March 2013 to March 2014 in a tertiary hospital of northern Taiwan by reviewing medical records. Prognostic predictors of mortality were assessed using Cox proportional hazard regression models. BNP > 100 pg/ml was used as the cut-off for defining abnormally high BNP based on current clinical practice criteria.ResultsAfter implementation of our exclusion criteria, a total of 1,807 patients hospitalized with ADHF were studied. Compared to those subjects with BNP ≤100 pg/ml, individuals with higher BNP tended to have more advanced age, more clusters of the typical signs of heart failure (HF) (e.g., peripheral edema or lung rales) at presentation, lower ejection fraction, lower hemoglobin levels, more disturbed biochemical data, worsened renal function, and twice the risk for in-hospital mortality (15.2 vs 6.2 %, all p < 0.05). In a multivariate analysis, more advanced age, the presence of rales, a worse New York Heart Association functional class, wider QRS duration, and abnormal BNP levels (>100 pg/ml) were all associated with in-hospital mortality among admitted HF patients after accounting for clinical co-variates and global ventricular ejection fraction (HR: 2.17, 95 % CI: 1.15–6.64, p = 0.024).ConclusionAbnormally high BNP levels in ADHF patients during admission were tightly linked to clinical features of worse physical, functional, and clinical presentations, and further provided prognostic value for determining in-hospital mortality among patients with ADHF in an Asian population.
