Background: An elevated pulmonary artery wedge pressure (PAWP), a surrogate of left ventricular filling pressure, is associated with poor outcomes in patients with heart failure (HF). In addition, obesity paradox is well recognized in HF patients and body mass index (BMI) also provides a prognostic information. However, there is little information available on the prognostic value of the combination of the echocardiographic derived PAWP and BMI in patients with HF with preserved ejection fraction (HFpEF). Methods and Results: Patients data were extracted from The Prospective mUlticenteR obServational stUdy of patIenTs with Heart Failure with Preserved Ejection Fraction (PURSUIT HFpEF) study, which is a prospective multicenter observational registry for acute decompensated heart failure (ADHF) patients with HFpEF. We analyzed 548 patients after exclusion of patients undergoing hemodialysis, patients with in-hospital death, missing follow-up data, or missing data to calculate PAWP or BMI. Body weight measurement and echocardiography were performed just before discharge. PAWP was calculated using the Nagueh formula [PAWP = 1.24* (E/e’) + 1.9] with e’ = [(e’ septal + e’ lateral ) /2]. During a mean follow up period of 1.5±0.8 years, 86 patients had all-cause death (ACD). Multivariate Cox analysis showed that both PAWP (p=0.020) and BMI (p=0.0001) were significantly associated with ACD, independently of age and previous history of HF hospitalization, after the adjustment with gender, left ventricular ejection fraction, NT-proBNP and estimated glomerular filtration rate. Kaplan-Meier curve analysis revealed that there was a significant difference in the risk of ACD when patients were stratified into 3 groups based on the median values of PAWP (17.3) and BMI (21.4). Conclusions: The combination of the echocardiographic derived PAWP and BMI might be useful for stratifying ADHF patients with HFpEF at risk for the total mortality.

Introduction: Changes in N-terminal pro brain natriuretic peptide (NT-proBNP) have been demonstrated to correlate with outcomes in patients with heart failure (HF) and reduced ejection fraction (EF). However the prognostic value of a change in NT-proBNP in patients with heart failure and preserved ejection fraction (HFPEF) is unknown. Hypothesis: To assess the impact of changes in NT-proBNP on all-cause mortality, HF hospitalization and their composite in an unselected population of patients with HFPEF. Methods: 643 outpatients (age 72+12 years; 41% females) with HFPEF (ejection fraction ≥40%) enrolled in the Swedish Heart Failure Registry between 2005 and 2012 and reporting NT-proBNP levels assessment at initial registration and at follow-up were prospectively studied. Patients were divided into 2 groups according the median value of NT-proBNP absolute change that was 0 pg/ml. Median follow-up from first measurement was 2.25 years (IQR: 1.43 to 3.81). Adjusted Cox’s regression models were performed using total mortality, HF hospitalization (with censoring at death) and their composite as outcomes. Results: After adjustments for 19 baseline variables including baseline NT-proBNP, as compared with an increase in NT-proBNP levels at 6 months (NT-proBNP change>0 pg/ml), a reduction in NT-proBNP levels (NT-proBNP change<0 pg/ml) was associated with a 45.2% reduction in risk of all-cause death (HR: 0.548; 95% CI: 0.378 to 0.796; p:0.002), a 50.1% reduction in risk of HF hospitalization (HR: 0.49; 95% CI: 0.362 to 0.689; p<0.001) and a 42.6% reduction in risk of the composite outcome (HR: 0.574; 95% CI: 0.435 to 0.758; p<0.001)(Figure). Conclusions: Reductions in NT-proBNP levels over time are independently associated with an improved prognosis in HFPEF patients. Changes in NT-proBNP could represent a surrogate outcome in phase 2 HFPEF trials.

Backgrounds: Although B-type natriuretic peptide (BNP) and N-terminal pro B-type natriuretic peptide (NT-proBNP ) are interrelated parameters in assessment heart failure severity and prognosis, the ratio of NT-proBNP to BNP (NT-proBNP/BNP) are affected by various clinical factors, such as renal function. However, little is known about the influence of inflammation on NT-proBNP/BNP in patients with heart failure and preserved ejection fraction (HFpEF). Methods and Results: Patients data were extracted from PURSUIT-HFpEF registry, which is a multicenter prospective observational study including patients hospitalized for acute heart failure with left ventricular ejection fraction of >50%. Of 871 patients, data of BNP and NT-proBNP was available in 654 patients. The median baseline concentration of BNP was 474 pg/ml (299-720), NT-proBNP was 3310 pg/ml (1740-6840), and NT-proBNP/BNP was 7.6 (5.0-11.8). In multivariable linear regression analyses, older age [odds ratio (OR); 1.05, 95% confidence interval (CI); 1.02-1.09, p=0.001], higher creatinine [OR; 2.63, 95% CI; 1.66-4.16, p<0.001], and higher C-reactive protein (CRP) [OR; 1.17, 95% CI; 1.06-1.28, p<0.001] were significantly associated with a higher NT-proBNP/BNP (>median value of 7.6). However, other factors expected to affect NT-proBNP/BNP, such as atrial fibrillation and body mass index, were not associated with a higher NT-proBNP/BNP in this study. Patients in the highest CRP quartile had significantly higher NT-proBNP/BNP than those with other quartiles. Conclusion: In HFpEF patients, concomitant inflammation was associated with high NT-proBNP/BNP, which indicated that we need a careful interpretation on these two natriuretic peptides of patients with HFpEF and inflammatory status, such as infection.
