Body Composition Measures and N-terminal pro-B-type Natriuretic Peptide (NT-pro-BNP) in US Adults.

ABSTRACT:

Background

The associations of N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) with dual energy x-ray absorptiometry (DEXA)-derived measures of body mass and composition are largely unknown.

Methods

We included participants aged ≥20 years from the 1999-2004 National Health and Nutrition Examination Survey with NT-pro-BNP and DEXA-derived body composition (fat and lean mass) measures. We used linear and logistic regression to characterize the associations of measures of body mass and composition (body mass index [BMI], waist circumference [WC], fat mass, and lean mass) with NT-pro-BNP, adjusting for cardiovascular risk factors.

Results

We conducted sex-specific analyses among 9134 adults without cardiovascular disease (mean age 44.4 years, 50.8% women, and 72% White adults). The adjusted mean NT-proBNP values were lowest in the highest quartiles of BMI, WC, fat mass, and lean mass. There were large adjusted absolute differences in NT-pro-BNP between the highest and lowest quartiles of DEXA-derived lean mass, -6.26 pg/mL (95% confidence interval [CI], -8.99 to -3.52) among men and -22.96 pg/mL (95% CI, -26.83 to -19.09) among women. Lean mass exhibited a strong inverse association with elevated NT-pro-BNP ≥ 81.4 pg/mL (highest quartile) - odds ratio (OR) 0.58 (95% CI, 0.39-0.86) in men and OR 0.59 (95% CI, 0.47-0.73) in women for highest lean mass quartile vs. lowest quartile. Further adjustment for fat mass, BMI, or WC did not appreciably alter the inverse association of lean mass with NT-pro-BNP.

Conclusions

In a national sample of US adults, lean mass was inversely associated with NT-pro-BNP.

Project description:AimsAvailable upper reference levels (URLs) in older adults for N-terminal pro brain natriuretic peptide (NT-proBNP), an established biomarker for heart failure, are mainly based on small samples. We aimed to identify NT-proBNP URL in a population-based reference sample of individuals aged ≥65 years.Methods and resultsWe analysed established NT-proBNP predictors using quantile regression among 2459 participants of two-independent population-based cohorts located in Germany, the Activity and Function in the Elderly Study (ActiFE, n = 1450) and the Study of Health in Pomerania (SHIP-TREND-0, n = 1009). Based on predictors a reference population of 441 subjects (ActiFE, n = 227; SHIP-TREND-0, n = 214) without history of diabetes, cardiovascular, or pulmonary diseases and with systolic blood pressure (BP) <140 mmHg, diastolic BP ≥60 and ≤90 mmHg, haemoglobin in men ≥14 and ≤18 g/dL and in women ≥12 and ≤16 g/dL, GFR ≥60 mL/min/1.73 m2 , CRP <5 mg/L, BMI ≥18 and ≤33 kg/m2 , and hs-cTnI <40 ng/L were built with NT-proBNP median levels and 97.5% quantiles reported stratified by sex and age. In a secondary analysis the URL among 97 SHIP-TREND-0 participants with a left ventricular ejection fraction (LVEF) ≥50 and no diastolic dysfunction were estimated. The median age in the identified reference sample was 70 years, with 41.9% and 40.2% male participants in ActiFE and SHIP-TREND-0, respectively. We observed an age-dependent increment of NT-proBNP levels with higher values in women compared to men. Notably, NT-proBNP levels were >125 ng/L in 165 participants (37.4%), with NT-proBNP URL (97.5% quantiles) equal to 663, 824, 592, and 697 ng/L in men, and 343, 463, 2641, 1276 ng/L in women for ages 65-69, 70-74, 75-79, and 80+ years, respectively. In the secondary analysis with a LVEF ≥50 and no diastolic dysfunction (35 men and 62 women) NT-proBNP levels >125 ng/L were still observed in 38 (39.2%) participants.ConclusionsThis reference sample of apparently healthy asymptomatic older adults showed an age-related increment of NT-proBNP levels with URL markedly higher than the European Society of Cardiology recommended cut-off of 125 ng/L for the diagnosis of heart failure in ambulatory settings. Identifying URL in those ≥80 years remains complex. Our results attempt to provide a frame for the further investigation of age-specific NT-proBNP cut-offs in older adults. Considering the demographic changes, further evaluation of NT-proBNP URL in larger samples of older adults followed by the validation of age-specific cut-off values for the identification of heart failure in those 65 years or older are urgently needed.

Project description:BackgroundNT-proBNP (N-terminal pro-B-type natriuretic peptide) levels are variably elevated in heart failure with preserved ejection fraction (HFpEF), even in the presence of increased left ventricular filling pressures. NT-proBNP levels are prognostic in HFpEF and have been used as an inclusion criterion for several recent randomized clinical trials. However, the underlying biologic differences between HFpEF participants with high and low NT-proBNP levels remain to be fully understood.MethodsWe measured 4928 proteins using an aptamer-based proteomic assay (SOMAScan) in available plasma samples from 2 cohorts: (1) Participants with HFpEF enrolled in the PHFS (Penn Heart Failure Study; n=253); (2) TOPCAT (Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist Trial) participants in the Americas (n=218). We assessed the relationship between SOMAScan-derived plasma NT-proBNP and levels of other proteins available in the SOMAScan assay version 4 using robust linear regression, with correction for multiple comparisons, followed by pathway analysis.ResultsNT-proBNP levels exhibited prominent proteome-wide associations in PHFS and TOPCAT cohorts. Proteins most strongly associated with NT-proBNP in both cohorts included SVEP1 (sushi, von Willebrand factor type-A, epidermal growth factor, and pentraxin domain containing 1; βTOPCAT=0.539; P<0.0001; βPHFS=0.516; P<0.0001) and ANGPT2 (angiopoietin 2; βTOPCAT=0.571; P<0.0001; βPHFS=0.459; P<0.0001). Canonical pathway analysis demonstrated consistent associations with multiple pathways related to fibrosis and inflammation. These included hepatic fibrosis and inhibition of matrix metalloproteases. Analyses using cut points corresponding to estimated quantitative concentrations of 360 pg/mL (and 480 pg/mL in atrial fibrillation) revealed similar proteomic associations.ConclusionsCirculating NT-proBNP levels exhibit prominent proteomic associations in HFpEF. Our findings suggest that higher NT-proBNP levels in HFpEF are a marker of fibrosis and inflammation. These findings will aid the interpretation of NT-proBNP levels in HFpEF and may guide the selection of participants in future HFpEF clinical trials.
