Abstract
Natriuretic peptides may be associated with the complex interaction between malnutrition and fluid overload. This study assessed the relationship between N-terminal pro-B-type natriuretic peptide (NT-proBNP), body fluid composition, and quality of life (QOL) domains. A multicenter, cross-sectional study was conducted between 2019 and 2022. The QOL survey of 322 patients undergoing maintenance hemodialysis (227 men and 95 women; mean age, 65 ± 12 years) was conducted using the Kidney Disease QOL-Short Form v. 1.3. The patients in the higher NT-proBNP quartile group were older and had a longer dialysis vintage; lower body mass index, serum albumin, blood urea nitrogen, creatinine, sodium, uric acid, total cholesterol, triglycerides, and hemoglobin levels; lower geriatric nutritional risk index (GNRI), skeretal mascle mass index, and phase angle (PhA); and higher pre- and post-dialysis systolic blood pressure (BP), cardiothoracic index, and C-reactive protein (CRP) (p < 0.05). Multivariate analysis revealed that post-dialysis systolic BP, CRP, and GNRI or PhA were independently associated with NT-proBNP. The higher NT-proBNP group experienced muscle attenuation and/or inflammation and an enlarged left atrium. Consequently, the elevated NT-proBNP by such an imbalance in body fluid composition is associated with lower health-related QOL.
