Abstract P276: Discordance Between Changes in NT-proBNP and Cardiac Function Following Bariatric Surgery

Background: The N-Terminal of pro-B-type natriuretic peptide (NT-proBNP) is a potent biomarker for heart failure (HF), reflecting left ventricular dilation and stress. The association among obesity, HF, and NT-proBNP is complex, with paradoxically lower levels of NT-proBNP in obese individuals, despite their elevated HF risk. Furthermore, a few studies have reported decreased HF risk, but also increases in NT-proBNP, after weight loss via...
