Association of B-Type Natriuretic Peptide With Intrinsic Capacity Trajectories Among Chinese Older Adults.
BACKGROUND Intrinsic capacity (IC) is central to healthy aging, yet accessible and cost-effective biomarkers for identifying individuals at risk of IC decline remain limited. We investigated whether elevated B-type natriuretic peptide (BNP), including persistent BNP abnormalities, is associated with baseline IC and lon...
