Circulating biomarkers are associated with cardiac structural and functional abnormalities in rheumatoid arthritis.Biomarkers like NT-proBNP and hs-TnT indicate myocardial stress and damage.Elevated left ventricular mass index (LVMi) and left atrial volume index (LAVi) predict higher cardiovascular event rates. Here, NPPB is linked to rheumatoid arthritis.
