Clinical and prognostic implications of hyaluronic acid in hospitalized patients with heart failure

AbstractWe investigated the clinical and prognostic implications of hyaluronic acid, a liver fibrosis marker, in patients with heart failure. We measured hyaluronic acid levels on admission in 655 hospitalized patients with heart failure between January 2015 and December 2019. Patients were stratified into three groups according to hyaluronic acid level: low (<  84.3 ng/mL,n = 219), middle (84.3–188.2 ng/mL,n = 218), and high (≥ 188.2 ng/mL,n = 218). The primary endpoint was all-cause death. The high hyaluronic acid group had higher N-terminal pro-brain-type natriuretic peptide levels, larger inferior vena cava, and shorter tricuspid annular plane systolic excursion than the other two groups. During the follow-up period (median 485  days), 132 all-cause deaths were observed: 27 (12.3%) in the low, 37 (17.0%) in the middle, and 68 (31.2%) in the high hyaluronic acid (P <  0.001) groups. Cox proportional hazards analysis revealed that higher log-transformed hyaluronic acid levels were significantly associated with all-cause death (hazard ratio, 1.38; 95% confidence interval, 1.15–1.66;P <  0.001). No significant interaction was observed between hyaluronic acid level and reduced/preserved left ventricular ejection fraction on all-cause death (P = 0.409). Hyaluronic acid provided additional prognostic predictability to pre-existing prognostic factors, including the fibrosis-4 index (continuous net reclassification improvement, 0.232;...
