NPPB and diabetes mellitus: For multivariate analysis, the association of galectin-3 > 17.6 ng/mL and BNP > 500 pg/mL showed a significant correlation with a worse clinical prognosis, independent of renal function (OR 2.99, p = 0.025), LVEF (OR 2.98, p = 0.042), age (OR 3.56, p = 0.007), diabetes (OR 3.61, p = 0.009), and functional parameters measured with the Barthel Index (OR 5.43, p = 0.01).
