Patients with diabetes had higher creatinine (96 [81–118] vs. 91 [77–105] μmol/L, p = 0.02) and elevated cardiac biomarkers: NT-proBNP (1091 [326–2272] vs. 579 [232–1136] pg/mL, p < 0.001), hs-TnT (27 [14-41] versus 15 [9-22] ng/L, p < 0.001), GDF-15 (2412 [1603–3331] versus 1039 [753–1470] pg/mL, p < 0.001), sST2 (28 [9-22] versus 26 [21-32] ng/mL, p = 0.038), and Gal-3 (10.0 [8.0–12.0] versus 8.0 [7.0–10.0] ng/mL, p < 0.001). This evidence concerns the gene LGALS3 and diabetes mellitus.
