Patients with diabetes also had significantly higher levels of cardiac injury biomarkers, including troponin T (TnT) (median [IQR], 0.013[0.009-0.032] vs. 0.008 [0.006-0.013] ng/mL; p < 0.0001), creatine kinase-myocardial band (CK-MB) test (median [IQR], 1.73 [0.97-3.51] vs. 1.19 [0.76-2.22] ng/mL; p = 0.0050), myoglobin (median [IQR], 49.6 [27.2-146.5] vs. 42.5 [26.2-76.1] ng/mL; p = 0.0121), and N-terminal pro-brain natriuretic peptide (NT-proBNP) (median [IQR], 271.9 [99.8-618.0] vs. 134.9 [48.6-422.9] pg/mL; p = 0.0037). This evidence concerns the gene NPPB and diabetes mellitus.
