While hs-cTnT levels were significantly associated with increased risk of ischemic events in DM patients (adjusted HR: 1.91, 95% CI: 1.19–3.09), CK-MB levels did not show a significant difference between DM and non-DM patients (adjusted HR: 1.04, 95% CI: 0.59–1.86 for DM patients with CK-MB ≥ 1 URL). Here, TNNT2 is linked to diabetes mellitus.
