Cardiac deaths occurred in 285 patients (60% of deaths): 181 patients (22.6%) without DM, 62 diabetic patients (27.9%) on oral antidiabetic drugs and 42 diabetic patients (40.1%) on insulin therapy (HR = 1.44 [1.07–1.92] for the group with DM on oral antidiabetic drugs vs. the group without DM; HR = 2.65 [1.90–3.70] for the group with DM on insulin therapy vs. the group without DM and HR = 1.85 [1.24–2.74] for the group with DM on insulin therapy vs. the group with DM on oral antidiabetic drugs; Table 3 and Figure 1). Here, INS is linked to diabetes mellitus.
