INS and myocardial ischemia: At the univariate analysis de novo IHD revealed significantly associated with higher levels of insulin (median 9.8 μU/mL vs 3.5 μU/mL; p = 0.008) and HOMA-IR (median 2.34 vs 0.74; p = 0.012), as well as higher glucose levels both at baseline and at 120 min (median 97 mg/dL vs 86.5 mg/dL; p = 0.038 and median 135 mg/dL vs 102.5 mg/dL; p = 0.045, respectively) and HbA1c levels (median 5.6% vs 5.2%; p = 0.001).
