There was a significant difference in mean fasting blood insulin (p < 0.01), syntax score (p < 0.01), duration of diabetes (p = 0.007), fasting blood glucose (p = 0.001), body mass index (p = 0.023) and left ventricular ejection fraction (p = 0.015) in those who suffered MACE when compared who did not have MACE (Table 1). This evidence concerns the gene INS and diabetes mellitus.
