This article emphasizes (1) the utility of routine measurement of pro-insulin to insulin ratio as a specific marker of insulin resistance and predictor of future T2DM, HT and CAD, (2) routine C-Peptide estimation to determine which T2DM needs insulin and to monitor the effect of newer drugs which promote beta cell regeneration, (3) routine estimation of adiponectin and TNF alpha and monitor response to thiozolidine drugs which increases adiponectin and decreases TNF alpha production by adipocytes, (4) crucial role of AMPK--Cellular energy sensor in mediating the beneficial effects of exercise as well as drugs (adiponectin, metformin) in T2DM, (5) Availability of glucogon suppressors will eliminate the need for giving insulin to T2 DM with normal C Pepetide levels which inevitably causes undesirable weight gain & hypoglycemia.

The aim of the present study was to determine whether the endothelial dysfunction associated with CAD (coronary artery disease) and T2D (Type 2 diabetes mellitus) is concomitant with elevated mtROS (mitochondrial reactive oxygen species) production in the endothelium and establish if this, in turn, regulates the activity of endothelial AMPK (AMP-activated protein kinase). We investigated endothelial function, mtROS production and AMPK activation in saphenous veins from patients with advanced CAD. Endothelium-dependent vasodilation was impaired in patients with CAD and T2D relative to those with CAD alone. Levels of mitochondrial H(2)O(2) and activity of AMPK were significantly elevated in primary HSVECs (human saphenous vein endothelial cells) from patients with CAD and T2D compared with those from patients with CAD alone. Incubation with the mitochondria-targeted antioxidant, MitoQ(10) significantly reduced AMPK activity in HSVECs from patients with CAD and T2D but not in cells from patients with CAD alone. Elevated mtROS production in the endothelium of patients with CAD and T2D increases AMPK activation, supporting a role for the kinase in defence against oxidative stress. Further investigation is required to determine whether pharmacological activators of AMPK will prove beneficial in the attenuation of endothelial dysfunction in patients with CAD and T2D.
