ABSTRACT
BACKGROUND: Neuregulin-1(NRG-1) is a protein that belongs to the group of epidermal growth factors. It plays vital roles in anti-fibrotic effects on the myocardium. The current paper explores the role of NRG-1 in type 2 diabetes mellitus (T2DM) and its relation to atherogenic index as a factor for increasing cardiovascular disease(CVD) risk. MATERIAL AND METHODS: In this study, 79 diabetes mellitus patients are independent insulin. These patients consisted of 53 females and 26 males their age were ranged 40-67 years. They were divided into two groups depending on the atherogenic index of plasma (AIP). Group I including48 diabetic patient with high risk of CVD and group II including 31 diabetic patients without risk CVD. Forty healthy individuals were included as control. RESULT: When compared to the control group, the serum levels of NRG-1 were significantly lower (p = 0.01). Additionally, group I had a much lower NRG-1level than group II. The results of multiple stepwise regression showed that the only independent predictor for NRG-1 level prediction was AIP (ß = - 0.600, P = 0.040). When comparing the diabetic patients with high risk factors for CVD to the healthy subject group, the AUC was outstanding (AUC = 0.889, P = 0.001) and had a high diagnosis. CONCLUSIONS: We proved low NRG-1 levels in diabetic patients and the association of highest NRG-1 amounts to a better AIP. Moreover, the measurement of NRG-1 levels could be beneficial as laboratory markers to monitor for increasing CVD risk in type 2 diabetes mellitus.
