BackgroundNeuregulin-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 MethodsIn 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.ResultWhen 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 (β =  - 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.ConclusionsWe 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.© 2024.
