ObjectivesTo observe the clinical significance of N-terminal natriuretic peptide combined with inflammatory factors, oxidative stress factors and blood lipid detection in elderly patients with Type-2 diabetes complicated with CHD (CHD), and provide a theoretical basis for the diagnosis and treatment of elderly patients with Type-2 diabetes complicated with CHD.MethodsA total of 40 patients with Type-2 diabetes complicated with CHD admitted to Affiliated Hospital of Hebei University from July 2019 and July 2020 were selected as the experimental group, and 40 patients with CHD who were hospitalized in our hospital during the same period without diabetes were selected as the control group. Venous blood was taken from all patients on morning and fasting basis, and their serum inflammatory factors as well as antioxidant molecules were examined respectively. Serum inflammatory factors include serum tumor necrosis factor α (TNF-A), interleukin-6 (IL-6), and C-reactive protein. Antioxidant molecules include antioxidant molecules superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), total antioxidant capacity (TAC), catalase (CAT), glutathione reductase (GR), N-terminal natriuretic peptide (NT-proBNP), white blood cells (WBC), hemoglobin (HBG), albumin (ALB) and blood lipid levels. The differences of the above indexes between experimental group and control group were compared and analyzed.ResultsThe serum levels of TNF-a, CRP, and IL-6 in the experimental group were apparently higher than those in the control group, with a statistically significant difference (P=0.00); The levels of SOD, TAC and CAT in the experimental group were significantly lower than those in the control group, with a statistically significant difference (P=0.00); The level of NT-proBNP and WBC count in the experimental group were significantly higher than those in the control group, with a statistically significant difference (NT-proBNP, P=0.01; WBC, P=0.00). However, no statistically significant difference was observed in the levels of HBG and ALB between the two groups (P>0.05). The experimental group had significantly higher TC and TG levels than the control group, with statistically significant differences (TC, P=0.01; TG, P=0.02), but had a significantly lower HDL level than the control group, with a statistically significant difference (P=0.00).ConclusionElderly patients with Type-2 diabetes complicated with CHD showed systemic microinflammation, decreased antioxidant molecule content, as well as myocardial damage and abnormal lipid metabolism compared with patients with CHD alone. For this reason, attention should be paid to the above risk factors in clinical practice, and proactive prevention and treatment should be taken to reduce the probability of related complications.Copyright: © Pakistan Journal of Medical Sciences.
