Abstract:
Objective: To explore influence of abnormal glucose metabolism on vascular endothelial injury in patients with essential hypertension (EH). Methods: A total of 46 pure EH patients (EH group) and 33 EH patients complicated type 2 diabetes mellitus (T2DM, EH + T2DM group) were enrolled. Blood glucose, blood lipid, body mass index (BMI), serum concentrations of homocysteine (Hcy) and urine microalbumin were measured and compared between two groups. Relationship among serum Hcy, urine microalbumin concentrations and blood glucose, blood lipids, BMI were analyzed. Results: Compared with EH group, there were significant increase in levels of BMI, fasting blood glucose (FBG), 2h postprandial blood glucose (2hPBG), glycosylated hemoglobin (HbA1c), triglyceride (TG), low density lipoprotein-cholesterol (LDL-C) and apolipoprotein B (ApoB), (P<0.05 or <0.01), and even more significant increase in serum levels of Hcy [(12.78±2.51) μmol/L vs. (16.26±2.91) μmol/L] and urine microalbumin [(19.45±5.24) mg/L vs. (33.65±10.70) mg/L] in EH + T2DM group, P<0.01 both; Pearson correlation analysis indicated that in EH patients with DM, serum Hcy level was positively correlated with BMI, FBG, HbA1c, LDL-C, ApoB and urine microalbumin (r=0.667~0.906，P<0.01 all), while urine microalbumin level was positively correlated with BMI, HbA1c, LDL-C, ApoB and serum Hcy (r=0.566~0.685, P<0.01 all). Conclusion: Abnormal glucose metabolism can aggravate both vascular endothelial injury and renal microvascular injury in patients with essential hypertension, and these are closely related with degree of abnormal glucose metabolism. Therefore, controlling blood glucose level can relieve vascular injury, further relieve pathological development of cardiovascular diseases as well as renal complications.
