Correction of endothelial dysfunction in hypertensive patients with type 2 diabetes mellitus during combined antihypertensive therapy
Abstract
AIM. To evaluate the impact of 6-month antihypertensive therapy with the combined drug amlodipine + lisinopril (ekvator) on endothelial dysfunction (ED) and carbohydrate metabolic parameters in patients with hypertension and type 2 diabetes mellitus (DM). MATERIALS AND METHODS. The investigation enrolled 30 patients aged 40-65 years with Stages II-III hypertension concurrent with type 2 DM. All the patients received combined antihypertensive therapy with amlodipine + lisinopril for 24 weeks. Endothelial function (EF) was studied from the serum and urine concentrations of the metabolites nitric oxide (NO) and endothelin-1 (ET-1) and from occlusion test RESULTS. Carbohydrate metabolic parameters were estimated. Insulin resistance (IR) was judged from basal insulin concentrations, followed by the calculations of the Homeostasis Model Assessment (HOMA) index. RESULTS. Following 24 weeks of therapy with amlodipine + lisinopril and close adherence to dietary recommendations, all the patients achieved the target levels of blood pressure and glycated hemoglobin (HbA1c). There was a significant improvement in EF in hypertensive patients with type 2 DM: NO production was increased in both the serum and urine (by 122.8 and 65.8%, respectively). ET-1 secretion was naturally decreased in both the serum and urine (by 26.1 and 76.1%, respectively; p
