Summary
Cardiovascular disease is a major public health problem in our country. Among the causes of cardiovascular diseases are High Blood Pressure (HBP) and Diabetes Mellitus (DM). Type 2 diabetes (DM2) is associated with a twofold risk of cardiovascular disease, and endothelial dysfunction is an early marker of vascular complications. There is evidence of action of glucagon-like peptide 1 (GLP-1) on endothelial cells and vascular smooth muscle. Vildagliptin is a drug used in the treatment of DM2 able to prolong the activity of GLP-1, improving glycemic control and endothelial function. Objectives: To evaluate the effect of vildagliptin on endothelial function in patients with DM2 and hypertension using the Endo-PAT 2000 device.
