NCT01099865
The UKPDS risk score is recommended to assess global risk for future coronary heart disease (CHD) events in primary prevention. Recently, high-sensitivity C-reactive protein (hsCRP) has emerged as a strong independent risk factor for CHD. 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) is a promising imaging technique for the evaluation of vascular inflammation that reflects vulnerable atherosclerotic plaque.
NCT00968006
Endothelial progenitor cells (EPCs) are involved in cardiovascular homeostasis, through angiogenesis and endothelial healing. Diabetic patients have a high risk of cardiovascular events and low levels of circulating EPCs. Sitagliptin is an oral DPP-IV antagonist, approved for the treatment of type 2 diabetes. It increases the bioavailability of endogenous incretins, thus improving insulin and glucagon secretion. SDF-1, one of the major EPC regulators, is also a substrate of DPP-IV. This study tests the hypothesis that sitagliptin increases the levels of circulating EPCs in type 2 diabetic patients.
NCT01096277
Glucagon-like peptide 1 (GLP-1) is a 30-amino acid gut hormone secreted in a nutrient-dependent manner that stimulates insulin secretion and inhibits glucagon secretion and gastric emptying, thereby reducing postprandial glycemia.1,2 GLP-1 is derived from posttranslational proteolysis of preproglucagon, and its peptide sequence is identical in mouse, rat, and human.2,3 After secretion from enteroendocrine L cells, GLP-1(7-36) amide is rapidly degraded by dipeptidyl peptidase-4 (DPP-4) to its N-terminally truncated metabolite GLP-1(9-36), which does not interact with the known GLP-1 receptor.4,5 The diverse actions of GLP-1 include the proliferation, differentiation, and protection from apoptosis of pancreatic β cells and the induction of satiety. GLP-1 also improves memory and learning, stimulates afferent sensory nerves, and has neuroprotective functions.1,6 Furthermore, GLP-1 receptor agonists have been reported to have cardiac and vascular actions in rodents and humans that include effects on contractility, blood pressure, cardiac output,7-10 and cardioprotection.11-14
