Brief Summary
The diabetic dyslipidemia is one of the most important risk factor in the development of coronary artery disease. The low density lipoprotein (LDL)-like nanoemulsions is being used to study the clearance of cholesteryl ester and free cholesterol from intravascular in patients with advanced coronary artery disease and it was shown a higher removal of free cholesterol and higher deposit in vases of this patients. The aim of this study is to analyze the plasma kinetics of both forms of cholesterol(free ad esterified) in type 2 diabetes patients without a previous history of cardiovascular disease.

Interventions
this study is done with the injection of LDL-like nanoemulsion doubly labeled with 14C- cholesteryl oleate and 3H- cholesterol, with a total radioactivity injection dose of 0.03mSV. Blood sample collected in a pre established period of time in 24 hours.
