NCT00574665

Brief Summary

The purpose of this study is to learn more about why patients with diabetes have increased heart attacks, strokes and other illnesses due to blood clots causing blockage of a blood vessel. The proposed protocol will study the separate and combined effects of hyperglycemia and hyperinsulinemia on endothelial function and fibrinolytic balance in Type 2 DM. Our hypothesis is that hyperglycemia, rather than hyperinsulinemia, is responsible for the dysregulation of fibrinolytic balance in diabetics.
