NCT00306826

Brief Summary

In patients with impaired glucose tolerance (IGT), the researchers want to study the relative effects of pioglitazone, simvastatin, or the combination of both on:

  • intima media thickness (IMT) as an easily assessed marker of atherosclerosis
  • heart rate variability (HRV) as a marker of autonomic neuropathy
  • flow-mediated vasodilatation (FMD) of the brachial artery as a marker of endothelial function
  • vascular and metabolic lab parameters
