The Effect of Atorvastatin on Endothelial Cell Dysfunction in Chronic Kidney Disease

June 3, 2014 updated by: Duke University
The purpose of this study is to see if patients with chronic kidney disease have endothelial cells that don't function properly, which is thought to be a marker for cardiovascular risk. Endothelial cells line the heart and blood vessels. The investigators will treat your high cholesterol with a cholesterol-lowering drug (atorvastatin, or Lipitor). They will determine if this cholesterol lowering drug improves subjects' cholesterol as well as the function of endothelial cells.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Atorvastatin
Subjects will be treated with atorvastatin 10 mg/day for 30 days. The study team will obtain one blood and urine sample at baseline prior to starting atorvastatin therapy, and again after 30 days of drug therapy. The study team will do ultrasound imaging of the arm in which a probe will be placed over the blood vessels to measure the diameter of the artery and how this changes after a blood pressure cuff is inflated and then deflated. Subjects will take one nitroglycerine tablet during the ultrasound imaging.
Drug: Atorvastatin
Other Names:
  • Lipitor
