Correlation of Endothelial Function and Early Coronary Artery Disease in Humans

Endothelial Dysfunction Clinical Trial

Official title:
Endothelin in the Coronary Circulation in Early Atherosclerosis in Humans

Clinical Trial Summary

Qualifying patients who are scheduled for angiogram with endothelial function testing are approached to participate in this protocol (consent form reviewed with patient). Those who are willing to participate will have additional measurements taken during their angiogram as part of this protocol. Patients who are diagnosed with Endothelial Dysfunction as a result of a clinically indicated angiogram will be eligible to participate in a 6 month medication trial (Atrasentan vs. placebo - randomized, blinded trial). Patients are monitored closely during the 6 month trial via phone calls and blood testing for assessment. At the end of the 6 months they return to Mayo for a repeat angiogram to assess endothelial function for any changes or improvements.

Clinical Trial Description

Aim I: To determine the activity of the endogenous endothelin system in the coronary circulation in humans with coronary endothelial dysfunction and atherosclerosis risk factors. Aim II: To assess the potential of chronic endothelin receptor antagonists to improve preexisting coronary endothelial dysfunction and myocardial perfusion in humans and Aim III: To assess the effect of chronic endothelin receptor antagonism on the endogenous nitric oxide system in association with oxidative stress in humans with early coronary disease risk factors. ;

Study Design

Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment
