NCT00427232

Brief Summary

Endothelin is a hormon that causes acute and chronic narrowing of heart vessels. The purpose of this study is to assess whether suppression of this activity by using two types of receptor antagonists can reduce this effect and thus improve blood supply of the heart muscle.
