Introduction
The purpose of the CORAL study is to determine the best treatment for patients who have high blood pressure and blockage of the renal artery that supplies blood to the kidney.
This blockage is caused by the build up of plaque inside the renal artery. The blockage causes decreased blood pressure in the kidney which releases chemicals into the body to increase blood pressure. As a patient in the study there are 2 courses of treatment. One group will receive blood pressure medication only.
The second group will receive blood pressure medication plus a surgically placed stent, which is used to open the blockage. Currently, there is no agreement on which method of treatment is best. The CORAL study will determine the safest and most effective method for treating renal artery stenosis.
