5. Study Description
Brief Summary
The management of patients with resistant arterial hypertension, who are characterized by a very high cardiovascular risk, remains a major therapeutic issue. The use of endothelin-1 (ET-1) receptor antagonists, in addition to lowering blood pressure, may also improve endothelial function in these patients. The objective of this study is to assess the vascular impact of an ET-1 receptor antagonist on vascular function and systemic and central hemodynamics in patients with resistant arterial hypertension and ensure their good renal tolerance.
