Effects of Aliskiren, Ramipril, and the Combination on Levels of Angiotensin II in Patients With Decompensated Systolic Heart Failure
Summary
In addition to the blood pressure lowering effects of aliskiren, it may have beneficial effects on blocking the so called RAAS (renin-angiotensin-aldosterone system) at the tissue level. An increase of angiotensin II is associated with progression of heart failure. Although the use of ACE-inhibitors in heart failure shows clinical benefit, an increase in angiotensin II due to an angiotensin II "escape" phenomenon is not desirable. It is not yet known if a direct renin inhibitor can reduce or even prevent the angiotensin II escape phenomenon associated with the use of an ACE-inhibitor. Therefore the study tested the effects of ramipril, aliskiren and the combination of both on levels of angiotensin II in the blood in patients with systolic heart failure
