Aliskiren improves nitric oxide bioavailability and limits atherosclerosis.

Inhibition of the renin-angiotensin system (RAS), with angiotensin-converting enzyme inhibitor- (ACEI) and angiotensin receptor blocker (ARB)–based treatment approaches, has emerged as the cornerstone of contemporary cardiovascular risk reduction. These therapies offer robust reductions in cardiovascular mortality in patients postmyocardial infarction, those with systolic heart failure, and in high-risk patients with atherosclerosis. Furthermore, interruption of the RAS system has emerged as a critical modulator of normal and aberrant renal physiology, and interruption of RAS signaling is linked to improved renal structure and function.
