Role of angiotensin II in cardiovascular disease - Therapeutic implications of more than a century of research

More than a century of research on the renin-angiotensin system (RAS) has uncovered the widespread involvement of angiotensin II (Ang II) in the pathophysiology of cardiovascular diseases. A number of outcomes-based mega trials utilising hard clinical endpoints have revealed beneficial effects of angiotensin receptor antagonists (AIIAs/ARBs) in patients with hypertension, heart failure, diabetic nephropathy, and post-myocardial infarction (MI). The results of these studies not only emphasise the importance of Ang 11 in the pathophysiology of these diseases but have provided the basis for an evidence-based approach for the use of AIIAs in clinical practice. It is hoped that the next 100 years of research into the RAS will uncover hitherto unimaginable therapeutic opportunities.
