Angiotensin II Receptor Blockade Physiological and Clinical Implications

The relationship between angiotensin II and hypertension was established in 1898 when angiotensin II was shown to modulate systemic blood pressure. Over the intervening decades, a complete characterization of the renin-angiotensin system (RAS) has been achieved, and our understanding of its biochemistry and physiology has led to the directed development of agents such as ACE inhibitors and receptor antagonists capable of controlling hypertension. More recently, it was shown that angiotensin II is secreted within certain tissues, and that these tissue-specific systems operate independently of the systemic RAS. The novel concept that angiotensin II regulates a number of cardiovascular processes that are unrelated to blood pressure has renewed the interest of both basic and clinical scientists in angiotensin II. The association between angiotensin II and cardiac growth, in particular, has indicated that therapies in use for hypertension may have direct application to the treatment of heart failure. This book focuses on developments in the molecular biology, cellular physiology and structure-function relationships of angiotensin II and its receptors.In addition, this volume covers the therapeutic uses for angiotensin receptor antagonists and considers their potential future applications. This volume aims to be a valuable resource for scientists, practising clinicians and students who are attempting to extend their knowledge in the field of hypertension and heart failure, and who are devoted to improving cardiovascular health.
