[Salt-induced inappropriate augmentation of intrarenal RAAS and its treatment in patients with chronic kidney disease].

Focus on the role of the renin-angiotensin-aldosterone system (RAAS) in the pathophysiology of hypertension and renal damage has shifted recently to the role of the local RAAS in the kidneys. Inappropriate augmentation of intrarenal RAAS activity in patients with chronic kidney disease has suggested playing important roles in the development of hypertension and renal injury. In this article, I show the recent findings that salt-induced this augmentation may contribute to the development of salt-sensitive hypertension and play a key role in cardiorenal syndrome (CRS), and that blockade of intrarenal RAAS may be an important strategy for salt-sensitive hypertension and CRS.
