Renin Angiotensin Aldosterone System Inhibitors in Chronic Kidney Disease: A Difficult Equation.

Chronic kidney disease (CKD) is a global health problem and is strongly associated with hypertension (HTN) and impaired quality of life. Managing HTN with agents that block the renin angiotensin aldosterone system (RAAS) remains the gold standard, however there is a misleading impression that patients with impaired renal function or those receiving hemodialysis should not be treated with RAAS inhibitors. To date, only a few data in this field are available, given that this population subset is systematically excluded from many major clinical trials. The purpose of this review was to solve the difficult equation regarding the optimal use of RAAS blockade in patients with CKD.
