*inability to excrete sodium and fluid leading to volume expansion
*altered secretion of rennin angiotensin with change in vascular tone
Renal hypertension is further divided into renovascular hypertension and renal parenchymal hypertension.
CKD or renal parenchymal disease is the most common form of secondary hypertension. Hypertension occurs in more than 80% of patients with chronic renal failure and is a major factor causing their increased CV morbidity and mortality seen in CKD.
Parenchymal disease ultimately decreases the glomerular filtration rate and thereby increases blood pressure by hindering the excretion of salt and excess fluid.
In patients with mild or moderate renal insufficiency, stringent blood pressure control is imperative to reduce the progression to end-stage renal disease and to reduce the excessive CV risk associated with CKD.
