Reno vascular hypertension

by

Q) Which of the following is true about reno vascular hypertension

a) Seen in young age group

b) Both kidneys are of same size

c) It is familial

d) Diuretics will control the hypertension

a

Renal artery occlusion creates ischemia of the kidney which releases renin. Hypereninemia leads to secondary hypertension. This further leads to conversion of angiotensin I to angiotensin II and vasocontriction and eventually release of aldosterone.

It is a disease of young adults and children

Size of the kidneys vary and diuretics do not control hypertension because the mechanism is high renin secretion which is unresponsive to diuretics.
