Treatment of hypertension

1. RENOVASCULAR HYPERTENSION
RENOVASCULAR HYPERTENSION IS HIGH BLOOD PRESSURE DUE TO NARROWING OF THE
ARTERIES THAT CARRY BLOOD TO THE KIDNEYS. THIS CONDITION IS ALSO CALLED RENAL
ARTERY STENOSIS.
CAUSES
RENAL ARTERY STENOSIS IS A NARROWING OR BLOCKAGE OF THE ARTERIES THAT SUPPLY
BLOOD TO THE KIDNEYS.
THE MOST COMMON CAUSE OF RENAL ARTERY STENOSIS IS A BLOCKAGE IN THE ARTERIES.
THIS PROBLEM MOST OFTEN OCCURS WHEN A STICKY, FATTY SUBSTANCE CALLED PLAQUE
BUILDS UP ON THE INNER LINING OF THE ARTERIES, CAUSING A CONDITION KNOWN AS
ATHEROSCLEROSIS.
WHEN THE ARTERIES THAT CARRY BLOOD TO YOUR KIDNEYS BECOME NARROW, LESS BLOOD
FLOWS TO THE KIDNEYS. THE KIDNEYS MISTAKENLY RESPOND AS IF YOUR BLOOD PRESSURE

2. • RISK FACTORS FOR ATHEROSCLEROSIS:
• HIGH BLOOD PRESSURE
• SMOKING
• DIABETES
• HIGH CHOLESTEROL
• HEAVY ALCOHOL USE
• COCAINE ABUSE
• INCREASING AGE
2- FIBROMUSCULAR DYSPLASIA IS ANOTHER CAUSE OF RENAL ARTERY STENOSIS. IT IS
TYPICALLY SEEN IN WOMEN UNDER AGE 50. IT TENDS TO RUN IN FAMILIES. THE CONDITION IS
CAUSED BY ABNORMAL GROWTH OF CELLS IN THE WALLS OF THE ARTERIES LEADING TO THE
KIDNEYS. THIS ALSO LEADS TO NARROWING OR BLOCKAGE OF THESE ARTERIES.

3. • PRIMARY ALDOSTERONISM (HYPERALDOSTERONISM)
• IS A CONDITION THAT OCCURS WHEN THE ADRENAL GLANDS PRODUCE TOO MUCH
ALDOSTERONE, THE HORMONE RESPONSIBLE FOR BALANCING POTASSIUM AND SODIUM
IN THE BODY.
• OVERPRODUCTION OF ALDOSTERONE CAUSES THE BODY TO RETAIN MORE SODIUM
AND LOSE POTASSIUM, WHICH LEADS TO ELEVATED BLOOD PRESSURE. PATIENTS WITH
THIS CONDITION ARE AT INCREASED RISK OF HEART DISEASE AND STROKE.
