Renovascular Hypertension is also called 'Renal Hypertension'. It is a condition in which High blood pressure (greater than 130/80 mmHg) caused by narrowing of the arteries that carry blood to the kidneys. Narrowing or blockage of the arteries that supply blood to the kidneys is called 'Renal artery stenosis.
Renovascular hypertension (RVH) is the form of secondary hypertension. In this some people have hypertension due to sleep apnea, obesity, thyroid problem.
BASIC MECHANISM OF RENOVASCULAR HYPERTENSION
Renin Angiotensin system (RAS) or Renin–Angiotensin Aldosterone system (RAAS) is a hormone system that is involved in the regulation of the arterial blood pressure. When the renal blood flow reduced, then kidneys convert Prorenin (protein) into Renin. Renin breaks into small plasma protein known as Angiotensin II Angiotensin II stimulates the secretion of the hormone aldosterone from the adrenal cortex. If the RAAS is excessively active, blood volume increases resulting blood pressure becomes too high. There are many drugs that interrupt different steps in this system to lower blood pressure.
WHAT ARE THE CAUSES OF RENAL HYPERTENSION?
When the arteries which carry blood to your kidneys becomes narrow, less blood flows to the kidneys. It releases hormones that tell the body to hold on to more salt and water. This causes your blood pressure to rise.
The most common cause of renal hypertension is:
- Atherosclerosis (i.e. deposition of sticky, fatty substance called plaque on the inner lining of arteries.)
- Fibro muscular dysplasia (i.e. this condition is caused by abnormal growth of cells in the walls of the arteries. This also leads to narrowing or blockage of these arteries.)
SYMPTOMS OF RENAL HYPERTENSION
Symptoms of severely elevated blood pressure include:
- Headache
- Confusion
- Blurry or double vision
- Bloody (pink-colored) urine
- Nosebleed
DIAGNOSTIC TEST
There are many screening tool develop for Renovascular hypertension:
- Duplex ultrasonography
- Computed tomographic angiography
- Magnetic resonance angiography
