Renal or renovascular hypertension.
Renovascular hypertension (high blood pressure) is hypertension which appears because one or both of the kidney arteries get narrow and it hinders the entry of blood to the kidneys. Blood flow became reduced and it causes the lowering of the blood pressure.
Kidneys produce hormones which keep salt and water. It makes blood pressure to get increased. There are a lot of illnesses that lead to the narrowing of the renal arteries. Renal artery stenosis is one of the most widespread illnesses.
There are no certain symptoms of renovascular hypertension. One of the possible symptoms is a mild headache. If you suffer from terrible headache or you observe the following symptoms you are expected to have malignant hypertension.
Its possible symptoms are:
* the feeling of tiredness
* confusion
* vision changes
* crushing, angina-like chest pain
* heart failure (flash pulmonary edema)
* blood in urine
* nosebleed
* irregular heartbeat
* noise in the ear or buzzing
* very high blood pressure
* kidney and renal failure
The possible symptoms of renovascular hypertension are:
1) very high blood pressure, which can hardly be controlled.
2) A noise which is observed when the doctor places a stethoscope over the abdominal area.
3) Flash pulmonary edema periodically occurred.
4) Quick development of kidney damage.
5) Sharp renal damage which is observed after the intake of ACE-I or ARB type medicines.
6) Hypertension which gets rapidly worse and which is observed among elderly people who had previously no problems with the control of their pressure.
Renovascular hypertension can be treated with medications which control blood pressure:
diuretics, beta blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers (ARBs) and alpha blockers.
Medications are prescribed individually. Medication and dosage should be prescribed individually. Blood pressure should be measured frequently. Sometimes with the removal of the cause the illness is treated.
The surgery of a damaged artery can be held to improve its condition. Fibromuscular dysplasia ( an vascular illness which leads to the narrowing of the renal arteries) is successfully treated with percutaneous transluminal renal angioplasty (PRTA).
