Hypertension, renal hypertension symptoms also exists , not repeat them. Here
are just some of the special aspects of the performance of renal hypertension
make a profile .
Compared with the same level of essential hypertension, renal hypertension
essential hypertension compared with more progress to malignant hypertension ,
which occurs in approximately 2 -fold. Which , IgA nephropathy , especially
sclerosis , or hardening of IgA nephropathy secondary to malignant hypertension
, especially common. Also, comparison with primary malignant hypertension ,
renal parenchymal malignant hypertension worse prognosis , some authors
statistics , the former five-year kidney survival rate was 60%, while the latter
one and a half years renal survival is only 4 %.
Renal hypertension is often severe retinopathy , cardiovascular and
cerebrovascular complications occur more often . This is because in addition to
hypertension, other cardiovascular risk factors often compound the presence of
renal parenchymal disease, such as lipid metabolism disorder nephrotic syndrome
, and glucose metabolism during diabetic nephropathy , anemia, renal
insufficiency , and hyperuricemia disease, high homocysteine , uremic toxins,
metabolic acidosis , and micro- inflammatory state , these complex factors will
significantly increase the incidence of cardiovascular complications.
In this , the need to emphasize that especially affect renal hypertension and
chronic kidney disease on the basis of renal disease progression . Chronic renal
disease was before the glomerular arterioles diastolic state, the system is very
easy to pass the glomerular hypertension , resulting in glomerular hypertension,
high perfusion and high filtration, this "three high " that can accelerate the
remaining glomerulosclerosis ; Meanwhile , long-term high blood pressure can
lead to kidney arteriosclerosis , including hyaline afferent arterioles ,
interlobular artery and arcuate artery intimal thickening of the muscle , so
that small artery wall thickening luminal narrowing , secondary to renal
ischemia
Damage ( glomerular ischemic collapse was to ischemic sclerosis , tubular
atrophy and renal interstitial fibrosis ) . Therefore, renal hypertension is not
well controlled will significantly accelerate renal parenchymal disease
progression , creating a vicious cycle .
Urinary protein quantity glomerular disease , hypertension and kidney damage
effect is more obvious , because both effects overlay. Now known proteinuria,
especially in a large number of glomerular proteinuria can be caused by a high
pressure, high perfusion and high filtration promote glomerulosclerosis ; And,
filtered proteins ( including complement and growth factors , etc.) and in
combination with protein certain substances ( including lipid and iron, etc. )
after being tubular reabsorption , tubular cells can activate the release of
pathogenic factors ( such as transforming growth factor β , etc. ) to promote
renal interstitial fibrosis. Therefore, in patients with renal hypertension with
proteinuria , more should be strictly controlled hypertension.
