How to lower the damage to the hypertensive nephropathy
It is hot in
summer, so the vessels will be dilation. Peripheral vascular resistance
decreases, then the blood volume decreases through sweating, leading to
reduction in blood pressure. As a result, the renal perfusion reduces,
renal becomes ischemia, hypoxia which exacerbates the damage to kidney.
Therefore, if without timely blood pressure regulation, the renal perfusion will reduce more.
Generally, the blood pressure is
the highest in the morning, then gradually decrease, which reaches the
slowest in the evening. But the hot weather would cause dysfunction of
autonomic nerve: blood pressure rises during night,especially for
nephropathy patients. About 74%-82% of kidney patients’ blood pressure
would not decrease at night.
So the high temperature season, kidney
patients have High blood pressure fluctuations, prone to cardiovascular
and cerebrovascular accidents, aggravating kidney damage, which needs to
adjust the medication time.
Don't pursue a severe blood pressure decrease.
When the proteinuria+ is less than 1.0g/d, the blood pressure should decrease to 130/80mmHg.
When it is higher than 1.0g/d, the blood pressure should decrease to 125/75mmHg.
