最近的一些研究指出,在饮食中适当地限制钠盐对降低中等程度高血压患者的血压有效,严格限制钠盐对重度高血压的治疗也起作用。肾血管性高血压是一种肾素依赖型高血压。一般认为,无盐饮食可刺激肾素分泌从而升高血压,所以对肾血管性高血压病人限制钠盐是不利的。鉴于目前尚无有关限钠饮食对肾血管性高血压影响的临床研究报告,本文通过临床观察以评价低钠饮食对肾血管性高血压的影响。
Recent studies indicate that proper dietary restriction of sodium is effective in reducing blood pressure in patients with moderate hypertension and that restricting the use of sodium in the treatment of severe hypertension also works. Renovascular hypertension is a renin-dependent hypertension. Is generally believed that salt-free diet can stimulate the secretion of renin so as to increase blood pressure, so the limit of sodium in patients with renal vascular hypertension is unfavorable. In view of the fact that there is no clinical study on the effect of sodium restriction on renovascular hypertension, we evaluate the effect of hyponatremia on renovascular hypertension through clinical observation.
