Six patients with angiographically proven renal artery stenosis were given a low salt diet, consisting of 10 mEq sodium per day for 4-6 days. Five patients showed a remarkable decrease in blood pressure (BP), from 169 +/- 12/107 +/- 4 to 131 +/- 12/84 +/- 5 mmHg, despite a rise in renin level. The decrease in BP was paralleled by a decrease in urinary sodium excretion. Restoration of the regular diet caused immediate elevation of blood pressure. We conclude that severe sodium restriction can reduce blood pressure in patients with renovascular hypertension.
六名经血管造影证实患有肾动脉狭窄的患者接受了低盐饮食，即每天摄入10毫当量钠，持续4 - 6天。五名患者的血压显著下降，从169±12/107±4毫米汞柱降至131±12/84±5毫米汞柱，尽管肾素水平有所升高。血压下降的同时，尿钠排泄也减少。恢复正常饮食后，血压立即升高。我们得出结论，严格限制钠摄入可降低肾血管性高血压患者的血压。
