Salt-Sensitive Hypertension: Can We Convert Salt-Sensitive State to a Salt- Resistant One?

Effect of low salt diet on insulin resistance in salt-sensitive versus salt-resistant hypertension.

Accumulating evidence shows an increase in insulin resistance on salt restriction. We compared the effect of low salt diet on insulin resistance in salt-sensitive versus salt-resistant hypertensive subjects. We also evaluated the relationship between salt sensitivity of blood pressure and salt sensitivity of insulin resistance in a multivariate regression model. Studies were conducted after 1 w...

Salt-induced hypertension in Dahl salt-resistant and salt-sensitive rats with NOS II inhibition.

Although recent evidence suggests that reduced nitric oxide (NO) production may be involved in salt-induced hypertension, the specific NO synthase (NOS) responsible for the conveyance of salt sensitivity remains unknown. To determine the role of inducible NOS (NOS II) in salt-induced hypertension, we treated Dahl salt-resistant (DR) rats with the selective NOS II inhibitor 2-amino-5,6-dihydro-6...

Patients With Salt-Sensitive Hypertension

Twenty-two patients with normal plasma renln and essential hypertension were classified as "salt-sensitive" (SS) (n=9) or "non-salt-sensitive" (NSS) (n=13) from an increase in mean blood pressure with changes in sodium intake from 25 to 250 meq/day. With the high sodium diet, the SS patients gained more weight (/?<0.05), retained more sodium (/><0.05), and had a greater increase in cardiac outp...

Salt-Induced Hypertension in Dahl Salt-Sensitive Rats

Cardiac output, blood volume, total peripheral resistance, and renal blood flow were measured in awake salt-sensitive and salt-resistant Dahl rats on normal rat chow (1% NaCl) and on high salt (8% NaCl) diets. Rats were studied after 4, 8, and 46 weeks on a 1% NaCl diet and after 4 and 8 weeks on an 8% NaCl diet Salt-sensitive rats on 8% NaCl for 4 weeks developed systolic hypertension; by 8 we...
