Cardiovascular and hormonal effects of salt restriction

	Normal salt n = 8	Low salt n = 9
MABP (mmHg)	93 ± 3	87 ± 4
HR (beats min−1)	75 ± 5	69 ± 4
RBF (ml min−1)	239 ± 26	246 ± 25
RVR (mmHg ml−1 min−1)	0.39 ± 0.05	0.38 ± 0.04
PRA ((ng AngI) ml−1 h−1)	1.60 ± 0.13	4.54 ± 1.33 *

Values are means ± s.e.m.

^*P < 0.05 vs. normal salt diet. MABP, mean arterial blood pressure; HR, heart rate; RBF, renal blood flow; RVR, renal vascular resistance; PRA, plasma renin activity; AngI, angiotensin I.
