Why the study?
Does restoration of a low-salt diet reverse impaired skeletal muscle arteriolar vasodilator reactivity induced by a high-salt diet and reduced renal mass hypertension in rats?

Comparison
High-salt diet for 4 weeks followed by low-salt… vs Continuous low-salt diet or continuous high-salt…
Design
Preclinical
Follow-up

Suggests dietary correction normalizes vasodilator reactivity absent structural hypertension; leaves open mechanisms of incomplete recovery in reduced renal mass models.
Does restoration of a low-salt diet reverse impaired skeletal muscle arteriolar vasodilator reactivity induced by a high-salt diet and reduced renal mass hypertension in rats?
Impaired vascular reactivity from a high-salt diet is fully reversible with dietary correction, but recovery is delayed or incomplete when structural hypertension (RRMHT) is present.
Frisbee et al. (1999) studied this question.
