Reproducibility of salt sensitivity testing using a dietary approach in essential hypertension (original) (raw)

To investigate the reproducibility of salt sensitivity testing using a dietary approach, 30 essential hypertensive patients underwent salt sensitivity testing on an outpatient basis twice with a 6 month interval. At both tests casual and 24-h ambulatory blood pressure (24-h BP) was recorded on habitual diet, then after a 6-day period on a low salt diet (aiming at 50 mmol/day), and finally after a 6-day period on a high salt diet (supplementation with sodium chloride tablets aiming at 250 mmol/day).
