The "gold standard" for the assessment of salt sensitivity of hypertension is the blood pressure response to dietary NaCl restriction; nevertheless, for practical purposes, a more rapid test that would not depend on the patient's compliance to the dietary prescription would be very useful in clinical research and medical practice. The aim of this study was thus to evaluate the effectiveness and reliability of a rapid, easy-to-standardize protocol for the assessment of salt sensitivity against the blood pressure response to dietary salt restriction. A total of 108 hypertensive patients were screened for salt sensitivity by the modified protocol of Grim et al. Thereafter, nine patients identified by the test as salt sensitive and nine identified as salt resistant followed, for two consecutive periods of 1 week, a diet with normal (200 mmol/day) or low (50 mmol/day) NaCl content. Compliance to the diet was checked by repeated 24-h urine collections. The group as a whole experienced a significant fall in blood pressure during the low Na diet (mean pressure = 123 +/- 3 v 118 +/- 3 mm Hg; P &lt; .05). However, whereas patients identified as salt sensitive by the Grim protocol had a marked and significant blood pressure decrease (systolic -12 mm Hg, diastolic -7 mm Hg), no change was observed in those classified as salt resistant (systolic -2 mm Hg, diastolic -2 mm Hg). A significant correlation between changes in urinary Na excretion and changes in blood pressure was found only in salt-sensitive hypertensive patients. In conclusion, the modified Grim protocol tested in this study was able to correctly predict a significant blood pressure response to dietary salt restriction in the majority of cases. A validation of this test in a larger patient population may be advisable.
