High dietary salt intake in hypertensives, relatives of patients with stroke and in university students. The drama of a country with rate of mortality by stroke

renin, correlated inversely with systolic and diastolic salt sensitivity (R -0.44, P 0.008 and R -0.39, P 0.02, respectively). These data suggest that salt reduction with 100 mmol (6 grams) per day induces blood pressure reductions comparable to pharmacological antihypertensive mono-therapy in subjects with normal or slightly elevated blood pressure. Initial P-renin, with subjects on their habitual diet, correlated inversely with salt sensitivity and could thus be useful to identify individuals with the greatest blood pressure lowering benefit from reduced salt intake.
