    Twenty patients receiving long term diuretic treatment for arterial hypertension (18 patients) or congestive heart failure (two patients) received magnesium supplementation as aspartate hydrochloride 15 mmol/day for six months. Both systolic and diastolic pressures decreased significantly, by a mean of 12/8 mm Hg. No significant changes were recorded in plasma or urinary electrolytes except for magnesium, 24 hour urinary volumes, or body weight after treatment. The effect of magnesium on blood pressure may be direct or through influences on the internal balance of potassium, sodium, and calcium.
