To the editor: In December 1985, McCarron and Morris (1) reported that calcium supplementation leads to a clinically significant lowering ( > 10 mm Hg) of blood pressure in a subset (44%) of hypertensive persons tested in a randomized, placebo, crossover trial. They proposed that impaired calcium metabolism is a critical factor in the pathogenesis of both human and experimental hypertension. In a previous issue of Annals (2), McCarron suggested that the elevated prevalence of hypertension in blacks may be calcium related, but there were too few black hypertensive persons in their recent sample to allow testing of this hypothesis.
