What were the results of the Shanghai Trial of Nifedipine in the Elderly (STONE)?
The mean achieved BP was 147/85 mm Hg in the nifedipine group and 156/ 92 mm Hg in the placebo group and although there was no significant difference in all-cause mortality, there were reductions in the rates of stroke and severe arrythmia in the lower-BP nifedipine treated group.
