100 selected elderly patients with endothelial dysfunction were randomized to two groups,Group1:received policosanol 20mg qd;Group2:received placebo 20mg qd；endothelial function was tested by peripheral arterial tonometry(PAT) before and after 6 months' treatment with policosanol or placebo respectively; Endothelial dysfunction is defined as reactive hyperemia index(RHI)< 1.67; The aim of this study is to assess the clinical efficacy and safety of policosanol on elderly patients with endothelial dysfunction.
