Objective   To determine the multiple functions of policosanol in elderly dyslipidemia patients. Methodology: There were 294 elderly dyslipidemia patients enrolled into this clinical study. They were randomly divided into four groups, as follows: 20 mg policosanol (group A, n = 64); 10 mg policosanol (group B, n = 72); 20 mg atorvastatin (group C, n = 91); and 10 mg policosanol + 20 mg atorvastatin (group D, n = 62). Plasma platelet count, platelet aggregation rate, circulating endothelial cell (CEC) count, high sensitivity C-reactive protein (hs-CRP), and carotid intima–media thickness (IMT) were measured before the study (week 0) and at weeks 12, 24, and 52.Results   In group A, the platelet aggregation rate caused by adenosine diphosphate (ADP) after treatment was significantly decreased compared with before treatment (48.79% ± 20.29% vs. 40.37% ± 23.56%), but the arachidonic acid (AA)-induced platelet aggregation rates were similar. The platelet aggregation rates induced by AA and ADP in groups B, C, and D did not change significantly. CEC counts and hs-CRP and homocysteine levels in all groups after treatment were significantly lower compared with before treatment, but carotid IMTs were similar.Conclusion   Policosanol regulates blood lipid levels and improves endothelial cell function, and it could delay the progress of atherosclerosis. Trial registration number: ChiCTR-RRC-17013396 (retrospectively registered).
