Effects of Xuezhikang capsule on blood lipids, platelet activation and coagulation-fibrinolysis activity in patients with hyperlipidemia

Objective: To investigate the effects of Xuezhikang capsule (XZK) on blood lipids level, platelet activation and coagulation-fibrinolysis activity in patients with hyerlipidemia.Methods: Seventy-six patients of hyperlipidemia were randomly divided into two groups, the XZK group (n = 38) treated with XZK 600mg, taken two times per day and the Simvastatin (SIM) group (n = 38) treated with SIM 20mg per day, with the treatment lasting 8 weeks for both groups. Levels of fasting serum lipids, including total cholesterol (TC), triglyceride (TG), high and low density lipoprotein cholesterol (HDL-C and LDL-C), plasma GMP-140, fibrinogen (FIB), tissue plasminogen activator (t-PA), plasminogen activator inhibitor type-1 (PAI-) and prothrombin time (PT) were all measured before and 8 weeks after treatment. Data were compared before and after treatment and also compared with those measured in 20 healthy subjects of control.Results: Before treantment the levels of TC, TG and LDL-C were obviously higher and HDL-C level was significantly lower in hyperlipidemia patients than those in healthy subjects (P<0.05 orP<0.01). After 4–8 weeks of XZK treatment, the levels of TC, TG, LDL-C and FIB and activities of GMP-140 and PAI-1 were obviously lowered (P<0.05 orP<0.01). But in the SIM group there was no obvious change in FIB (P>0.05), instead it showed obvious increase of HDL-C and decrease of TC and LDL-C after treatment (P<0.05 orP<0.01).Conclusion: XZK could inhibit platelet activity and improve coagulation-fibrinolysis function, besides its lipids lowering effect.
