Abstract:
Objective:To explore influence of probucol combined atorvastatin on blood viscosity ,transcranial Doppler (TCD) indexes and carotid plaque stability in patients with large artery‐derived cerebral infarction .Methods :A total of 100 patients with large artery‐derived cerebral infarction treated in our hospital from Apr 2014 to Apr 2016 were selected .According to random number table ,patients were randomly and equally divided into atorvastatin group (received atorvastatin based on routine treatment ) and combined treatment group (received probucol based on atorv‐astatin group) ,both groups were treated for six months .Related indexes before and after treatment were compared between two groups .Results :Compared with atorvastatin group after treatment ,there were significant reductions in levels of TC ,TG and LDL‐C ,and significant rise in HDL‐C level (P<0.01 all);significant reductions in whole blood high shear viscosity [(6.23 ± 0.38) mPa/s vs .(4.20 ± 0.42) mPa/s] ,whole blood low shear viscosity [(21.17 ± 5.83) mPa/s vs .(18.10 ± 4.44) mPa/s] ,plasma viscosity [ (2.10 ± 0.45) mPa/s vs .(1.72 ± 0.34) mPa/s] and fibrinogen (Fg) level [(4.35 ± 1.36) g/L vs .(3.30 ± 1.38) g/L] ,P<0.01 all;significant rise in systolic blood flow velocity (Vs) [left :(87.43 ± 14.56) cm/s vs .(95.45 ± 18.37) cm/s]and mean blood flow velocity (Vm) [left :(60.89 ± 16.03) cm/s vs .(75.38 ± 19.36) cm/s]of left and right MCA ,significant reduction in pulsatility index(PI) [(0.85 ± 0.22) vs .(0.75 ± 0.12)] , P<0.05 or <0.01;significant reductions in unstable plaque score [(4.93 ± 0.40) scores vs .(4.12 ± 0.35) scores]and recurrence rate of cerebral infarction (16.00% vs .2.00% ) in combined treatment group ,respectiely P=0.001 ,0.014. Conclusion:Probucol combined atorvastatin can significantly reduce blood viscosity ,significantly improve hemodynamics in patients with large artery‐derived cerebral infarction .Its an‐ti‐atherosclerosis effect is obvious ,therefore it can be used to prevent or reduce recurrence of cerebral infarction .
