Study on the intensive lipid-lowering therapy in improving the prognosis of stroke and reducing relapse rate

Objective To observe cerebral apoplexy patients complicated with carotid atherosclerosis plaque given aggressive lipid lowering treatment on the prognosis of stroke and reduce the recurrence rate through the large sample study on neurological department of internal medicine.Methods 300 cases of cerebral infarction complicated with different degree of neck lesions were selected and randomly divided into 3 groups,each group had 100 cases.Intensive lipid-lowering group received fluvastatin,80mg/d + 100mg aspirin,conventional dose group received fluvastatin,40mg/d + 100mg aspirin,aspirin group was given aspirin 100mg.After 4 weeks,8 weeks,12 weeks,16 weeks,20 weeks,24 weeks,blood lipid level,changes in internal carotid artery plaque (CIMT),plaque area,and the incidence rate of cerebral vascular events after 24 weeks were observed.Results The results of intensive lipid-lowering treatment group IMT (1.06 ± 0.36) mm,plaque area (8.09 ± 0.47) mm3,the incidence rate of cerebral vascular events after 24 weeks (12％),serum lipid levels and regular dose group after treatment with IMT (1.19 ±0.39) mm,plaque area (9.91 ± 0.78) mm3,the incidence rate of cerebral vascular events after 24 weeks (18 ％),serum lipid levels after aspirin group were significantly reduced(P ＜ 0.05).Aspirin group before and after treatment,IMF,plaque area and lipid levels had no significant differences(P ＞ 0.05).Intensive lipid-lowering treatment group compared with the conventional dose group,IMT,plaque area and lipid levels improved obviously(P ＜ 0.05),the recurrence rate of ischemic cerebral vascular disease had significant difference compared with the other two groups (P ＜ 0.05).Conclusion Intensive lipid-lowering treatment on blood lipid levels,delay and reverse the carotid atherosclerosis is superior to conventional dose using fluvastatin group and simply antiplatelet group,and can prevent the recurrence of ischemic cerebrovascular disease.
