Abstract:ObjectiveTo investigate the clinical effect of Yindan Xinnaotong Soft Capsules in the treatment of lacunar infarction.Methods From March 3,2016 to March 4,2017,94 patients with lacunar infarction admitted into our hospital were selected as research objects and evenly divided into two groups,47cases in each group.In control group,routine therapy was used,while in observation group,on the basis of the control group,Yindan Xinnaotong Soft Capsules was added.The score of neurologic impairment,fibrinogen level,hemorheological index,and clinical effect in the two groups were compared.Results In the observation group,the score of neurological impairment and fibrinogen level were both lower compared with those in the control group after therapy(P<0.05).The hemorheological indexes including high shear viscosity,low shear viscosity,plasma viscosity,and hematocrit after treatment in the observation group were all superior to those in the control group(P<0.05).The total clinical effectiveness rate was 93.62%,much higher than that in the control group,the differences were statistically significant(P<0.05).Conclusion Yindan Xinnaotong Soft Capsules can obtain a definite effect on treating patients with lacunar infarction,which is beneficial to the recovery of neurological function,and improvement of fibrinogen level and hemorheological indexes.
