ABSTRACT
Objective To investigate the effect of intermittent use of low molecular heparin (LMWH) on microembofic signal (MES) in patients with ischemic stroke on the basis of anti-platelet aggregation and statin therapy.Methods Ninety MES-positive patients with acute ischemic stroke detected by transcranial Doppler were randomly divided into a non-LMWH group (n =44) and a LMWH group (n =46).The non-LMWH group was treated conventionally with enteric-coated aspirin and atorvastatin.On the basis of conventional therapy,the LMWH group was treated with LMWH,subcutaneous injection of LMWH calcium 4 100 AXaIU every 3 months,twice a day,and one week as a course of treatment (a total of 3 courses).The number of MES,MES-positive rate and incidence of ischemic cerebrovascular events at 3 and 6 month were compared in both groups.Results There was no significant difference in the MES-positive rates at 3 month after treatment between the non-LMWH group and the LMWH group (70.45% vs.61.36% ;x2 =1.357,P =0.244),but the number of MES in the non-LMWH group was higher than that in the LMWH group (12.07 ± 10.16 vs.8.09± 8.13; t =1.470,P =0.043); the MES-positive rate at 6 month after treatment in the non-LMWH group was significantly higher than that in the LMWH group (36.96% vs.19.57%;x2=3.982,P=0.046),and the number of MES in the non-LMWH group was also significantly higher than that in the LMWH group (10.32 ±9.93 vs. 1.46 ± 3.27; t =5.450,P =0.000).There was no significant difference in incidence of ischemic cerebrovascular events at 3 month (2.17%vs. 9.09%,P =0.198 ),but the incidence of ischemic cerebrovascular events at 6 month in the LMWH group was significantly lower than that in the non-LMWH group (4.35% vs.20.45%,P =0.025).Conclusions On the basis of anti-platelet aggregation and statin therapy,the intermittent use of LMWH may decrease the MES-positive rate and the incidence of ischemic cerebrovascular events in the MES-positive patients with ischemic stroke at 6 month.
