Objective To investigate the possible mechanisms of fasudil on acute myocardial infarction (AMI)by observing the changes of hemorheology and inflammatory factors.Methods 120 patients diagnosed AMI in our hospital were randomly divided into the two groups:60 cases in the control group were given the conventional treat-ment and the other 60 cases in the treatment group were added fasudil for 2 weeks based on that.Then we analyzed the changes of hemorheology and inflammatory factors.Results 2 weeks later,the whole blood restore viscosity,plasma viscosity,CRP,IL -1β,IL -6 and TNF -βin the two groups were all obviously decreased than those of before(P <0.05),while,packed cell volume in the treatment group was obviously decreased as well (P <0.05).Furthermore, the changes in the treatment group were more significant compared with the controlled group (P <0.05).Conclusion Fasudil intervention on AMI can improve the situation of hemorheology and relieve the inflammation more effectively than conventional treatment.
