Objective: To study the influence of Shenmai injection for hemorheologyof patients with myocardial infarction. Method :Seventy-four patients with myocardial infarction in our hospital from June 2008 to December 2010 were selected as research object

and they were randomly divided into control group(routine treatment group)37 cases and observation group(Shenmai injection group)37 cases

then the total effective rate

incidence of adverse reactions and indexes of hemorheology of two groups were analyzed and compared. Result :The total effective rate of observation group was higher than that of control group

incidence of adverse reactions was lower than that of contro group

whole blood viscosity

whole blood reduced viscosity and plasma viscosity

hematocritwere all lower than those of control group

(P＜0.05 or P＜0.01). Conclusion :The influence of Shenmai injection for hemorheology of patients with myocardial infarction is better

and it is worthy of popularization and application.
