Objective: To investigate the clinical efficacy of sodium tanshinone ⅡA combined low molecular weight heparin treatment for unstable angina patients. Method :A controlled study of patients after informed consent

random allocation method

cases were divided into treatment and control group of 60 cases each. The control group was treated by conventional methods

the treatment group on the basis of the control group

the low molecular weight heparin calcium+sodium tanshinone ⅡA was used. Two groups before and after treatment were observed

including ECG

bleeding time

coagulation time

prothrombin time

the efficacy was determined by analyzing and comparing various indicators. Result: ① The ECG comparison:the treatment group had higher efficiency and efficient

the difference was significant(P<0.05);② Clinical comparison of two groups: the effective rate of the treatment group was 88.33%

control group rate was 65.00%

higher efficacy showed in the treatment group

the difference was significant(P<0.05); ③ In the treatment group three indicators of coagulation(bleeding time

coagulation time

prothrombin time) showed no changes before and after treatment

significant changes in the control group

the difference was significant(P<0.05). Conclusion: The effect of conventional treatment plus low molecular weight heparin+sodium tanshinone ⅡA treatment for patients with unstable angina is safe. It is easy to use

and worth to be popularized.
