Objective To observe the clinical effect of Small-dose Rivaroxaban on the treatment of UA.Method To collect 165 cases of UA patients hospitalized at certain hospital in Fuxin

Liaoning

and divide them into the Observation Group and Comparison Group at random

containing 83 and 82patients respectively.Both groups received treatments from conventional dual anti-platelet aggregation

low molecular heparin calcium 5

7

dhypodermic injection of anticoagulants

βreceptor blocker to reduce the oxygen consumption of cardiac muscle

and the application of ACEI to control blood pressure

while the former was made to take Rivaroxaban at2.5mg a time and once a day after ceasing taking low molecular heparin calcium.After a session of eight weeks

the curing effect and side-effects of the two groups of patients were compared.Results The Observation Group had 66 cases of marked effect

12 cases of observable effect

and 5cases of non-effect

the same indexes for the Comparison Group were 58

9

and 15 respectively.The overall effectiveness of the former was 93.98%

and that of the latter was 81.71%.In comparison to the latter

the patients of the former saw marked improvements in aspects such as the average numbers of the outbreak of angina

the length of angina

and the ECG ST segment depression at angina after the treatment

and the differences of the two groups were statistically significant（P

<

0.05）.The bleeding complications of the former also had no significant increase compared with the latter.Conclusion Oral taking of small-dose Rivaroxaban has a marked curing effect on the treatment of UA.
