OBJECTIVETo observe the intervention effects of acupuncture combined with standardized treatment of western medicine on blood-stasis syndrome in unstable angina (UA) patients with different thrombolysis in myo-cardial infarction (TIMI) risk stratification.

METHODSAccording to TIMI risk score, a total of 72 UA patients were included, 24 cases in low-risk (0 to 2 points) group, 24 cases in moderate-risk (3 to 4 points) group and 24 cases in high-risk (5 to 7 points) group. Based on routine standardized treatment of western medicine, acupuncture was applied at Xinshu (BL 15), Xuehai (SP 10), Geshu (BL 17), Danzhong (CV 17), Jueyinshu (BL 14), Ximen (PC 4) and Neiguan (PC 6) in three groups. Acupuncture was given once a day, 14 days as a session. After one session, each symptom score and total score of blood stasis syndrome were observed.

RESULTSOne patient dropped out respectively, and 23 patients in each group were included in the analysis. After treatment, the score of angina symptom and total score of blood stasis syndrome were significantly improved in three groups (all<0.01). The improvements of each score and total score of blood stasis syndrome in the high-risk group were superior to those in the low-risk group and moderate-risk group (<0.05,<0.01).

CONCLUSIONSWith the higher TIMI scores, the blood stasis syndrome is aggravated accordingly. Acupuncture combined with standardized treatment of western medicine could effectively intervene blood stasis syndrome, especially for the score of blood stasis syndrome of patients in high-risk group.
