OBJECTIVETo study the correlation between thrombolysis in myocardial infarction (TIMI) risk stratification and blood stasis syndrome (BSS) score in patients with unstable angina pectoris (UAP), and to analyze the relation of BBS degree and UAP clinical outcomes.

METHODSCollected were general data, demographic data, risk factors, Chinese medical symptoms and syndromes, coronary artery angiography results, relevant physical and chemical examinations from 114 UAP inpatients. Gensini score, TIMI risk score, and BSS score of these patients were calculated.

RESULTSThe BBS score and Gensini score were significantly positively correlated (r = 0.78, P < 0.01). The BBS score was significantly higher in those with lesion in three branches than those with lesion in one branch or in two branches (P < 0.05). The BBS score was significantly higher in the high risk group than in the lower risk group and the medium risk group (P < 0.01). The TIMI risk score was obviously higher in the severe blood stasis group than in the moderate blood stasis group and the mild blood stasis group (P < 0. 05, P < 0.01). The BBS score and TIMI risk score was positively correlated (r = 0.23, P < 0.05).

CONCLUSIONThe BBS score was positively correlated with more coronary arteries involved. The more severe BBS degree, the TIMI risk score more higher, and the BBS degree more syndrome.
