Objective:To explore the pathologic mechanism of blood-stasis syndrome in cardiopathy(BSSC) and its different syndrome types from the activity of fi brinolytic system.Methods:72 cases with BSSC,20 cases with non-blood-stasis syndrome in cardiopathy(NBSSC) were observed at random,20 healthy cases as control.The levels of tissue-plasminogen activator(t-PA) and plasminogen activator inhibitor-1(PAI-1) in blood plasma were detected by ELISA.Results:①The level of t-PA in the group of BSSC was signifi cantly lower than that in the groups of healthy control and NBSSC(P
