[Effects of guan-mai-shu on tissue-type plasminogen activator and plasminogen activator inhibitor in the plasma of patients with coronary heart disease].

Effects of Guan-Mai-Shu (GMS), a traditional Chinese medicine preparation, on tissue-type plasminogen activator (t-PA) and plasminogen activator inhibitor (PAI) in the plasma of patients with coronary heart disease were studied. It was found that those patients had a significant decrease in t-PA activity (P < 0.05) and a significant increase in PAI activity (P < 0.01) compared to healthy subjects. After treatment of GMS, t-PA activity significantly increased (P < 0.001), while PAI activity decreased (P < 0.001). These results indicated that GMS could raise t-PA activity and reduce PAI activity in the plasma of patients with coronary heart disease.
