This paper reports the platelet aggregation and the level of plasma throm-boxane B2(TXB2) in patients with old myocardial infarction(OMI). The platelet aggregation was induced by adenosine diphosphate(1.25 μmol,2.5μmol) and adrenaline(1 μmol,2 μmol)and the platelet aggregation ratio in the first minute and the maximal platelet aggregation ratio were studied.The results showed that the platelet aggregation described above and the level of plasma TXB_2 in the 25 patients with OMI we treated were significantly higher than those in the control group(P<0.01),revealing a hypercoagulation state in patients with OMI.The technical factors which would affect the platelet aggregation were discussed as well.
