The degree of platelet activation and damage in 15 cases with acute myocardial infarction (AMI) receiving thrombolytic therapy and 15 cases with AMI receiving anticoagulant therapy were studied in vivo and in vitro by using specific monoclonal antibodies (SZ-51 & S12) against alpha-granule membrane protein 140 (GMP-140). Clinical indexes and myocardial enzyme changes in the two groups of patients were also observed. The results showed that the number of GMP-140 molecules on platelet surface and the concentration of GMP-140 in plasma were increased before treatment. The number of GMP-140 molecules on platelet surface began to decrease on the 1st day and returned to baseline on the 7th day after treatment. The concentration of GMP-140 in plasma reached a peak on the 1st day, began to fall on the 2nd day and returned to baseline on the 3rd day after treatment. There were no significant differences in the dynamic changes of number of GMP-140 molecules on platelet surface and the concentration of GMP-140 in plasma between groups of thrombolytic therapy and anticoagulant therapy. In vitro experiment showed that the thrombolytic medicine urokinase neither activated platelets nor inhibited platelet activation induced by thrombin. Significantly greater reperfusion rate and earlier appearance of CK and CK-MB peaks were found in the thrombolytic than in the anticoagulant group. LVEF determined by echocardiography, rate of return of ST segments to baseline and alleviation rate of chest pain were significantly greater and complications of AMI (ventricular fibrillation, left ventricular failure and angina) were less in the group receiving thrombolytic therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

The molecular markers of platelet activation, coagulation and fibrinolysis were detected in 60 cases of coronary heart disease (CHD), including 15 cases of stable angina (SA), 21 cases of unstable angina (UA) and 24 cases of acute myocardial infarction (AMI). The results showed that the platelet granule membrane protein 140 (GMP-140) level increased obviously in CHD groups compared with normal control, suggesting that platelet activation existed in CHD. Prothrombin fragment F1 + 2 and fibrinopeptide A (FPA) were examined to observe the activation of coagulation. No difference was found between SA group and normal controls, while their levels in both UA group and AMI group were significantly higher than in normal control and SA group (both P < 0.05). D-D dimer and alpha 2-plasma inhibitor (alpha 2-PI) were detected to observe fibrinolytic state. The results showed that no difference existed between SA group and normal controls, while both D-D dimer and alpha 2-PI in UA group and AMI group were significantly elevated than those in SA group and normal controls (P < 0.05).
