Study on the hypercoagulable state in patients with angina and myocardial infarction

Abstract

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 (bothP<0. 05). D-D dimer and α₂-plasma inhibitor (α₂-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 α₂-PI in UA group and AMI group were significantly elevated than those in SA group and normal controlsP<0. 05).
