Abstract:
Objective Influence of the function of coagulation and anticoagulation in the elderly patients with thrombotic diseases by activated protein C resistance(APCR) was studied. Methods Prothrombin fragments 1 and 2 (F1+2),fibrinopeptide A (FPA)，soluble fibrin monomer complex(SFMC) were examined by enzyme linked immunoassay(ELISA); fibrinogen(FIB),antithrombin III antigen(AT-Ⅲ:Ag) and its activity(AT-Ⅲ:A), protein C antigen(PC:Ag) and its activity(PC:A) and APCR were determined using CA 530 blood coagulation analyzer. Results Compared the elderly patient group with thrombotic diseases with the healthy elderly group, the parameters of coagulation system were obviously increased 〔F1+2(5.4±0.6)nmol/L vs (2.6±1.3)nmol/L,FPA (6.9±1.9)μg/L vs (4.8±2.3)μg/L,SFMC (72.4±8.7)g/L, vs (56.3±11.7)g/L,FIB (5.18±0.68)g/L vs (3.82±0.74)g/L〕 and that of the anticoagulation system was significantly decreased〔AT-Ⅲ:Ag (212±19)mg/L vs (255±26)mg/L，PC:Ag (63.5±9.2)mg/L vs (82.7±20.1)mg/L〕.The above parameters changed more obviously in the elderly patients with positive APCR than those elderly patients with normal APCR. Conclusions APCR accelerated the activation of coagulation system and led to the weakening of the anticoagulation system function in the elderly patients with thrombotic diseases. The positive APCR may be one of the risk factors in the elderly patients who suffered from thrombosis.
