Hypercoagulable states can be detected by measuring activation peptides, enzyme-inhibitor complexes, and fibrin/fibrinogen degradation products, which are markers of hemostatic activation. A series of these prethrombotic markers has been evaluated in the elderly, pregnancy, diabetes and acute myocardial infarction patients (n=30 in each group) as well as in hematologic malignancies (n=42). The parameters assayed were: prothrombin fragment 1+2 (F1+2), thrombin-antithrombin III complexes (TAT), fibrinopeptide A (FPA), plasmin-alpha2 antiplasmin complexes (PAP) and D-Dimer. Results were compared with those obtained in a group of 30 healthy subjects. We found a significant increase of F1+2, TAT and FPA in elderly (p<0.05), acute myocardial infarction (AMI) (p<0.01), hematologic malignancies (p<0.01), and pregnancy (p<0.0001), indicating a marked clotting activation. Diabetic patients under strict metabolic control only presented a moderate increase of TAT (p<0.05), suggesting a slight activation. We also observed a highly significant elevation of PAP and D-Dimer in elderly (p<0.001), AMI (p<0.0001), and malignancy (p<0.0001), indicating an activation of the fibrinolytic system. The combination of selected fibrinolytic and coagulation measurements is useful for the detection of a hypercoagulable state in conditions characterized by a risk of thrombosis.

D011237 Predictive Value of Tests In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
