摘要
Hypercoagulation is not detected in clinical practice with routinely performed blood coagulation tests. More advanced laboratory analyses to detect or monitor hypercoagulation have not yet been introduced into routine clinical management. Thromboelastography assesses the influence of plasma factors and platelets during all phases of haemostasis, thus permits evaluation of hypo- and hyper- coagulation status. This prospective study included assessment of 35 patients with thrombotic complications （II-nd group）, compared with 34 healthy controls （I-st group）. Haemostasis was analyzed with routine clotting tests： protrombin time （PT）, activated partial thromboplastin time （APTT）, fibrinogen, platelets and rotation thromboelastography （ROTEM~） with measuring time to 20 min. All data are presented as mean and standard deviation （SD）. Statistical comparisons of samples were performed by student＇s t-test. The sensitivity, specificity, positive and negative predictive value of the parameters was calculated by using the receiver operator characteristic （ROC） curves for two groups. There was significant difference （P 〈 0.05） observed in the parameters of ROTEM： clot formation time （CFT）, a-angle, maximum clot firmness （MCF） and thrombodynamic potential index （TPI） in the patient＇s population compared to the healthy controls. No significant difference was observed in CT （ROTEM） and routine coagulation tests when the two groups were compared. Rotation thromboelastography analysis demonstrated to be a reliable method for diagnosis of hypercoagulable state.
