title: [Novel method for calculation of hemostatic potential and its clinical applications. 2].
abstract: A formula for calculating the hemostatic potential is proposed: HV = -{Ig[(APTT + PTTIS)/(WBCT.Hct)] + IgPF/PT}, where APTT is activated partial thromboplastin time, sec; PTT prothrombin time, sec; IS index of sensitivity of thromboplastin reagent used; WBCT whole blood clotting time after Lee-White, sec; Het hematocrit; PF probability of liquid blood preservation: and PT probability of thrombotic complications. The aim of the study was to evaluate the probability of practical use of the method and its practical potentialities. Statistical analysis (1014 specimens from 402 patients) confirmed the correctness (plausibility) of our concept and of the model of hemostatic potential. Despite the difficulties of calculation, the resultant hemostatic potential value represents the actual conditions of hemostasis in vivo. The physiological norm is represented as small-positive values of hemostatic potential, reflecting the constant "readiness" of blood to coagulation. Time course of hemostatic potential demonstrates the hemostasis status and its stability during various exposures. The homeostatic potential is a value highly sensitive to hemostatic status and outer exposures. Its changes can be used as a criterion of therapy efficacy.
