The study was a prospective, randomized, non-blinded trial for which the patients were randomized into two groups, (i) weekly INR self-testing and (ii) monthly INR clinic-testing, using a stratified method of adaptive-allocation that was determined according to the duration of anti-coagulation and the indication for Warfarin. Although the study ...
The normal range for a healthy person not using warfarin is 0.8–1.2, and for people on warfarin therapy an INR of 2.0–3.0 is usually targeted, although the target INR may be higher in particular situations, such as for those with a mechanical heart valve. If the INR is outside the target range, a high INR indicates a higher risk of bleeding ...
Warfarin is indicated for the prophylaxis and treatment of venous thrombosis and its extension, pulmonary embolism; [9] prophylaxis and treatment of thromboembolic complications associated with atrial fibrillation and/or cardiac valve replacement; [9] and reduction in the risk of death, recurrent myocardial infarction, and thromboembolic events such as stroke or systemic embolization after ...
The monitoring of warfarin and keeping the international normalized ratio (INR) between 2.0 and 3.0, along with avoiding over and under treatment, has driven a search for an alternative. [3] [14] A naturally occurring inhibitor of factor Xa was reported in 1971 by Spellman et al. from the dog hookworm. [15]
The INR test measures the time it takes for a clot to form in a blood sample relative to a standard. An INR value of 1 indicates a level of coagulation equivalent to that of an average patient not taking warfarin, and values greater than 1 indicate a longer clotting time and, thus, a longer bleeding time. Assessing bleeding risk
