What should your INR be with a mechanical valve?
A target INR range of 2.5–3.5 is the current recommendation in patients who have undergone mechanical mitral valve replacement [5–7].
What is the goal INR range for a patient with non valvular AFIB on warfarin therapy?
Atrial Fibrillation In patients with non-valvular AF, anticoagulate with warfarin to target INR of 2.5 (range, 2.0-3.0).
What is the INR valve for patient receiving warfarin?
In most situations the INR target is 2.5 (target range 2.0 – 3.0). This range is appropriate for the prophylaxis or treatment of venous thromboembolism and reduction of the risk of systemic embolism for people with atrial fibrillation and valvular heart disease. In some situations higher ranges are more appropriate.
What does an INR of 2.5 mean?
In most situations, the target INR is between 2–3. For some people who have a high risk of a blood clot, the INR needs to be higher – about 2.5–3.5. If your INR is above the target range, this means that your blood is clotting too slowly and you are at risk of bleeding.
What INR level is Coumadin held?
The anticoagulant effect of warfarin should be kept at an international normalised ratio (INR) of about 2.5 (desirable range, 2.0-3.0), although a higher level may be better in a few clinical conditions. The risk of bleeding increases exponentially with INR and becomes clinically unacceptable once the INR exceeds 5.0.
What is therapeutic PT for Coumadin?
When therapy with coumadin is begun, the dose is guided by monitoring the prothrombin time. Therapeutic levels are generally between 1 1/2 and 2 times normal, depending on the patient’s need for anticoagulation. Expressed in terms of the INR, the range is between 2.0 and 3.0.
How do you adjust warfarin based on INR?
A nice “rule of thumb” for dose adjustments near the target range (generally works for INRs from the high 1s to low 4s): If you want to change the INR by 0.5-1 unit, increase or decrease the weekly dose by a daily dose. Example: Your patient has been taking warfarin 5mg daily for more than 2 weeks and INR is 1.8.
Do bioprosthetic valves need anticoagulation?
Long-term risk — With anticoagulation, the long-term risk of symptomatic systemic thromboembolic complications in patients with mechanical valves is similar to that with bioprosthetic valves, which generally do not require long-term anticoagulation [5-9].
