What should INR be for a mitral valve replacement?
What should INR be for a mitral valve replacement?
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 INR goal for aortic valve replacement?
| Valve position | Valve type | INR target in patients WITHOUT additional risk factors |
|---|---|---|
| Aortic or pulmonic | On-X valve | 2.5 for first 3 months; thereafter 1.5 to 2.0 |
| Low-risk valves | 2.5 | |
| High-risk valves | 3.0 | |
| Mitral or tricuspid | Low-risk valves | 3.0 |
What is the recommended INR for mechanical aortic valve?
The INR target recommended in evidence-based guidelines for most warfarin indications is currently 2.5, with a range of 2.0 to 3.0. For patients with mechanical mitral valve replacements, a slightly higher target of 3.0, with a range of 2.5 to 3.5, is recommended.
Do bioprosthetic valves require warfarin?
All patients with mechanical prosthetic valves require lifelong anticoagulation with a VKA (eg, warfarin). DOACs include the oral direct thrombin inhibitor dabigatran and the direct factor Xa inhibitors rivaroxaban, apixaban, and edoxaban.
What is the normal INR value?
In healthy people an INR of 1.1 or below is considered normal. An INR range of 2.0 to 3.0 is generally an effective therapeutic range for people taking warfarin for disorders such as atrial fibrillation or a blood clot in the leg or lung.
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 is the best INR level?
What is INR level?
Overview. You had a blood test to check how long it takes your blood to clot. This test is called a PT or prothrombin time test. The result of the test is called the INR level. A high INR level can happen when you take warfarin (Coumadin).
Why is warfarin used in a prosthetic valve?
Prosthetic valves require consideration for anticoagulation postoperatively to prevent thrombotic events. The traditional method of anticoagulation is warfarin which requires frequent blood test to check prothrombin (PT) time and International ratio (INR).
Why is warfarin prescribed after valve replacement?
Oral warfarin anticoagulation is a long-term treatment that is required after heart valve replacement. This treatment can prevent serious complications, such as embolism, thereby increasing patients’ postoperative survival rates and quality of life.
What is a critical INR level?
[8]For patients who are on anticoagulant therapy, the therapeutic INR ranges between 2.0 to 3.0. INR levels above 4.9 are considered critical values and increase the risk of bleeding.
