I have been told that the INR safe range is b/w 2-3 for patients on triple anti-thrombotic therapy of 75mg <span style = 'background-color: #dae8f4'>clopidogrel</span>
, 80mg asprin , and warfarin - 10 years after aortic valve replacement.
However, it has also been mentioned that an INR of 1.5 - 2 is also acceptable. Please verify and confirm.
Patient is 71y active , still working medical professional, with Hx of Htn and aortic valve replaced in 2000 to manage Aortic Insufficiency.
Your prompt response will be greatly appreciated.
