Hi, in 2014 I had a mechanical aortic valve fitted along with an aortic route replacement. I now take warfarin with an INR target of 3.
I'm planning a mountain biking trip to the alps in 2019 (I am aware of the risks) but have been told I cant do altitude when on warfarin for my condition. The problem is no one can tell me at what height does altitude become a problem. From extensive geeking I've come up with a figure of 2400 metres but not sure if this is correct. Any thoughts?
