I had an Aortic heart valve replacement surgery in July 2018 and have been on Warfarin ever since. I have my INR regularly checked and it's normally within 2-3 which is my target range, apart from one episode where it shot up to 14!! After a week in hospital and having excess fluid drained from around my heart and reducing my LFT from nearly 1000, my INR has always been within range.
18 months after my surgery though I still haven't regained any fitness, before the op i regularly played football and went running etc, now I struggle to go up a flight of stairs without getting out of breathless and feeling dizzy. I have tried to resume my sporting activities and build up my fitness but I really struggle and was wondering if it was the warfarin or if anyone else has had this problem.
Thanks for any feedback.
