ACT is a none issue for me, i've been in range since my discharge over 18 months ago. By range i consider anything between 2 and 3.5, usually i hover on 2.7 but on the change of season i can have a couple of weeks when i adjust to the new temperatures outside and can jump/drop to the outer part of my range until i adjust.
Usually i'm on 5mg a day during summer but now its winter i'm on 5,5,5,4,5,5,5,4 repeating.
I still drink, probably a bottle of wine on a friday and a bottle on a saturday then a couple of glasses during the week on occasion (one last night). I have gone to the level of 1 bottle a night for 6 nights and not had an INR blip.
I've given up my motorbike and doing martial arts as the risk/benefit analysis wasn't good enough for me. Still active and lift weights, go to the gym, cycle, swim...its purely contact sports and potential hard impacts i avoid.
Other than that it's fine, no issues, nada.
I've cut myself and bled no more than normal, i've dropped stuff on my feet/legs/arms and not bruised at all never mind excessively.
I'd choose mechanical again, the surgery was ok so going tissue would not scare me re the surgery but the stress for the family etc was bad so choosing mechanical has the possiblility of not having them go through that stress again.
Would probably have gone on-x if it had a factory attached dacron graft but it didn't....this st-jude is a bit noisy but i'm used to it.
Good luck with your choice.
