A high protein diet also affects it-

In particular whey based protein shakes.

A bit more info, http://www.bloodjournal.org/content/bloodjournal/109/6/2419.full.pdf?sso-checked=true .
I take a vitk1 supplement of 100mcg daily and 45mcg k2 so I have a consistant vitk intake, I have increased my dose by 0.5mcg daily but it makes my inr more stable, I have had at 39yrs old a mechanical aortic valve also, I self test with a coaguchek and have self managed my dosing since AVR . I hope your recovery is going ok , its not the most pleasant experience :-),
You will most likely find that after surgery for the next few months your dose will most likely need to be increased gradually as ur body heals, so dont be alarmed as its normal.
