I had an Mitral heart valve replacement thirty years ago and have always been on warfarin. I Monitor my blood monthly.
In 2006 I had a stent in the heart and now take even more warfarin, also monitoring it very closely.
If I don’t take enough warfarin I start having “mini-strokes”.
Only time I add extra Vitamin K or greens is if I have too thin blood, INR 5 or above. They want me between 3-4 INR.
Not long ago one of the doctors recommended Eliquis instead of warfarin. On the package of Eliquis it stated “Not for people with artificial heart valves.” So it was back to warfarin.
A woman I worked with had the same valve replaced in her heart. On Warfarin, someone told her she could just use aspirin so she did. Dead a few months later of a blood clot.
Anyone with an artificial heart valve needs warfarin period. When taking warfarin vitamin K consumption need to remain steady. DO NOT change your vitamin IK consumption without alerting your provider
