I am post opp from 2005 I weighed in at 30st prior to surgery.

Presently I am a few lb's over 16.

My Question is this, until recently I have been on warfarin but in the last few months it has become extremely difficult to control.

I recently had a heart ablation for atrial Fibrillation I a being very closely monitored Warfarin wise this is what has shown that its not being very effective it keeps dropping dramatically from 3.5 to 1.3 in.

The cardiologist has suggested one of the new anticoagulant (N.o.a.c.) like riveraxoban dagibatran etc.

The problem is the BPD DS and malabsorption, apparently they can not be very effective.

Does anyone here on the forum take one of these new types of medication and doors they actually work effectively/ how do they know that they do as there does not seem to be any tests to ensure that you receive therapeutic effects ie anti coagulation.

If again you do have testing to ensure everything is as it should be, what are the tests carried out thus enabling me to present a possible answer to my cardiologist.

Thanks
