I know this question has been asked before, but how many are on the new drugs? I would love to know the outcome of these drugs as I want to come off warfarin as they cannot tell me conclusively if I have AF but have stuck me on warfarin anyway. I am fed up with the diet aspect and also the bloods taken every week as my INR is up and down like a yo yo. Can anyone tell me what these new drugs achieve versus warfarin? Do you have to be checked? Do they cause bleeding etc etc? I do not know what it feels like to go into AF as at 72 all i have ever had is a pulpation now again, but have had chest pains (which felt like indigestion) and rushed off to hospital, but nothing showed up after all the cardio tests an stress tests i have had done plus its not angina.
