Hello ,
I am Dr. Mody we'd I would be addressing your concern .
I went through your history in detail .
Now there is a high probability that the atrial
fibrillation you had was because of
hyperthyroidism. Now considering that is has been completely taken care of there is to a fair chance that the atrial fibrillation may never occur again .
Considering your age as 60 yeqrs at that point of time , there is a possibility that atrial fibrillation may be because of age related degeneration of the heart , whereby the atrial fibrillation may come again .
Warfarin , xarelto are medications to prevent formation of clot in the heart thereby preventing the risk of stroke . So taking either of them has been shown medically to be helpful without doubt .
So my recommendation would be .
1) if there is enough evidence on
echocardiography and holter that the chances of atrial fibrillation occurring in future is rare , you may consider stopping warfarin or xarelto.
2) considering your age an underlying blockages in heart arteries should be always kept in mind .
A treadmill
stress test would be good rest to rule out the same
3) neither warfarin after so long or xarelto can directly cause the
numbness you describe.
4) Yes it can be a mini stroke ( what we call transient is chemical attack ) of the Brian
5) or in high probability it due to some compression of nerves due to age related denervation of
cervical spine , a simple X ray will rule that out , or muscular sprain
Let me know if further clarification is needed .
