This is what I believe to be the case in these matters.
1. Ischaemic stroke and TIAs are strongly associated with both AF and CAS
2. AC reduce TIAs and stroke in AF. Aspirin not so helpful,
3. Aspirin recommended for TIAs due to CAS.
I'm just guessing now but I suppose some people have both AF and CAS. I see the logic of taking both an AC and Aspirin together. My excellent EP recommended I continue Warfarin combined with Aspirin, the latter being better for primary prevention of generalised atherosclerosis. I had taken this combination for 6 years without a problem but my new GP ruled against the Aspirin, because of the risk of causing a GI tract bleed.
Yes, Yes but what is your question Badger, said Toad.
Well Toad, my question is this
1. Perhaps we should not assume that Aspirin has no role in AF with TIAs
2. Perhaps my EP was right to recommend AC plus Aspirin (perhaps enteric coated) in some older AFers who are more likely to have atherosclerosis
Those are not questions Badger and even if they were you only get to ask one question, said Toad.
Shut up Toad, said Badger.
