I don't want to scare anyone, but this is a true story.
I have an ex male work colleague who I'd worked and laughed alongside for years, our whole office was like a big family. About 4 years ago, aged 60 he was told by his GP that he had AF and put him on beta blockers and aspirin! I explained to him that he should be on an anticoagulant and that aspirin was not recommended for AF now. As he didn't have any symptoms of AF, he decided he'd go with what the doctor had told him and who could blame him as a doctor should know best. The beta blockers didn't bother him much, just made him a little more breathless when he did long hilly walks with his fellow cricket playing buddies (had been a very active, sport playing man all his life).
Around last November I was devastated to hear that he had had a blood clot in his brain, been operated on and in hospital for many months. He is now wheelchair bound with an extremely poor memory and needs 24hour care by his wife.
As I have said this is just a warning to make sure you are on anticoagulants and not relying on aspirin to prevent clots.
