Hi all. My mum got diagnosed with AF yesterday and told me and my brother. She is 60 this year and has always had high blood pressure. They are going to put her on warfrin (i think thats how you spell it). I have tried to read online about it but it doesnt really explain the risks. Is this a serious condition, should we be worried? I lost my dad when i was 15 and the thought of anything happening to my mum is unthinkable.
