Following my second catheter ablation last year, I am now out of AF, and was taken off warfarin about 6 months ago. However, three weeks ago, I had a couple of symptoms which are indicative of a stroke, and was taken by ambulance to A&E after my husband dialled 999. I had a head CT, which showed no evidence of a bleed in the brain (apparently it was too early to tell whether there was a clot), so I was put on Clopidogrel. I have also had an ECG and Echocardiograph, which were both "normal". I have been reading some earlier posts on this site, where it was said that drugs such as Clopidogrel were not as good as warfarin at preventing strokes, so I'm somewhat concerned for my future health. Has anyone else had a similar experience, or got any advice for me?
