Hi - I was put on Clopidogrel by the hospital following my first stroke in 2017. I had massive side effects which landed me in A & E quite a few times. After about 6 months, my Stroke Consultant agreed to try me on aspirin which suited me well until Oct last year when I had a second stroke - this time a TIA. I was immediately put back on Clopi and this time thankfully, I have been ok. The Stroke Consultant said the aspirin wasn't enough to protect me from another stroke and if I didn't take it, I would continue to have mini-strokes.
The consensus of opinion from medical people is that Clopi (and a couple of other specific blood thinners names of which escape me at the mo) is the best drug combined with BP and statin medication for stroke patients although nothing can guarantee being stroke free for the rest of your life. I agree you could have been unlucky. I think a lot of people who have strokes, very healthy, non-smoking, non-drinking people and young people etc are unlucky. As the stroke nurse told me on the night of my big stroke, even the fittest of atheletes can have strokes. It's just a blip in the brain that flicks a switch and that's it - you've had one.
I'd be really interested to hear if you do have the test - please do keep us posted.
