Nev,
Just to add a quick insight to the crossover between medical care and the medical industry....
A while back, I had an 'episode'. Possible stroke. The hospital admitted me and did a CAT scan and said "It doesn't look like a bleed, but we cannot be sure until we do a MRI. Come back in a couple of weeks for an MRI and meantime take a quad dose of clopidogrel and stay on it".
I went home. A month later an MRI confirmed residual clot signs from a bleed.
The neurologist assured me this was not technically a stroke because it was at the cerebral cortex, therefore not within the brain.
In spite of anticaogulants, the bleed fortunately stopped by itself. Of course the potential for anticoagulants worsening a bleed was brushed aside. In reality it had the potential to finish me off the next day.
But it goes to show that the experts are not always right. And sometimes the most important thing is to get the patient out of the hospital.
