Something I don't seem to have seen anywhere - not spelled out anyway - is how warfarin (in therapeutic range) affects one's risk of stroke. For example I'm 1 and 2 on those two CHAD scores (sorry, I can never remember the full acronyms) which scarily tells me I'm 9 times more likely to suffer a stroke than the average member of the population. A 2.2% annual risk.
So what does warfarin do to that risk? Anyone know? It must reduce it otherwise we wouldn't be taking it, but by how much? Obviously we are talking statistics so we can't expect any guarantees but it would be nice to think that while I'm returning an INR around 2.5, that 9x stat is substantially reduced.....?
