That makes intuitive sense, if blood is under higher pressure they're going to need to work harder to prevent you from losing too much blood I would imagine.
Basically, yeah, that’s one of the concerns. Drug dosages and other things are affected too, but the most simple concern is “if we accidentally hit something and you start bleeding, above a certain blood pressure it won’t stop.”
Edit: Well, it will stop bleeding… once you lose enough blood.
