Yes. Blood clots in part due to a well-known “cascade” of chemicals reactions when the right factors are present. Chemical reactions occur faster at higher temperatures, although go too far from body temperature and this will serve to break down the proteins that the enzymes are made of.
And this is also why Emergency Rooms are warmer than typical room temperature: to aid in blood coagulation.
Sweat-prone surgeons can get mighty drippy in there, with the heat added on top of the job stress.
