ELI5: What changes (if any) occur to the circulatory system when someone becomes an amputee?

Are there pros, cons, or does the heart just know to account for the lost limbs?

At first, your blood pressure would increase, as the heart is working just was hard to push less blood a shorter distance.

But your circulatory system has a feedback system that monitors both how much blood is needed, and what pressure it is at.  It would eventually recognize the you were getting plenty of blood, and could lower the blood pressure by dilating arteries.
