Since only one part of the body is being affected, it would make sense to only adjust that particular system. If you adjust the
heart, that affects the ENTIRE circulatory system which may be problematic.

Changing blood vessel diameter vs. HR is much safer and clinically relevant. It is much easier to manipulate BV diameter as HR such remain in an acceptable range
