Serious illness: More seen by NP or CNS?

I've thought about becoming an ACNP, because I like complex illness and the ICU atmosphere and don't really care for primary care and prevention.

However, I've heard from some ACNPs and it seems that they primarily deal with less serious illnesses at the clinic...ie giving a stress test to someone with angina...rather than more serious illnesses at the hospital...ie adjusting a vasoactive drip on someone with cardiogenic shock. At least that's the impression I got.

Which makes me wonder if maybe a CNS role with a critical care focus would be better, more likely to be hospital-focused and more likely to be hands-on with the sicker patients.
