Not really. My parents (both physicians, just like a sizable part of my extended family) do not believe in unnecessary medical procedures, much like almost every other doctor. You don't become a cardiac physician unless you actually care about the people and what you do, trust me. Cosmetic surgery pays much more, holds less risk, and is less demanding if you're just in it for the money. In addition, most cardiac tests don't award the physicians any monetary value aside from decreasing malpractice risk through negligence.
