Do shorter people have healthier hearts than taller people?

Does the actual length of how far a body has to pump blood and how much it has to work against gravity provide any positive health benefits?

Your question is more complicated than you probably realize. The short answer (pun intended) is that short people do have higher rates of cardiovascular problems, but not due to any difference in heart pumping strength due to gravity. Relatively recently a paper found that this is not due to the height of the individual, rather due to the genes that cause that individual to be tall. 

So it's not that being tall is good for your heart, it is that the genes that make you tall are good for your heart.
