I had one done last year but it was because I was having some vague chest pains and wanted to make sure all was well. They did a stress/echo and everything came back clear. These tests may miss problems since they really only show cardiac electrical function and the echo gives you some idea of muscle movement. You would really need an angiogram or CAT scan if you wanted to 100% sure your arteries are clear. Both are costly procedures and angiograms do have some risk involved so unless you have a lot of family history and the cardiologist requires it I would not ask for it.
