Your bud might - if he hasn't already - want to get an ecg cardiogram thing on a treadmill, that will give an indication of any irregularity. If there is then he might get an angiogram from a cardiologist and that will give a better reading. Further on from that there's a test you get where they put you on the treadmill and then pump radioactive dye into you and then throw you in some sort of machine like a cat scan thing (but I don't know if it is) and they get a really good nuclear medicine look at what's going on.
