I got a pet scan done for prorate cancer concerns of metastatic spread. It showed as one of the findings that I had severe atherosclerosis involving coronary arteries. No one mentioned this and I just saw it when I reviewed the test results some six months later. Is this some thing that should be addressed immediately or can I wait until my next scheduled appointment with my cardiac Dr. He has never mentioned it be fore and is only treating me for a leaking aortic valve an high blood presure.
