If your insurance will cover going to a cardiologist, that's what I did. I've been Type 1 for 25 years now and am 52. I have some family history with my grandparents of heart atacks and that's considered a secondary risk. I figured with the family history, diabetes for 25 years and my age, that it sure wouldn't hurt anything to get checked out.
I do an annual stress echo test and have done the ankle-brachial index test before. So far so good, but I figure that if I have problems later that having the baseline data from these tests will help them spot any problems.
