Dr. Bruce, Thanks again for your help with my medical last year. I was going to email you, but thought I would ask the question here in case others wondered. I think in a response in another thread you mentioned an annual stress test. As a general rule for a healthy over 50 male, how often would you recommend a stress test? In my case I had a stress test one year ago that was negative and I went longer than anyone else my Cardiologist could remember (although that may not be saying that much since most of his patients are old and many have heart conditions) I had an ischemic stroke three years ago. I was thinking of repeating my stress test every two - three years. I highly respect your opinion and would like to know your thoughts on the matter. Thanks again for your help and all the advice you give.
