I am a 48 old male with recurrent Restenosis, don't smoke and I'm not diabetic. Already have 2 layers of stent in multiple places and had triple bypass all within 5 years time. My most recent angioplasty was this week, for which I had to go back 4 day later with symptoms. It looks like an older stented area has been closing rapidly and is questionable if its narrowed by more than 60%,.We are running out of option, and thinking of trying brachytherapy but I am concerned about side effects, please guide me I'm loosing hope.
