Question: I am a 78 year old male, 5'7" with type 2 diabetes which I have had for about 20 years controlled with metformin otherwise reasonably good health. I have noticed short occasional bouts of shortness of breath for a few months now that has been getting worse after even mild exertion this last month or so. I am under extreme stress and depression since this last month my wife of 61 years has been hospitalized for chronic heart failure and after a series of tests was placed on dialysis with a 50/50 chance of permanent dialysis, this was caused by the contrast XXXXXXX used in the scans. this is where all my depression sleep problems and stress come from. I find now that even mild exertion leaves me breathless and weak and I must sit down for about 5-10 min till I can catch my breath and it passes. I assumed I had some heart blockage and decided to try a popular oral chelation product called angiopram to clear up any plaque build up that may be causing this problem since I need to be there for her. What is your opinion? Could all this be just stress related? Could this oral Chelation program be harmful?
