I am 67 and have CAD with two MI's and one stent. When I walk about a half a mile I am fine, but when I increase to one mile I get lightheaded. I don't have any other symptoms, no SOB or chest pain. I just wondered if others have similar symptoms.
Keep moving, it makes it harder for the undertaker to catch you. Don
Have you spoke to your dr about this. I'm curious to. I find that I cannot tolerate the heat anymore. But I noticed this when I started taking Plavix. And one of the side effects is tiredness. My dr said no, but I think he needs to do is homework. When its cool out I'm fine. Would love to know what your dr thinks it might be. Laray
