Had 3 stents in february but havr never felt any better. Had heart attack year before and apart from the unstable angina, i felt better before the stents. I can walk 100 steps before i have to stop. Im breathless. Have angina every day from doing simple housrhold tasks. Im at my wit's end. Cant bear to live like this. Am on bisoprolol, ramipril, plavix and aspirin. Have stage 4 kidney failure from the iodine contrast dye of angioplasties. Any advice most welcome!!
