My husband has COPD and went to the hospital in July for breathing problems. while he was there they discovered a problem with his heart through blood work. It was determined through a cath. that he had a blocked artery and put in a stent. Ever since that hospital stay his condition has gotten much worse. His breathing is terrible, his legs are weak and he can't hardly walk without a walker. He is now on oxygen 24/7. we have told all his doctors and they have checked his heart with sonograms and a stress test. He is dramatically worse and we think something happened during the stent placement but they say everything is alright.
