Hello, everyone. I joined this forum because my father, who is 64, just had 4 bypasses on December 23rd. He came home on the 3rd day after surgery because he was doing so well. He didn't have a heart attack, but he had 4 blockages. Anyway, since coming home he has had a dry cough. He doesnt nor has he ever smoked. When he is up doing his walking or sitting up, he doesn't have it, but when he lies down at night or if he starts talking for a long period of time he has a slight cough to having coughing fits. I called his cardiologist and they told me it was normal, and they knew it was painful, but it was normal. He went to see his primary care physician and she checked him over and said he was doing great. His cough has gotten better, but he is still worried about it, especially since everyone he knows who has had bypass surgery (they had theirs 8 to over 10 years ago) is telling him it isn't normal and he should be worried. I've rsearched on here and other medical sites as well as talking to the doctors myself, and everything I can find says that the coughing is part of it. He is not taking one of the ACE inhibitors that causes a cough, at least that I know of, but still everything I find dealing with recent bypass surgeries says the cough is normal. Can anyone here confirm that they have experienced this and at everything I'm saying is correct? Thanks so much!
