[|Human|] hi doctor, my father just undergo CABG bypass surgery. After stay in the hospital for 2 weeks(after surgery), he discharged from the hospital. A few days at home, i noticed both of my fathers leg are swollen and sometimes he complaining shortness of breath, but if he coughing he felt relief. Is this normal for after CABG? should i send back him to hospital? Please help me. Thank you.
[|AI|]  Hello, I have gone through your query. Thanks for using Chat Doctor. I presume that he had leg veins used to graft her heart arteries. In that case swollen legs are common and needs just elevation of limb while sitting and while sleeping. His shortness of breath improving after coughing suggests that he may have secretion collected in lungs and needs good chest physiotherapy, My best wishes Chat Doctor.
