My 71 year old brother had quadruple bypass surgery about three weeks ago and has his first visit to thecardiologist tomorrow.  My brother still has shortness of breath and is on oxygen, he is sleeping in a chair inthe rehab afraid to lie in bed because he cannot breathe when lying down.  What questions should he be readyto ask his cardiologist in his visit tomorrow.  Oh, he is also a diabetic.
Thanks for your question on Chat Doctor. I can understand your brothers situation and problem. Breathlessness on lying down is not a good sign after bypass surgery. This suggests heart failure due to poor pumping of heart. So he should ask for 2d echo to determine heart function. About treatment, diuretics and isotropic Chat Doctor.
