Coronary artery bypass surgery is usually discharged after about 7 days with no problems in the review results, but we do not advocate that foreign patients should start their journey home immediately after discharge, especially if the journey is long, it is generally recommended to stay near the hospital for a few days to adapt before leaving. Transportation can be by car or train. Depending on the patient’s condition, if the journey is long, it is recommended to choose a station wagon or train sleeper that can lie flat. There is no standard answer to the question of whether many patients are concerned about whether they can fly, and there is certainly no problem to fly after full recovery. However, for patients who have just been discharged from the hospital, whether or not it is appropriate to fly home immediately depends on the patient’s specific situation, and we recommend that you consult your supervising physician before discharge. Our advice to you is that if you had a strong reaction and discomfort during takeoff and landing as well as when the airplane encounters turbulence before the surgery, it is recommended that you do not choose to fly when you are just discharged from the hospital. The wires and temporary pacemaker leads in your body will not cause you any damage or trouble when going through security, so please do not worry. However, if you have a permanent pacemaker installed, you need to explain to the staff before going through the security check that you cannot go through the security gate and that you need a special security check method. In addition, according to our experience, some airports will ask you to produce a certificate from the hospital for patients who have just been discharged from the hospital after cardiac surgery to fly, so we recommend you to prepare it beforehand.
