How long it takes to recover from bypass surgery depends on the patient’s specific condition and how the procedure was performed. Coronary artery bypass surgery is required for severe stenosis in multiple branches of the coronary arteries. Coronary artery bypass surgery is performed under general anesthesia with an open chest and can be performed either without cardiac arrest or under cardiac arrest with extracorporeal circulation. Surgery under cardiac arrest is relatively long, with more post-operative complications and slower recovery, and patients are usually discharged from the hospital about two weeks after surgery. Usually patients can basically carry out normal life and activities about three months after surgery, and can return to society and carry out normal work and exercise about six months after surgery. If the patient is older and has other underlying diseases, the recovery time will be relatively longer. Patients need to pay attention to rest after surgery, avoid strenuous exercise, pay attention to the combination of nutrition in diet, and review regularly.
