Recovery time for open heart bypass surgery is usually 3 to 6 months due to the large incision, but it depends on the heart function and the severity of the disease. Recovery time is relatively long as the bypass surgery requires the chest to be opened in the center and the sternum to be sawn open. When the sternum is basically healed, the recovery time will be considered as basic, which usually takes about 3 months. If the heart function is poor, or the condition of the patient is not good, the recovery time will be longer, which is about 6 months. Before the sternum has not healed, the rehabilitation training should not be excessive, try to avoid chest expansion exercise, the upper limbs should not be lifting heavy activities, so as to avoid pulling the wound, which is not conducive to the recovery of the condition. After bypass surgery, we should pay attention to wound care, follow the doctor’s instructions for medication, and have regular checkups to prevent postoperative complications.
