After coronary artery bypass surgery, the patency of the “bridge” needs to be monitored. Patients with coronary artery disease should go to the hospital regularly for follow-up examinations after surgery, such as electrocardiogram, isotope or even coronary angiography, in order to detect possible problems as early as possible. In short, the smoothness of the “bridge” is inseparable from the patient’s own care and attention and the doctor’s concern. For post-coronary artery bypass grafting exercise, patients with coronary artery disease can initially walk around the room and the house, holding on to something while walking.
