Coronary artery bypass grafting is the creation of a channel between the proximal and distal ends of a narrowed coronary artery, allowing blood to bypass the narrowed area and reach the distal end, just as a bridge allows a highway to pass unobstructed across a mountain gorge or river. However, the materials used are not steel and concrete, but the saphenous vein, internal mammary artery, right gastroretinal artery, radial artery, and inferior abdominal wall artery. “Heart bypass” is the ideal treatment for coronary heart disease, what should be noted in the rehabilitation of patients after heart bypass? 1, wound care diligently when discharged from the hospital, there is a slight redness, pain, swelling at the wound, sometimes even last for several months, this is a normal phenomenon.
