The coronary arteries are the blood vessels that surround the heart and are responsible for supplying blood to the heart muscles so that the heart receives the oxygen and nutrients it needs. If the coronary arteries become hardened, narrowed, or even blocked, coronary heart disease, or CHD, is formed. Treatment options include medication, coronary artery dilation, and coronary artery bypass surgery. Coronary artery bypass surgery is a procedure in which a piece of venous or arterial blood tubing (usually taken from the patient’s hand or leg, without affecting the patient’s circulation) is connected to the upper or lower end of an occluded coronary artery by means of a bypass, creating a shunt. This restores patency to the vessel. The bridged vessel may be blocked again, so please pay attention to the following items: 1, the diet should be light, low-fat, low cholesterol, low salt, high vitamin, high fiber, high protein.
