Question 1: What does heart bypass mean? As the name implies, bypass surgery is to take the patient's own blood vessels (such as internal thoracic artery, great saphenous vein of lower limbs, etc.). ) or vascular substitutes connect the distal end of the narrow coronary artery with the aorta, so that the blood bypasses the narrow part and reaches the ischemic part, improving the blood supply to the myocardium, thereby achieving the purposes of relieving angina symptoms, improving cardiac function, improving the quality of life of patients and prolonging life. This operation is called coronary artery bypass grafting, which establishes a smooth path between the aortic root filled with arterial blood and ischemic myocardium. Therefore, some people call it "bridging" in their hearts, commonly known as "bridging".

Gu, an expert in cardiac surgery in anzhen hospital, said that when coronary heart disease is mild, only the feeling of tightness in the precordial area and paroxysmal pain in the left arm or upper abdomen after strenuous activity appear, that is, angina pectoris. In severe cases, even minor activities such as eating and dressing are restricted, and there will be myocardial infarction and sudden death. Generally speaking, when the degree of coronary artery stenosis is less than 50%, it has little effect on blood flow, and when the degree of coronary artery stenosis reaches 75%, it will obviously affect blood flow and produce angina pectoris. Therefore, when the stenosis degree of single coronary artery reaches 75% or the stenosis degree of more than two coronary arteries exceeds 50%, coronary artery bypass surgery is needed. Many patients who have received coronary angioplasty and installed stents (commonly known as PTCA) in the coronary artery need bypass surgery in time once angina pectoris recurs. This can not only eliminate angina pectoris,
