The purpose of coronary heart disease treatment is to reduce or relieve symptoms, restore heart function, prolong patients’ lives and improve their quality of life, etc. There are four types of treatment for coronary heart disease: lifestyle modification, medication, interventional treatment and surgical treatment. Interventional treatment includes percutaneous transluminal coronary angioplasty (PTCA), coronary plaque spinning, coronary plaque grinding, coronary plaque excision and aspiration, percutaneous coronary laser angioplasty, intracoronary stenting and thrombolytic therapy. Among them, PTCA+coronary stenting is the most commonly used one. PTCA is performed by puncturing through the femoral artery or radial artery, applying a guiding catheter and guiding wire to place a catheter with a balloon into the vessel, delivering the balloon to the appropriate location of the stenotic lesion in the coronary artery, and then increasing the pressure inside the balloon to dilate and compress the atherosclerotic plaque in the arterial wall. After pre-dilatation by PTCA, a metal stent is delivered to the lesion, and after precise positioning, the stent is released with appropriate pressure so that the metal stent is supported in the narrowed lesion in the coronary artery, causing the narrowed or collapsed vessel to expand outward and achieving the purpose of revascularization. Coronary interventions require only local anesthesia at the puncture site during the procedure. Patients undergo the procedure awake without any painful sensations and can talk casually with the surgeon on the catheter bed. After the procedure, only the puncture site needs to be bandaged with pressure, and there is no restriction of movement for those with radial artery access. If the femoral artery is the access point, the patient needs to lie down for 24 hours and can get out of bed. If there are no complications, the patient can be discharged from the hospital 3 days after surgery. From the current clinical studies, although the one-time cost of interventional treatment for coronary artery disease is higher, the net benefit of successful interventional treatment may be greater than that of medical drug treatment alone because it significantly improves the quality of patient survival, reduces the risk of dangerous events of coronary artery disease, reduces the number of hospitalizations, and reduces some of the routine medications. Interventional treatment of coronary artery disease has been popularized in tertiary hospitals nationwide, and the success rate of treatment is comparable to that of foreign treatment. However, the number of patients receiving coronary interventions in China is still far smaller than that in developed countries such as the United States. Indications for coronary intervention (1) Angina pectoris has not stabilized after active drug treatment. (2) Although angina symptoms are mild, there is clear objective evidence of myocardial ischemia and significant stenotic lesions. (3) Angina pectoris after interventional therapy or cardiac bypass grafting, with restenosis of the coronary artery lumen. (4) Interventional treatment within 12 hours of the onset of acute myocardial infarction, or 1-2 weeks later if more than 12 hours. Coronary artery bypass grafting was started in 1964, and the method is to take own lower limb vein, internal mammary artery or radial artery as the material for bypass grafting. Mostly under extracorporeal circulation, a bridge vessel is applied to create a channel between the proximal and distal ends of the coronary artery stenosis, allowing blood to bypass the stenosis and reach the distal end, like a bridge making a highway across a mountain gorge or river, thus improving the symptoms of myocardial ischemia and hypoxia and achieving the purpose of myocardial blood flow reconstruction. Surgery is performed. Usually the long-term patency rate of arterial bridges is higher than that of venous bridges, but arterial bridges are subject to certain restrictions and are more traumatic to remove, and the surgeon will decide which material to use for the bypass according to the characteristics of the coronary artery lesion. Due to the different medical equipment and technical level of each hospital, the indications for coronary artery bypass surgery are different, and it is generally believed that coronary artery bypass surgery can be considered in the following cases: (1) partial left coronary artery trunk lesions, i.e., those with high risk of intervention; (2) three branches of coronary artery lesions, especially in combination with diabetes; (3) combined valve disease and valve replacement; (4) post-infarction complications of large ventricular wall aneurysms, which need to be surgically removed; (5) ventricular wall aneurysms (5) multiple lesions in multiple branches of the coronary arteries, requiring multiple stenting and costly treatment.
