Coronary heart disease, or coronary atherosclerotic heart disease, is also known as ischemic cardiomyopathy. It refers to a heart disease characterized by myocardial ischemia caused by atherosclerosis or accompanying spasm of the coronary arteries. This disease is a heart disease that occurs mostly after the age of 40. It is often seen in our daily life. The clinical manifestations are sudden onset of painful suffocation in the anterior chest region, shortness of breath, profuse sweating, and pallor, forcing the patient to stop activities, or in mild cases, to relieve itself within a few minutes and gradually return to normal after rest. The human heart is the equivalent of a pump in the body, pumping blood out and delivering it to various parts of the body, circulating endlessly to maintain normal tissue and organ function activities. The work of the pump is driven by electrical energy, while the work of the heart is maintained by the nutrients and energy brought by the arterial blood pumped by itself. The coronary arteries are a system of blood vessels branching out from the vascular system to supply blood, nutrients and energy to the heart, and are distributed in a ring shape in the front, back, left and right parts of the outside of the heart, like a crown of hats. Coronary heart disease is due to the deposition of lipid substances in the blood on the walls of the blood vessels, as the scale in the sewer pipe. Long-term deposition is the formation of atheromatous material deposits, and adhesion with the vessel wall, protruding inward, blocking the lumen becomes increasingly narrow. With the increase of deposition, the effective blood circulation to the heart is less and less. When the narrowing of coronary arteries exceeds 50-70%, it becomes difficult to maintain the nutritional needs of heart muscle activities, and various clinical symptoms appear as a result of inadequate blood supply. Even due to excessive deposition, blood supply is severely deficient, and muscle necrosis occurs at the site of effective blood supply due to ischemia and hypoxia, which is clinically referred to as myocardial infarction. Since the deposition of atherosclerotic material is a slow and long-term process in clinical practice, once coronary heart disease occurs, it indicates that it has been deposited for many years. It must be treated immediately to prevent aggravation of the disease. Therefore, the prevention of coronary heart disease is also a both early and long-term behavioral process, so the concept of prevention first and perseverance should be firmly established.
