Coronary heart disease and anemia are not the same type of diseases; they differ in mechanisms of onset, clinical symptoms, and treatment methods. Coronary heart disease is caused by long-term arteriosclerosis, leading to narrowing of the coronary arteries, which causes ischemia and damage to the myocardium, hence it is called coronary heart disease. The treatment for coronary heart disease involves the use of medications to improve blood supply by dilating the coronary arteries, as well as medications to promote blood circulation and remove blood stasis. Anemia is due to a reduction in blood cells, causing ischemia in peripheral tissues and organs, leading to a series of clinical manifestations. Treatment involves supplementing blood or providing hematopoietic elements, depending on the cause of the anemia.
