Coronary heart disease is fully known as coronary atherosclerotic heart disease. From its name, we can see that the basis of its onset is due to the formation of plaques and narrowing of the lumen in the coronary arteries that supply blood to the heart, leading to insufficient blood supply to the myocardium and a series of symptoms. So what are these symptoms? The common manifestations include chest tightness and chest pain in the precordial area after physical activity, emotional excitement, or even after a full meal. Some patients may also experience radiating pain in other areas, such as the back, shoulders, abdomen, and even the throat. Additionally, some patients may experience atypical symptoms such as palpitations and abdominal pain.
