Coronary heart disease is caused by pain.

Coronary heart disease pain is mainly caused by coronary atherosclerosis leading to myocardial insufficiency, causing myocardial hypoxia and metabolite accumulation, stimulating the heart autonomic nerve afferent fiber endings. Specifically, the blood supply to the heart muscle is affected when atherosclerotic plaques form and the lumen narrows or blocks. Transient hypoxia and acidosis may occur in the heart muscle during physical activity, emotional agitation, or other conditions that increase oxygen consumption by the heart muscle. These changes stimulate sensory nerve endings in the heart muscle, producing pain signals that are transmitted to the central nervous system through nerve conduction pathways, causing chest pain or discomfort. In addition, coronary heart disease pain may also be associated with complications such as myocardial infarction and arrhythmia. Myocardial infarction is caused by complete blockage of coronary arteries, which can cause severe chest pain. Arrhythmia may also cause myocardial ischemia and pain. In addition to coronary atherosclerosis, other factors such as aortic stenosis, hypertrophic cardiomyopathy, and myocardial bridge may also cause coronary heart disease-like pain. For patients with coronary heart disease, chest pain or discomfort should be seen immediately for detailed examination and evaluation to determine the cause of pain and appropriate treatment. Treatment includes medication, intervention or surgery, depending on the severity of the disease and the individual circumstances of the patient. At the same time, patients with coronary heart disease should adopt a healthy lifestyle, such as smoking cessation, weight control, moderate exercise, healthy diet, etc., to prevent the occurrence and development of coronary heart disease. Regular physical examination and screening for cardiovascular diseases are also important measures for early detection and treatment of coronary heart disease. In short, coronary heart disease pain is a serious symptom that needs attention. Timely medical treatment, clear diagnosis and appropriate treatment measures are essential to protect heart function and improve quality of life.
