Angina is beating pain?

Angina is usually not a throbbing pain, but a dull, pressing, or constricting sensation that may radiate to the left upper limb, left shoulder, neck, back, or jaw. Angina pectoris is a disease caused by myocardial ischemia and hypoxia caused by coronary atherosclerosis. Its main cause is coronary artery stenosis or obstruction, resulting in insufficient blood supply to the myocardium. When the myocardium is hypoxic, it will produce pain. The pain characteristics of angina pectoris mainly include the following aspects: 1. Pain site: Angina pain is usually located behind the sternum or in the precordial area, but may also appear in the left upper limb, left shoulder, neck, back or mandible.2. Nature of pain: The nature of pain is dull pain, crushing feeling or tightening feeling, which may be accompanied by pressure, choking feeling or dying feeling.3. Duration of pain: Angina pain usually lasts for a few minutes to ten minutes, generally not more than 30 minutes. 4. Predisposing factors: Angina attacks are usually related to physical activity, emotional excitement, satiety, cold and other factors. It should be noted that the pain characteristics of angina pectoris may vary from individual to individual. In some cases, angina pectoris may be manifested as toothache, stomachache and other atypical symptoms, which are easily misdiagnosed. Therefore, if symptoms of suspected angina pectoris occur, you should seek medical attention in time and perform relevant examinations, such as ECG, coronary angiography, etc., to confirm diagnosis and take corresponding treatment measures. In addition, for high-risk groups, such as those with hypertension, diabetes, hyperlipidemia, smoking and other cardiovascular disease risk factors, regular physical examination should be carried out in order to detect and treat cardiovascular disease early and prevent angina pectoris. At the same time, maintaining a healthy lifestyle, such as smoking cessation, weight control, moderate exercise, low-salt and low-fat diet, can also help prevent the occurrence and development of cardiovascular disease.
