Is angina a disease?

Angina pectoris is acute myocardial ischemia and hypoxia syndrome caused by coronary artery insufficiency. Typical symptoms are chest compression, mainly related to coronary atherosclerosis. Treatment methods include drugs, intervention and surgery. Prevention requires control of risk factors and improvement of lifestyle. Angina pectoris is a serious disease that needs to be paid enough attention to. Here are some important information about angina pectoris: 1. Definition: Angina pectoris is a clinical syndrome characterized by episodic chest pain or chest discomfort caused by acute myocardial ischemia and hypoxia due to insufficient coronary artery blood supply. 2. Symptoms: Typical symptoms of angina pectoris are chest pressure, pain or discomfort, usually located behind the sternum or in the precordial area, which can radiate to the left shoulder, left arm, neck or jaw. Pain can be dull, crushing pain or tightness, often accompanied by breathing difficulties, sweating, nausea, vomiting and other symptoms. The main cause of angina pectoris is coronary atherosclerosis, which leads to stenosis or obstruction of blood vessels and affects myocardial blood supply. Other factors such as coronary artery spasm, myocardial hypertrophy, arrhythmia, etc. may also lead to angina pectoris. 4. Risk factors: Angina is associated with a variety of risk factors, including hypertension, hyperlipidemia, diabetes, smoking, obesity, lack of exercise, family history, etc. Diagnosis: Angina is diagnosed mainly by symptoms, ECG, heart ultrasound, etc. The doctor may ask about the history, perform a physical examination, and determine whether angina is present based on the results of the examination. Treatment of angina pectoris includes drug therapy, interventional therapy and surgical treatment. Drug therapy mainly includes antiplatelet drugs, nitrates, beta blockers, calcium channel blockers, etc. to relieve symptoms and improve myocardial blood supply. Interventional therapy and surgical treatment are suitable for more severe patients. 7. Prevention: Angina prevention mainly includes controlling risk factors, improving lifestyle, regular physical examination, etc. Patients should quit smoking and alcohol, control weight, moderate exercise, low-salt and low-fat diet, active treatment of hypertension, diabetes and other diseases. In short, angina pectoris is a serious disease, if not treated in time, may lead to myocardial infarction, heart failure and other serious consequences. Patients should seek medical treatment early and receive standardized treatment and management to improve their quality of life and prevent adverse events.
