Relationship between angina pectoris and coronary heart disease

Angina pectoris is a type of coronary heart disease characterized by chest pain associated with myocardial ischemia, often triggered by physical activity, emotional agitation, etc., and relieved by rest or sublingual nitroglycerin. Coronary heart disease is atherosclerotic heart disease, which can lead to a variety of serious complications associated with a variety of risk factors. Diagnosis depends on clinical manifestations, examinations, and treatment includes drugs, interventions, and surgery. Preventive measures include healthy lifestyles and regular physical examinations. Angina and coronary heart disease are closely related diseases, and understanding their relationship is crucial for prevention, diagnosis and treatment. Angina is a type of coronary heart disease, chest pain caused by myocardial ischemia and hypoxia due to coronary atherosclerosis. Coronary heart disease is a heart disease caused by coronary atherosclerosis, which causes stenosis or obstruction of blood vessels, resulting in myocardial ischemia, hypoxia or necrosis. In addition to angina pectoris, coronary heart disease may also lead to myocardial infarction, arrhythmia, heart failure and other serious complications. Angina attacks are usually related to physical activity, emotional excitement, satiety and other factors, rest or sublingual nitroglycerin symptoms can be relieved. The occurrence of coronary heart disease is related to a variety of risk factors, such as hypertension, hyperlipidemia, diabetes, smoking, obesity, family history, etc. Diagnosis of angina pectoris and coronary heart disease mainly depends on clinical manifestations, ECG, coronary angiography and other examination methods. Treatment methods include drug therapy, interventional therapy and surgical treatment, etc. The specific treatment plan should be considered comprehensively according to the severity of the patient's condition, complications and other factors. For people with high risk factors for coronary heart disease, such as middle-aged and elderly people, hypertension patients, diabetes patients, hyperlipidemia patients, smokers, etc., regular physical examination should be carried out, including ECG, blood lipid, blood sugar and other examinations, so as to detect early and treat early. At the same time, maintaining a healthy lifestyle, such as smoking cessation and alcohol restriction, reasonable diet, moderate exercise, weight control, etc., is also very important for preventing the occurrence and development of coronary heart disease. In short, angina pectoris is a common manifestation of coronary heart disease. Understanding the relationship between angina pectoris and coronary heart disease is of great significance for timely diagnosis and treatment of coronary heart disease. At the same time, effective preventive measures are also essential to reduce the incidence and mortality of coronary heart disease.
