What is the difference between coronary heart disease and angina pectoris?

The difference between coronary heart disease and angina pectoris mainly lies in the degree of disease and symptoms. The degree of coronary heart disease is more serious and can lead to various complications. Angina pectoris is the early stage of coronary heart disease, mainly manifested as chest compression and other symptoms. The difference between coronary heart disease and angina pectoris mainly lies in the degree of disease and symptoms. Coronary heart disease is the abbreviation of coronary atherosclerotic heart disease, refers to coronary atherosclerosis caused by lumen stenosis or occlusion, resulting in myocardial ischemia, hypoxia or necrosis caused by heart disease. Angina pectoris is a type of coronary heart disease, is due to insufficient coronary blood supply, myocardial acute, temporary ischemia and hypoxia caused by clinical syndrome. Specifically, coronary heart disease is more serious than angina pectoris. In addition to angina pectoris, it may also lead to complications such as myocardial infarction, arrhythmia, heart failure, and even life-threatening. Angina pectoris is the early stage of coronary heart disease, usually due to physical activity, emotional excitement and other factors induced, manifested as chest pressure, pain, suffocation and other symptoms, rest or nitroglycerin can be relieved. In addition, the diagnosis of coronary heart disease needs to be confirmed by coronary angiography and other examination methods, while the diagnosis of angina pectoris is mainly based on symptoms and medical history. In terms of treatment, coronary heart disease requires comprehensive drug therapy, interventional therapy or surgical treatment, while angina pectoris mainly relieves symptoms by resting, adjusting lifestyle, taking nitrates and other methods. In short, although coronary heart disease and angina pectoris are cardiovascular diseases, the severity of lesions and symptoms are different, and the treatment methods are also different. If chest pain and other symptoms occur, seek medical attention in time, make a clear diagnosis, and take appropriate treatment measures. At the same time, for high-risk groups, such as hypertension, hyperlipidemia, diabetes patients, risk factors should be actively controlled to prevent the occurrence of coronary heart disease.
