Is coronary heart disease the same as angina pectoris?

Coronary heart disease and angina pectoris are not the same, coronary heart disease is the abbreviation of coronary atherosclerotic heart disease, is due to coronary atherosclerosis, caused by vascular lumen stenosis or obstruction, resulting in myocardial ischemia, hypoxia or necrosis caused by heart disease; angina pectoris is a type of coronary heart disease, is due to coronary artery blood supply deficiency, myocardial acute, temporary ischemia and hypoxia caused by clinical syndrome.

Coronary heart disease and angina pectoris are different.

Although coronary heart disease and angina pectoris belong to heart disease, but their pathological basis, clinical manifestations and treatment methods are different. Coronary heart disease is the abbreviation of coronary atherosclerotic heart disease, is due to coronary atherosclerosis, caused by vascular lumen stenosis or obstruction, resulting in myocardial ischemia, hypoxia or necrosis caused by heart disease. Angina pectoris is a type of coronary heart disease. It is a clinical syndrome caused by acute and temporary ischemia and hypoxia of myocardium due to insufficient blood supply of coronary artery.

The main clinical manifestation of angina pectoris is paroxysmal chest crushing pain, which may be accompanied by other symptoms. The pain is mainly located in the posterior part of sternum and may radiate to the precordial area and left upper limb. Labor or emotional agitation often occurs. Each attack lasts for several minutes and disappears after rest or nitrate preparation. In addition to angina pectoris, coronary heart disease also includes myocardial infarction, arrhythmia, heart failure, sudden death and other types, and its clinical manifestations are more complex.
