Angina pectoris and myocardial ischemia are a disease?

Angina and myocardial ischemia are not the same disease.

Angina is a heart disease characterized by chest pain or discomfort, mostly caused by insufficient coronary blood supply. Angina patients may experience myocardial ischemia, but in addition, myocardial ischemia may also be associated with myocarditis, acute myocardial infarction, etc. The two are not exactly the same.

Emotional stress and stress may trigger angina attacks, so it is important to learn to manage emotions and cope with stress. Try relaxation techniques such as deep breathing, meditation, yoga, etc.
