If the patient has pain in the heart after exertion, we should be highly alert to angina pectoris. Because the typical attack of angina pectoris is characterized by emotional excitement, physical activity, or cold weather stimulation caused by the upper and middle chest pain discomfort, usually lasts 3-5 minutes, containing drugs or rest after physical labor can be significantly relieved. Therefore, when the patient has a typical pain attack in the upper sternum, we should be highly alert to the possibility of angina pectoris acute coronary syndrome, and should carry out electrocardiography, coronary CT and other tests to clarify whether there is coronary heart disease for further standardized treatment. If the standardized treatment is not carried out, the patient may further develop into acute myocardial infarction, there is such a possibility.
