Chest pain may be painless acute myocardial infarction. Or it may not be myocardial infarction, the specific situation needs to be combined with electrocardiogram, cardiac enzymes and other tests to clarify the diagnosis.
Acute myocardial infarction is not always characterized by chest pain. Painless acute myocardial infarction is not characterized by typical precordial pain and radiating pain at the onset.
Patients may present with symptoms of heart failure such as chest tightness, shortness of breath, and dyspnea. There may also be no symptoms at all, and the ECG may be characterized by ST-segment dynamic changes or Q waves, and marked increase in cardiac enzymes.
If there is no chest pain and the relevant auxiliary examinations, such as cardiac enzymes and electrocardiogram, do not have the characteristics of myocardial infarction, it is not considered to be an acute myocardial infarction attack.
If acute myocardial infarction is considered to be present, the patient should be seen immediately for further diagnosis and treatment under the guidance of a physician.
