What are the characteristics of cardiovascular blockage in the elderly?

Some elderly people experience myocardial infarction with atypical chest pain symptoms, which often leads to misdiagnosis and missed diagnosis.
Therefore, in elderly patients, sudden onset of severe arrhythmia, shock, heart failure with no known cause, or sudden onset of more severe and persistent chest tightness or chest pain should be considered as a possibility of having this disease, and dynamic observation of ECG and serum myocardial necrosis marker measurement should be performed for a short period of time to determine the diagnosis.
