Pain is the earliest symptom of a myocardial infarction, and its location and nature are very similar to angina. However, it often occurs during quiet or sleep, and the pain is very severe and widespread, lasting for several hours.

If shoulder pain is frequent, accompanied by chest pain, an ECG should not hesitate to do an ECG to see if the heart is ischemic. If the blood supply to the heart muscle is insufficient, it is most likely to be a "myocardial infarction".

Acute chest pain is mostly retrosternal crushing pain, usually accompanied by sweating or changes in complexion, and chest pain is usually persistent. If symptoms appear, it is recommended to seek medical attention as soon as possible, because timely rescue of myocardial infarction, timely coronary artery reconstruction or revascularization can effectively alleviate symptoms and save lives.
