Myocardial infarction is a serious disease that poses a severe threat to human life and health. The basis of its onset is myocardial ischemia, mainly due to coronary artery infarction. It generally manifests as severe pain in the precordial area, and some may experience gastrointestinal symptoms such as nausea and vomiting, eventually leading to overall weakness, fainting, and coma. Patients may exhibit symptoms of cerebral ischemia, such as dizziness, disturbed consciousness, and confusion. Some may experience diffuse cerebral ischemia. After a myocardial infarction occurs, it is crucial to provide immediate rescue to save the patient's life.
