The main treatments for the occurrence of myocardial infarction are as follows: 1. Absolute bed rest and reduced activity to avoid increasing the cardiac load; 2. Anti-platelet drugs, such as aspirin, clopidogrel, tegretol. Plaque stabilizing drugs, atorvastatin, resulvastatin, etc.; nitrate coronary dilation drugs, isosorbide mononitrate, nitroglycerin, etc.; 3. Time window, usually within 12 hours of disease onset, advocates timely opening of the patient’s coronary arteries. If it is a patient with multiple stenosis, bypass surgery should be performed for patients with coronary artery disease.4. Keep an eye on the patient’s heartbeat and respiration. If the pulsation of the carotid artery cannot be palpated, it means that the patient’s heart has stopped. At this time, chest compressions should be performed immediately, with a frequency of 100-120 times/min and a compression amplitude of 5-6 cm. Resuscitation should be insisted and not given up until the arrival of the ambulance personnel; 5. If there are enough personnel, arrange for personnel to meet the ambulance at the designated place so as not to delay the time of resuscitation.
