Once a myocardial infarction occurs, it is important to get to the hospital quickly for treatment. The process of resuscitation: First, the patient is given continuous cardiac monitoring, from which the patient’s vital signs, such as blood pressure, heart rate, and oxygen saturation, can be understood. In addition, high-flow oxygen inhalation, artificial endotracheal intubation if necessary, assisted breathing, and coronary dilation and anticoagulation drugs should be given. If the patient has severe arrhythmias, such as ventricular fibrillation, extracorporeal electric defibrillation should be given to restore the sinus heart rate, such as isosorbide mononitrate, aspirin, and other anticoagulant and dilation drugs for oral administration. In addition, coronary angiography can be performed for emergency myocardial infarction. Through coronary angiography, luminal stenosis can be clearly observed, and coronary stent implantation or bypass surgery can be given.
