Treatment for patients with acute ST-segment elevation infarction: First, patients should be monitored for ECG, blood pressure, blood oxygen, respiration, in and out fluid volume; Second, if patients have obvious pain and irritability, patients can be given symptomatic treatment such as sedation and analgesia, for example, morphine, in addition, nitroglycerin can be pumped intravenously to combat ischemia; Third, aspirin + tigretol or clopidogrel loading dose should be given and taken orally immediately. Fourth, the patient needs emergency reperfusion therapy within 12 hours of onset, and interventional therapy is preferred; if the hospital where there is no interventional condition and the transfer to a hospital with conditions for interventional therapy takes longer, there is no obvious contraindication to thrombolysis, the patient should be given thrombolytic therapy. Fifth, there are also anticoagulation, lipid regulation, control of ventricular rate, improvement of ventricular remodeling and other treatments, and if there is cardiac insufficiency, malignant arrhythmia, etc., targeted treatment is also required.
