Clinically, there is no such thing as ten seconds of self-help at the onset of a heart attack, and when a heart attack occurs, you should actively seek medical attention for general treatment, drug therapy and reperfusion myocardial therapy. 1. General treatment: bed rest, cardiac electricity, blood pressure, blood oxygen monitoring, defibrillator standby, if necessary, detection of pulmonary capillary pressure and venous pressure, the establishment of venous access, dyspnea and low oxygen saturation to be oxygen. 2. Drug therapy: ① Relieve the pain of infarction with morphine, pethidine, isosorbide nitrate and so on. ② antiplatelet therapy commonly used aspirin, clopidogrel, tegretol and so on. ③Anti-coagulation therapy to prevent thrombosis, commonly used low molecular heparin, naltrexed heparin and so on. ④ Lipid regulation to stabilize plaque commonly used atorvastatin, resuvastatin, etc.. 3. Reperfusion myocardial treatment: ① stenting: found within 120 minutes of infarction with conditions of stenting is generally preferred stenting. ② Thrombolytic therapy: 120 minutes of unconditional stenting, no contraindications (such as active bleeding, etc.), thrombolytic therapy can be selected. Coronary artery bypass grafting: commonly known as “bypass grafting”, can be chosen if the above two methods are ineffective. When a heart attack occurs, you need to go to the hospital immediately and ask a professional doctor to save your life, and you should not do it by yourself.
