Acute myocardial infarction can save. Acute myocardial infarction is myocardial necrosis caused by acute and persistent ischemia and hypoxia of coronary arteries. Atherosclerotic unstable plaque rupture or erosion leads to acute thrombosis in coronary arteries as the basis of its pathology, so that the coronary artery lumen is suddenly blocked, and myocardial ischemic necrosis occurs. Clinical treatment of acute myocardial infarction is affected by many factors such as environmental characteristics, patient’s own condition, onset time, infarction area, etc. At present, there are mainly interventional therapy, thrombolytic therapy, antiplatelet therapy, coronary artery bypass grafting and other methods. 1. Interventional therapy: It is a commonly used procedure for acute myocardial infarction, which can restore myocardial perfusion in a short time, and has a remarkable effect in saving patients’ lives and improving prognosis. It can effectively improve oxidative stress, reverse left ventricular remodeling, and improve the prognosis of patients. 2. Thrombolytic therapy: When there is no emergency intervention and the initial balloon dilatation cannot be completed within 90 minutes, if there is no contraindication to thrombolytic therapy, thrombolytic therapy should be carried out within 12 hours to improve myocardial perfusion as early as possible and prevent myocardial persistent necrosis. 3. Antiplatelet therapy: antiplatelet is the basis of acute myocardial infarction treatment, in patients of any age with acute myocardial infarction, whether or not to receive interventional surgery, should be carried out aspirin and other antiplatelet therapy. 4. Coronary artery bypass grafting: replacing the blocked coronary artery by transplanting the patient’s own normal blood vessels, so that the blood flow to the distal end of the coronary artery stenosis or obstruction, reaching the ischemic myocardium and restoring myocardial perfusion. When acute myocardial infarction occurs, it is necessary to actively consult the doctor and follow the doctor’s instructions for reasonable treatment.
