Myocardial necrosis is generally known as myocardial infarction, and the treatment for acute myocardial infarction is based on pharmacotherapy, with thrombolysis, intervention or surgical treatment selected according to the condition. 1.Pharmacological treatment In the acute phase of chest pain attack in patients with heart attack, antiplatelet drugs and anticoagulant drugs need to be used immediately, patients whose blood pressure is not low can immediately take sublingual nitroglycerin and use statin lipid-regulating drugs as early as possible; in addition, other drug treatments need to be carried out under the guidance of cardiovascular physicians according to blood pressure, heart rate and the presence of comorbidities. Thrombolysis Thrombolysis is a treatment method to dissolve the fresh thrombus in the infarct-related coronary artery through intravenous injection of thrombolytic drugs, so that the occluded artery can be reopened rapidly. Patients who have thrombolysis 1-2 hours after the onset of the disease benefit the most. Indications for thrombolysis: Thrombolysis is preferred within 3 hours of acute infarction onset and when there are no conditions for emergency percutaneous coronary intervention. Patients with infarction <12 hours of onset, age ≤75 years, and no contraindications to thrombolysis are considered for thrombolysis. Percutaneous coronary intervention Percutaneous coronary intervention (PCI) is a treatment method to treat acute heart attack by applying interventional techniques to mechanically open the infarct-related artery. Emergency PCI is currently the preferred and mainstream treatment method for acute heart attack. Interventional indications: Emergency PCI includes coronary balloon dilation and stent implantation, which can mechanically open the occluded coronary artery and immediately restore myocardial blood supply and reperfusion. However, this technique requires a medical center with an experienced medical team and appropriate equipment to perform it. Direct PCI is almost always considered for patients with heart attack, especially those with contraindications to thrombolysis or bleeding complications; remedial PCI should also be performed for those who are unsuccessfully recanalized by thrombolytic therapy. 4. Coronary artery bypass grafting For patients in whom intervention cannot resolve the infarct blood flow reconstruction. It is to establish a channel between the proximal and distal ends of coronary artery stenosis by using blood vessels from other parts. Although heart bypass surgery has certain risks, the use of coronary artery bypass surgery is still one of the most effective means of treating coronary artery stenosis and myocardial ischemia worldwide. Which treatment method is adopted for heart attack depends on the severity of the disease and the individual patient's condition.
