The treatment of lower wall infarction of the heart mainly includes general treatment, pain relief, antiplatelet therapy, lipid regulation therapy, anticoagulation therapy and reperfusion myocardial therapy. 1. General treatment: patients need to rest fully and keep the environment quiet. Cardiac monitoring, blood pressure and respiratory monitoring should be carried out. At the same time, it is necessary to establish a venous channel to ensure that the route of drug administration is unobstructed. 2. Relieve pain: morphine, pethidine, metoprolol, etc. are commonly used. 3. Antiplatelet therapy: Aspirin combined with clopidogrel and other drugs are often used for antiplatelet therapy. 4. Lipid-regulating therapy: it should be applied as early as possible. Commonly used drugs are simvastatin, atorvastatin and other drugs. 5. Anticoagulation therapy: patients without active bleeding and other contraindications to anticoagulation need to use heparin, low molecular weight heparin, sulfadoxine sodium, warfarin and other drugs for anticoagulation therapy. 6. Reperfusion myocardial therapy: including percutaneous coronary intervention, emergency coronary artery bypass grafting and thrombolytic therapy with urokinase and other drugs. At the same time, during the course of the disease, it is necessary to closely monitor the condition, observe whether there is a combination of right ventricular myocardial infarction, and if necessary, carry out rehydration and dilation and other anti-shock treatment. It is recommended that the patient seek medical treatment in time. The use of specific drugs should be under the guidance of a doctor.
