Subacute extensive anterior wall myocardial infarction is the stage weeks to months after myocardial infarction that is prone to serious complications such as delayed cardiac rupture due to ventricular wall tumors, and therefore treatment needs to be directed not only at heart failure, but also at preventing these complications. Myocardial infarction is an acute attack disease, if the thrombolytic treatment is not carried out at the time of the disease, then it will be difficult to revascularize later, the treatment can be given to antiplatelet therapy, such as aspirin, clopidogrel, etc.; given to the angiotensin-converting enzyme inhibitors to improve the remodeling of the myocardium, such as captopril, enalapril, etc.; regulating blood lipids, such as simvastatin, etc.. In addition, myocardial infarction is prone to serious arrhythmia, pump failure and complications such as ventricular wall tumor and heart rupture, etc. Antiarrhythmic treatment is given, such as lidocaine, verapamil, etc.; diuretics are used to reduce the afterload of the heart, such as furosemide, etc.; surgical treatment can be performed on patients with the formation of ventricular wall tumor. The above drugs need to be used under the supervision of a doctor. If the diagnosis of subacute extensive anterior wall myocardial infarction is confirmed, please follow the doctor’s instructions to standardize the treatment.
