What is myocardial infarction in the lower wall, how to do

Inferior myocardial infarction refers to acute myocardial infarction of inferior wall, which is mainly caused by reduced blood perfusion in heart, insufficient myocardial oxygen supply and increased myocardial oxygen consumption. 1. Decreased blood perfusion in the heart If you suffer from coronary atherosclerosis, coronary spasm, coronary microcirculation dysfunction and other diseases, resulting in reduced blood supply to the branches of the right coronary artery, resulting in insufficient myocardial blood supply to the lower wall of the heart, it will cause acute myocardial infarction in the lower wall. 2. Insufficient myocardial oxygen supply If bradyarrhythmia, respiratory failure, severe anemia and other diseases occur, resulting in insufficient myocardial oxygen supply, resulting in myocardial damage and necrosis of the lower wall, it will cause acute myocardial infarction of the lower wall. 3. Increased myocardial oxygen consumption If you suffer from coronary heart disease, persistent tachyarrhythmia, severe hypertension and other diseases, resulting in myocardial oxygen consumption exceeding the body's oxygen supply, resulting in damage to the lower wall myocardium, it will cause the phenomenon of acute myocardial infarction in the lower wall. Acute myocardial infarction in the lower wall is mainly treated by general treatment, drug treatment, surgical treatment, etc. 1. General treatment can keep bed rest in absolute quiet environment, monitor the condition in real time and take oxygen inhalation, so as to alleviate the hypoxia of inferior myocardium to a certain extent. 2. Drug treatment is mainly aimed at the etiology, such as acute myocardial infarction in the inferior wall caused by reduced blood perfusion in the heart. Nitroglycerin, isosorbide mononitrate, sodium nitroprusside and other drugs to dilate coronary arteries can be taken. 3. Surgical treatment For patients with severe inferior acute myocardial infarction, percutaneous coronary intervention or emergency coronary artery bypass grafting is usually adopted.
