Inferior wall myocardial infarction is a major problem that requires prompt hospitalization, coronary stenting, thrombolysis, and symptomatic support depending on the condition, and can be life-threatening if not treated in time. Inferior wall myocardial infarction can lead to serious arrhythmia, heart failure and other life-threatening diseases. Therefore lower wall myocardial infarction is a major problem. When an inferior wall myocardial infarction occurs, it is important to go to the hospital promptly. After the doctor evaluates the condition, the following treatments are available. 1. Coronary stenting: within 12 hours of the onset of the disease, the electrocardiogram suggests that there is a new ST-segment elevation or left bundle branch block, the first choice of coronary stenting, and strive for stenting within 90 minutes, in order to save more myocardium. Coronary stenting is also feasible when chest pain and characteristic ECG changes persist for 12 to 48 hours after the onset of symptoms. 2. Thrombolysis: If coronary stenting is expected to take more than 120 minutes after recent bleeding, surgery, or trauma is ruled out, thrombolysis is preferred, using drugs such as urokinase and streptokinase to dissolve the coronary thrombus and restore coronary blood flow. 3. Symptomatic support: such as oxygen, cardiac monitoring, application of antihypertensive drugs for those with low blood pressure, and anti-heart failure treatment for those with heart failure, etc., to stabilize the patient’s vital signs as well as the internal environment, which will help the smooth progress of the operation and the recovery of the disease. When lower wall myocardial infarction is detected, it should not be taken lightly, and should be consulted in time and treated according to medical advice.
