Is inferior myocardial infarction serious?

Inferior wall myocardial infarction is not a very serious disease, but during the acute onset, the heart needs to maintain normal movement, so it may make people feel uncomfortable at ordinary times and requires monitoring and a certain quality of life. When necessary, the patient also needs continuous oxygen inhalation to ensure the normal beating of the heart and normal aerobic transport in the body.

Treatment

Treat aura symptoms promptly and aggressively

The onset of prodromal symptoms may be a sign of an impending myocardial infarction. It is advisable to advise patients to be hospitalized and to take timely and active measures to treat myocardial infarction, which can reduce the chance of myocardial infarction in these patients. [2]

Treatment of acute myocardial infarction

During this period, the treatment principle should be to protect and maintain heart function, save dying myocardium, prevent the expansion of infarction, reduce the scope of myocardial ischemia, and deal with various complications in a timely manner. We strive to ensure that patients not only survive the acute and dangerous stage, but also retain more functional myocardium after recovery and maintain a more effective life.

Acute myocardial infarction occurs suddenly and should be detected and treated early, with strengthened pre-hospitalization treatment. The principles of treatment are to save the dying myocardium, reduce the area of ​​infarction, protect heart function, and deal with various complications in a timely manner.

1. Monitoring and general treatment

For patients without complications, they should stay in bed for 1 to 3 days during the acute phase; receive oxygen; and undergo continuous ECG monitoring to observe changes in heart rate, heart rhythm, blood pressure, and respiration. For patients with hypotension or shock, capillary wedge pressure and venous pressure should be monitored when necessary. Low salt, low fat, eat small meals frequently, and keep bowel movements regular. After 3 days, patients without complications gradually transitioned to sitting in a chair next to the bed to eat, urinate, and move around indoors. Patients can usually be discharged from the hospital within 2 weeks. For patients with heart failure, severe arrhythmias, hypotension, etc., the bed rest time and discharge time need to be extended as appropriate.

2. Sedation and analgesia

Small doses of intravenous morphine are the most effective analgesic; pethidine can also be used. Those who are irritable and nervous can be given diazepam (Valium) orally.

3. Adjust blood volume

Establish intravenous access as soon as possible after admission, and slowly replenish fluids in the first 3 days, paying attention to the balance of intake and output.

4. Reperfusion therapy to reduce infarct area

Reperfusion therapy is the main treatment measure for acute ST-segment elevation myocardial infarction. Opening the blocked coronary artery and restoring blood flow within 12 hours of onset can reduce the area of ​​myocardial infarction and reduce mortality. The earlier the coronary artery is reopened, the greater the benefit to the patient. "Time is myocardium, time is life." Therefore, a diagnosis must be made as soon as possible for all patients with acute ST-segment elevation myocardial infarction, and a reperfusion therapy strategy must be developed as soon as possible.

(1) Primary coronary intervention (PCI)

In hospitals with emergency PCI conditions, if the first balloon dilatation can be completed within 90 minutes of the patient's arrival at the hospital, all patients with acute ST-segment elevation myocardial infarction within 12 hours of onset should undergo direct PCI treatment, with balloon dilatation to reopen the coronary artery and stent placement if necessary. In the acute phase, only the infarct-related artery is treated. Patients with cardiogenic shock should be treated with direct PCI regardless of the onset of the disease. Therefore, patients with acute ST-segment elevation myocardial infarction should seek treatment in a hospital with PCI facilities as much as possible.
