Myocardial infarction is a relatively common critical illness in our daily lives. Many patients often delay their condition severely due to untimely treatment, which becomes an important cause of disability and death. So how should myocardial infarction be treated? It should be treated from the following two aspects: First, acute myocardial infarction. For acute myocardial infarction, it is necessary to promptly open the occluded blood vessels, restore cardiac perfusion, and save viable myocardium. This can be achieved through emergency interventional treatment or thrombolytic therapy. Second, old myocardial infarction. At this time, treatment mainly involves taking oral aspirin and statins to stabilize the disease and prevent the condition from worsening or deteriorating. (Medication should be used under the guidance of a professional doctor.)

How long does the pain from a myocardial infarction last?

Acute myocardial infarction often develops from angina pectoris. When angina persists for more than 30 minutes, myocardial necrosis begins. After the myocardial necrosis, symptoms similar to those of a burn appear, such as reddening of the myocardium, blistering, and necrosis. Generally speaking, these symptoms last no less than three days. Many people experience significant improvement after three days because the area of myocardial infarction is relatively small. In patients with extensive myocardial infarction, symptoms can last for 7 days or even longer. During this time, patients may also experience respiratory difficulties, recurrent chest pain, and even sudden death. Therefore, the duration of symptoms in myocardial infarction generally ranges from 3 to 7 days. If there is no improvement within this period, the disease might have led to severe complications.

Heart attack is what disease

Myocardial infarction is a serious heart condition caused by the formation of atherosclerotic thrombosis in the coronary arteries, blocking the blood vessels that supply the heart muscle and leading to myocardial necrosis. Timely rescue treatment is necessary, and without effective treatment, it can lead to serious complications. Common complications include heart failure, cardiogenic shock, and arrhythmias, which can be life-threatening. Therefore, after a myocardial infarction occurs, it is essential to immediately go to the hospital for rescue treatment, using effective medications to promote blood circulation, remove blood stasis, dilate the coronary arteries, and improve myocardial blood supply, among other treatment methods.

Is vomiting severe in myocardial infarction?

Patients with myocardial infarction often have a history of hypertension, coronary heart disease, and diabetes. They usually experience repeated episodes of angina. After angina, the chest pain persists and cannot be alleviated, often including feelings of chest oppression and pressure. Some patients may also experience nausea, vomiting, and fainting, but most do not have severe vomiting. Some patients, because of inferior wall myocardial infarction or posterior wall myocardial infarction, may develop right ventricular dysfunction, or during the treatment process, due to decreased appetite, may suffer from severe vomiting caused by low potassium and low sodium levels. However, this can generally be corrected through treatment.

Can myocardial infarction recover?

After a myocardial infarction occurs, the myocardium cannot return to its original state. Thus, the heart itself also constrains the overall state of the body, and the whole body can no longer return to its original state. Myocardial infarction means the necrosis of myocardial cells. The heart itself loses some of its myocardial function, and after losing part of the myocardium, myocardial remodeling occurs. These changes act as compensation, and through aggressive treatment, the function of the remaining myocardium can be preserved to the greatest extent. If a myocardial infarction occurs, immediate interventional treatment or thrombolytic therapy can prevent myocardial cell necrosis, or even make it minimal. In this case, the heart as a whole is nearly normal, and its function is unaffected. The larger the area of myocardial necrosis, the less remaining function the heart has. If the area affected by the myocardial infarction is relatively small, and with aggressive, long-term treatment, the function of the heart can be preserved to the greatest extent. Thus, the prognosis is generally better. The larger the area of myocardial infarction, the worse the prognosis.

Complications of myocardial infarction

Myocardial infarction is a more serious disease of the heart. Suffering from myocardial infarction can cause significant harm to the body and, in severe cases, can be life-threatening. If not properly treated, it can lead to various complications. The most common complications include arrhythmias, heart failure, cardiogenic shock, rupture of the ventricular wall, papillary muscle rupture, and ventricular septal perforation. Therefore, once a myocardial infarction occurs, it is crucial to actively perform rescue operations and treatments to prevent the occurrence of these complications.
