Myocardial infarction is a relatively common disease in daily life, and it also poses a serious threat to people's health and safety. The symptoms of a myocardial infarction mainly include the following aspects: First, severe chest pain, which is often the most common symptom of myocardial infarction, typically feels like a crushing sensation or is accompanied by a feeling of impending doom. Second, symptoms of heart failure, which, when myocardial infarction is complicated by heart failure, often manifest as difficulty breathing and profuse sweating. Third, symptoms of arrhythmia, which, when myocardial infarction is complicated by arrhythmia, often presents with symptoms like palpitations and dizziness.

What is good to eat for myocardial infarction?

After suffering from myocardial infarction, it is necessary to use effective drug treatments under the guidance of a doctor, and at the same time, dietary structure should be appropriately adjusted. Consume easily digestible foods and avoid spicy and greasy foods. You can eat some foods containing high-quality protein, high vitamins, and high trace elements, such as milk, eggs, lean meat of animals, and sea cucumber. These foods contain high-quality protein, which can enhance immunity and promote the repair of myocardial tissue. Consume more vegetables containing crude fiber, such as celery, spinach, and winter melon. These vegetables can not only supplement trace elements and vitamins but also help in easing bowel movements, relieving constipation, and reducing the burden on the heart. Focus on consuming green leafy vegetables. For fruits, choose kiwi, grapefruit, and oranges which are rich in vitamin C and potassium. Avoid smoking and drinking alcohol, and avoid strong tea, coffee, and foods that are too cold, too hot, spicy, or stimulating.

What should be noted in daily life regarding myocardial infarction?

Myocardial infarction is a serious heart disease caused by coronary artery narrowing and blockage, leading to myocardial ischemia and hypoxia, and necrosis, particularly in cases of extensive myocardial infarction. If not effectively treated, it can lead to severe complications such as heart failure, cardiogenic shock, and arrhythmias. Therefore, it is essential to follow a doctor's guidance and use effective medications for emergency treatment. In daily life, it is important to maintain a pleasant mood, avoid irritability, consume easily digestible food, quit smoking and drinking, and primarily follow a low-fat, low-salt diet to keep the bowel movements regular. This helps prevent worsening of the condition due to improper diet and constipation, which can increase the cardiac burden.

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.

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.

How is myocardial infarction treated?

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.)
