Myocardial infarction refers to a disease caused by insufficient or blocked coronary artery blood supply leading to ischemic necrosis of the myocardium. It is usually a serious form of coronary heart disease, which is caused by sustained ischemia and hypoxia of the heart muscle tissue.
1、 The premonitory symptoms of myocardial infarction
1. Chest pain: The most common symptom of myocardial infarction is chest pain, usually presenting as a persistent or persistent sense of compression. This pain can radiate to the left arm, neck, jaw, back, or upper abdomen, similar to severe chest tightness or tightness.
2. Dyspnea: Myocardial infarction may also lead to breathing difficulties, such as shortness of breath or feeling suffocated. This is caused by insufficient oxygen supply in the body due to cardiac dysfunction and circulatory failure.
3. Nausea and vomiting: Some patients with myocardial infarction may experience symptoms of nausea and vomiting in the early stages of the disease. This may be due to gastrointestinal reactions caused by impaired heart function.
4. Fatigue and fatigue: Patients with myocardial infarction often feel abnormally tired and fatigued, which cannot be relieved even after mild activity or rest. This is caused by insufficient blood supply to the heart, leading to hypoxia in various tissues and organs of the body.
5. Cold sweat and wet cold sensation: Sometimes, patients with myocardial infarction may experience symptoms of increased sweating, cold sweat, and wet cold sensation. This may be an autonomic nervous response produced by the body in response to heart disease.
6. Panic and anxiety: Myocardial infarction can cause feelings of palpitations and anxiety. This may be due to insufficient blood supply to the heart, causing people to experience tension, anxiety, and fear.
2、 Prevention and treatment methods for myocardial infarction
1. Maintain a healthy lifestyle: eat a healthy diet, choose low salt, low-fat, and low cholesterol foods, increase intake of fruits, vegetables, whole grains, and foods rich in healthy fats (such as fish, nuts, and olive oil).
2. Moderate exercise: Regularly engage in aerobic exercise such as brisk walking, jogging, cycling, etc., while also conducting moderate strength training.
3. Quit smoking and limit alcohol consumption: Try to avoid smoking and excessive drinking, and avoid exposure to secondhand smoke as much as possible.
4. Control of hypertension, hyperlipidemia and diabetes: measure blood pressure regularly. If there is hypertension, actively treat it and control the blood pressure target. Regularly test the blood lipid level. If there is hyperlipidemia, reasonably control the diet and, if necessary, take medication to control the blood sugar level. If there is diabetes, actively carry out diet control, moderate exercise and medication.
5. Pay attention to mental health and coping with stress: Learn to cope with and reduce stress, such as regular rest, relaxation training, and participating in soothing activities.
6. Regular physical examinations and screenings: Regular physical health checks are conducted, including testing of blood pressure, blood lipids, blood sugar, and other indicators.
7. Electrocardiogram examination: Regular or irregular electrocardiogram examination is performed to observe cardiac function and abnormal signs.
8. Cardiac ultrasound examination: If necessary, perform cardiac ultrasound examination to evaluate the structure and function of the heart.
9. Follow medical advice to use medications: Antiplatelet drugs such as aspirin can prevent thrombosis, antihypertensive drugs such as beta blockers and calcium channel blockers can control blood pressure and reduce cardiac load, cholesterol lowering drugs such as statins can help lower cholesterol levels in the blood.
10. Surgical treatment: Coronary artery bypass surgery, suitable for patients with severe coronary heart disease leading to myocardial ischemia. Percutaneous coronary intervention surgery involves implanting a stent through a catheter to dilate the narrowed coronary artery and restore blood flow.
11. Seek medical attention and emergency treatment in a timely manner: If symptoms of myocardial infarction occur (such as severe chest pain, difficulty breathing, cold sweat, etc.), immediately call the emergency number and go to the hospital for treatment.
Myocardial infarction is a serious cardiovascular disease that can lead to fatal consequences. Therefore, the importance of preventive measures cannot be ignored. By adopting healthy lifestyles, rational drug treatment, and regular check ups, the risk of myocardial infarction can be reduced. At the same time, early identification and timely intervention are also crucial.
