What does myocardial infarction mean

Myocardial infarction is a serious cardiovascular disease, the main symptoms include chest pain, dyspnea, etc., high-risk groups include hypertension, hyperlipidemia, diabetes and other patients, diagnostic methods include electrocardiogram, myocardial enzyme examination, etc., treatment methods include drug therapy, interventional therapy, thrombolytic therapy, etc., preventive measures include healthy lifestyle, control risk factors, etc. Myocardial infarction is a serious cardiovascular disease, also known as myocardial infarction. It is caused by the rupture of atherosclerotic plaques in the coronary arteries, leading to thrombosis, blocking the coronary arteries, causing ischemia, hypoxia, and necrosis.The main symptoms of myocardial infarction include: 1. Chest pain: Severe, crushing pain, usually in the chest, that may radiate to the left shoulder, left arm, neck, or back. 2. Dyspnea: feeling shortness of breath or difficulty. 3. Sweating: excessive sweating, especially in the chest. 4. Nausea, vomiting: may be accompanied by upper abdominal pain. 5. Fatigue, weakness: feeling very tired and weak. 6. Palpitations: irregular heartbeat or rapid heartbeat. High-risk groups for myocardial infarction include: 1. hypertension. 2. hyperlipidemia. 3. Diabetics. 4. Smokers. 5. Obese. 6. People with a family history of cardiovascular disease. 7. Older people. Myocardial infarction is usually diagnosed by the following methods: 1. Electrocardiogram: Recording the electrical activity of the heart to help detect signs of myocardial infarction. 2. Myocardial enzyme test: Detection of levels of specific enzymes in the blood to determine if the heart muscle is damaged. Coronary angiography: A catheter is inserted into a coronary artery to observe the condition of the vessel and determine the location and extent of the blockage. Treatment for myocardial infarction includes: 1. Drug therapy: Use of drugs to relieve symptoms, reduce mortality, and prevent complications. 2. Interventional therapy: To open blocked blood vessels by percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). Thrombolytic therapy: Use thrombolytic drugs to dissolve clots and restore blood flow. Prevention measures for myocardial infarction include: 1. Healthy lifestyle: maintain a balanced diet, moderate exercise, quit smoking and limit alcohol. 2. Control risk factors: Such as hypertension, hyperlipidemia, diabetes, etc. 3. Regular physical examination: timely detection and treatment of cardiovascular disease. 4. Follow the doctor's advice: take medicine on time, regular review. For patients with myocardial infarction, time is life. once suspected symptoms appear, call the emergency telephone or go to the hospital emergency department immediately. Early treatment can improve survival and quality of life. In short, myocardial infarction is a serious disease that needs to be taken seriously. Understanding the symptoms of myocardial infarction, high-risk groups, diagnosis and treatment, and taking preventive measures can help us better protect our heart health. If you or someone close to you has symptoms of myocardial infarction, please seek medical attention promptly.
