Acute myocardial infarction: chest pain and chest tightness last for more than 4 hours.
Introduction: Acute myocardial infarction is a serious manifestation of coronary artery disease, and its symptoms of chest pain and tightness can last for more than 4 hours. This article will provide an in-depth analysis of the pathogenesis, clinical manifestations and methods of this disease to help you understand this life-threatening disease.
1. Causes of acute myocardial infarction.
Acute myocardial infarction is caused by the blockage of the coronary arteries, resulting in myocardial ischemia, hypoxia, and eventually myocardial necrosis. The coronary arteries are the main blood vessels that supply blood to the heart and are responsible for delivering oxygen and nutrients to the heart muscle. When coronary atherosclerosis causes the lining of blood vessels to be rough, clotting factors in the blood tend to accumulate there, forming blood clots and blocking blood vessels. Once the blood vessels are blocked, the blood flow to the heart muscle** decreases dramatically, leading to myocardial infarction.
2. Clinical manifestations of acute myocardial infarction.
The typical symptoms of acute myocardial infarction are chest pain and tightness, which can last for more than 4 hours. Chest pain is usually located in the posterior part of the sternum and can radiate to the left shoulder, arm, neck, and jaw. The pain is intense, with a feeling of pressure, tightness, and sometimes sweating, nausea, and vomiting. Chest tightness is also a common symptom, with patients feeling heavy in the chest and having difficulty breathing.
In addition, acute myocardial infarction may also present with some atypical symptoms, such as epigastric pain, toothache, neck pain, etc. These symptoms can be easily confused with other diseases, leading to misdiagnosis. Therefore, if you have suspected symptoms, you should seek medical attention promptly.
3. The best method of acute myocardial infarction.
The principle of acute myocardial infarction is to restore blood to the heart as soon as possible, reduce myocardial damage, and improve heart function. **Methods mainly include drugs**, intervention**, and surgery**.
1.Drugs**: After arriving at the hospital, the doctor will give corresponding drugs** according to the condition, such as thrombolytic drugs, antiplatelet drugs, anticoagulant drugs, etc. These medications help dissolve blood clots, restore blood to the heart**, and prevent further deterioration of the condition.
2.Intervention**: For patients who do not respond well to drugs or are seriously ill, intervention** can be used. Interventions** mainly include coronary angiography, coronary interventional surgery, and coronary artery bypass surgery. Through intervention**, doctors can directly observe the blockage of coronary arteries and take corresponding measures, such as placing stents and opening bypasses, to restore blood to the heart**.
3.Surgery**: Surgery may be required in patients with severe myocardial infarction**. Surgeries** mainly include coronary artery bypass surgery and resection of the myocardial infarction area. These surgeries can help improve heart function and reduce mortality.
4. Measures to prevent acute myocardial infarction.
Acute myocardial infarction is a serious condition, and prevention is crucial. Here are some precautions:
1.Control risk factors: hypertension, hyperlipidemia, diabetes, and smoking are all risk factors for acute myocardial infarction. By controlling these risk factors, the risk of disease can be reduced.
2.Healthy Diet: Maintain a balanced diet with plenty of vegetables, fruits, and whole grains, and reduce your intake of greasy, high-calorie, high-sugar foods.
3.Moderate exercise: Maintaining a moderate amount of aerobic exercise, such as walking, running, swimming, etc., can help improve cardiopulmonary fitness and reduce the risk of disease.
4.Quit smoking and limit alcohol: Smoking and alcohol consumption are harmful to heart health, so you should quit smoking and limit alcohol as soon as possible.
5.Mental balance: Maintain a good mindset and avoid excessive stress and anxiety.
6.Regular physical examination: Regular physical examination is carried out to detect and develop hypertension, hyperlipidemia, diabetes and other diseases in time.
Conclusion: Acute myocardial infarction is a serious disease, and chest pain and chest tightness lasting for more than 4 hours are its typical symptoms. By understanding the causes, clinical manifestations, and methods, we can better prevent and respond to the disease. In daily life, it is necessary to maintain a healthy lifestyle and seek medical attention in time to reduce the risk of acute myocardial infarction. Let's focus on heart health and protect the source of life.
