What are the symptoms of myocardial infarction

summary

Acute ischemic necrosis of the heart is called myocardial infarction. This disease is based on coronary artery disease. When coronary artery disease occurs, the blood flow will decrease rapidly, and finally lead to the decrease of myocardial blood supply, or the middle of myocardial blood supply, and finally severe myocardial ischemia and hypoxia, leading to acute myocardial ischemic necrosis. After the onset of myocardial infarction, patients with severe pain behind the sternum, severe fever, the number of white blood cells increased significantly, and the content of serum myocardial enzymes increased rapidly. ECG can reflect the presence of acute myocardial injury in patients. What are the symptoms of myocardial infarction

What are the symptoms of myocardial infarction

Chest pain: chest pain is a typical and common symptom of myocardial infarction. But not all patients with myocardial infarction will have chest pain symptoms, and chest pain may not be caused by heart disease. Chest pain associated with the heart is usually concentrated behind the sternum, or in the middle to the left. Abnormal pain often occurs when it is quiet and does not hurt after rest, which is particularly easy to ignore. This kind of symptom is likely to cause sudden myocardial infarction within 1-2 days or even within a week. We should be alert and go to the hospital in time to prevent accidents.

Sudden sweating, pale face: feel unwell, accompanied by cold sweat or sweating, or pale face, often feel restless, anxious or near death, may be the precursor of myocardial infarction.

Fatigue: female, at the onset of myocardial infarction or before the onset of fatigue symptoms may appear. This kind of fatigue is probably the manifestation of heart failure. But how can we tell whether it's fatigue caused by myocardial infarction or other causes? Xiaotie suggests that you should see a doctor in time to avoid missing the best treatment time.

matters needing attention

The key to reduce mortality is to dredge the blocked coronary artery and let the heart regain blood supply. The ideal time to open the blood vessel is within 120 minutes after the onset of the disease.
