How to give first aid to sudden myocardial infarction? The doctor teaches you a set of emergency measures

 What's going on with a heart attack?

We often see people in movies and TV dramas, covering their chest and shouting "I have a heart attack". Here "heart attack" refers to myocardial infarction. Myocardial infarction is an acute attack of severe coronary heart disease, myocardial infarction patients with coronary artery lesions often exist for a long time, the affected coronary artery branch lumen in the onset of serious blockage or completely closed, the corresponding myocardial blood supply sharply reduced or even interrupted, for a long time will lead to myocardial necrosis and accompanied by severe chest pain and other symptoms, not timely rescue the patient is easy to occur Sudden cardiac death.

First judge whether it's myocardial infarction

Acute myocardial infarction is a sudden disease, everyone should understand its symptoms and make timely judgment. Although it may not be accurate, considering the high mortality rate of myocardial infarction, it is better to "misjudge 3000" than to "miss one".

We all know that "myocardial infarction can cause chest pain", but this understanding is still superficial. Myocardial infarction often has the following characteristics

1. There are often causes of attack

Most of them occur after strenuous activities, sudden exertion, emotional excitement, being frightened, having enough to eat and getting cold suddenly.

2. Typical symptoms are chest pain and tightness

The most typical symptom of myocardial infarction is the feeling of "stuffy pain" in the chest. Some people may have only chest tightness or chest pain and dyspnea.

In addition, there may be restlessness, sweating, dizziness, extreme fear and other symptoms.

3. Other parts of the body also hurt

The area of pain is usually the chest. Generally, the pain range is about the size of a palm. However, some people may show discomfort in the whole chest, even in the shoulder, left arm, neck, teeth and other parts.

Deep color is the place where pain and discomfort may appear

4. Onset time

Typical myocardial infarction generally lasts for more than 5 to 15 minutes. Generally speaking, if chest pain lasts for 20 minutes, it is highly suspected that it is myocardial infarction. Therefore, as long as chest pain lasts for more than five minutes, it is necessary to be highly vigilant.

5. These people are more likely to have a heart attack

Myocardial infarction is more common in middle-aged and elderly people, and people with smoking, diabetes, hyperlipidemia and obesity are more likely to have myocardial infarction.

Myocardial infarction is a very serious disease, if the rescue is not timely, there may be life-threatening, and many patients with myocardial infarction are outside the hospital, the probability of having a cardiologist is almost zero, if the people around know some first-aid knowledge, they can win time for patients with myocardial infarction, then, what about sudden myocardial infarction?

Sudden myocardial infarction family how to do?

1. Call 120 for help

Angina pectoris is a typical symptom of myocardial infarction. Once myocardial infarction occurs, the patient should immediately dial 120 emergency call to wait for the arrival of the ambulance.

2. Rest in place

When waiting for the 120 ambulance to arrive, patients with myocardial infarction can rest in place. It is better to let the patient lie flat and keep quiet, and do not let the patient be stimulated. If there is oxygen at home, the patient can be given oxygen. If there is no oxygen in the home, the window should be opened, and the people around the patient should be dispersed, so that the patient can get sufficient oxygen inhalation.

3. Artificial respiration

If ventricular fibrillation occurs in patients with myocardial infarction, it may lead to sudden death. Therefore, in addition to keeping the respiratory tract of patients with myocardial infarction unobstructed, chest compression and artificial respiration should also be given to patients to prevent brain death due to cerebral hypoxia. When doing artificial respiration, let the patient lie on his back, face up, put a soft pillow on the back of his neck, and let the patient's head lean back as far as possible. The rescuer should hold the patient's nose and blow air into the patient's mouth with his mouth, about 12 times per minute. During artificial respiration, you should also touch the patient's artery. If there is no pulse, you should also massage the heart at the same time.

4. Sublingual nitroglycerin

If the patient has coronary heart disease, and now suspects that the patient may have myocardial infarction, the patient can take nitroglycerin sublingually, or Suxiao Jiuxin Pill, Danshen dripping pill and other drugs sublingually for emergency treatment. It should be noted that nitroglycerin can only be taken one tablet at a time, and the symptoms can not be relieved. After five minutes, nitroglycerin can be taken again, and the continuous medication can not exceed three tablets at most.

If you can master some first-aid knowledge of myocardial infarction, when someone around you has a myocardial infarction attack, actively take some first-aid measures, you can let the patients with myocardial infarction win the God of death.

Note: Nitroglycerin should not be eaten casually

Nitroglycerin is widely used in the treatment of coronary heart disease and heart failure because of its mechanism of action in the treatment of heart disease, such as reducing the load of the heart, reducing the work of the heart (equivalent to decompressing the heart), directly expanding the coronary artery, protecting ischemic myocardial cells and so on.

Nitroglycerin can not be taken indiscriminately even if coronary heart disease is definitely diagnosed

1) Hypotension state, blood pressure below 90 / 60mmhg, generally can not take;

2) Angina pectoris caused by other diseases, such as aortic stenosis, hypertrophic obstructive cardiomyopathy, etc;

3) Severe bradycardia;

4) Glaucoma;

5) Patients with sexual dysfunction and taking sildenafil (Viagra).
