One person dies from it every minute...If you experience these symptoms in your body, be careful!

Statistics show that the number of people who die suddenly from cardiac causes is as high as 7 million per year, accounting for about 25% of the total number of deaths worldwide. In China, an average of about 544,000 people die suddenly each year, 1,500 people die suddenly every day, and one person dies suddenly every minute, ranking first in the world . The main cause of sudden death is acute myocardial infarction , which accounts for more than 80% of sudden deaths. If rescue is not timely or the rescue method is wrong, it will delay or aggravate the condition and even endanger life. Understanding the ins and outs of acute myocardial infarction is crucial for prevention and emergency treatment. What is acute myocardial infarction?

Acute myocardial infarction is a serious type of coronary heart disease and the main cause of sudden death.

Acute myocardial infarction is a sudden interruption of coronary blood flow on the basis of coronary artery disease. Most of the cases are caused by thrombosis in the coronary arteries, which prevents blood flow, causing persistent and severe ischemia of the corresponding myocardium and even necrosis.

Acute myocardial infarction is a common fatal emergency among middle-aged and elderly people. However, in recent years, acute myocardial infarction has become more and more common among younger people, becoming the number one killer that seriously threatens human life and health.

What are the signs and causes of acute myocardial infarction?

Acute myocardial infarction often has the following signs, which are worth being vigilant about. 1) The frequency of existing angina attacks increases, the pain becomes more severe, and the duration is prolonged, and sublingual nitroglycerin has no obvious effect. 2) Symptoms that have never appeared before appear during angina attacks, such as nausea, vomiting, sweating, palpitations, chest tightness, shortness of breath, etc. 3) Extreme fatigue.

Common causes include:

1) Emotional excitement, such as anger, anxiety, excessive happiness, etc.

2) Physical activities, such as running, climbing stairs, lifting heavy objects, etc.

3) Other reasons, such as heavy smoking, overeating, cold stimulation, etc.

How to identify acute myocardial infarction?

Acute myocardial infarction is more common among middle-aged and elderly people, but in recent years it has become increasingly common among younger people.

Typical manifestations

Pain location: Often when at rest, there is sudden severe pain behind the sternum or in front of the heart, radiating from the left shoulder, left arm or to the back.

Nature of pain: squeezing, compressive, tight or burning pain.

Duration: More than 30 minutes, can reach several hours or even days.

Symptoms: often accompanied by restlessness and fear of movement. May also be accompanied by sweating, nausea, vomiting, fear and a sense of impending death.

Atypical manifestations

No chest pain: Some elderly people, some diabetic patients, and some women do not have chest pain or only feel chest tightness, palpitations, discomfort in the precordial area, etc.

There is no chest pain but upper abdominal pain: accompanied by nausea, vomiting, etc., which can easily be misdiagnosed as acute abdomen.

There is no chest pain, but symptoms include pain in the teeth, throat, jaw, neck, shoulders, back, and arms: rare pain in the head, thighs, and toes, which can easily be misdiagnosed as local lesions such as bones, joints, or soft tissues.

In addition to these conditions, there are also symptoms such as chest tightness, shortness of breath, sweating, cyanosis or pale complexion, irritability, palpitations, and low blood pressure . You must be alert to the possibility of an acute myocardial infarction.

How to provide first aid on the spot when an acute myocardial infarction occurs?

Generally speaking, many people only know that they have "chest pain" and may not be able to distinguish whether an acute myocardial infarction has occurred. The following treatments can be performed:

Absolute bed rest

Maintain a quiet environment, reduce mental stimulation to the patient, and avoid or reduce the movement of the patient. If the patient has difficulty breathing and cannot lie flat, help the patient to sit or semi-recumbent to alleviate the difficulty breathing.

Oxygen 3-5 L/min

It has the dual effects of medical treatment and psychological comfort, and can also increase myocardial oxygen supply and alleviate symptoms.

Call emergency number immediately

Patients with acute myocardial infarction must not go to the hospital by themselves, but must immediately call the emergency number 120. The emergency personnel will do the necessary treatment and decide the time of transfer according to the condition.

Perform CPR immediately

Acute myocardial infarction may cause sudden death at any time. Cardiopulmonary resuscitation should be performed immediately on the spot and an AED (automated external defibrillator) should be used in a timely manner.

How to prevent acute myocardial infarction?

Whether it is hypertension, coronary heart disease, cerebrovascular disease, diabetes, or cancer, these are all lifestyle diseases. Excessive calorie intake, smoking, lack of exercise, obesity, alcoholism, staying up late, sitting for a long time, irritability, psychological pressure, bad marital relationship and other risk factors act on the body, greatly increasing the chance of suffering from these lifestyle diseases.

Maintain a healthy lifestyle

Reject the "three highs" (high salt, high fat, high sugar) and eat a balanced diet.

Exercise properly

Once arteriosclerosis occurs, there is almost no way to reverse it. Moderate exercise can reduce arteriosclerosis and thus reduce the incidence of acute myocardial infarction.

Keep a cheerful mood

Maintain a good attitude at ordinary times, reduce psychological pressure, and avoid being too anxious, nervous or overly excited.
