In many film and television dramas, we can see such a plot: when the characters in the play are stimulated, they often have a heart attack, at this time, their faces usually change, and then they cover their chests and fall to the ground. But in real life, acute myocardial infarction is different from acting in film and television dramas, and for many patients with acute myocardial infarction, they don't even realize that they have a myocardial infarction.

From a clinical point of view, profuse sweating and chest tightness and chest pain are the most typical symptoms of patients with acute myocardial infarction, and this symptom usually occurs suddenly in a quiet environment. In general, pain tends to start in the precordium or behind the sternum and can range about the size of a palm. Patients describe the pain as usually as a crunch, cramp, or squeezing pain.

Others said it felt like a big rock had been placed in their chest. Unlike the plot of the TV series, most acute myocardial infarctions do not pass out immediately after the onset of the disease, and in general, many patients have more than 15 minutes of onset, and even worse, it may last for more than a few hours.

In fact, although the onset of acute myocardial infarction is relatively rapid, there are often some aura manifestations hours or days before the onset of acute myocardial infarction. Clinically, patients often have 5 aura before acute myocardial infarction comes.

1. Discomfort in the neck or throat

Before a heart attack, many people experience throat or neck discomfort, while others experience a feeling of blockage in their throat. In addition, some patients may also sweat profusely.

2. Pain in the upper limbs

In the case of cardiac ischemia, the person may experience pain in the upper limbs, which may radiate to the inside of the left arm, left shoulder, and little finger. In fact, this is also a typical precursor before a heart attack, and everyone must pay more attention to it on weekdays.

3. Back pain

For some people with a myocardial infarction, the pain may also radiate to the back, causing persistent back pain. Women are more likely to experience this symptom than their male friends.

4. Epigastric pain

Some patients with a myocardial infarction may mistake the symptoms of chest pain for stomach pain, but in fact, this is mainly because before the onset of a myocardial infarction, the patient's upper abdomen and around the navel may experience a burning sensation and pressure, in this case, it is often easy for us to misjudge the location of the pain.

5. Toothache

For a small percentage of patients, a toothache may also occur before a heart attack, and in this case, patients often cannot say which toothache it is.

Although patients may experience the above 5 symptoms before the onset of acute myocardial infarction, this does not mean that as long as these symptoms appear, it is necessarily a sign of imminent myocardial infarction. Seeing this, some people may ask: what should I do if I have these symptoms and I suspect that I have a heart attack? In fact, in the face of this situation, the right thing to do is to go to the hospital for a check-up in time and seek help from a doctor in time. Only in this way can you understand your physical condition in detail and find out the cause.
