According to statistics, more than half of the patients who died of myocardial infarction were not properly rescued before arriving at the hospital.

The golden time for the rescue of myocardial infarction is the short one hour after the onset of illness. However, some erroneous rescue methods will not only fail to save lives, but will even worsen. Here we will take a look at the four “must not do” and four “must do” when the heart attack occurs.

Four “Must not do”

1. Do not go to the hospital alone

This may be the most common and also the most erroneous and dangerous practice. It is good to know that going to the hospital with the disease, but it is a matter of life if you have to go to the hospital alone.

First, go to the hospital, register and check on the road. These processes are tossing people in today’s big hospitals, which may lead to deterioration of the disease.

Second, if no one is around, in the event of a cardiac arrest, it is very likely that the best time for rescue will be missed.

Suspect your heart attack, must not go to the hospital alone. In this case, any slight activity will increase the burden on the heart. It may be fine for the previous second and it will fall in the next second.

2. Never arbitrarily take nitroglycerin

Nitroglycerin is a familiar drug for treating angina, but it should be used with caution in patients with myocardial infarction. This medicine can dilate blood vessels throughout the body and lower blood pressure.

Therefore, taking nitroglycerin is a contraindication for patients with low blood pressure acute myocardial infarction, it will lead to further lower blood pressure, increase the risk of shock. Even if the blood pressure is normal, be sure to lie down when taking nitroglycerin to prevent orthostatic hypotension and cause dizziness to fall.

3. Do not drink water

You may heard that once an MI occurs, helping the patient to drink water immediately can reduce blood viscosity and relieve symptoms.

Not to mention that this practice is not good for a patient with a normal vital sign. For a patient who has already undergone shock or even a heartbeat and respiratory arrest, it will be even more fatal.

In some cases, the patient’s consciousness is unclear. Drinking water can easily lead to aspiration and inhalation of pneumonia. This is undoubtedly aggravated by patients with MI. In addition, if an infarct patient drinks too much water at a time, the moisture will quickly enter the bloodstream, making the blood thinner and the blood volume increase, adding even more unbearable extra burden to the unhealthy heart.

4. Do not arbitrarily do cardiopulmonary resuscitation

You may heard that in the event of a myocardial infarction, CPR should be performed immediately.

Cardiopulmonary resuscitation is not necessarily unusable, but it is necessary to judge the situation first. This first-aid method is suitable for patients with heartbeat and respiratory arrest, and not all patients with acute myocardial infarction will have no breathing and heartbeat. For those who do not have cardiac arrest, CPR will increase the risk of fatal arrhythmia.

Some people would ask, since this can’t be done,just see the patient’s pain while waiting for the ambulance to arrive?

Of course not.

After the four “must not do”, then four “must do”, the patient and the family must remember the following four points.

Four “must do”

1. Must stop activities

Suspected myocardial infarction, the patient should immediately stop activities, and is any activity. Rest immediately on the spot to avoid outside interference. It is human nature to have an episode of myocardial infarction, but for the stability of the patient’s condition, we still have to stay calm for the first time.

2. Must call emergency phone

At the same time, family members should immediately call the emergency phone and wait for medical personnel to arrive. In the process of waiting, closely observe the changes in the condition and the patient’s vital signs, such as blood pressure, heart rate, breathing, etc., to help doctors understand the situation.

3. Be sure to keep patient breath clear

After stopping the activity, try to keep the patient breathless. If the patient has hypoxic signs, oxygen can be taken, which can quickly improve myocardial ischemia and hypoxia and control or reduce infarct size. If the patient has become unconscious, tilt the patient’s head to one side and clear the mouth and nose of the secretions in time.

4. Must be relieved

Tension does not help the rescue. The family members themselves should not be overly flamboyant. Don’t let their negative emotions affect the patient and add extra psychological burden to the patient. Remember to accompany the patient and wait for the arrival of the ambulance staff.
