Before a heart attack, these disservices can’t help!


My heart hurts!

Feeling breathless and dizzy…

Chest tightness, chest pain, difficulty breathing, and may also be accompanied by restlessness, profuse sweating, dizziness, and extreme fear.

If this happens, it is likely to be a heart attack!

01. What’s the matter with myocardial infarction?

Myocardial infarction, also known as myocardial infarction, is like our heart is a blood pump that works increasingly every day to deliver blood to all parts of our body . However, the important part that determines the continuous operation of the pump is the coronary artery (blood vessel) on the heart, which is like the power supply wire on the pump, which supplies blood to the heart pump.

Once the coronary arteries are blocked, like a problem with the wires, the blood pump can’t work properly, then our whole body is bad, the blood pressure is gone, and the blood doesn’t flow. Fresh oxygen cannot be delivered, and every cell in the body is forced to strike or even die. This means that patients with myocardial infarction often have a feeling of imminent death when they have an attack.

02. Know the misunderstanding of first aid!

Myocardial infarction is like stepping into hell. Therefore, in rescuing patients with myocardial infarction, every minute is precious. Before the arrival of the ambulance, the following disservices, we cannot help!

First, do CPR!

Myocardial infarction patients will fall to the ground with chest pains when they have a heart attack. In this situation, they may think of the drama on TV when they panic, and perform CPR to the patient by pressing the chest.

Chest compressions are intended for patients in cardiac arrest, provided that the patient is unconscious, breathing weakly, and has an unintelligible pulse if

strong>Chest compressions on a conscious person may be counterproductive.

Second, pick up the patient immediately and give water!

Someone will rush the patient up and sit down, give two sips of water, and pat the back. Doing so will kill you!

In acute myocardial infarction, the blood vessels of the heart itself are ischemia. At this time, if the patient is asked to stand up or sit up, the tired heart has to spend more effort to supply blood to other places, giving the heart’s Blood volume will naturally be less.

Third, give patients nitroglycerin indiscriminately!

Patients have a sudden myocardial infarction, and many family members are very anxious, and will immediately give the patient nitroglycerin, but not everyone can eat it, nor can it be eaten with water, let alone several times in a row. film!

Continuously taking nitroglycerin for a short period of time is very dangerous and does not reduce mortality. It may cause blood pressure to drop. At this time, time is wasted to observe the effect after taking the medicine (and it is also continuously administered), and it is easy to miss the best time for rescue!

Fourth, let the patient go to the hospital alone!

After a myocardial infarction, some patients try to go to the hospital by themselves, or even drive to the hospital by themselves. This practice is a taboo in the management of myocardial infarction!

Blind movement after a myocardial infarction can aggravate myocardial ischemia and lead to cardiac arrest at any time. At this time, if there is no accompanying person around, it is very easy to miss the golden time for treatment.

First aid measures before the arrival of 03 and 120

“Time is myocardium and time is life”

What should I do before the ambulance arrives? How to seize the best time for emergency treatment in patients with acute myocardial infarction?

First Aid

First, let the patient rest on the spot, lie supine with the head slightly lower, if there is foreign body in the oral cavity, it needs to be cleaned in time to keep the airway unobstructed, and avoid The foreign body in the patient’s mouth choked on the trachea.

Second, if the patient is unconscious, CPR should be performed.

Third, if the patient’s blood pressure is not low, and there is a history of myocardial infarction or angina pectoris in the past, 1 capsule of nitroglycerin can be given under the tongue for 5-10 minutes when there is chest pain. The effect can be taken with another pill. Remember not to overuse nitroglycerin.

Fourth, if there is an oxygen bottle at home, let the patient inhale oxygen as soon as possible, which can increase myocardial oxygen supply and relieve symptoms.

Fifth, when the patient is alone at home, don’t lock the door, just lie down and wait for rescue.
