What is a heart attack?

A heart attack (myocardial infarction) is a condition where blood flow decreases or stops to a part of the heart. It may happen due to a blockage of blood vessels, which harms the part of the muscle that no longer gets oxygen from the blood. If the blockage is not removed within a few hours, the part of the heart muscle will begin to die.

Causes of a heart attack

The researchers state that the following risk factors may lead to heart attacks in 90% of all cases:

  • smoking;
  • stress;
  • increased cholesterol in the blood;
  • obesity (for example, alimentary);
  • diabetes;
  • low level of physical activity (lack of exercise);
  • high blood pressure.

What is a sudden cardiac arrest?

Cardiac arrest is a sudden electrical malfunction in the heart which leads to irregular heartbeat, resulting in the loss of blood flow. Due to impaired pump function of the heart, one’s brain, lungs, kidneys and other organs stop receiving blood. Blood pressure drops almost instantly, and collapse can lead to the death of a person in just a few minutes.

The main causes of cardiac arrest:

  • coronary artery disease;
  • heart attack;
  • cardiomyopathy;
  • congenital heart diseases.

The most characteristic symptoms of cardiac arrest are:

  • dizziness;
  • loss of consciousness;
  • sudden drop in blood pressure;
  • pulse deficit;
  • absence of respiration (apnea);
  • cyanosis of the face.

It is necessary to call an ambulance and immediately begin performing cardiopulmonary resuscitation (CPR). If there is an automatic external defibrillator, you need to use it as soon as possible. A sudden cardiac arrest can lead to death in a few minutes if a person doesn’t receive immediate medical help.
