Cardiac arrest, Causes, Symptoms, Hospital Heart failure treatment, Prevention-2021

Cardiac arrest refers to the fact that it is no longer possible for the heart to pump blood to other organs and tissues. Therefore, a cardiac arrest requires immediate first aid to avoid fatal consequences. 

There are several risk factors that can cause it. Let’s take a look.    

In cardiac arrest,

  • A person is unconscious and not breathing normally. The heart no longer pumps blood. This is a life-threatening situation.
  • The heart often does not really stop. But there is something wrong with the electrical system of the heart. The ventricles start to vibrate rapidly and chaotically. 

As a result, the heart can no longer pump blood. As a result, the blood circulation stops. The supply of oxygen and nutrients to the rest of the body stops.

Causes of cardiac arrest:

About half of all people who suffer cardiac arrest are unaware that there is something wrong with their hearts.

The most common cause of a cardiac arrest is a myocardial infarction.

A coronary artery of the heart is blocked and part of the heart no longer receives blood and dies. 

The system that ensures a regular heart rhythm can then become disordered. This can lead to dangerous cardiac dysrhythmia.

Cardiac arrests can also be caused by other heart problems.

For example, heart muscle disease, inflammation of the heart, heart failure, or (hereditary) cardiac dysrhythmia.

Occasionally, a cardiac arrest occurs in a healthy heart. In most cases, it is the result of an accident, such as drowning, hypothermia, or an electrical accident.

[1] Symptoms of cardiac arrest:

In cardiac arrest, there is an acute danger to life. In particular, too little oxygen to the brain quickly causes problems. 

Brain cells are already irreparably damaged after 4 to 6 minutes. After that, other organs are also damaged.

  • What you see:

In cardiac arrest, you lose consciousness within 10 seconds. A person may look a little grey. 

Normal breathing stops. A person may still be gasping for breath. This heavy and noisy breathing is called panting. It is a bit like pulling a fish out of the water. 

  • Prevent cardiac arrest:

Every day 35 people die outside the hospital from cardiac arrest. Often totally unexpected. 

Scientific research is needed to detect and treat dangerous cardiac dysrhythmia at an earlier stage. 

In this way, cardiac arrests can be prevented in the future.

The Heart Foundation encourages people to learn CPR and to register as a civilian aid worker,

[2] Sudden cardiac death in young people:

Regularly there are reports in the media that young people die suddenly, for example during sports. 

It seems to happen often, but in reality, acute cardiac arrest in people under the age of 45 is very rare.

  • Cardiac arrest:

Sudden cardiac death is an unexpected cardiac arrest. The name suggests that the heart stops completely. But this is usually not the case. 

The chambers of the heart start to vibrate rapidly and chaotically and the heart contracts unevenly and uncontrollably. 

This is called ventricular fibrillation or ventricular fibrillation.

 As a result, the blood is no longer pumped around properly and the circulation stops. This is a life-threatening situation.

  • Cause of sudden death:

The most common cause of cardiac arrest is a myocardial infarction. 

In cases of sudden cardiac death, for example in young people, other causes should also be considered.

 Often the cause of a cardiac arrest in someone under 45 years of age is hereditary heart disease.

Examples of hereditary heart diseases are:

An inherited cardiac arrhythmia. 
An inherited heart muscle disease.

This often concerns young people who have never before had heart problems.

  • Genetic testing:

Especially the sudden death of young people under 45 years of age should be a signal for family members.

If it turns out that the cause was hereditary heart disease, close relatives (children, brothers, sisters, and parents) are also at risk of contracting the same heart disease.

A genetic examination of family members can then reveal whether a person has a hereditary disease. 

This examination takes place at the cardiogenesis outpatient clinic. It requires a referral from your doctor or specialist.

[3] Heart failure treatment:

When you have heart failure you will usually be given medicines and advice on a healthy lifestyle.

This will reduce the workload on your heart and reduce your symptoms.

Sometimes, the cause can be removed or special treatment can be provided.

  • Treatment in hospital:

When the ambulance arrives, paramedics take over resuscitation from bystanders. The patient is taken to the hospital as soon as possible.

After blood circulation is restored, treatment is continued. The body is cooled in the Intensive Care Unit (ICU).

This is done to prevent permanent damage to the heart, brain, and other organs.

First, the doctors slowly lower the body temperature to between 32 and 36 degrees Celsius. 

The body is kept at this low temperature for the first 24 hours. After 24 hours, the temperature is slowly raised. 

The temperature is brought back down to the normal body temperature. This is approximately 37 degrees Celsius.

In the days that follow, the patient will receive various checks. One of these is to assess whether all reflexes are working properly.

  • Healthy lifestyle:

By living a healthy life, you increase the chance of success of the treatment.
Do not smoke, exercise sufficiently, eat healthily and learn how to deal with tension.

Watch fluids and salt:

With heart failure, you will be given advice on how much fluid and salt you should take each day.

You should stick to this. If you are retaining fluid, your heart will have to work harder. This is something you want to avoid with heart failure. 

  • Other treatments:

Sometimes there are other treatments available. Surgery may be able to remove the cause of your heart failure and make you feel better.

For example, you may be given a special pacemaker or ICD to help your heart work better. I

n rare cases, a support heart or heart transplant may be needed.

Special ICD or pacemaker for heart failure

In some people with heart failure, the ventricles no longer contract simultaneously. 

A special pacemaker or ICD ensures that both ventricles contract at the same time again. This treatment is called cardiac resynchronization therapy (CRT).


Hereditary cardiac dysrhythmia is not always recognized in time. Research has enabled us to track down more and more hereditary heart defects.

In this way, people with a predisposition can be treated better, and earlier and sudden cardiac death can be prevented.
