Cardiac arrest

What should people know about cardiac arrest causes?

Cardiac arrest is one of the most deadly and leading causes of death. The heart’s electrical system fails to work properly during a cardiac arrest, leading to abnormal heart rhythm. As a result, the heart stops beating, which can cause the person’s death.

In most cases, cardiac arrest strikes without warning. Despite that, there are a few symptoms associated with the disease. If you notice any symptoms of cardiac arrest, provide immediate medical care like cardiopulmonary resuscitation and take the patient to a hospital for further treatment. Max Healthcare is a leading hospital chain in the country and provides high-quality treatment in heart-related diseases. The hospital chain employs the best doctors and comprises good infrastructure and medical facilities.

There are numerous factors that can contribute to a cardiac arrest. Being aware of the causes of this life-threatening condition will help you take the necessary measures on time and help save someone’s life.

Causes of cardiac arrest

One of the major cardiac arrest causes is when the heart’s electrical system ceases to work. The condition can give rise to irregular heartbeats, which can be extremely dangerous. However, there are many other causes of cardiac arrest.

Coronary artery disease

Coronary artery disease is when the plaque blockages lead to the narrowing of the arteries, impacting the blood flow to the heart. It is necessary to have the coronary artery disease treated by a good doctor at Max Healthcare, or else it will cause heart failure, a common cause of cardiac arrest.

Enlarged heart

An enlarged heart is a condition wherein the heart’s muscular walls expand, get enlarged, or become thick. The result is heart’s abnormal contractions leading to arrhythmias and ultimately cardiac arrest.


Electrical signals coordinate heartbeats. When the electrical signals malfunction, it leads to an irregular heartbeat, also known as Arrhythmia. Ventricular fibrillation, a type of Arrhythmia and one of the most common reasons for a cardiac arrest, is a condition wherein the heart’s ventricle experiences rapid heartbeat. It causes the heart to tremble.


 Heart medications are imperative for keeping the heart in good condition. However, certain medications can cause cardiac arrest. Therefore, it is crucial to talk to your doctor and inform them about any medical problems that you are suffering from.

Congenital heart disease

Certain heart diseases are present since birth. So, people with congenital heart diseases are more prone to cardiac arrest.

Heart attack

Heart attack is also cited as one of the reasons for a cardiac arrest. A serious coronary artery disease can cause a heart attack, leading to ventricular fibrillation. Ultimately both heart attack and ventricular fibrillation can cause cardiac arrest.

If you suffer from a heart condition, you must get yourself regularly checked at Max Healthcare so that complications can be detected early and a cardiac arrest prevented.

Risk factors associated with cardiac arrest

Numerous factors can increase the risk of cardiac arrest. Some of these factors are mentioned below.

  • Smoking causes immense damage to the heart, lungs and the person’s overall health. Excessive smoking can also cause cardiac arrest. That is why it is necessary to quit smoking. If you are finding it difficult to kick this habit, talk to your doctor or seek the help of a support group.
  • Obese people are more at risk of cardiac arrest. However, you can effectively manage your weight through proper diet and exercise. Seek advice from your doctor about the ways to control your weight.
  • If you have diabetes, you need to be cautious as this condition can cause cardiac arrest.
  • You are at risk if you have a family history of coronary artery disease. Get your heart regularly screened at a hospital.
  • High blood pressure and high cholesterol can harm the heart and cause cardiac arrest.
  • Many cardiac arrest cases are also the result of a sedentary lifestyle. To keep your heart in good condition, exercise regularly and lead an active life.


Besides knowing the causes and risk factors of cardiac arrest, it would be helpful if you were also aware of the symptoms. Being aware will help you recognisewhensomeone is having a cardiac arrest and immediate medical attention is required. But you need to note that cardiac arrest does not always exhibit symptoms. It can occur without prior warning.

  • Some symptoms to watch out for include:
  • Loss of consciousness
  • Chest pain
  • Shortness of breath
  • Fatigue
  • Nausea and dizziness
  • Heart palpitations
