How Sudden Cardiac Death Occurs & it’s Causes?

Sudden Cardiac Death is caused by Sudden Cardiac Arrest (loss of heart’s function). It is estimated that more than 300,000 deaths occur yearly from Sudden Cardiac Death in US. More than half of heart disease is Sudden Cardiac Death. And it’s leading cause of natural death.

Sudden Cardiac Death is Different from Heart Attack:

Sudden Cardiac Death is different from Heart Attack. However, Sudden Cardiac Death may occur in people having a heart attack.

In a Heart Attack, there is blockage and blood flow is prevented to certain area of heart. This results in damage to that area. In Sudden Cardiac Death, the heart loses it’s ability to pump completely resulting in death.

What Causes Sudden Cardiac Death:

Arrhythmia causes Sudden Cardia Death. Arrhythmia is said to have occurred when lower chambers of the heart (ventricles) is unable to pump blood due to disorganized impulses. The heart flutters and becomes unstable. No blood is pumped out and death occurs in minutes.

Risk Factors for Sudden Cardiac Death

Here are some risk factors for Sudden Cardiac Death:

  1. You had previously experienced Sudden Cardiac Arrest
  2. Family history of Sudden Cardiac Deaths
  3. You have suffered a Heart Attack. People who had suffered a Heart Attack have 75% chances of Sudden Cardiac Death.
  4. People with Coronary Artery Disease have 80% chances of Sudden Cardiac Death.
  5. People with heart failure are 9 times more prone to Sudden Cardiac Death compared to common people. Heart Failure is a condition is which heart’s pumping ability is below normal.
  6. Frequent episodes of Arrhythmia.

How to Prevent Sudden Cardiac Death?

Check if you fall under any risk factor. If yes, talk with your cardiologist and get checked immediately.

If you don’t fall under risk factors be on guard for any abnormal rhythms.

What to do if someone is having a Cardiac Arrest?

Quickly give them a CPR. If you are not trained in CPR then just compress the chest until help arrives. The next best is to use AED. Defibrillators can help the heart to beat regularly.
