5 Risk factors of sudden cardiac arrest

Sudden cardiac arrest occurs mainly due to a defect in the electrical system of the heart, which leads to sudden collapse of the circulation as well as stopping blood flow to the brain and lungs. Most cases of sudden cardiac arrest die as it's a life-threatening condition and require urgent medical attention.

 Risk factors of sudden cardiac arrest include the following:

  1. Improper management of heart failure: if you have heart failure (manifested mainly with tight chest and shortness of breathing even during rest), certain medications such as ACE inhibitors and beta blockers are recommended to improve the functional capacity of the heart. On the other side, non-commitment to proper therapeutic measures will increase the risk of sudden cardiac arrest.
  2. Cardiac scarring: a scar in the cardiac muscle may affect the electrical system of the heart, which leads to arrhythmia and sudden cardiac arrest. The most common causes of cardiac scarring include... family history, cardiomyopathy, autoimmune disease, viral infections… etc.
  3. Low ejection fraction: having heart failure with low ejection fraction (35% or less) increase the risk of sudden cardiac arrest.
  4. Heavy smoking: smokers are more susceptible for sudden cardiac arrest and heart attack.
  5. Positive family history of sudden cardiac arrest.
