Sudden Cardiac Arrest

Sudden Cardiac Arrests
Sudden Cardiac Arrest (SCA) and Sudden Cardiac Death (SDA) refer to the sudden cessation of cardiac activity with hemodynamic collapse.

If an intervention (eg: defibrillation) restores circulation, the event is referred to as SCA. If uncorrected, an SCA event leads to death and is then referred to as SCD.

Epidemiology of SCD
  • Accounts for 10-15% of natural deaths and 60% deaths from cardiac causes
  • Bimodal age distribution with peaks between birth and 6 months of age & after 65 years of age
  • Male preponderance
  • May be the first presentation of cardiovascular disease in 25% of patients
  • General patterns of heightened risk during the morning hours, on Mondays and during the winter months have been described
  • SCA is not random event. Most victims do have heart disease or other heath problems, often without being aware of it.
  • As many as 75% of people who die of SCA show signs of a previous heart attack. 80% percent have signs of coronary artery disease.
  • Approximately 92% of those who experience SCA do not survive.
  • SCA kills more than 1,000 people a day, or one person every second.

Epidemiology of SCD
    • Survivor of sudden cardiac arrest
    • Patients with low heart pumping function (less than 35%)
    • Post heart attack patients
    • Patients with documented ventricular tachycardia
    • History of sudden death or heart disease in family
