Sudden Cardiac Arrest (SCA) - Who's At Risk?
Sudden Cardiac Arrest (SCA) occurs abruptly and without warning, and two-thirds of SCA deaths occur without any prior indications of heart disease. In fact, SCA can happen to people of all ages and health conditions. While signs and symptoms are often not present, there are certain risk conditions for SCA, which include:
- A previous heart attack: individuals who have had a heart attack are at greater risk of SCA — 75 percent of people who die of SCA show signs of a previous heart attack
- A family history of sudden death, heart failure, or massive heart attack
- An abnormal heart rate or rhythm of unknown cause
- An unusually rapid heart rate that comes and goes, even when the person is at rest
- Episodes of Fainting of unknown cause
- A low ejection fraction (EF): The ejection fraction is a measurement of how much blood is pumped by the ventricles with each heart beat. A healthy heart pumps 55 percent or more of its blood with each beat; less than 35 percent indicates an elevated risk of SCA
The SCA Risk Assessment is an interactive tool designed to help individuals estimate their risk of sudden cardiac arrest (SCA), a common cardiac arrhythmia that can occur abruptly and without warning. In fact, two-thirds of SCA deaths occur without any prior indications of heart disease. SCA can happen to people of all ages and health conditions.
