Are there any risk factors or red flags?

Risk Factors

The risk factors of sudden cardiac arrest are essentially the same as those of CAD. This reflects the close relationship between the two.

There are often no identifiable red flags, as sudden cardiac arrest (SCA) occurs unexpectedly and suddenly.

However, sudden cardiac arrest is a result of an arrhythmia. There are chances that initially the arrhythmia may not be serious enough to cause a complete cessation of blood flow from the heart but only a reduction of it. This can occur if the heart beat is either too fast or too slow.
