Sudden Death in a healthy person
Much more likely than a heart attack, your friend died because of an arrhythmia called ventricular fibrillation (VF), causing sudden cardiac death (SCD).
SCD can occur in active, outwardly healthy people with no known heart disease or other health problems. While its causes include coronary artery disease (CAD), arrhythmias can occur for other reasons, such as:
- Electrolyte imbalances in your blood (such as sodium or potassium).
- Changes in your heart muscle.
- Injury from a heart attack.
- Healing process after heart surgery.
- Irregular heart rhythms can also occur in "normal, healthy" hearts.
In somebody with a heart healthy life style w/o cardiac risk factors, CAD is unlikely but can be excluded with a variety of tests.
You can test your personal risk for heart disease, and if still concerned about arrhythmias, discuss specific testing with your doctor.
Hope this helps,
