What's Behind Sudden Cardiac Death in Athletes?
Published: May 22, 2024
Sudden cardiac death (SCD) in athletes is a rare yet devastating event, often occurring without warning. Understanding its causes is crucial to help identify at-risk individuals and prevent these tragedies.

Understanding Sudden Cardiac Death
Sudden cardiac death (SCD) is a sudden, unexpected death caused by a loss of heart function. In athletes, SCD is primarily triggered by malignant arrhythmias such as ventricular tachycardia and ventricular fibrillation. These conditions can arise from structural heart diseases or inherited arrhythmic disorders, making it crucial to identify these risk factors early.
Common Causes in Young Athletes
In athletes under 35, SCD is often linked to undiagnosed structural heart diseases like hypertrophic cardiomyopathy or congenital coronary artery abnormalities. These conditions can disrupt normal heart rhythms, leading to fatal outcomes during intense physical activities. Identifying these conditions early through screening can help mitigate the risks.
SCD in Older Athletes
For athletes over 35, coronary artery disease becomes a leading cause of SCD. This age group may experience SCD due to complications from existing heart conditions, often exacerbated by intense exercise. Regular health check-ups and heart evaluations can help manage risks and ensure safe participation in sports.
