Unveiling the Silent Killer: Sport-Related Sudden Cardiac Death—Causes and Prevention

Sport-Related Sudden Cardiac Death (SCD) is a devastating and unexpected event that occurs when a seemingly healthy athlete collapses and dies during or shortly after physical exertion. It is a leading cause of fatalities in young athletes, claiming the lives of approximately 1 in 100,000 individuals annually.

What Causes Sport-Related SCD?

SCD in athletes is often caused by an underlying heart condition that goes undetected or undiagnosed. These conditions can include:

• Hypertrophic cardiomyopathy (HCM): A condition in which the heart muscle is abnormally thickened, making it harder for the heart to pump blood.
• Arrhythmogenic right ventricular cardiomyopathy (ARVC): A condition that affects the electrical system of the heart, causing it to beat irregularly.
• Coronary artery disease (CAD): A condition in which the arteries that supply blood to the heart become narrowed or blocked.
• Dilated cardiomyopathy (DCM): A condition in which the heart muscle becomes enlarged and weakened, making it less efficient at pumping blood.

These conditions can be inherited or acquired, and they often do not have any noticeable symptoms. In some cases, strenuous exercise can trigger the heart to beat irregularly or cause the heart muscle to fail, leading to SCD.

Risk Factors for Sport-Related SCD

While SCD can occur in any athlete, regardless of age, gender, or sport, there are certain risk factors that can increase the chances of it happening. These risk factors include:

• A family history of SCD or other heart conditions
• A history of fainting or seizures
• Chest pain or shortness of breath during exercise
• A heart murmur or irregular heartbeat
• High blood pressure
• Obesity
• Excessive use of drugs or alcohol

It is important for athletes who have any of these risk factors to be evaluated by a cardiologist before participating in strenuous exercise.

Preventing Sport-Related SCD

The key to preventing Sport-Related SCD is to identify and manage risk factors. This includes:

• Getting regular physical exams and heart screenings
• Avoiding strenuous exercise if you have any risk factors for SCD
• Warming up properly before exercise and cooling down afterwards
• Staying hydrated and eating a healthy diet
• Getting enough sleep
• Avoiding drugs and alcohol

In addition, all athletes should be educated about the signs and symptoms of SCD and how to perform CPR. This knowledge can save lives in the event of an emergency.

Screening Programs for Sport-Related SCD

Screening programs can be used to identify athletes who are at risk for SCD. These programs typically involve a physical exam, a family history review, and an electrocardiogram (ECG). ECGs can detect abnormal heart rhythms that could lead to SCD.

Screening programs are not perfect, but they can help to identify athletes who need further evaluation and management. It is important to note that even athletes who pass a screening program are not completely immune to SCD.

Sport-Related SCD is a rare but devastating event. By understanding the causes and risk factors of SCD, and by taking steps to prevent it, we can help to protect the lives of athletes and ensure that they can continue to participate in the sports they love.
