Sudden cardiac death in athletes

Area of Science:

• Sports Cardiology
• Preventive Cardiology
• Exercise Physiology

Background:

• Vigorous physical activity paradoxically increases acute cardiac event risk in athletes.
• Sudden cardiac death (SCD) risk is elevated during exercise, particularly in athletes.
• SCD incidence is low in young athletes but significant in older athletes, with rising participation.

Purpose of the Study:

• To review the incidence and causes of SCD in athletes across different age groups.
• To evaluate cardiovascular screening strategies for SCD prevention in athletes.
• To emphasize the importance of emergency preparedness in sports facilities.

Main Methods:

• Review of existing literature on SCD in athletes.
• Analysis of cardiovascular screening protocols, including ECG and stress testing.
• Discussion of emergency response measures for cardiac events in sports settings.

Main Results:

• Congenital/inherited conditions cause SCD in young athletes; coronary artery disease (CAD) is the primary cause in older athletes.
• ECG-inclusive screening is sensitive but lacks specificity in young athletes.
• Screening for older athletes requires individualized approaches, including stress testing for high-risk CAD patients.

Conclusions:

• Cardiac screening can identify some at-risk athletes, but is not foolproof.
• Tailored screening and robust emergency preparedness are essential for SCD prevention in all athletes.
• Addressing SCD in athletes requires a multi-faceted approach encompassing screening, individualized risk assessment, and readiness for emergencies.
