Cardiovascular screening of athletes

Area of Science:

• Cardiology
• Sports Medicine
• Preventive Cardiology

Background:

• Sudden cardiac death (SCD) in athletes raises significant concern, as they represent a healthy population.
• Most athletes experiencing SCD are asymptomatic, highlighting the need for effective screening methods.
• Early detection of underlying cardiac conditions can enable therapeutic interventions to mitigate risk.

Purpose of the Study:

• To evaluate the effectiveness of current screening methods for exercise-related sudden cardiac death in athletes.
• To discuss the limitations of existing tools and explore future directions in cardiovascular screening for athletes.
• To emphasize the importance of a multi-faceted approach to risk mitigation beyond screening.

Main Methods:

• Review of current literature on exercise-related sudden cardiac death in athletes.
• Analysis of the utility and limitations of the 12-lead electrocardiogram (ECG) in screening.
• Discussion of emerging technologies and strategies for cardiovascular disease prevention in athletes.

Main Results:

• The 12-lead ECG is effective for detecting electrical abnormalities and suggesting cardiomyopathy but has limitations.
• ECG interpretation guidelines have improved accuracy by accounting for physiological remodeling.
• A significant percentage of conditions causing SCD in young athletes remain undetected by ECG, and its value diminishes in older athletes with coronary artery disease.

Conclusions:

• No single screening test can identify all causes of exercise-related sudden cardiac death.
• A combination of screening, prompt resuscitation, defibrillator availability, and public awareness is essential for risk mitigation.
• Future screening strategies will likely integrate artificial intelligence, wearable technology, and global accessibility.
