Preparticipation athletic screening for genetic heart disease

Area of Science:

• Cardiology
• Sports Medicine
• Preventive Cardiology

Background:

• Sudden cardiac death (SCD) in young athletes, while uncommon, presents a significant public health concern.
• Pre-exercise screening holds potential for preventing SCD by identifying at-risk individuals.
• Existing research has advanced understanding, yet critical knowledge gaps persist regarding optimal screening protocols.

Purpose of the Study:

• To review the incidence and demographics of SCD in young athletes.
• To examine the challenges in differentiating training-induced cardiac adaptations from malignant abnormalities.
• To discuss current screening guidelines, the debate surrounding electrocardiogram use, and the necessity of emergency response plans.

Main Methods:

• Comprehensive literature review of studies on SCD in athletes.
• Analysis of current screening guidelines and diagnostic tools, including the 12-lead electrocardiogram.
• Discussion of the physiological challenges in interpreting cardiac changes in athletes and presentation of a case study.

Main Results:

• SCD in young athletes is a complex issue with ongoing challenges in risk stratification.
• The distinction between physiological cardiac remodeling and pathological conditions remains difficult.
• There is considerable debate regarding the efficacy and implementation of specific screening tools like the electrocardiogram.

Conclusions:

• Effective pre-exercise screening protocols are crucial for preventing SCD in young athletes.
• Further research is needed to refine screening strategies and address diagnostic ambiguities.
• Implementing on-field automated external defibrillators and response plans is vital for immediate management of cardiac events.
