📌 TL;DR: Estudio de videos revela características clínicas y resultados de arresto cardíaco súbito deportivo.
🔬 Puntos clave:
- Súbito arresto cardíaco deportivo (SR-SCA) es la causa principal de muerte en atletas durante el deporte.
- La mayoría ocurre durante actividad moderada a alta.
- El 100% de los videos mostró signos fisiológicos específicos después del colapso.
- AED early use está fuertemente asociado con sobrevivencia.
- Varían las tasas de supervivencia y uso de AED entre regiones.
🎯 Aplicación clínica para LATAM:
La implementación de programas educativos puede mejorar la identificación temprana del SR-SCA, facilitando un resucitado rápido. Es necesario aumentar la concienciación sobre el SR-SCA y expandir el acceso a AEDs en regiones latinoamericanas.
⚠ Limitaciones:

Objective
Sports-related sudden cardiac arrest (SR-SCA) is the leading cause of death in athletes during sports. The objective of this study was to review all available videos worldwide of SR-SCA to better understand presenting features, management and outcomes.
Methods
A total of 48 recorded SR-SCA events were compiled through a multimedia search. Two investigators independently analysed videos to assess demographics, presenting features of SR-SCA, bystander response, management strategies and outcomes. Videos lacking sufficient data for specific variables were excluded from the statistical analysis of that specific variable(s).
Results
Of 48 SR-SCA cases, 47 (98%) occurred in males. Most events (34; 71%) took place during low-to-moderate intensity exertion. Precollapse behaviour included stumbling 13 (27%), swaying 13 (26%), hands on knees 10 (20%) and walking 9 (18%). After collapse, among the videos where the face was visible (n=8), 100% demonstrated open eyes with fixed gaze or eyes rolled back and in cases where the chest was visible (n=31), 100% displayed continued respiratory movements or gasping after collapse. Fellow athletes did not initiate cardiopulmonary resuscitation in any competitive young athlete-victim (0/42). Early automated external defibrillator (AED) use had the strongest association with survival (19/22; 86%). Europe and North America had higher survival (26/36; 68%) and AED use (21/30; 70%) than Africa, South America and Asia (survival 0/12, 0%; AED use 1/6, 17%).
Conclusion
SR-SCA presents with consistent clinical features. Enhancing education on these characteristics can improve timely recognition and prompt resuscitation. Variations in survival and AED use highlight the need to strengthen awareness of SR-SCA and expand global access to AEDs.
