Does occurrence during sports affect sudden cardiac arrest survival?

Area of Science:

• Cardiology
• Emergency Medicine
• Public Health

Background:

• Sudden Cardiac Arrest (SCA) occurring during sports activities is associated with higher survival rates, but the reasons are not fully understood.
• This study investigates whether improved initial management, rather than the sports context, explains the better outcomes.

Purpose of the Study:

• To determine if better initial management, specifically bystander cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) use, accounts for the higher survival rates in sports-related Sudden Cardiac Arrest (SCA).

Main Methods:

• A prospective registry of all Sudden Cardiac Arrest (SCA) events in Paris and its suburbs from May 2011 to March 2016 was analyzed.
• Sports-related SCA cases were identified and compared to non-sports-related cases, adjusting for various confounding factors including initial management.

Main Results:

• Out of 13,400 SCA events, 154 were sports-related. Sports-related SCA showed an 8-fold higher survival rate at discharge (39.7% vs. 5.1%).
• Initially, SCA during sports was linked to better survival (OR 1.77). However, after adjusting for bystander CPR and AED use, this association disappeared (OR 1.43).

Conclusions:

• The improved survival rate for sports-related Sudden Cardiac Arrest (SCA) is primarily attributed to more effective initial management, including bystander CPR and AED deployment.
• This underscores the critical importance of public education in basic life support to enhance SCA survival rates across all settings.
