Association between basic life support and survival in sports-related sudden cardiac arrest: a meta-analysis.

Aims: To evaluate the association of basic life support with survival after sports-related sudden cardiac arrest (SR-SCA).

Methods And Results: In this systematic review and meta-analysis, a search of several databases from each database inception to 31 July 2021 without language restrictions was conducted. Studies were considered eligible if they evaluated one of three scenarios in patients with SR-SCA: (i) bystander presence, (ii) bystander cardiopulmonary resuscitation (CPR), or (iii) bystander automated external defibrillator (AED) use and provided information on survival.
