Recent research from Canada shows that over 50% of people who experience sudden cardiac arrest (SCA) during recreational sports survive long enough to leave the hospital. This positive outcome is largely thanks to quick actions from bystanders, including administering CPR and using automated external defibrillators (AEDs).
The study found that CPR was given by bystanders in more than 75% of cases involving athletes. AEDs were used to deliver shocks in about one-third of these incidents. Katherine Allan, who led the research, highlighted how important it is that people respond quickly when they witness a cardiac arrest, especially in places like hockey rinks or gyms.
While SCA can grab headlines, it’s important to remember that these events are rare in sports. The study indicated that men, especially middle-aged athletes, are more likely to experience SCA during sports. “Sport is relatively safe,” stated Dr. Paul Dorian, a senior investigator of the study.
Dr. Matthew Martinez, a member of the American College of Cardiology’s sports and exercise cardiology council, reinforced the study’s findings. He emphasized the critical role of AEDs in saving lives and called for better public knowledge around CPR and AED usage. Making AEDs readily accessible in communities can significantly increase survival rates.
The study, published in the Canadian Journal of Cardiology, looked at data collected from various provinces in Canada between 2016 and 2020. It reviewed over 18,000 cardiac arrests in adults, with 339 occurring during sports or shortly after participation.
Most cases were witnessed, with AEDs used in about 36% of instances and CPR performed in 73.6%. The data revealed the most common sports associated with SCA were hockey, cycling, and running.
Quick involvement from bystanders significantly increases the chances of survival. SCA cases that had immediate CPR or used an AED showed a higher likelihood of surviving to hospital discharge. Whether in public spaces or community centers, visibility and timely responses play major roles in outcomes.
Studies show that survival rates from SCA outside sports are generally low, often less than 10%. By comparison, the survival rate for recreational athletes is much better, bolstered by the prompt response of those nearby, including trained staff.
Dorian stressed the necessity for older athletes to consult their doctors before resuming sports. As many recreational hockey players are middle-aged men, some may have undiagnosed heart conditions. It’s essential for everyone, especially older individuals, to know the location and usage of nearby AEDs.
Martinez reminded athletes that they’re not exempt from heart issues and should take precautions as they age. He encouraged older individuals to practice safe exercise and have plans in case of emergencies.
With survival rates currently above 50% for recreational athletes, Dorian expressed hope for continued improvement, aiming for rates to exceed 60% or even 70% in the future.
