Cardiac Deaths During Marathons Plummet: Is Your Next Race Safer?

A recent study has unveiled some groundbreaking news regarding the safety of marathon participants in the U.S., revealing that the risk of cardiac death during races has significantly decreased. Conducted by Jonathan Kim, an associate professor at Emory School of Medicine, this investigation follows up on his landmark 2012 study, which was the first to delve into unexpected cardiac arrests during long-distance running events.

Published in JAMA, Kim’s latest findings are nothing short of remarkable. Although the frequency of cardiac arrests among marathon runners has remained stable, the survival rate for those who experience such events has soared, now standing at two times that of previous years. In essence, fewer runners are succumbing to heart attacks during marathons today than ever before.

Media Coverage vs. Reality

Despite the continuing media reports that highlight tragic instances of cardiac arrests during races, Kim emphasizes an essential question: Are these incidents becoming more or less common? “It’s a critical inquiry, especially as recreational running gains popularity in the U.S.,” he states.

A Data-Driven Approach

From 2010 to 2023, over 29 million people completed marathons in the U.S., a staggering increase compared to the preceding decade. Such large-scale data collection posed a challenge, as there is no centralized tracking system for race-related medical events. Instead, Kim’s research team reached out to individual race directors and utilized a comprehensive review of media archives to gather their data.

“We connected with approximately 70% of race directors to obtain vital information on cardiac events, including whether participants survived and their gender,” Kim explained. Additionally, thorough internet searches helped the team compile detailed accounts of both the survivors and the fatalities, revealing a clear pattern in cardiac event occurrences.

The study showed that while the cardiac arrest rate remained consistent—at 0.60 per 100,000 in the latest review, compared to 0.54 per 100,000 in the earlier decade—the death rate from such events had been dramatically halved, dropping from 0.39 to 0.19 per 100,000 participants. This translates to approximately a 50% decrease in mortality rates since 2000-2009.

Moreover, the research confirmed that cardiac arrests are disproportionately more common among male participants compared to females and are prevalent in marathons versus half marathons.

Raising Awareness and Improving Outcomes

What has led to this significant decline in death rates? Kim attributes it to a growing awareness within the running community regarding the risks of cardiac events. “Every single survivor we spoke to had received hands-on cardiopulmonary resuscitation (CPR), and most had immediate access to an automated external defibrillator (AED), which has been pivotal in saving lives,” he noted.

The survival rates of marathon participants mirror improvements seen in other public locations that provide defibrillators, such as airports and casinos, where survival rates from cardiac arrests have similarly improved.

Kim advocates for increased CPR training for race participants and strategic placement of AEDs along racecourses. Furthermore, he underscores the importance of identifying at-risk individuals—often older adults with unidentified cardiovascular issues—before they participate in races. Not only does this improve individual health care, but it also has the potential to significantly reduce the risk of cardiac arrest during events.

Don’t Let Your Next Marathon Become a Risky Gamble!

As participation in marathons continues to grow, understanding and addressing the risks associated with cardiac events has never been more critical. With proactive measures like CPR training, improved emergency response protocols, and enhanced awareness of personal health risks, runners can enjoy their passion for running while significantly improving their safety. Whether you’re an avid runner or a first-timer, these insights could very well make your next marathon not just an exciting challenge, but a much safer one, too!
