Useful Information for Event Directors

June 26, 2012 By Larry Creswell, MD 1 Comment

Last week’s USA Triathlon Event Services Newsletter included a section devoted to the importance of event insurance.  They recommended 2 recent articles in the March/April issue of Sports Destination Management that dealt with the importance of medical support at your event and with the importance of having sufficient and reliable insurance coverage.

Both of these articles are good reading if you’re involved with race production or direction.

Cardiac Arrest During Long-Distance Running Races: A New Report

January 17, 2012 By Larry Creswell, MD 3 Comments

This past week, the results from an important study on the heart risks of long-distance running was reported in the New England Journal of Medicine.
A group of investigators from Boston looked at the experience of ~11 million runners who took part in half marathon or full marathon races in the United States between 2000 and 2010. This is the largest study of its kind ever undertaken.
The important findings were:
-59 athletes had cardiac arrest and 42 of those died
-For marathon runners the risk of cardiac arrest was 1.01 per 100,000 participants
-For half marathon runners the risk of cardiac arrest was 0.27 per 100,000 participants
-The risk for men was several-fold greater than for women
-The majority of deaths occurred during the last 6 miles of the marathon or the last 3 miles of the half marathon
-From medical records, the cause of cardiac arrest could be determined for 31 victims (23 of whom died). In most of the cases where the athlete died, there was a specific heart condition that was responsible:
—Hypertrophic cardiomyopathy (HOCM) in 8
—Possible HOCM in 7
—Hyperthermia in 1
—Arrhythmogenic right ventricular cardiomyopathy in 1
—Hyponatremia in 2
—No specific cause in 4
Some important, NEW observations were:
–The frequency of cardiac arrest is extremely low….and even lower than previously thought.
–The survival rate from cardiac arrest was surprisingly good, at 29%. This is much higher than previous reports for out-of-hospital cardiac arrest. It suggests that bystander CPR and early defibrillation may be readily available at race venues.
–The risk is greater in marathons, compared to half marathons. The reason(s) are not yet clear.
This new report provides the most comprehensive information yet on cardiac arrest during running races. Athletes should be encouraged by the extremely low rate of cardiac arrest and with the favorable survival rates reported. Athletes should also take note that the cause of cardiac arrest was most often due to an underlying cardiac condition that might be discoverable BEFORE participating in a traning program or race. It’s reasonable to conclude that a pre-participation visit to the doctor for a careful physical examination and, potentially, cardiac testing might reduce an athlete’s chances of being a victim.

Race Safety and USA Triathlon

January 17, 2012 By Larry Creswell, MD 4 Comments

 

I had the chance to attend the annual USA Triathlon Race Director’s Symposium this weekend in Colorado Springs.

Along with Stuart Weiss, MD (medical director of the ING NY Marathon. NY City Triathlon, and upcoming Ironman New York triathlon), Richard Miller, MD (a trauma surgeon at Vanderbilt University), Bob Burnett (a New England race director), and Robert Vigorito (a mid-Atlantic race director), I’m serving on a Medical Review Panel convened by USAT to review the experience with race-related fatalities over the past decade and to offer recommendations about improving race safety going forward.

We’ve had a chance to review preliminary information about race-related fatalities from 2003-2011 and I was asked to present some information to about 80 race directors from across the country who were attending the Symposium.


Some Preliminary Information about Triathlon Fatalities

A snapshot of event-related fatalities at USAT-sanctioned events:
-44 athlete fatalities, including 5 traumatic deaths and 39 non-traumatic deaths
-All 5 traumatic deaths occured with bicycle crashes
-Most (and, conceivably all) of the non-traumatic deaths were due to sudden cardiac death (SCD)
-The majority of the non-traumatic deaths occurred in the swim leg of a race, but there were also deaths in the bicycle and running legs….and 2 deaths that occurred after athletes had completed a race and left the race venue
-Deaths occurred in athletes in nearly every age group
-Deaths occurred in races of every distance from short sprint to Ironman distance

Some Information about Sudden Cardiac Death (SCD)

I shared some general information about SCD, describing reports from 2011 on NCAA athletes and on the French general population:

-In NCAA athletes, the incidence of SCD is 1 per 43,770 athletes per year
-Basketball and swimming appear to have the highest risk

-In the French general population, the risk of SCD is 4.6 cases per 1,000,000 population per year
-Deaths were noted in nearly every conceivable sporting activity
-Deaths were noted in individuals from 11 years old to 70+ years old
-Extrapolated to the U.S. population, there should be 4000+ fatalities in the U.S. due to SCD each year

Feedback from the Attendees

I had a chance to hear from the race director attendees about many relevant experiences. Indeed, several of the race directors who were present had firsthand knowledge about some of the fatalities.

Race directors from Utah were able to share with the audience their approach to dealing with the aftermath of such a fatality–from sharing information at the race venue, to working with family members of the victim, to working with the medical and EMS crews who attended to the victim.

There were many suggestions about how we might work to reduce the number of fatalities:

-Easier access to AED’s, including deploying an AED on a boat so that CPR and defibrillation might occur earlier in the event of a swim leg event
-Reducing anxiety among swimmers before the race. Attendees noted that the NYC Triathlon already employs psychologists to conduct pre-race briefings where coping strategies are discussed
-Wearing inflatable devices during a swim which could be deployed if/when a swimmer experienced difficulties
-Designing swim courses to limit the distance from shore
-Having pre-established action plans for the specific possibility of SCD during the swim

One particularly heart-warming story came from a young race director who shared his personal story of having SCD at the swimming pool in 2010, receiving 14 minutes of CPR, and being resuscitated successfully. He now has an internal defibrillator and is working through the issues of how active he can continue to be. He’s continuing his passion for triathlon by serving now as a race director.

A Visit to USAT’s Offices

On the last evening of the Symposium, we visited the offices of USAT for supper and some fellowship. I was totally fascinated by the many photographs and memorabilia on the walls of the office. The highlights were photographs of the Olympic triathlon teams from the 2000, 2004, and 2008 Olympic Games. Really inspiring.


Ahead

Our Review Panel’s work will continue in the coming weeks as we work to understand more about the athletes who died and about the circumstances surrounding their deaths. I’m optimistic that when we’re finished with our review, we’ll be able to offer some useful advice to USAT and some information to the endurance sport community at large. I’ll keep you posted.

I’d be happy to receive comments and suggestions from the readers here about how we might improve race safety.

Recent Triathlon Deaths

August 29, 2011 By Larry Creswell, MD 6 Comments

In news reports yesterday, I read about the sad news of a triathlete who died during the swim portion of the Ironman Louisville triathlon over the weekend. This death comes just a month or so after the highly publicized deaths of 2 triathletes during the New York City Triathlon. It’s been a while since I’ve written about the issue of sudden cardiac death during triathlons, so I thought I’d share some thoughts.

There has still been little reporting about the tragic event at the Louisville race, but I’ve learned that a 46 year old man was pulled from the water a little more than 300 yards from the start of the triathlon and brought back to the start area to receive further care. Authorities said that he had suffered cardiac death (SCD), was taken to the Louisville’s University Hospital, and was pronounced dead there. I’ve read that an autopsy was performed, but the findings have not been released.

At last month’s New York City Triathon, 2 athletes suffered SCD. One athlete, a 64 year old man died on the day of the event and a 40 year old woman was apparently resuscitated but died a short time later. These deaths attracted a lot of attention in the popular press and I had the opportunity to share some of my thoughts in an article entitled “Why is the Swim the Most Deadly Leg of the Triathlon?” that appeared in the Wall Street Journal. The swim portion of that triathlon was particularly rough and many athletes had to be rescued. Some observers raised questions about conducting the race in those conditions and about the quantity and availability of on-water support to rescue swimmers who weren’t capable enough to complete the swim. I must say, though, that the event organizers are very experienced with directing large triathlons and there appeared to be a robust water safety plan….at least from afar. I was also contacted by The Weather Channel which wanted information and an opinion about how the weather–including water temperature and current–might have played a role in the athletes’ deaths. Again, I suspect this wasn’t a big a factor.

The unfortunate truth is that a small number of athletes will suffer SCD during training or competition….and this is true regardless of the sport. I’ve written previously in a column at Endurance Corner about a recent study by Dr. Kevin Harris of fatalities during triathlon events. In a study of all of the USA Triathlon (USAT) sanctioned events during a 3-year period in the United States, he identified 14 triathletes who died. I recently read in a notice from USAT that nearly 2.3 million individuals completed a triathlon in 2010 in the United States, so you can see how rare an event a race-related fatality really is. Interestingly and importantly, in almost all triathlon fatalities, the victim died during the swim portion of the event and the cause was almost always cardiac-related.

I’ve read through the many discussion threads on this issue at Slowtwitch and other forums and there are obviously many opinions….and many unanswered questions. I think that most of us in the triathlon community could agree that it would be great to prevent some or all of these fatalities, if it were possible. But how?

As I see it, there are only a couple possible ways:

1. Identify victimis of SCD more quickly and provide better and faster medical care so that there might be more survivors.

and/or

2. Ensure that, before participating, athletes learn about any heart conditions they might have….and receive necessary treatment and counseling about participating.

 

USAT Task Force

The week before last I received an email from Rob Urbach, the CEO of USA Triathlon. In that email to USAT Race Directors, he paid special attention to the recent deaths during the New York City Triathlon and indicated that USAT would be convening a taskforce to look at the issue of fatalities during triathlon events. This is a tremendously worthwhile pursuit. I hope that USAT can assemble a group of experts representing the triathlon, medical, and other relevant communities and make a careful assessment of the information that is available about these events. I think this group should:

1. Review the fatalities to look not only for causes of death but also pre-existing medical conditions that might predispose the athlete to sudden cardiac death.

2. Make a careful review of the experience in other endurance (or other) sports (both in and out-of-competition), to place the triathlon statistics into proper perspective.

3. Evaluate the race-day safety resources that are in place to deal with athletes who might suffer sudden cardiac arrest. It is extraordinarily difficult to tend to the victim of SCD in/on the water and we know that CPR and early defibrillation (with just a few minutes) is needed for victims to survive. I’m not aware of any athlete survivors of in-water SCD at a triathlon.

4. Consider what warnings should be issued to participants in terms of the risk of competing and what role that organizers should play (if any) in ensuring the physical ability and medical health of the participants.

As we await the work of the task force, I’d make the following suggestions:

1. For race directors and event organizers. Carefully and critically evaluate your safety plan as it relates to victims of SCD, particularly during the swim. Consider the communication system(s) that are available to water safety personnel and the plans for early CPR and defibrillation should they be needed.

2. For athletes. Realize that there is some small risk of SCD during a race. You should consult with your physician about your particular risk and what, if anything, can be done to reduce that risk. Most athletes would be well served by visiting with a physician for a careful medical history and physical examination that is focused on heart-related problems. Make certain that your overall and heart health are in order before training and competing.

3. For doctors. Become knowledgable about the heart problems that face athletes and be ready to offer sound advice to your athlete patients.

4. For the press. Always give some context for reports on sports-related deaths. Remind your audiences that these events are rare and that exercise provides many proven benefits in spite of any small risk of race-related SCD.

Heart Attack at Tri Camp: A Story for Camp Planners to Remember

March 30, 2011 By Larry Creswell, MD 2 Comments

 

I had the opportunity this past weekend to be Camp Director for a USAT-sanctioned weekend triathlon training camp hosted by our local triathlon club, the Mississippi Heat Triathlon Team. We had a terrific weekend of swim, bike, and run training along with educational sessions in each sport. The campers included more than 60 athletes of all ability levels and our program included a separate track called Triathlon 101 that was designed specifically for beginners. I thought I would share a story from the camp that highlights the importance of safety planning for such events. Our Sunday morning program included breakfast, an hour-long talk about run training, and then a group run. The athletes could choose among 4-, 6-, 8-, or 10-mile groups. We gathered outside in our various groups, each with a coach, had a short briefing about the run, and headed out. Within sight of the neighborhood clubhouse where we started, one of the campers, a 40-year-old man in the Triathlon 101 group, developed severe chest pain. He stopped and the pain gradually subsided over several minutes. Two of his fellow campers, who were both physicians, tended to him and he walked back to the clubhouse where plans were made to drive him to the hospital for evaluation. As it would turn out, he suffered a mild heart attack, underwent cardiac catheterization, was found to have a severe blockage in one of his coronary arteries, and was treated successfully with a coronary stent. He spent 2 nights in the hospital and is now making a good recovery at home. We shouldn’t be surprised that serious heart disease can manifest in the setting of a group of “healthy” athletes. Heart disease is common even in this population. Some take-home messages: 1. Planners of athletic events should be prepared to deal with heart-related medical emergencies. There should ideally be on-site medical professionals as well as easy telephone access to EMS, if needed. 2. It’s important to recognize that transient symptoms of chest pain or shortness of breath can be related to serious heart problems. 3. Even though there are many health benefits of exercise, athletes assume some finite risk of acute heart-related problems every time they exercise or train.
