Heart Screenings for Athletes - Are they worth it?

In recent years I've been getting more and more reports of athletic heart screenings. The schools and sports clubs locally are offering for athletes to get a heart work up for a relatively small fee.

Why are they offering this? Because sudden cardiac death in athletes has been in the news a lot over the years, and we all want to minimize the risk that our child has an undiagnosed heart condition that may cause sudden death when exercising. We want to prevent sudden death by identifying those at risk and keeping them from the activities that increase risk. Communities and schools now are more likely to have defibrillators on hand in case of problems, but some children might benefit from an implantable defibrillator. (Side note: if you've not taken a CPR class in the past few years, a lot has changed, including teaching people how to use defibrillators. And you no longer follow "A B C" so it is very different. CPR is recommended for all teens and adults.)

Is the cost of a heart screen worth it?

A new report, Assessment of the 12-Lead ECG as a Screening Test for Detection of Cardiovascular Disease in Healthy General Populations of Young People (12–25 Years of Age): A Scientific Statement From the American Heart Association and the American College of Cardiology, is a review of whether or not electrocardiograms (ECGs) are beneficial for all athletes prior to sport participation and is endorsed by the Pediatric and Congenital Electrophysiology Society and American College of Sports Medicine.

There has been a lot of controversy over the years whether or not routine ECG screening of athletes is a a cost-effective means to find at risk young people. Northeastern Italy has done a comprehensive screening program of competitive athletes and has lowered their sudden cardiac death rate, which is evidence for the ECG screening. Despite this shown benefit, there are many problems with the feasibility of testing a broad range of athletes to evaluate for risk of sudden death (SD). Complex issues from the Statement linked above:

1. the low prevalence of cardiovascular diseases responsible for SD in the young population
2. the low risk of SD among those with these diseases
3. the large sizes of the populations proposed for screening
4. the imperfection of the 12-lead ECG as a diagnostic test in this venue 

It is generally agreed upon that screening to detect cardiovascular abnormalities in otherwise healthy young competitive athletes is justifiable in principle on ethical, legal, and medical grounds. Reliable exclusion of cardiovascular disease by such screening may provide reassurance to athletes and their families.

In short: To do an ECG screening on all athletes is not inheritantly unwarranted nor discouraged, but it isn't recommended either.

Although an ECG is not recommended, it is recommended to do a 14 point questionnaire for all athletes at their pre-participation sports exam. This is available below.

Positive findings on the history (questionnaire) or physical exam may require further testing, but using an ECG as the initial screen for underlying problems in the 12- to 25-year age group hasn’t been found to save lives.

Changes in the heart in growing teenagers can make it difficult to tell if an ECG is abnormal or a variation for age (unless read by a pediatric cardiologist, which is often not possible for these mass screenings).

False negative and positive results can lead to missed diagnoses (normal ECG but real underlying condition) or unneeded testing (abnormal ECG with a normal heart).

Mass ECG screening of athletes would be very expensive.

If your family can bear the cost and wants to do the screening, it should be done. But if the screen is abnormal, do not jump to the conclusion that your athlete will be banned from sports forever. A more complete exam by a pediatric cardiologist will sort that out.

Know that hearts can change over time, so one normal screen does not guarantee there will never be a cardiac event in your child.

If you do not feel that the screening is something you want to pay for or if you feel that it is not necessary for your child who has a negative 14 point screening, you should not be required to do so. The evidence does not support mass required screenings.

If however, your child has identified risks based on the questionnaire, a more thorough testing should be done.

These 14 points are listed in Table 1 of the above linked statement:

Play it Safe!

As the Spring sport season approaches, it is a good time to review the importance of playing safe to prevent injuries.  Parents want their children to grow up to be well rounded academically and physically.  A great way to be physically fit is to participate in sports, but often kids do too much too soon or play with an injury- which can lead to worsening the injury and removal from the game.  Unfortunately by 13 years of age many kids leave sports due to feelings of inadequacy or burnout.  They lose the many benefits of athletics, including physical exercise, mental well being, drug abuse prevention, and more.  Most young kids should not play at an elite level.  Not all will be natural athletes, but all can and should participate in life long sports to varying degrees.  Emphasizing having fun while improving performance can help kids feel less pressure to win and be the star athlete, but even the star should emphasize fun at younger ages!

In general there are two types of injuries: acute and overuse.  Overtraining syndrome is a mental as well as physical issue that can lead to decreased performance and sports burnout. Acute injuries are commonly recognized, and include things such as sprained ankle, wrist fracture, or concussion.  Overuse injuries are less often identified and are more difficult to diagnose.  They occur subtly over time from repetitive trauma to the bones, joints, and tendons.  Examples include little league elbow, gymnast wrist, or stress fractures.

Acute Injuries:  Although not all injuries can be prevented, you can decrease the risk of acute injuries  by adhering to the rules of the sport and the sport-specific safety measures recommended.  If injury is suspected, removal from the sport until injury is healed is important to prevent further injury.

Overuse Injuries:  In the child and adolescent, overuse is the cause of up to half of all pediatric sports injuries.  It is bone, muscle or tendon microtrauma caused by repetitive stress without adequate healing time.  It begins with pain after activity, then pain during activity without affecting performance, followed by pain during activity that affects performance, and finally pain even at rest.  Children are at increased risk because of their growing bones and inability to recognize or describe symptoms.



Overtraining Syndrome (“burnout”) is the psychologic, physiologic and hormonal changes that lead to decreased performance.  Symptoms include chronic muscle or joint pain, personality changes, increased heart rate at rest, decreased sports performance, fatigue, lack of enthusiasm, and inability to complete usual routines.  Prevention includes encouraging a variety of sports throughout the year, making workouts interesting and fun and having athletes take 1-2 days off per week, plus 2-3 months off per year for other activities.  Overtraining can lead to burnout in the early years, which can cause a child to end participation in sports altogether, which may cause inactivity and contribute to the obesity epidemic in our country.

In general, injury prevention begins with making sure your child is playing in a safe environment with a knowledgeable coach and well fitted safety gear.  My favorite tips:

• Remember that many coaches are volunteers with little (or no) specific training.  Don't assume the coach knows how to prevent or treat injuries... you should ask what their experience is!  Be sure there are always at least 2 adults around (this is abuse prevention... another topic entirely, but important!) 
• Encourage athletes to take the time to warm up and cool down.  
• Make sure athletes drink plenty of water, especially in warm weather. 
• Be sure they are playing at a level that meets their skills. 
• Let them know that they should enjoy playing for the fun of the game, not to win.  
• Be sure to remind them that you enjoy watching them play ~ not watching them win!  
• Have kids take time off a favorite sport to try something different for a season.  This not only keeps the game fun, but it works different muscle groups and improves overall fitness.  
• I am also a firm believer in sleep for kids of all ages! Sports practices and games can interfere with an appropriate bedtime and adequate sleep, so make sure your child doesn't suffer from sleep deprivation. 

American Academy of Pediatrics Guidelines and Recommendations Include:

• Athletes should take 1-2 days off per week from competitive athletics and competitive practice to allow physical and psychological recovery.
• Athletes should be a member of only one sport per season.
• Athletes should take at least 2-3 months away from a specific sport during the year.  During this time another fun activity can be done to prevent loss of skills or conditioning.
• The focus of participation should be fun, skill acquisition, safety, and sportsmanship.
• Weekly training time, number of repetitions or total distance should not increase by more than 10% per week.
• Watch for possible burnout if the athlete complains of nonspecific muscle or joint problems, fatigue or poor academic performance.  Consider time off at that time to allow physical and psychological recovery.
• Use caution for younger athletes who participate in multiple games during a short time period.
• Children should participate in a sport at a level consistent with their ability and interest.
• Single sport specialization should be avoided before puberty.  Young athletes who participate in different sports at various seasons have less burnout and fewer overuse injuries.
• Parents should be aware of the coach’s knowledge of proper training techniques, equipment and training of a particular age group.  Parents should encourage organizations to mandate coach training in these areas.
• Never allow an injured athlete to participate in activities until completely healed or cleared by a physician.
• Children are more at risk for heat injury.  Proper hydration should be encouraged.  Avoidance of prolonged activity in moderate temperatures or any activity in extreme temperatures should be enforced.  
• Ensure proper nutrition:         

Proper caloric intake is based on body size and growth rate in addition to calories burned.  Monitor for signs that the athlete is trying to lose weight to benefit performance (to the detriment of overall growth).

Balance nutritional elements based on the Food Guide Pyramid.

Adequate iron is needed.  The amount of iron needed in the diet is highest during the growing years and sports may contribute to iron losses.  Athletes need adequate iron to bring oxygen to tissues in the body.

Calcium intake is important for normal bone growth and possibly to help prevent and heal stress fractures.

Stop Sports Injuries

Too Little Sleep in Athletes

I am very concerned on many levels about late nights required for local sport programs from a parent perspective and as a pediatrician.

Many physical and emotional problems have been linked to sleep deprivation.  I see many kids who struggle in school and at home with behavior and learning problems that are directly related to loss of adequate sleep.  Poor sleep is also related to obesity, poor growth, depression, anxiety, poor school performance, and so many other issues.  Sleep is needed for release of growth hormone, which is needed for bone and muscle growth, muscle repair, fat burning, and learning.  Sleep loss leads to poor attention spans, inconsistent performance, decreased aerobic endurance, delayed response times, and increased illness, and will therefore affect their game!  There is increased risk of injury in these tired athletes.

You can argue that one late night a week will not have devastating consequences, but I disagree. We have all heard that consistent bedtimes are important for sound sleep.  Ironically sleep deprivation often leads to insomnia and more sleep problems. You cannot sleep "extra" to bank sleep hours.  Kids will often sleep in on weekends to attempt to catch up on the sleep hours missed during the week, but that means a week of struggles emotionally and physically.  It also gets their sleep routine off balance, which again contributes to poor sleep.

It is recommended to exercise at least 2-3 hours before bedtime because exercise is stimulating, making it difficult to fall asleep after exercise until the body temperature and metabolism return to normal.  Yet I find that many school aged kids have practices and games in the late evening into night hours.

School aged kids up to 12 years of age need 9-11 hrs of sleep per night to function adequately.  Practices and games late in the evening shortchange their night's rest by far too many hours.  Don't forget to consider that the time to settle down after the game is up to 3 hours. The following day they are likely to have problems at school.  An overtired child often has MORE problems getting to sleep, which affects the rest of the week.  These younger kids tend to have a lot of noticeable behavior and learning problems. Many are misdiagnosed with ADHD and treated with medication, when all they really need is better sleep. It is simply not acceptable to set them up for this failure.

As kids enter middle school they often need extra sleep due to puberty.  (Growth hormone is released during sleep.)  Unfortunately, school tends to start earlier and their game/practice times are often later, meaning they might be getting up just a few hours after they are falling to sleep.  Do we really want to affect their growth during these important years? 

No wonder many middle and high schoolers fall to sleep in class and struggle with falling grades, irritability, depression, and more.

Kids shouldn't have a hard time getting up in the morning.  If they are, it's a sign of not enough sleep!

I should also include coaches and parents in this, since we will be required to teach and transport these kids. Adults will fall short of their recommended 7-9 hrs of sleep, which affects mood, weight gain, and attentiveness.  This affects not only health, but also home and office life.  Can you wake up before your alarm?  If not, can you get to bed earlier?  That is a healthier choice than adding an extra cup of coffee or energy drink to your day.

We as parents and coaches want our kids to succeed in all areas of life. We want to give them the tools they need for this, which must include proper sleep.  Practice and game times on school nights must take into consideration the sleep requirements of these kids.  I do not want to be responsible for allowing  my child to be out late on school nights, therefore contributing to increased risk of poor school performance, behavior issues, immune deficiencies, depression, growth and obesity, and all the other known consequences of poor sleep. Once these issues surface it is too late to prevent them and the snowball effect begins!

The question: What can parents do?????
