Cardiac Screening for Young Athletes


February is heart health awareness month. Exercise and sports participation is known to improve heart health. Most young athletes can participate in sports without risk of problems due to heart or cardiovascular health.

Since exercise naturally leads to an increased heart rate and demand on the cardiovascular system, this may cause an athlete with a heart condition to experience sudden and devastating problems during activity. Unfortunately, approximately 1 in 80,000 high school athletes have sudden cardiac arrests (SCA), which may lead to sudden cardiac death (SCD). In most cases, the condition was not known prior to the event.

Adults typically have sudden problems due to coronary artery disease, a condition that develops over years in the vessels that provide blood to the heart. However, young athletes have problems from conditions that were present when they were born or were inherited and have not yet been diagnosed. Here are the most common conditions that affect young athletes:

  • hypertrophic cardiomyopathy

  • anomalous coronary artery

  • arrhythmogenic right ventricular cardiomyopathy

  • idiopathic left ventricular hypertrophy

  • dilated cardiomyopathy

  • long QT syndrome

  • Wolff-Parkinson-White syndrome

  • aortic dissection

  • myocarditis

Properly timed and thorough screening can identify the conditions and prevent these situations. For athletes, screening typically occurs annually during a pre-participation physical or during a well-child visit with the pediatrician. The evaluation depends on the family providing an accurate medical and family history. In regards to heart health, here are some important items to report:

  • shortness of breath or other symptoms with activity

  • history of heart conditions

  • history of blood pressure abnormalities

These are “red flags” on a patient or family history that will lead a health care provider to a more extensive evaluation that may include additional testing:

  • chest pain, tightness, pressure or discomfort during exercise

  • fainting or passing out during or after exercise

  • heart racing or skipping beats with exercise

  • family history of unexpected sudden death at a young age (before the age of 50) from a heart condition or unknown cause

  • history of heart murmur or irregular heartbeat

There are many athletes with various heart conditions that are able to participate in various sports activities. However, each case is unique and each athlete should be treated on an individualized basis in partnership with the athlete’s medical home and a pediatric cardiologist.
