Focused ultrasound exam accurately identifies at-risk athletes

A young athlete in seemingly excellent health dies suddenly from a previously undetected cardiovascular condition such as hypertrophic cardiomyopathy in nearly every U.S. state annually. Although these conditions can be detected using electrocardiography (ECG) during a screening exam, the American Heart Association recommends against routine use of ECG, because it has a high false-positive rate. Limiting screening to a history and physical, however, usually fails to identify at-risk athletes. "The sports medicine physical lacks an effective way of ferreting out these heart problems," says Gianmichel Corrado, MD, from Boston Children's Hospital Division of Sports Medicine. Until now.

Adding a simple, inexpensive ultrasound exam to the sports medicine physical could help identify athletes with these conditions.

Corrado and colleagues devised the Early Screening for Cardiovascular Abnormalities With Preparticipation Echocardiography (ESCAPE) protocol, which adds a two-minute focused ultrasound exam to the sports medicine physical. They designed a study which showed the protocol reduces the false-positive rate and demonstrated that the exam may detect cardiovascular conditions responsible for sudden cardiac death in this population. The original research was published January 22 in the Journal of Ultrasound in Medicine.

The researchers enrolled 65 male collegiate athletes, aged 18-25 years, in their study. Sports medicine physicians screened participants with a history and physical exam, ECG and focused echocardiography. ECGs were positive in three athletes, but the focused ultrasound exams were normal. Another three athletes screened positive during the history and physical but were cleared both by ECG and focused ultrasound.
