Insights
Medical students effectively screened young athletes for hypertrophic cardiomyopathy (HCM) using point-of-care ultrasound. This approach aids in detecting the life-threatening genetic cardiovascular disease early.
Area of Science:
- Cardiology
- Medical Education
- Diagnostic Imaging
Background:
- Hypertrophic cardiomyopathy (HCM) is a dangerous genetic cardiovascular disease.
- It often goes undetected in young athletes, as traditional screening methods are unreliable.
- Early detection is crucial for preventing sudden cardiac events.
Purpose of the Study:
- To evaluate the effectiveness of medical student volunteers in screening young athletes for HCM using ultrasound.
- To determine if point-of-care ultrasound (POCUS) can be a viable screening tool for HCM in this population.
Main Methods:
- A prospective study enrolled 2332 young athletes from high schools and colleges.
- Trained medical students performed POCUS screenings for HCM.
- Screenings were reviewed by a pediatric cardiologist; a septum-to-posterior-wall ratio > 1.25 indicated a positive screen.
Main Results:
- 137 athletes (5.8%) had a positive HCM screen.
- 7 athletes (5.1% of those with positive screens) were confirmed to have HCM.
- The screening demonstrated 100% sensitivity for detecting HCM in the positive cohort.
Conclusions:
- Medical students, with minimal training, can effectively use POCUS to screen young athletes for HCM.
- POCUS represents a promising tool for early detection of HCM in athletic populations.
- This strategy can help identify at-risk individuals for this serious cardiovascular condition.
Objectives:
Hypertrophic cardiomyopathy (HCM) is a life-threatening genetic cardiovascular disease that often goes undetected in young athletes. Neither history nor physical examination are reliable to identify those at risk. The objective of this study is to determine whether minimally trained medical student volunteers can use ultrasound to screen for HCM.
Methods:
This was a prospective enrollment of young athletes performed at 12 area high schools and three area colleges, between May 2012 and August 2013. All participants underwent point-of-care ultrasound performed screening for HCM by trained medical students and reviewed by a pediatric cardiologist. An interventricular septum to left ventricular posterior wall ratio greater than 1.25 was considered to be abnormal (positive screen).
Results:
A total of 2332 participants were enrolled. There were 137 (5.8%) with a positive screening for HCM, of which 7 (5.1%) were confirmed to have HCM by a pediatric cardiologist. In a small cohort with positive screen for HCM, there was a 100% sensitivity (95% confidence interval, 59.04 to 100%) and 4.86% (95% confidence interval, 1.98 to 9.76%) positive predictive value of for having HCM.
Conclusions:
Volunteer medical students, using point-of-care ultrasound, were able to effectively screen for HCM in young athletes.
