Differentiating the athlete's heart from hypertrophic cardiomyopathy
Key result
Advanced imaging techniques distinguish athlete's heart from HCM in gray-zone hypertrophy.
Why the study?
Do advanced imaging techniques help differentiate athlete's heart from hypertrophic cardiomyopathy in cases of 'gray-zone' hypertrophy?
Population
Athletes with 'gray-zone' left ventricular hypertrophy and patients with hypertrophic cardiomyopathy

Implication
May enhance differentiation of athlete's heart from HCM on imaging; leaves open prospective validation of criteria before routine use.
Structured PICO
Do advanced imaging techniques help differentiate athlete's heart from hypertrophic cardiomyopathy in cases of 'gray-zone' hypertrophy?
P
Population
Athletes with 'gray-zone' left ventricular hypertrophy and patients with hypertrophic cardiomyopathy
E
Exposure
Advanced imaging techniques including tissue Doppler imaging, speckle tracking echocardiography, and cardiac magnetic resonance imaging
O
Outcome
Differentiation between exercise-induced cardiac remodeling (athlete's heart) and hypertrophic cardiomyopathysurrogate
Advanced echocardiographic techniques and cardiac MRI are useful tools for differentiating physiological athlete's heart from hypertrophic cardiomyopathy in patients with 'gray-zone' hypertrophy.
Limitations
- Studies of the expected degree and time course of LVH regression after exercise cessation are needed
Cite This Study
Wasfy et al. (2015) conducted a review in Athlete's heart and hypertrophic cardiomyopathy. Advanced imaging techniques (echocardiography and cardiac MRI) was evaluated. Advanced imaging techniques, including tissue Doppler, speckle tracking, and cardiac MRI, help distinguish athlete's heart from hypertrophic cardiomyopathy in gray-zone hypertrophy cases.
