Why the study?
Does the transmitral E to lateral Ea ratio measured by Doppler tissue imaging correlate with symptoms and exercise capacity in patients with hypertrophic cardiomyopathy better than conventional Doppler indices?
Population

Does the transmitral E to lateral Ea ratio measured by Doppler tissue imaging correlate with symptoms and exercise capacity in patients with hypertrophic cardiomyopathy better than conventional Doppler indices?
In patients with hypertrophic cardiomyopathy, the transmitral E to lateral Ea ratio measured by Doppler tissue imaging correlates well with NYHA functional class and exercise capacity, unlike conventional Doppler indices.
