Why the study?
HCM and LVH secondary to systemic hypertension may involve LA functional abnormalities, but LA mechanics and their correlation with CMR-measured fibrosis in HCM needed characterization.
Can left atrial mechanics measured by speckle tracking echocardiography discriminate hypertrophic cardiomyopathy from hypertensive left ventricular hypertrophy and predict myocardial fibrosis?
Can left atrial mechanics measured by speckle tracking echocardiography discriminate hypertrophic cardiomyopathy from hypertensive left ventricular hypertrophy and predict myocardial fibrosis?
Left atrial strain rate parameters can effectively discriminate hypertrophic cardiomyopathy from hypertensive hypertrophy and correlate with the degree of myocardial fibrosis.

May support LA strain assessment to differentiate HCM; leaves open prospective validation before clinical adoption.
