Keywords: Cardiomyopathy, Cardiomyopathy, hypertrophic obstructive cardiomyopathy, hypertrophic non-obstructive cardiomyopathyHypertrophic cardiomyopathy (HCM) can be divided into two types according to pressure gradient of left ventricular outflow tract, which means different prognosis and risk stratification. Feature tracking technology can be used to calculate strain value in three orientations and evaluate the ability of myocardial deformation. Our results showed that strain differences can be detected between HCM and control group. Segmental strain and torsion also showed significant differential value between hypertrophic obstructive cardiomyopathy (HOCM) and hypertrophic non-obstructive cardiomyopathy (HNOCM) group.Our study may provide evidence in differentiating HOCM and HNOCM for further treatment.
