Abstract:
ObjectiveTo evaluate regional myocardial systolic function in patients with hypertrophic cardiomyopathy(HCM) by strain and strain rate imaging.Methods38 patients with HCM(observe group) and 36 healthy volunteers(control group) were involved in this study.All subjects were received conventional 2D-Color Doppler echocardiography and Color Doppler myocardial image(CDMI) ,then analyzed the regional myocardial function by strain and strain rate imaging.ResultsComparwed with the control group, left atrial diameters (LAD), left ventricular diameters (LVD), left ventricular end-systolic dimension (LVDs), interventricular ventricular septal (IVS) and left ventricular posterior wall(LVPW) were significantly increased in patients of observe group (all P < 0.05), but left ventricular ejection fraction(LVEF) was decreased(P <0.05).Patients with HCM showed regional longitudinal peak systolic myocardial deformation properties lower than those of counterparts at inferior, lateral, posterior, frontal and septum waLl of left ventricular(all P < 0.05).ConclusionHypertrophic cardiomyopathy was associated with significant reduction in systolic function of left ventricle and strain and strain rote imaging was useful in evaluating the change.
