Abstract:
Objective To evaluate the regional myocardial systolic function in the patients with hypertrophic cardiomyopathy(HCM) by strain imaging technique.Methods Doppler myocardial imaging of 20 HCM patients(HCM group) and 22 healthy subjects(control group) was collected,and their regional peak systolic strain in the mid and basal segment was measured respectively.The data were compared and analyzed between the two groups.Results In the healthy subjects,the strain value showed no difference between regional myocardium.In the interventricular septum,anterior and inferior wall of left ventricle,the strain value of HCM group was significantly lower than that of control group.Conclusions Strain imaging could detect the abnormal regional myocardial function of HCM patients accurately, and provide a new quantitative parameter for evaluating the regional myocardial functions.
