Abstract:
Objective To explore value of quantitative tissue velocity imaging(QTVI) in the regional systolic and diastolic myocardial function of hypertrophic cardiomyopathy(HCM) patients and healthy persons. Methods By Doppler myocardial imaging 20 HCM patients and 18 healthy subjects were collected,then the regional velocity were measured in the mid and basal segment in systolic,early diastolic and later diastolic period respectively. Results The parameters as systolic velocity(Vs),early diastolic velocity(Ve) and early systolic velocity/later diastolic velocity (Ve/Va) of the HCM group were significantly lower than those of the normal group,while later diastolic velocity(Va) showed no statistic difference between two groups. Conclusions The systolic and diastolic myocardial functions of hypertrophic cardiomyopathy patients are reduced. The abnormality of heart function in HCM patients could be accurately detected by QTVI.
