Left ventricular diastolic function in patients with essential hypertension with speckle tracking and real-time three-plane quantitative tissue velocity imaging
摘要
Abstract
Objective To explore the application value of the left ventricular diastolic function in patients with essential hypertension by speckle tracking imaging( STI ) and real-time three-plane( RT-3PE ) quantitative tissue velocity imaging(QTVI ). Methods Thirty-two patients with essential hypertension and forty healthy subjects were detected for their clinical characteristics. Early diastolic strain rate( Sre ), late diastolic strain rain( Sra )at basal, middle and apical ventricule were measured with STI, then the average of peak strain rate ( mSre, mSra )and mSre/ mSra in the left ventricular were calculated. Early diastolic velocity( Ve )and late diastolic velocity( Va )at six sites of mitral annulus were measured using RT-3PE QTVI to calculate the average peak velocity( mVe,mVa )and mVe/ mVa in the left ventricular. The results were analyzed and compared. Results Compared with control group, the parameters of Ve and Sre in hypertension group were significantly reduced, Va and many parameters of Sra were higher. The average of peak strain rate in early diastolic ( mSre ) and mSre/mSra were significantly lower, while the average of peak strain rate in late diastolic ( mSra ) higher. The average of peak velocity in early diastolic ( mVe ) and mVe/mVa were lower, while the average of peak velocity in late diastolic( mVa ) were higher. Conclusion RT-3PE QTVI and STI can quantify diastolic velocity and diastolic strain rate on walls of left ventricular in patients with essential hypertension properly. It is a new noninvasive method in assessment of left ventricular diastolic function in essential hypertension.关键词
