Assessment of Global Systolic Function of Left Ventriclein Diastolic Heart Failure in Patients with Essential Hypertension Using Speckle Tracking Imaging
摘要
Abstract
Objective To evaluate the value of two￣dimension speckle tracking imaging in assessing left ventricular global systolic function in diastolic heart failure in patients with essential hypertension. Methods The study included 65 patients with essential hypertension and preserved left ventricular systolic function (LVEF >50%),which were divided into patients with diastolic heart failure (n=26,DHF group) and those without heart failure(n=39,NHF group).26 age matched healthy controls were selected randomly.Two￣dimensional echocardiographic images of the left ventricle were acquired in apical four￣,two￣chamber,long￣axis views,and parasternal short￣axis at the basal,mid,and apical levels.Global longitudinal strain (GLS), global radial strain(GRS), global circumferential strain(GCS) were quantified using a novel speckle tracking sys￣tem.Global parameters were investigated among the groups. Results Compared with the control group,the value of GLS, GRS,GCS were significantly reduced in DHF group and NHF group( P<0 05);Compared with the NHF group,the value of GLS,GRS,GCS were significantly reduced in DHF group ( P<0 05) . Conclusions 2D￣STI can evaluate 1eft ventricular global systolic function in diastolic heart failure in patients with essential hypertension,and has potential applications in clini￣cal practice.关键词
