【摘要】：正目的应用三维斑点追踪成像(3D-STI)技术评价肺动脉高压(PAH)患者的右心室整体峰值应变,并探讨右室整体峰值应变与肺动脉收缩压(PASP)、三尖瓣环收缩期峰值速度(TVSPV)之间的关系。方法选取PAH患者37例,以及健康对照者32例。应用3D-STI技术测量并比较两组右室整体收缩期纵向峰值应变(GLS)、右室整体圆周收缩期峰值应
[Abstract]:Objective to evaluate the global peak strain of right ventricle in patients with pulmonary hypertension (PAH) by using three-dimensional speckle tracing imaging (3D-STI) and to explore the relationship between global peak strain of right ventricle and peak systolic velocity of (PASP), tricuspid annulus (TVSPV). Methods 37 patients with PAH and 32 healthy controls were selected. 3D-STI technique was used to measure and compare the longitudinal peak strain of the whole systolic period of the right ventricle in two groups. The peak value of the whole circumferential systolic phase of the right ventricle was measured and compared by (GLS),.
