【摘要】：正目的應(yīng)用三維斑點追蹤成像(3D-STI)技術(shù)評價肺動脈高壓(PAH)患者的右心室整體峰值應(yīng)變,并探討右室整體峰值應(yīng)變與肺動脈收縮壓(PASP)、三尖瓣環(huán)收縮期峰值速度(TVSPV)之間的關(guān)系。方法選取PAH患者37例,以及健康對照者32例。應(yīng)用3D-STI技術(shù)測量并比較兩組右室整體收縮期縱向峰值應(yīng)變(GLS)、右室整體圓周收縮期峰值應(yīng)
[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),.
