摘　　要：目的应用三维斑点追踪成像评价射血分数保留的心力衰竭(HFpEF)患者左心室收缩功能受损程度及发生率,探讨其临床意义。方法选取心力衰竭患者65例,分成HFpEF组35例、射血分数减低的心力衰竭(HFrEF)组30例,同时选择舒张功能减低(LVDD)组30例、正常对照组45例。实时三维超声测量左心室射血分数、左心室质量指数。三维斑点追踪成像测量左心室整体应变(GS)、左心室纵向峰值应变(GLS)、圆周峰值应变(GCS)、径向峰值应变(GRS)。结果与正常对照组相比,HFpEF、HFrEF组患者左室GS、GLS、GCS、GRS呈逐渐减低的变化趋势(P<0.05);HFpEF患者中GLS、GCS、GRS减低的发生率分别为82%、54%、36%。结论 HFpEF患者左心室收缩功能普遍受损,三维斑点追踪成像测定左室收缩功能在HFpEF患者心功能评价中具有重要价值。Objective To determine the severity and frequency of impaired systolic function in HFpEF using 3DSTI and investigate its clinical significance.Methods A total of 65 heart failure patients were selected and divided into HFpEF group（n=35）and HFrEF group（n=30）.LVDD group（n=30）and normal control group（n=45）were collected.The LVEF and LVMi were obtained using three-dimensional ultrasonography and the GS,GLS,GCS and GRS were measured by three-dimension speckle tracking imaging.Results Compared to normal group,there were significant step-down changes from HFpEF to HFrEF in GS,GLS,GCS and GRS.The incidences of GLS,GCS,GRS in HFpEF were 82%,54%,36%.Conclusions The left ventricular systolic dysfunction existed generally in HFpEF.Thus,assessing left ventricular systolic function using 3 D-STI has important clinical value in HFpEF patients.
