1、Tei指数对高血压不同左室构型左、右心室功能的研究硕士研究生:王洪霞指导教师:高晓军教授专业名称:影像医学与核医学摘要目的:探讨多普勒超声指标Tei指数评价原发性高血压不同左室构型左、右心功能的临床价值,进一步研究左、右心功能的关系。方法:原发性高血压患者96例,按Ganau分类法将原发性高血压分为4型:正常构型(I组,25例)、向心性重构(If组,26例)、向心性肥厚(III组,27例)、离心性肥厚(IV组,】8例);选择30例健康人作为正常对照组。以卜型超声检查测量舒张末期室间隔厚度、左事后壁厚度和左室内径(IVST、LVPWT、LVEDD);
2、取心尖四腔切面二、三尖瓣血流频谱图舒张早期与舒张晚期速度(E峰,A峰)及E/A比值:组织多普勒检查采用二尖瓣前叶、三尖瓣隔叶瓣环运动频谱图,测量收缩期运动幅度S峰,舒张早期速度(Ea),舒张晚期速度(Aa)及速度比(Ea/Aa);左、右室射血分数(EF)以及左、右室Tei指数。结果:与对照组比较,高血压左、右心室舒张功能均减低,I、I【、II【组E/A3、1,0.45±0.18,0.54±0.26,0.674-0.25,0.3±0.06,PrO05),III组与I组,Ⅳ组与I、II、III组间差异有显著性意义(P4、0.38,尸<0.01),而与E/A无相关性(r一0.06/一0.07,DO.05)。左、右心室相对应的一tl,功能参数(7Fej指数、EF、Ea/Aa、E/A)间均有良好正相关性(r分别为0.55,0.77,0.75,0.65,P5、左心功能损害的患者右心功能也受到了损害。Tei指数能简便、敏感、综合评价高血压病患者左、右心室的收缩和舒张功能,是一项评价心功能的多普勒超声新指标。关键词:Tei指数高血压心室功能AssessmentofLeftandRightVentricularFunctioninEssentialHypeaensionwithLeftVentricularDifferentGeometricPattemsbyTelIndexPostgraduate:WangHongxiaTutor:GaoXiaojunSpeciality:MedicalImagingand6、NuclearMedicineAbs拓actobjective:ToexploretheclinicalvalueofTeiindexinassessmentofleftandfightventricularfunctioninpatientswithessentialhypertension,Methods:Ninety-sixpatientswithessentialhypertensionwereenrolled.AccordingtoGanaucategories,thesepatientsweredividedintofourgroups7、aSfollows:normalleftventricle(groupI,25cases),concentricremodeling(groupII,26cases),concentrichypertrophy(groupIII,27cases)andeccentrichypertrophy(groupIV,18cases),and30age—matchedhealthysubjectsascontralgroupwereincluded.Theend-diastolicdiametersofleftventricle(LVEDD),interve8、ntricularseptumthickness(IVST),leftventricularposteriorwallth
