2、特征及其与左心结构和功能的关系。.方法对WCH70例及健康的血压正常者30例,应用超声心动图检查评价左心结构和功能,获得超声心动图指标左房容积指数(LAVI)、左室质量指数(LVMI)、二尖瓣口舒张早期与晚期血流峰值流速比值(E/A)、左室射血分数(LVEF),以及脉冲组织多普勒(PW-TDI)指标二尖瓣环心肌收缩峰值速度(Sm)及二尖瓣环心肌舒张早期峰值运动速度(Em)与舒张晚期峰值运动速度(Am)EL值(Em/Am)。30例正常血压者为对照组。比较组间超声心动图各参数的差异,分析血压变异与超声心动图参数之间的相关性。结果1
3、.组间动态血压比较:WCH组白昼平均收缩压、24小时平均收缩压及舒张压显著高于对照组(PO.05)。4.相关分析显示:24tJ,时、白昼及夜间平均收缩压、年龄、性别、体重指数、白昼及24d,时收缩压变异与左室质量指数显著正相关(尸4、、体重指数、白昼收缩压及舒张压变异、24小时收缩压及舒张压变异、E/A、Em/Am、左室质量指数与左房容积硕士学位论文中文摘要指数显著正相关(尸5、XLvⅦ一O.034XB^缸+4.759(P6、X24hsBp+14.203X性,#0.723X括.一19.675(尸7、ressurevariability(BPV)inwhitecoathypertension,inordertoassesstherelationshipbetweenBPVandleftcardiacstructureandfunction.Methods:70subjectswithwhitecoathypertensionand30normalcontrolsunderwentconventionalechocardiographyformeasurementofLeftventricularintemaldimensi8、onofdiastole(LVIDd),Interventricularseptumthickness(IVST),leftventricularposteriorwallthickness(LVPWr),leftventricularmassindex(LVMI),left
