组织多普勒评价健康肥胖女性左右心室功能

目的 探讨组织多普勒成像(TDI)技术评价我国健康肥胖女性左、右心室功能改变.方法 选择健康肥胖成年人140例,其中女性80例,以TDI技术测量其在二、三尖瓣瓣环收缩期、舒张早期和晚期峰值运动速度(Sm、Em和Am)和Em/Am,并计算各指标平均值(MSm、Mem、Mam和Mem/Am).结果 肥胖组和正常对照组在二、三尖瓣瓣环各取样点Sm、Em、Em/Am以及MSm、Mem、Mem/Am减低,Am、Mam升高.肥胖女性体重增加心功能进一步减低.肥胖女性较男性心功能减低更明显.结论 TDI技术显示成年健康肥胖女性左、右心室功能已出现异常改变,为肥胖女性左、右心室局部和整体功能的早期评价提供了理想的检测手段.

Evaluation of left and right ventricular function by tissue Doppler imaging in healthy obese women

Objective To investigate tissue Doppler imaging(TDI) assessing left and right ventricular function in healthy obese women.Methods 140 healthy obese people underwent DTI,among them 80 women.Peak systolic and peak early and late diastolic velocities (Sm,Em,Am) and Em/Am were measured at mitral and tricuspid annular,and mean value of every index (MSm,MEm,MAm and MEm/Am) was calculated.Results Sm,Em,Em/Am and MSm,MEm,MEm/Am at different sites of mitral annular and tricuspid annular were significantly different in obese and healthy women.reduced and Am and MAm increased at every site in obese group as compared with controll group.With body mass increasing,cardiac function of obese women reduced more obviously.Compared with obese men,obese women had lower cardiac function.Conclusions By measuring myocardial tissue velocities using TDI,left and right ventricular function has become abnormal in healthy obese women.TDI provides an ideal method to evaluate left and right ventricular local and general function early in obese women.
