目的应用应变/应变率技术评价超重及肥胖者左心房功能的变化.方法 30例超重者(28kg/m2 ＞BMI≥24 kg/m2),30例肥胖者(BMI≥28 kg/m2)及30例正常人.应用超声心动图及应变/应变率技术测量左心房5个壁10个节段左房应变(S)、左室收缩期左房应变率峰值(SSR)、左室舒张早期左房应变率峰值(ESR)及左室舒张晚期左房应变率峰值(ASR),并计算出平均值进行比较.结果与正常组相比,超重组平均SSR及平均ESR减低,肥胖组平均S、平均SSR及平均ESR降低,超重组平均ASR降低;肥胖组平均ESR较超重组降低.结论超重者左房储存器、管道及助力泵功能均受损,肥胖者左房储存器及管道功能受损更为明显,而助力泵功能未见明显受损.左房的三个功能相互调节来维持左室充盈.应变及应变率技术可用来评价超重及肥胖者左房功能改变.

Objective To investigate the impact of overweight and obesity on left atrial (LA) function in healthy subjects with excess body weight.Methods Conventional echocardiography and tissue Doppler imaging were performed in 30 obese subjects (BMI≥28 kg/m2),30 overweight subjects (BMI,24to 28 kg/m2) and 30 age-matched normal subjects (BMI＜24kg/m2).Strain (S),peak systolic strain rate (SSR),peak early diastolic strain rate (ESR) and peak late diastolic strain rate (ASR) values were used to evaluating LA function.Results Compared with controls,mean S,SSR and ESR were decreased in obese subjects,while mean SSR,ESR and ASR were decreased in overweight subjects.Compared with overweight subjects,mean ESR was decreased in obese subjects.Conclusions An impaired LA function is found in overweight and obese subjects who has no other clinically appreciable cause of heart disease by using strain and SR imaging.
