ABSTRACT
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.
