Abstract:
Objectives:The aim of this study was to compare the potential differences on echocardiographic cardiac chambers size and systolic function among the healthy Han, Tibetan and Yugur adults. Methods:A total of 1 820 healthy volunteers aged 20 to 80 years were screened at Qinghai province and Gansu province, including 887 Han (456 men), 506 Tibetan (262 men) and 427 Yugur (187 men) Chinese adults. Standard two-dimensional echocardiography was performed to obtain measurements of the cardiac chambers and left ventricular ejection fraction (LVEF). The impacts of nationality, age and gender on all echocardiographic results were analyzed. Results:The values of left ventricular end-diastolic volume was higher in Yugur male adults than in Han and Tibetan male adults ([96.29±21.60]ml vs [93.64±18.30] ml vs [91.16±16.77] ml, P＜0.05).The differences remained after adjusting body surface area ([54.16±11.14]ml/m2 vs [53.92±10.20] ml/m2 vs [52.76±8.94] ml/m2, P＜0.05). There was no significant difference in LVEF among three nationalities (P＞0.05). The values of cardiac chambers dimensions were significantly higher in men than in women (P＜0.05). The anteroposterior dimension of the left atrium increased with age in both genders (P＜0.05). Conclusions:Our results show that the left ventricular end-diastolic volume is related to nationality and some parameters vary with gender and age. Not only the differences in age, gender, body size, but also ethnic differences should be considered when defining the normal values of echocardiographic examination.
