The relationship between echocardiographic epicardial adipose tissue thickness and non dipper hypertension / 中国医师杂志

ABSTRACT

Objective To investigate the correlation between epicardial fat thickness and non dipper hypertension.Methods A total of 150 subjects was included in the study,of which 50 were in the non dipper hypertension group,the same in the non dipper hypertension group and the healthy control group.History collection and routine laboratory tests,ultrasonic measurement of epicardial fat thickness,and 24 hour ambulatory blood pressure monitoring were carried on all subjects.Epicardial fat thickness between groups was compared to primarily analyze the correlation of epicardial fat thickness and non dipper type hypertension.The optimal screening positive value in epicardial fat thickness of non dipper type primary hypertension was obtained by receiver operating characteristic (ROC) curve and maximum Youden index.Results When non dipper hypertension group and non-dipper hypertension group were compared,epicardial fat thickness was significantly increased [(6.30 ± 0.94) mm vs (5.92 ± 0.75) mm,P ＜ 0.05],as compared dipper hypertension group to healthy group,the epicardial fat thickness was significantly increased [(5.92 ±0.75)mm vs (5.50 ±0.13)mm,P ＜0.05].Epicardial fat thickness and non dipper type primary hypertension were linearly related (r =0.43,P ＜ 0.05),and epicardial fat thickness in diagnosis of non dippers primary hypertension optimal screening positive value was 6.01 mm.Conclusions There is a close relationship of epicardial fat thickness and non dipper hypertension.
