Abstract：Objective To measure the epicardial adipose tissue(EAT)thickness by echocardiography in patients with rheumatoid arthritis(RA)and to investigate its relationship with atrial function.Methods Forty-four RA patients(RA-group)and 30 healthy controls(control group)were selected.The systolic EAT(EATs)and diastolic EAT(EATd)thick-ness,atrial systolic peak velocity(PV),and atrial wall electro-mechanical contraction time difference were compared and their correlations were analyzed.Results The thickness of EATs and EATd increased in the RA group(P<0.05).In the RA group,the PV of left atrial lateral, posterior, anterior wall and right atrial lateral wall was lower than that of the control group(P<0.05).Moreover,the electro-mechanical contraction time difference between left atrial lateral and poste-rior wall,anterior and posterior septum wall was higher than that of the control group(P<0.05).In the RA group,EATs was negatively correlated with PV of the left atrial lateral and anterior wall(r=-0.376,-0.461;both P<0.05).Both EATs and EATd were positively correlated with the time difference between left atrial lateral and posterior septum wall,elec-tro-mechanical contraction time difference between the left atrial anterior septum and posterior wall,and waist-hip ratio(r=0.640,0.775,0.393;r=0.625,0.669,0.334;all P<0.05).Conclusions EATs and EATd increase in RA patients, the thicker the EATs,the more severe injury of the patients′atrial function.
