中文摘要:目的:应用实时三维超声心动图(real-time three-dimentional echocardiography, RT-3DE)定量评价冠心病合并2型糖尿病患者的右心功能。方法:门诊及住院患者,分3组:冠心病组(CHD组)16例,糖尿病组(DM组)20例,冠心病合并糖尿病组(CHD+DM组)27例,同时选取24例门诊体检健康者作为正常对照组(NC组)。对入选者应用RT-3DE行三维容积成像,并应用四维右室功能(4D-RVF)分析软件计算右室整体舒张末期容积(RVEDV)、收缩末期容积(RVESV)及射血分数(RVEF),分别进行各组间比较。结果:与NC组比较,CHD组、DM组及CHD+DM组的RVEDV及RVESV明显增大(P<0.05),RVEF无显著差异 (P=0.31)。结论:CHD、DM及CHD+DM患者即使常规超声心动图检查结果为右室内径正常、右室收缩功能无明显变化,但是其容积与正常对照组比较已增大。
英文摘要:Objective: To quantitatively evaluate the right ven tricular function coronary heart disease patients with or without type 2 diabetes mellitus using real-time three-dimensional echocardiography (RT-3DE). Methods: Sixty-three patients were enrolled. They were classified into three groups: coronary heart disease group (CHD group, n=16), type 2 diabetes mellitus group (DM group, n=20), and coronary heart disease with type 2 diabetes mellitus group (CHD + DM group, n=27).The control group (NC group) included 24 healthy volunteers. All the patients underwent tranditional echocardiography and real-time three-dimensional echocardiography (RT-3DE) examination. The overall right ventricular end-diastolic volume (RVEDV), end-systolic volume (RVESV) and ejection fraction (RVEF) were calculated by right ventricular function (4D-RVF) analysis software. Results: Compared with control group, RVEDV, RVESV in CHD group, DM group and CHD + DM group increased significantly(P<0.05) even though RVEF had no statistical differences among 4 groups(P=0.31). Conclusions: The capacity of right ventricle of patients in CHD group, DM group and CHD + DM group enlarged obviously detected by RT-3DE while LVEF were all at normal range.
