Abstract: Objective To evaluate the right heart functional changes in diabetic patients by echocardiographic technology.Methods A total of 100 cases of diabetic patients were selected,among them,50 patients with diabetic cardiomyopathy(DCM) were divided into the DCM group,50 patients with non-diabetic cardiomyopathy(NDCM) were in the NDCM group;at the same time,50 cases of healthy people were in the non-cardiomyopathy(NC) group.The right ventricular systolic function,diastolic function and right atrial function were measured and compared respectively,and right heart function changes in diabetic patients were evaluated.Right ventricular systolic functions included M mode echocardiography in obtaining tricuspid annular plane systolic excursion(TAPSE),QLAB-MVI in obtaining global longitudinal strain(GLS),right ventricular contrast echocardiography in obtaining right ventricular end systolic volume(RVESV) and right ventricular end diastolic volume(RVEDV) by Simpson,calculating right ventricular ejection fraction(RVEF).Right ventricular diastolic functions included speckle tracking imaging(SDI) in obtaining early diastolic filling velocity(Ve),atrial systolic filling velocity(Va),early diastolic filling strain rate(Esr) and atrial systolic filling strain rate(Asr).Right atrial functions included right atrial contrast echocardiography in obtaining right atrial max volume(Vmax) and min volume(Vmin),calculating right atrial stroke volume(RAV);obtaining volume of right atrium before contraction(Vpre),right atrium passive emptying volume(RAPEV),right atrium passive emptying volume fraction(RAPEV),right atrium active emptying volume(RAAEV),right atrium active emptying volume fraction(RAAEF).Results The level of TAPSE,GLS,RVEF,Ve,Ve/Va and Esr in NDCM and DCM group were lower than those in NC group(P<0.01).With the extension of course,the level in DCM group was lower than that in NDCM group(P<0.05).The level of RVEDV,RVESV and Asr in NDCM group and DCM group were higher than those in the NC group(P<0.01).With the extension of course,the level in DCM group was higher than that in NDCM group(P<0.05).The level of Va in the three groups had no statistically significant difference(P>0.05).The level of Vmax,Vmin,RAV,Vpre and RAAEF in NDCM and DCM groups were higher than those in NC group(P<0.01).With the extentsion of course,the levels in DCM group was increased compared with those in NDCM group(P<0.05).The level of RAPEF in NDCM and DCM groups were lower than those in NC group,while the difference was not statistically significant(P>0.05).Correlation analysis showed that the right artial RAAEF was positively related with right ventricular ASR(r=0.390,P<0.05),the right artial RAPEF was positively related with right ventricular ESR(r=0.508,P<0.05).Conclusion There was exactly right heart function damages in diabetic patients,right heart function change can be early evaluated by combining a variety of methods.
