Abstract:ObjectiveTo explore the value of real-time three-dimensional echocardiography (RT3DE) in the assessment of subclinical dysfunction of left ventricle (LV) induced by anthracyclines in patients with diffuse large B-cell lymphoma (DLBCL).Furthermore,to explore the sensitive parameters of RT3DE in the assessment of subclinical dysfunction of LV.MethodsRT3DE images were acquired from twenty-six patients with DLBCL before chemstherapy,after 2(100mg/m2),4(200mg/m2) and 6(300mg/m2) chemotherapy cycles for evaluation and analysis to obtain LV end-diastolic volume (EDV),end-systolic volume (ESV),systolic volume (SV) and ejection fraction (EF).Global longitudinal strain (GLS),global circumferential strain (GCS),left ventricular twist (LVtw) and left ventricular torsion (LVtor) were also calculated.ResultsChanges in EDV[(71.4±14.8)mL,(76.3±15.6)mL,(81.7±19.5)mL,(79.7±16.2)mL]、ESV[(22.9±5.1)mL,(25.1±5.4)mL,(27.1±8.1)mL,(26.6±6.7)mL],SV[(48.6±10.4)mL,(51.2±11.0)mL,(54.6±12.8)mL,(53.1±10.7)mL],EF[(67.9±3.1)%,(66.9±3.1)%,( 67.0±4.1)%,(66.7±3.6)%],GLS[(-26.9±4.8)%,(-27.1±4.4)%,(-25.5±7.5)%,(-26.7±7.1)%],GCS[(-34.7±2.5)%,(-33.7±3.4)%,(-34.1±3.8)%,(-33.7±3.3)%] showed no significant degradation compared with the parameters at baseline as well as,after 2,4 and 6 chemotherapy cycles (F=1.095,2.297,1.388,0.628,0.344,0.585,respectively,all P>0.05),while the variations on LVtw[(19.9±6.8)°,(13.1±10.0)°,(13.5±8.1)°,(11.1±5.8)°],LVtor[(2.9±1.2)°/cm,(1.8±1.4)°/cm,(1.8±1.1)°/cm,(1.5±0.8)°/cm] decreased statistically compared with the data at baseline,and after 2,4 and 6 chemotherapy cycles (F=6.007,7.013,respectively,P<0.05,respectively).Changes on LVtw,LVtor showed statistically reduction after 2,4 and 6 chemotherapy cycles compared with the parameter at baseline (LVtw:P=0.025,0.016,0.001,respectively;LVtor:P=0.008,0.007,0.000,respectively).ConclusionLVtw and LVtor derived from RT3DE may be used as sensitive parameters to detect subclinical left ventricular dysfunction in patients with DLBCL underwent anthracycline therapy.
