Abstract:
Objective To assess right ventricular systolic function using real-time three-dimensional right ventricular quantitative analysis (RT-3DRVQ) in patients with coronary artery disease (CAD) complicating left heart failure. Methods Sixty-eight patients diagnosed with CAD and left heart failure were selected as the case group.Among them,38 individuals were associated with pulmonary hypertension (PH) and 30 were without. Another 30 healthy people were recruited as control group. Conventional echocardiographic parameters,as well free wall and septum longitudinal strains of right ventricle were evaluated in all subjects. Results Patients with left heart failure had significant lower strain values than control group( P <0.001).In case group,three-dimensional derived right ventricular free wall longitudinal strain (3D-FWLS) had strongly correlation with right ventricular ejection fraction ( r = -0.877, P <0.001). The patients with PH had also significantly reduced 3D-FWLS values compared with patients without PH ( P < 0.01),and the area under the curve was 0.726 using ROC method to predict patients with PH.Conclusions RT-3DRVQ could be recognized as a good technology to evaluate right ventricular systolic function,which would provide valuable information for clinical decision-making.
