Apical but not basal RV strain reflects right ventricular dysfunction in patients with dilated cardiomyopathy

Abstract Background RV dysfunction is an important predictor of morbidity and mortality in cardiac patients, especially those having dilated cardiomyopathy (DCM). Deformation imaging parameters (strain strain rate) are established as new echocardiographic measures that allow for both global regional function assessment. Previous studies showed heterogeneous segmental deformation affects differently various disease states. Echo-Doppler LV including longitudinal strain, basal & apical ejection fraction were evaluated 42 DCM patients 28 normal subjects, aiming to assess the value versus detection with cardiomyopathy. Results had significantly lower values compared subjects ( p < 0.001). Basal did not differ from normal. The correlated 0.001 all). Using ROC curve, a cut-off ≤ 29.5 distinguished 91.2% sensitivity 100% specificity. Conclusions but reflects status function, it represents valuable measure diagnose DCM.
