Do dobutamine-induced changes in LV multidimensional deformation predict cardiac mortality in patients with severe chronic HFrEF?
In patients with severe chronic HFrEF, resting radial strain and dobutamine-induced changes in global longitudinal strain are independent predictors of cardiac mortality, improving risk stratification.
Paraskevaidis et al. (2017) studied this question.
