May support low-dose dobutamine echo for predicting LVEF recovery in dilated cardiomyopathy; hypothesis-generating and needs prospective validation.
Does low dose dobutamine stress echocardiography predict the improvement of left ventricular systolic function in patients with dilated cardiomyopathy?
Low dose dobutamine stress echocardiography can identify contractile reserve and predict long-term improvement in left ventricular systolic function in patients with dilated cardiomyopathy.
Kitaoka et al. (1999) studied this question.
