Key result
Dobutamine-induced change in left ventricular functional reserve independently predicted 1-year cardiac death, partial left ventriculectomy, or heart failure hospitalization (beta=-0.63, p=0.0035).

Dobutamine stress echocardiography-derived LV contractile reserve is an independent predictor of one-year adverse clinical outcomes in patients with idiopathic dilated cardiomyopathy.
Otašević et al. (2005) conducted a cohort in idiopathic dilated cardiomyopathy (n=48). Right and left ventricular contractile reserve assessed by dobutamine stress echocardiography was evaluated on Combined end-point of cardiac death, partial left ventriculectomy and hospitalization for congestive heart failure (beta=-0.63, p=0.0035). Dobutamine-induced change in left ventricular functional reserve independently predicted 1-year cardiac death, partial left ventriculectomy, or heart failure hospitalization (beta=-0.63, p=0.0035).
