A lot of centers are already using the higher loading dose.

Objective: To evaluate the feasibility of identifying viable myocardium by applying low dose dobutamine echocardiography (LDDSE) combined with Doppler tissue imaging (DTI).

In patients with concentric remodeling and concentric hypertrophy additional first-pass perfusion imaging during high dose dobutamine stress improves the diagnostic accuracy for the detection of CAD.
