Prognostic value of myocardial perfusion contrast echocardiography in patients with suggested or known ischemic heart disease.

Objective: We sought to determine the prognostic value of myocardial contrast echocardiography (MCE) in patients with known or suggested coronary artery disease compared with technetium-99m sestamibi single photon emission computed tomography (SPECT)-myocardial perfusion imaging (MPI).

Background: The prognostic value of SPECT-MPI is well established for patients with coronary artery disease. It is less well defined by MCE.
