|Coronary Artery Disease Myocardial Perfusion Abnormalities||Drug: Regadenoson; Optison|
Stress perfusion imaging has primarily been done with radionuclide scintigraphy or single photon emission computed tomography (SPECT) and has not reached its full clinical potential because of the poor spatial resolution of SPECT, increased expense of this procedure, patient exposure to ionizing radiation, and lack of availability. The A2A receptor agonist Regadenoson has been utilized to detect myocardial perfusion abnormalities during SPECT myocardial perfusion imaging.
A 100 patient pilot study (Regadenoson Real Time Perfusion Imaging Trial, IRB #566-08-FB) demonstrated the feasibility and accuracy of real-time perfusion echocardiography (RTPE) in detecting coronary artery disease following Regadenoson bolus injection and Definity as an ultrasound contrast agent. The aim of this study is to determine whether similar feasibility and accuracy can be achieved with Optison (a Food and Drug Administration approved ultrasound contrast agent that differs slightly in microbubble size and composition) in detecting coronary artery disease (CAD) following Regadenoson bolus injection. As with the original study, sensitivity, specificity, and accuracy of perfusion and wall motion analysis to identify a coronary stenosis >50% in diameter by quantitative angiography will be analyzed.

Experimental: Regadenoson; Optison
Use of Regadenoson as the chemical stress agent using Optison as a contrast agent during stress echocardiography.
Drug: Regadenoson; Optison
A one-time intravenous bolus of Regadenoson 400 mcg; continuous intravenous infusion of Optison of 2-4 mL/minute.
