Outcome Measures

Primary Outcomes (1)

  • To demonstrate the non-inferiority of the diagnostic performance of PB127 MCE versus stress SPECT in the detection and/or exclusion of significant obstructive CAD as defined by QCA or qualifying clinical outcome.

    90 days

Secondary Outcomes (2)

  • To assess the concordance of PB127 MCE with stress SPECT in differentiating between reversible vs. fixed defects in patients with significant obstructive CAD

    28 days

  • To compare the diagnostic performance of PB127 MCE with stress SPECT in identifying the location of stenosis as identified by coronary angiography.

    28 days

Interventions

0.175 mg/kg diluted in 150 mL Dextrose in Water 5% in glass bottles to be infused at 250 mL/hour until stead state achieve, 150 mL/hour during rest image acquisition, and 100-150 mL/hr during stress image acquistion. Single IV infusion, not to exceed 60 minutes.

Also known as: CARDIOsphere®
