Post-PCI:Cardiac Imaging in Patients With Diabetes to Detect Coronary Artery Blockages Previously Opened by Angioplasty

Cardiolite-406; A Phase IV Open-Label, Randomized, Multi-Center Trial To Evaluate The Ability of Cardiolite Stress MPI to Detect Asymptomatic Restenosis in Diabetic Patients Who Have Undergone Percutaneous Coronary Intervention

The purpose of this clinical research study is determine if patients with diabetes that have undergone previous opening of a heart blockage may have a blockage that is not causing any symptoms that may be detected by imaging with Cardiolite.

Inclusion Criteria:

• Type II Diabetes on medication & angioplasty within the past 6 months.

Exclusion Criteria:
