You may be eligible if
1. 18 years old or older and able to provide written informed consent;
2. All subjects must be scheduled for or have undergone SPECT within 28 days prior to or following Study Day 1
3. Subjects with very low/low pre-test probability of coronary artery disease must consent to participate in the extension trial 127-014-A
4. Subjects with very low/low pre-test probability of coronary artery disease must not have a current diagnosis of obstructive CAD on angiogram or prior MI
5. Subjects with very low/low pre-test probability of coronary artery disease with a current diagnosis of obstructive CAD on angiogram or prior MI may be enrolled into Stratum 2
6. Subjects with intermediate or high pre-test probability of coronary artery disease must be scheduled for coronary angiography within the 28 days following Study Day 1
7. Sinus rhythm at the time of the study procedure
8. Adequate visualization of myocardial segments
9. Appropriate candidate for stress testing according to ACC/AHA Guidelines for Exercise Testing
You may not be if
1. Women who are pregnant or lactating
2. Known hypersensitivity or known contraindication to:
1. Dipyridamole
2. Ultrasound contrast agents (including PB127 and excipients)
3. Blood, blood products, albumin, egg, or protein
3. Use of caffeine or xanthine containing products within the 24 hours prior to Study Day 1
4. Previous exposure to PB127 Ultrasound Contrast Agent
5. Major surgery within 7 days prior to Study Day 1 (requiring general anesthesia and/or overnight stay)
6. Heart transplant or history of CABG
7. Known hemodynamically significant or symptomatic right-to-left shunt (including shunts that are associated with prior TIAs or strokes)
8. Recent history of sustained ventricular tachycardia
9. Pacemaker or defibrillator
10. Unstable cardiac status
1. Unstable angina grade CCS Class IV severity (any physical activity causes limiting symptoms; symptoms may be present at rest in a patient with prior exertional angina) with ongoing symptoms and/or ongoing infusion of intravenous nitroglycerin
2. Decompensated heart failure
3. Second-degree or greater heart block, sick sinus syndrome
4. Frequent (\>60/hour) or symptomatic ventricular ectopics at baseline
5. Hypertension (SBP \>200 and/or DBP \>110 mmHg on two consecutive readings within one hour of PB127 MPE)
6. Hypotension (SBP \<90 mmHg)
7. Severe aortic stenosis (\>40 mmHg mean gradient or \<0.6 cm2/m2 valve area index)
8. Pulmonary edema within the 7 days prior to Study Day 1
9. Resting oxygen saturation of less than 90% on room air
11. Myocardial infarction or cerebral vascular accident / transient ischemic attack within the 28 days prior to Study Day 1
12. Chronic Obstructive Pulmonary Disease (COPD) or bronchospastic airway disease, which in the opinion of the Investigator, is significant enough to contraindicate dipyridamole
13. Known history of severe pulmonary hypertension characterized by estimated pulmonary artery systolic pressure of \>50 mmHg
14. Liver disease characterized by one or more of the following
1. Current jaundice
2. Elevated bilirubin \> upper limit of normal
3. Currently elevated hepatic enzymes \> 2X upper limit of normal
4. Current or previous hepatic viral infection (not including hepatitis A)
5. Chronic hepatitis
15. Medical conditions or other circumstances that would significantly decrease the chances of obtaining reliable data or achieving the study objectives (i.e., drug dependence, psychiatric disorder, dementia, or associated illness); extenuating circumstances or medical conditions that make it unlikely that a patient can complete the clinical trial or follow up evaluations; or other reasons for expected poor compliance with the clinical investigator's instructions.
