入选标准

  • 18 years old or older and able to provide written informed consent;
  • All subjects must be scheduled for or have undergone SPECT within 28 days prior to or following Study Day 1
  • Subjects with very low/low pre-test probability of coronary artery disease must consent to participate in the extension trial 127-014-A
  • 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
  • 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
  • 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
  • Sinus rhythm at the time of the study procedure
  • Adequate visualization of myocardial segments
  • Appropriate candidate for stress testing according to ACC/AHA Guidelines for Exercise Testing

排除标准

  • Women who are pregnant or lactating
  • Known hypersensitivity or known contraindication to:
  • Dipyridamole
  • Ultrasound contrast agents (including PB127 and excipients)
  • Blood, blood products, albumin, egg, or protein
  • Use of caffeine or xanthine containing products within the 24 hours prior to Study Day 1
  • Previous exposure to PB127 Ultrasound Contrast Agent
  • Major surgery within 7 days prior to Study Day 1 (requiring general anesthesia and/or overnight stay)
  • Heart transplant or history of CABG
  • Known hemodynamically significant or symptomatic right-to-left shunt (including shunts that are associated with prior TIAs or strokes)
  • Recent history of sustained ventricular tachycardia
  • Pacemaker or defibrillator
  • Unstable cardiac status
  • 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
  • Decompensated heart failure
  • Second-degree or greater heart block, sick sinus syndrome
  • Frequent (>60/hour) or symptomatic ventricular ectopics at baseline
  • Hypertension (SBP >200 and/or DBP >110 mmHg on two consecutive readings within one hour of PB127 MPE)
  • Hypotension (SBP <90 mmHg)
  • Severe aortic stenosis (>40 mmHg mean gradient or <0.6 cm2/m2 valve area index)
  • Pulmonary edema within the 7 days prior to Study Day 1
  • Resting oxygen saturation of less than 90% on room air
  • Myocardial infarction or cerebral vascular accident / transient ischemic attack within the 28 days prior to Study Day 1
  • Chronic Obstructive Pulmonary Disease (COPD) or bronchospastic airway disease, which in the opinion of the Investigator, is significant enough to contraindicate dipyridamole
  • Known history of severe pulmonary hypertension characterized by estimated pulmonary artery systolic pressure of >50 mmHg
  • Liver disease characterized by one or more of the following
  • Current jaundice
  • Elevated bilirubin > upper limit of normal
  • Currently elevated hepatic enzymes > 2X upper limit of normal
  • Current or previous hepatic viral infection (not including hepatitis A)
  • Chronic hepatitis
  • 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.

时间窗: 72 hours, 6 months

次要结局

  • To compare the diagnostic performance of PB127 MPE to SPECT for the detection and/or exclusion of significant obstructive coronary artery disease.(72 hours, 6 months)
  • To assess the concordance of PB127 MPE with SPECT in the differentiation of defect type (fixed versus reversible) in patients with significant obstructive CAD.(72 hours, 6 months)
  • To evaluate the diagnostic performance characteristics of PB127 MPE for identifying the location of significant obstructive CAD as defined by quantitative coronary angiography(72 hours)
  • To assess the change in diagnostic certainty when PB127 MPE and relevant clinical information are combined over relevant clinical information alone.(72 hours, 6 months)
