Evaluation and Optimization of PB127 Myocardial Perfusion Echocardiography on Ultrasound Systems
- Conditions
- Coronary Artery DiseaseHealthy
- Registration Number
- NCT00487903
- Lead Sponsor
- Point Biomedical
- Brief Summary
The purpose of this clinical trial is to evaluate various commercially available ultrasound systems and to identify imaging parameters to be used with these systems (along with the contrast agent PB127) as well as to further evaluate the safety of PB127.

-
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
