In April 2008, a coronary catheter based imaging system, LipiScan, was cleared by the FDA for use in detecting lipid core containing containing plaques of interest (LCP). These plaques are rich in cholesterol. The way that cholesterol and other lipids deposit with the coronary artery is unique to each patient. This study is an organized attempt to observe the LCP and the variety of ways that it presents in patients as detected by this recently approved device. This information will be used for physician training and to observe the behavior of the LCP in response to no therapy and currently approved therapies. The purpose of this project is further medical knowledge of the LCP and its treatment.

Further study details as provided by InfraReDx:

Primary Outcome Measures:
  • Identify associations of LCP with angiographic or symptomatic presentation of coronary artery disease in a catheterization laboratory population [ Time Frame: after completion of the study - during data analysis ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Identification of associations that LCP or the Lipid Core Burden Index (LCBI) may have with atherosclerosis appearance, progression, regression, and/or cardiac event [ Time Frame: Upto 2 years post procedure(baseline) ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 2000
Study Start Date: February 2009
Primary Completion Date: February 2016 (Final data collection date for primary outcome measure)
