An Observational Study of Cholesterol in Coronary Arteries (COLOR)

This study is ongoing, but not recruiting participants.

Last verified: August 2016
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.

Condition Intervention
Myocardial Infarction
Coronary Artery Disease
Myocardial Ischemia
Device: Intravascular Near Infrared Spectroscopy

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Chemometric Observation of Lipid Core Plaques of Interest in Native Coronary Arteries Registry

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 ]

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) ]

Enrollment: 2067
Study Start Date: February 2009
Estimated Study Completion Date: November 2016
Primary Completion Date: February 2016 (Final data collection date for primary outcome measure)

Exclusion Criteria:

  • Subject is pregnant or nursing.
  • Subject life expectancy is less than 2 years at time of index catheterization.
  • All submitted chemograms are obtained with the LipiScan, LipiScan IVUS, or TVC(R) Imaging Catheter positioned within a coronary artery bypass graft.
  • Unable to give informed consent
