Myocardial InfarctionCOLORNCT00831116
An Observational Study of Cholesterol in Coronary Arteries
An observational study of Myocardial Infarction and Angina, run by Infraredx at 22 sites in United States.
Trial summary
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. Read more about this study

About this study
Official title: Chemometric Observation of Lipid Core Plaques of Interest in Native Coronary Arteries Registry
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.

Questions about this trial
What is this clinical trial studying?
An observational study of Myocardial Infarction and Angina, run by Infraredx at 22 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 22 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
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). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jun 2017; AzTrials last refreshed its copy on 7 Nov 2026.
