Atherosclerosis in the Coronary and Carotid Arteries
NCT00080587 · View on ClinicalTrials.gov ↗
Study Summary
This study will compare changes in atherosclerotic plaque in the coronary arteries (vessels on the surface of the heart that supply blood to the heart) with changes in the carotid arteries (vessels in the neck that supply blood to the brain) in patients enrolled in a Pfizer-sponsored treatment trial for coronary artery disease. Atherosclerosis is a buildup of fatty deposits (plaque) in arteries that can lead to blockage of the vessel, possibly resulting in heart attack or stroke. A major question in cardiovascular disease is how closely atherosclerotic changes in the coronary arteries correlate with changes in the carotid artery that occur with treatment. substudy of a Pfizer. Patients enrolled in the Pfizer trial comparing the effectiveness of the drug atorvastatin with a combination of atorvastatin and CETP inhibitor (a drug to increase HDL cholesterol levels) may be eligible for this substudy. Participants undergo magnetic resonance imaging (MRI) and ultrasound of the carotid arteries to measure the thickness of the vessels. The results are then compared with the coronary artery images obtained as part of the patient's evaluation for the Pfizer trial. MRI MRI scans use a powerful magnet with an advanced computer system and radio waves to produce accurate, detailed pictures of organs and tissues. During the scan the patient lies on a table in a narrow cylinder containing a magnetic field, wearing earplugs to muffle loud noises that occur with electrical switching of the magnetic fields. A medicine called gadolinium contrast may be injected into a vein during part of the scan to brighten the images. The scan takes about 30 to 90 minutes. An electrocardiogram (ECG) is done during the scan to monitor the heart's electrical activity. Patients who agree to undergo another MRI test are also imaged in a scanner that uses a stronger (3 Tesla) magnet. Ultrasound An echocardiogram (ultrasound of the heart) uses sound waves to image the carotid arteries. A gel is appli

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00080587
The ClinicalTrials.gov registry entry for NCT00080587 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 125 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Heart, Lung, and Blood Institute (NHLBI), which has 381 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Coronary Disease appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00080587 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
