Effects of Angiotensin-Converting Enzyme Inhibitor (Ramipril) Therapy on Blood Vessel Inflammation
NCT00005928 · View on ClinicalTrials.gov ↗
Study Summary
This study will determine the effects of angiotensin-converting enzyme (ACE) inhibitor (trade name Ramipril) therapy on inflammation and stiffness of artery walls. These are two risk factors for developing atherosclerosis-deposits of fatty substances called plaques that can block the blood vessel, causing a heart attack or stroke. Studies of patients with coronary artery disease suggest that ACE inhibitor therapy reduces the risk of heart attack and heart failure. This study will examine the effects of this treatment on the artery walls and on levels of substances in the blood that indicate blood vessel inflammation. Patients between 40 and 75 years old with coronary artery disease caused by atherosclerosis may be eligible for this study. Candidates will be screened with a medical history, cardiovascular (heart and blood vessel) examination, electrocardiogram and blood tests. Those enrolled will be randomly assigned to take either an ACE inhibitor pill or a placebo (look-alike pill with no medicine) once a day for 3 months. No pills will be taken for the next month, and then participants will take the alternate pill for the next 3 months. That is, those who took ACE inhibitor for the first 3-month period will take placebo for the second 3-month period and vice versa. Blood pressures will be taken at the NIH Clinical Center or by the patient's physician at the end of the first and second weeks of the study. At the end of 3 weeks, patients will return to the Clinical Center for a blood draw of 6 cc (1/2 teaspoon) to assess kidney function. In addition, at the end of each 3-month study period, patients will undergo the following procedures at the Clinical Center: 1. Fasting blood draw of 60 cc (2 ounces) to measure electrolytes (e.g., sodium and potassium) and blood markers for inflammation 2. Ultrasound (use of sound waves to create pictures) study of the carotid arteries (arteries in the neck leading to the brain)-An ultrasound probe is applied gently on the neck,

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00005928
The ClinicalTrials.gov registry entry for NCT00005928 describes a study currently listed as completed. It is categorized as Phase 2, 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 25 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 3 conditions, with Atherosclerosis appearing as the primary indexed condition, and to 1 intervention — of which Ramipril is the first listed. 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: NCT00005928 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.
