Nitric Oxide Inhalation Therapy to Relieve Chest Pain in Patients With Coronary Artery Disease
NCT00014040 · View on ClinicalTrials.gov ↗
Study Summary
This study will test whether inhaling nitric oxide gas can improve blood flow to the heart, ventricular function, exercise tolerance in patients with coronary artery disease and chest pain that has not improved with medical or surgical therapy. Patients with coronary artery disease who have chest pain despite treatment with medicines and angioplasty or surgery may be eligible for this study. Those enrolled will receive monetary compensation for their participation in this study. The duration of the study is 5 days, with 2 testing periods lasting 2 days each. During one of the periods, the study participants will breathe nitric oxide mixed with room air through a face mask during the tests. During the other period, the participants will breathe room air alone through a face mask during the tests. At least 1 day will separate the treatment periods. During each of the 2 treatment periods (nitric oxide and room air), participants will undergo 4 tests to determine whether the treatment improves the heart's response to stress with increased heart rate and contraction. Approximately one hour before each of the tests, participants will breathe either nitric oxide mixed with room air or room air alone through the face mask, and continue the inhalation treatment while each test is being performed. The face mask will be removed at the end of each test. On the morning of the first day of each treatment period, participants will have a special echocardiogram with imaging of the heart. The echocardiogram will be performed during an infusion of dobutamine, a medicine that increases heart rate and contraction, and serves to stress the heart. This manner of stress testing is commonly used in hospitals around the country to determine if walls of the heart are receiving sufficient blood supply. That afternoon, participants will undergo a magnetic resonance imaging (MRI) study of the heart. The MRI will determine the heart's blood flow and contraction while receiving the same dosage

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00014040
The ClinicalTrials.gov registry entry for NCT00014040 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 2 conditions, with Coronary Disease appearing as the primary indexed condition, and to 1 intervention — of which Nitric Oxide and INOpulse Delivery System 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: NCT00014040 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.
