High-intensity Inspiratory Muscle Training as a Pre-cardiac Rehabilitation in Heart Disease
NCT06127147 · View on ClinicalTrials.gov ↗
Study Summary
Background/aim: Endothelial function is closely associated with coronary artery health among individuals being treated for heart disease. An impairment in endothelial function promotes arterial stiffening that directly contributes to elevated systolic blood pressure as a result of increased vascular resistance. Inspiratory muscle training is simply a form of training consisting of repeated inspirations against resistance. Inspiratory muscle training has also been applied to patients with chronic disease or as an additional therapy for cardiac rehabilitation and it has proven to be safe in these groups. Few studies in the literature examined the effects of high-intensity inspiratory muscle training in this population, however, these studies did not examine the direct effects of inspiratory muscle training on vascular function. To the best of our knowledge, the effects of inspiratory muscle training in patients with heart disease on endothelial function and arterial stiffness prior to starting cardiac rehabilitation have not been investigated. This study aims to investigate and interpret whether high-intensity inspiratory muscle training, beyond the usual care of heart disease, improves endothelial function and arterial stiffness. Methods: The study was designed as a randomized controlled trial. Patients will be allocated for inspiratory muscle training (IMT) with 60% of maximum inspiratory pressure (MIP) or sham inspiratory muscle training (Sham-control), for 4 weeks. In both groups, before and after 4-week training, cardiovascular functions will be measured and compared.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06127147
The ClinicalTrials.gov registry entry for NCT06127147 describes a study currently listed as completed. It is categorized as NA, 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 11 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Illinois at Chicago, which has 421 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 Artery Bypass Graft appearing as the primary indexed condition, and to 2 interventions — of which IMT 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: NCT06127147 reports 2 study locations spanning 1 distinct geographic area — top geographies include Illinois. 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.
