Vascular Events In Patients Undergoing Same-day Noncardiac Surgery (VALIANCE) Study
NCT04973397 · View on ClinicalTrials.gov ↗
Study Summary
The proportion of noncardiac surgeries performed as same-day surgery is increasing worldwide, with more complex surgeries being performed on higher risk patients in the outpatient setting. Little is known on the risk factors, incidence and prognosis of patients undergoing same-day noncardiac surgery. The main objective of this study is to inform on the incidence and risk factors of cardiovascular and other adverse events after same-day surgery and to develop risk prediction tools to better inform on the risk and selection of patients undergoing same-day surgery.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04973397
The ClinicalTrials.gov registry entry for NCT04973397 describes a study currently listed as recruiting. 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 15,000 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Centre hospitalier de l'Université de Montréal (CHUM), which has 7 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 Myocardial Infarction 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: NCT04973397 reports 16 study locations spanning 6 distinct geographic areas — top geographies include Ontario, Ohio, Texas. 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.
