The Effectiveness of Patch-Based Screening for Pre-Symptomatic Atrial Fibrillation to Improve Patient Outcome

CSP #2037S - Veterans Affairs Learning Health System Initiative to Assess Novel Screening vs. Usual Care and Treatment With Apixaban vs. Rivaroxaban in Veterans With Atrial Fibrillation (VALIANT-AF-S) Trial

Source: ClinicalTrials.gov · Last updated 30 Jun 2026

Brief summary (registry, in English)

* The goal of the screening trial is to determine whether early screening for atrial fibrillation improves outcomes, including lowering the chance of death, hospitalization for stroke, blood clots, heart failure, heart attack, and severe bleeding reduces the risk of stroke or heart failure. * Atrial fibrillation is a common heart condition in which one of the heart chambers doesn't follow a normal rhythm. Blood clots can form as a result, and they can travel to the brain and cause strokes, or to other organs. * Almost everyone with atrial fibrillation is treated with drugs called anticoagulants ("blood thinners") to reduce the risk of stroke. These drugs also increase the risk of bleeding. * Testing for atrial fibrillation is usually done for patients who have symptoms of an irregular or unusually fast or slow heartbeat, often called "palpitations" or a sensation of the heart pounding or stopping for a short period of time. * What is not known is whether screening people who do not have symptoms of atrial fibrillation, but who are at above-average risk of getting atrial fibrillation, will reduce death, hospitalization for stroke, blood clots, heart failure more than it increases hospitalization for severe bleeding. * People who participate in the trial who are selected by chance to receive screening will wear a small heart-rate monitor (Zio Patch) on their skin for 14 days and then return it to the manufacturer. Their doctors will be notified about the results and will make decisions about any treatment to recommend. * The screening trial is expected to enroll about 24,000 VA patients nationwide and to last 7 years, but each person's active participation in the trial is completed after sending in the Zio Patch. After that, the study team will just collect information from the participant's electronic medical records.

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • Cardio-thoracic surgery in the prior 3 months

Other illness

  • Presence of pacemaker, implantable defibrillator, or implanted cardiac monitor
  • Clinically significant allergy to adhesives, as reported by the patient during screening for trial enrollment

Other

  • An individual who meets any of the following criteria will be excluded from participation in this study:
  • Current use of anticoagulation
  • Diagnosis of AF (from administrative records or per patient during consent)
  • Planned use of a brain or spinal-cord stimulator, TENS unit, or MRI scan during the period when the Zio Patch will be worn

Who the study is looking for

  • To be eligible to participate in this study, an individual must meet all of the following criteria:
