Observational Study on Long-Term Atrial Fibrillation After Acute Illness

This study is looking at how often atrial fibrillation (AF), a type of irregular heartbeat, comes back in people who have had it after a recent illness. Researchers are observing patients who already need an insertable cardiac monitor (ICM) – a small device placed under the skin to track heart rhythm – as part of their regular medical care. Specifically, they are using the Boston Scientific LUX-DX™ ICM. The main goal is to see how long it takes for AF to return within 12 months. You might be able to join if you are 18 or older, have had acute AF, and are scheduled to get or have already received a Boston Scientific LUX-DX™ ICM for clinical reasons. The study is currently unclear on its recruitment status and plans to include 100 participants.

Study design

What this trial measures

  • Time to first documented event of AF by 12 months12 months

    The primary objective is to determine the time to first documented event of AF by 12 months of continuous rhythm monitoring, stratified by the setting of acute AF diagnosis (cardiac surgery, non-cardiac surgery, and medical illness).
