Sumary of Tracking potential triggers of atrial fibrillation could lead to fewer episodes:
- Atrial fibrillation(AFib) is an irregular or quivering heartbeat that can lead to blood clots, stroke, heart failure and other heart-related complications.
- In the I-STOP-AF Trial, “Individualized Studies of Triggers of Atrial Fibrillation: A Randomized Controlled Trial,” researchers set out to determine whether monitoring potential triggers could reduce AFib episodes.
- S., study’s lead author, a professor of medicine, University of California, San Francisco School of Medicine and associate chief of cardiology for research, UCSF Health Researchers initially enrolled 446 participants in the trial, with 320 completing the study.
- They performed a remote, mobile application-based trial, and patients were randomly assigned to either monitor their AFib episodes without tracking their presumed triggers, or to test whether specific “triggers” affected or caused atrial fibrillation episodes.
- This process was randomized over a six-week period, and all participants reported daily about any atrial fibrillation episodes.
- Related StoriesAt the conclusion of the first six weeks of the trial, participants received their results on the probability that their presumed trigger did or did not influence the chance of experiencing an AFib episode.
- At the end of week 10 of the trial, both groups completed a questionnaire about the severity of their atrial fibrillation.
- The study’s findings include: Patients who completed the individualized trigger study reported less frequent episodes of atrial fibrillation during the four weeks after their testing compared to those who only tracked AFib episodes.
