Sumary of I-STOP-AFIB: No effect of trigger testing on AF-related quality of life, but fewer events:

  • Disclosures: The I-STOP-AFIB trial was funded by the Patient-Centered Outcomes Research Institute (PCORI), which also participated in trial design.
  • Marcus reports receiving research funding from Baylis Medical, California Tobacco-Related Disease Research Program, Eight Sleep, Medtronic, NIH and PCORI;
  • Back to Healio Patient-selected trigger testing for paroxysmal atrial fibrillation did not improve AF-related quality of life, but the process was tied to fewer self-reported AF events in the weeks after trial participation, a speaker reported.
  • According to results presented at the American Heart Association Scientific Sessions, patients were able to select which AF triggers to test, and although caffeine was the most commonly selected exposure, alcohol was the only exposure with a strong association with AF events.
  • Source: Adobe Stock A total of 446 participants with paroxysmal AF who were interested in choosing and testing their own idiosyncratic AF triggers were enrolled into the I-STOP-AFIB trial (mean age, 58 years;
  • For the program of 10 weeks or more, participants were instructed to expose themselves to or avoid self-selected AF triggers for random 1-week intervals.
  • Researchers then communicated to the participants the probability of their trigger influencing AF risk.
  • Self-reported incident AF was assessed daily using a smartphone-based ECG monitoring device (KardiaMobile, AliveCor).
