Adaptive blood pressure–modulated atrial pacing in hypertensive heart failure with preserved ejection fraction (HFpEF) patients: a randomized, first-in-human study

ESC Heart FailPublished

  • prospective, double-blind, randomized, self-controlled crossover study
  • first-in-human

Authors' conclusion

In hypertensive patients with HFpEF and implanted pacemakers, BPAP safely improved exercise capacity and functional status compared to standard pacing. The approach demonstrates feasibility of home-based blood pressure-modulated pacing for physiologic rate adaptation. (NCT06036186)

Study context

Population
Patients with treated hypertension and HFpEF with implanted dual-chamber pacemakerspatients, each underwent two 3-week treatment phases in random order
