Study Design

  • Large, prospective, randomized, controlled, multicenter study
  • 1274 consecutive pacemaker patients at 85 centers in Japan
  • Single- or dual chamber pacemaker indication according to Japanese guidelines
  • BIOTRONIK Evia devices
  • 1:1 randomization to Home Monitoring+remote follow-up or Home Monitoring+in-office follow-up
  • Regular biannual follow-ups in both arms
  • If needed, unscheduled in-office follow-ups initiated by patients or physicians or due to alerts notified by HM
  • 24 months follow-up duration

 

Key Result 1

The At-Home study demonstrated non-inferiority of exclusive remote follow-up over 2 years in comparison to continuous remote monitoring associated with in-office follow-ups for real-world pacemaker patients.

Key Result 2

The median (IQR) number of in-office follow-ups was 0.50 (0.50 – 0.63) in RFU and 2.01 (1.93 – 2.05) in CFU per patient-year (P<0.001).

Clinical Relevance

  • The At-Home study is the largest randomized trial to investigate pacemaker patient follow-up with Home Monitoring only for 2 years.
  • Follow-up of cardiovascular implantable electronic devices is the most frequent activity reported by cardiac electrophysiologists. By exclusively using Home Monitoring, the proportion of in-office  follow-ups can be significantly reduced for pacemaker patients.
  • Before At-Home, the main concern about extending the time between in-office follow-ups was that safety could be compromised. The At-Home results indicate that surveillance of a real-world pacemaker patient population exclusively based on Home Monitoring for 2 years is safe.
  • The At-Home results indicate that reducing the need for in-office follow-ups reduces the resource consumption of managing pacemaker patients.
Study Objective
  • To study safety and resource consumption of exclusive remote follow-up (RFU) in pacemaker patients for two years.
