D-PO02-084 - The Role Of Cardiac Rehabilitation In Patients Undergoing Pacemaker Implantation: A Preliminary Data From Single Center Randomized Controlled Trial (ID 1006)

 J. Ahn: Nothing relevant to disclose.


Background: Although patients requiring pacemaker (PM) are at risk of a sedentary lifestyle due to fear of bradycardia-induced symptoms, the role of cardiac rehabilitation (CR) in these populations is not known.
Objective: We conducted this study to evaluate beneficial effects of CR early after PM implantation.
Methods: This study is a single-center, randomized clinical trial and still recruiting eligible patients since April in 2018. A total of 24 patients with 6-minute walking distance (6MWD) less than 85% of predicted value on the next day of PM implantation were enrolled and randomly assigned to CR group (n=10, 41.7%) or non-CR group (n=14, 58.3%). The CR group trained a total of 8 times of individualized exercise-based CR for 1 month. SF-36, 6MWD, muscle power, and cardiopulmonary exercise test (CPET) at baseline and 1 month follow-up period were compared between inter- and intra-groups.
Results: Patients in CR group were older, but there were no differences in PM indication, SF-36 score, 6MWD, muscle power, or CPET parameters on baseline between groups. After a mean follow-up period of 36.5 days, both groups showed significantly improved 6MWD from baseline. In CPET, percent of VO2 max was significantly higher in CR group (75.8% vs. 60.7%, p=0.041, Figure). In addition, only CR group showed improved quality of life (vitality 9 to 12.3, p=0.045; mental health score 14.3 to 21.0, p=0.011), unlike the non-CR group. Lead dislodgement or change in PM parameter was not shown in any patient.
Conclusion: Post-PM early CR seemed to improve exercise capacity and quality of life in some parts without any PM-related complications in patients with PM implantation.
