MHMasaru Hiki SKSharma Kattel ASAkihiro Sato

Key Result

Pacemaker implantation improved subjective sleep quality in patients with bradyarrhythmia, enhancing overall quality of life.

Key Points

The research aims to investigate subjective sleep quality in bradyarrhythmia patients and the effects of pacemaker implantation on it.
Assessment of sleep quality before and after pacemaker implantation
Evaluation of quality of life in patients
Longitudinal analysis comparing pre- and post-intervention sleep scores
Patients reported improved sleep quality after pacemaker implantation
Quality of life also showed significant enhancement post-implanation
Correlation between pacemaker use and better overall sleep metrics observed

Structured PICO

Does permanent cardiac pacemaker implantation improve subjective sleep quality and health-related quality of life in patients with symptomatic bradyarrhythmia?

Population

89 patients with symptomatic bradyarrhythmia (complete or advanced atrioventricular block, sick sinus syndrome, and atrial fibrillation with bradycardia) scheduled for elective permanent cardiac pacemaker implantation, mean age 76.5, 57.3% female, based in Japan. Excluded: heart failure requiring treatment for acute decompensation, severe valvular heart disease, stroke, chronic pulmonary disease, uncured malignancy, dialysis, or treatment for psychiatric or sleep disorders.

Intervention

Permanent cardiac pacemaker implantation (89.9% received dual-chamber DDD pacemakers)

Outcome

Changes in subjective sleep quality (assessed by the Pittsburgh Sleep Quality Index [PSQI]) and health-related quality of life (assessed by Short Form-8 [SF-8]) at follow-up (median 41 days post-implantation)patient reported

Permanent pacemaker implantation in patients with symptomatic bradyarrhythmia significantly improves subjective sleep quality and mental health-related quality of life.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

Poor subjective sleep quality is common among patients with bradyarrhythmia, contributing to impaired QOL. Pacemaker implantation may have a favorable effect on subjective sleep quality, and QOL for such patients.
