Factors determining the quality of life after pacemaker implantation
Abstract
Introduction. Health-related quality of life (HRQoL) after pacemaker (PM) implantation has been studied according to stimulation mode and indications, however these do not fully explain HRQoL changes. Aim of the study is to evaluate other factors.
Materials and methods. Single-center, prospective, observational study on 101 adult PM-recipients, with no periproce- dural complications was performed. The study group was surveyed twice: periprocedural and 18 month follow-up (FU). Nottingham Health Profile to evaluate general HRQoL was performed. 83 participants completed full study protocol. Comparative analysis (periprocedural vs. end-of-FU) was performed to measure relationship between HRQoL-change and gender, place of residence, disability level, physical activity, level of care and support, BMI, diet, percentage of atrial and ventricular pacing (Ap&Vp), symptoms associated with rhythm and conduction disorders, severity of coronary heart disease and heart failure.
Results. Total HRQoL improvement occurred for the rural residents, obese and Vp > 79%. The study group improved significantly in two HRQoL domains: emotional reactions (E.R.) and sleep disorders (S.D.). Analyzing specific HRQoL do- mains (energy, pain, E.R.S.D. social alienation, movement limitations) improved patients are: female, self-mobile, high level of care and support, eating habits — changers, without syncope and angina symptoms. Age and body mass index (BMI) were identified as factors changing HRQoL-improving domain.
Conclusions. The improvement of HRQoL after PM implantation seems to be mainly related to S.D. and E.R. Important factors influencing HRQoL change are: place of residence, BMI and Vp. This impact of PM implantation on HRQoL re- quires further study
