Effect of anxiety and depression on the fatigue of patients with a permanent pacemaker.

INTRODUCTION

Permanent cardiac pacemakers (PPM) are the most common treatment for severe symptomatic bradycardia. This implanted life-saving device may involve a severe psychological burden to recipients or aggravate their symptoms such as fatigue. The aim of the study was to explore the effect of anxiety and depression on fatigue of patients' with a PPM.

MATERIAL AND

METHODS

The study group consisted of 250 patients with a PPM. Data collected included: a) patients' characteristics, b) the Hospital Anxiety and Depression Scale (HADS) and c) the Fatigue Assessment Scale (FAS).

RESULTS

High levels of anxiety and depression were observed in 27.2% and 14.0% of the sample, respectively. Regarding the fatigue total score it was found that 25% of the participants had a score higher than 26. Accordingly, with regard to physical and mental fatigue, 25% of enrolled patients had a score higher than 20 and 8, respectively. These values indicate moderate to low levels of fatigue. Furthermore, there was a statistically significant association between anxiety/depression and the total score of fatigue as well as between anxiety/depression and physical and mental fatigue (p < 0.001 for all associations).

CONCLUSIONS

Socio-demographic and patients' clinical characteristics are related to anxiety and depression. Understanding the association between psychological burden and fatigue after implantation as well as factors associated with these variables will help health professionals to provide beneficial care for PPM patients that will significantly contribute to better device outcomes.
