Health-related quality of life of patients with permanent cardiac pacing

Abstract

Objective: to assess the health-related quality of life of patients with a permanent cardiac pacemaker. Method: descriptive, observational, cross-sectional study conducted in the arrhythmia outpatient unit of a university hospital located in the interior of São Paulo, Brazil. The consecutive and non-probabilistic sample was composed of both sexes, older than 29 years old, having a pacemaker for at least one month. Those lacking the cognitive condition to answer the questionnaires, as well as those with dyspnea, weakness, or fatigue at the time the instruments were applied, or with an implantable cardioverter defibrillator, were excluded. The generic instrument Medical Outcomes Study 36-Item Short-Form Health Survey, composed of 36 questions distributed into eight domains along with the specific instrument Assessment of Quality of Life and Related Events, composed of 20 questions distributed into three domains, were used to assess health-related quality of life. Results: 88 patients participated; most were men, had a partner, and were aged 64.3 (±13) years old on average. The domains from the Medical Outcomes Study 36 that obtained the highest means, that is, were the best-rated, were Social Functioning (78.1; ±26.8) and Emotional Well-Being (68.2; ±23.9), while the lowest means were obtained by Physical Health (48.2; ±41.4) and Physical Functioning (58.5; ±27.9). In regard to the Assessment of Quality of Life and Related Events, the Arrhythmia domain had the highest mean and best quality of life (78.2; ±20.7), while the lowest mean was Dyspnea (71.1; ±26.8). Conclusion: the patients gave the highest health-related quality of life ratings in regard to mental domains and the lowest ratings for the physical domains.
