Quality of life in patients with paroxysmal atrial fibrillation and its predictors: importance of the autonomic nervous system

Abstract

Aims To determine the impact of paroxysmal atrial fibrillation on quality of life and to determine the predictors of quality of life, particularly the role of symptomatology and autonomic function. Methods and Results The study group comprised 73 patients with paroxysmal atrial fibrillation (mean age 54·1 years, 51 males). On average, patients had a 3-year history of one paroxysm per week lasting 2h. Quality of life was assessed using the SF-36 (Medical Outcomes Study Short-Form Health Survey) and compared with age-matched controls. Autonomic function was assessed using Holter monitoring with analysis of heart rate variability and autonomic function tests. Symptoms during paroxysms of atrial fibrillation were also scored. Multivariate analysis was performed to identify independent predictors of quality of life. Quality of life scores were markedly lower in patients than in controls in four of the eight subscales (PPPConclusions This study shows that paroxysmal atrial fibrillation causes significant impairment of quality of life. Further, symptomatology and autonomic function are important predictors of quality of life in this patient group.
