This study aimed to investigate the association between health status and subsequent clinical events among patients with atrial fibrillation (AF).
BACKGROUND Clinical practice guidelines recommend optimizing the health status of patients with atrial fibrillation (AF) as a primary treatment goal. Whether disease-specific health status is associated with subsequent clinical events is unknown.OBJECTIVES The aim of this study was to investigate the association between health status and subsequent clinical events among patients with AF.METHODS Using a prospective cohort study of patients with new-onset AF referred to 11 hospitals (n 1/4 3,313, 68.4% men, mean age 67.8 +/- 11.6 years), data were extracted from 3,296 patients (99.4%) who completed the disease-specific Atrial Fibrillation Effects on Quality-of-Life (AFEQT) questionnaire between 2012 and 2018. Factors associated with baseline AFEQT overall summary (OS) score and associations between major adverse cardiovascular or neurologic events (MACNE; a composite of all-cause death, stroke, or new-onset heart failure hospitalization) over 2 years were investigated.RESULTS Overall, 517 participants (15.6%) had poor to fair health status (AFEQT OS <60), and 1,035 (31.2%) had fair to good health status (AFEQT OS 60 to <80) at baseline. Female sex, younger age, family history of AF, higher baseline heart rate, paroxysmal AF, initial visit to the emergency department, and history of heart failure were associated with lower AFEQT OS scores. Of those, 226 participants (6.8%) experienced MACNE; restricted cubic spline analysis with adjustment for factors associated with baseline AFEQT score showed a nonlinear increase in the risk for MACNE with AFEQT OS score <80. The strongest associations were observed for baseline AFEQT daily activity scores (for AFEQT daily activity score of <80 vs $80, HR: 1.65; 95% CI: 1.21-2.25).CONCLUSIONS Diminished health status in patients with AF is common and is independently associated with subsequent adverse cardiovascular events.
