We found no evidence of a temporal trend in hazard ratios between newly diagnosed atrial fibrillation and all cause mortality. The hazard ratios for non-cardiovascular death declined over time but no evidence of a temporal trend for cardiovascular death was found. Mortality associated with newly diagnosed atrial fibrillation remained high compared with individuals without atrial fibrillation, despite showing some improvements over the past 45 years. More than 10 years after a diagnosis of atrial fibrillation, individuals with atrial fibrillation lose about two years of life compared with matched referents.
