Data included records from 1,062,610 octogenarians; 317,161 nonagenarians; and 3,572 centenarians. Kaplan-Meier curves were used to estimate cumulative incidence of AF by age group, incidence rates were compared using log-rank tests, and Cox proportional-hazards model were used to estimate unadjusted hazard ratios. The primary outcome was AF incidence at > age 80; the secondary outcome was mortality.Abstract: RESULTS: Cumulative AF incidence rate was 5.0% in octogenarians, 5.4% in nonagenarians, and 2.3% in centenarians. Octogenarians and nonagenarians had a higher risk of AF incidence compared to centenarians (adjusted hazard ratio 8.74; 95% CI [6.31-12.04] and 2.98; 95%CI [2.17-4.1], respectively). The lowest hazard ratio for mortality in patients with AF compared to those without 2.3; 95% CI(2.3-2.4) in patients who are on antiplatelet and anticoagulant medication, and have a score of 0 on the Elixhauser comorbidity index score.Abstract: CONCLUSION: Although AF incidence increased with age, being a centenarian was associated with reduced incidence and compression of morbidity. Patients with AF had a higher adjusted mortality rate. However, data suggests that a regimen of anticoagulant and antiplatelet seems to reduce risk of mortality in patients with AF diagnosis.Abstract: Copyright This article is protected by copyright.
