Decade-long trends in atrial fibrillation incidence and survival: a community study.

ABSTRACT:

Background

Contemporary data on temporal trends in incidence and survival after atrial fibrillation are scarce.

Methods

Residents of Olmsted County, Minn., with a first-ever atrial fibrillation or atrial flutter event between 2000 and 2010 were identified. Age- and sex-adjusted incidence rates were standardized to the 2010 US population, and the relative risk of atrial fibrillation in 2010 versus 2000 was calculated using Poisson regression. Standardized mortality ratios of observed versus expected survival were calculated, and time trends in survival were examined using Cox regression.

Results

We identified 3344 patients with incident atrial fibrillation/atrial flutter events (52% were male, mean age 72.6 years, 95.7% were white). Incidence did not change over time (
