Lifetime Risk of Atrial Fibrillation by Race and Socioeconomic Status: ARIC Study (Atherosclerosis Risk in Communities).

ABSTRACT:

Background

Limited information exists on the lifetime risk of atrial fibrillation (AF) in African Americans and by socioeconomic status.

Methods

We studied 15 343 participants without AF at baseline from the ARIC (Atherosclerosis Risk in Communities) cohort recruited in 1987 to 1989 from 4 communities in the United States when they were 45 to 64 years of age. Participants have been followed through 2014. Incidence rates of AF were calculated dividing the number of new cases by person-years of follow-up. Lifetime risk of AF was estimated by a modified Kaplan-Meier method considering death as a competing risk. Participants' family income and education were obtained at baseline.

Results

We identified 2760 AF cases during a mean follow-up of 21 years. Lifetime risk of AF
