Association Between Atrial Fibrillation and Costs After Myocardial Infarction: A Community Study.

ABSTRACT:

Background

The authors sought to estimate incremental economic impact of atrial fibrillation (AF) and the timing of its onset in myocardial infarction (MI) patients.

Hypothesis

Concurrent AF and its timing are associated with higher costs in MI patients.

Methods

This retrospective cohort study included incident MI patients from Olmsted County, Minnesota, treated between November 1, 2002, and December 31, 2010. We compared inflation-adjusted standardized costs accumulated between incident MI and end of follow-up among 3 groups by AF status and timing: no AF, new-onset AF (within 30 days after index MI), and prior AF. Multivariate adjustment of median costs accounted for right-censoring in costs.

Results

The final study cohort had 1389 patients, with 989 in no AF
