Why the study?

Because AF is often asymptomatic and may remain undiagnosed until or after complications such as stroke occur, observed AF prevalence may underestimate total disease burden.

Study Design

Type

Cohort (n=1,500,000)

Structured PICO

P

Population

1.5 million working-age and elderly adults in the United States with continuous health insurance enrollment, analyzed to estimate the prevalence of undiagnosed atrial fibrillation.

O

Outcome

Estimated prevalence of undiagnosed atrial fibrillation (AF)

Limitations

Assumed that all AF detected in the three months after ischemic stroke was present prior to stroke
May have underestimated the prevalence of undiagnosed AF since silent strokes, short episodes of AF, or cryptogenic strokes were not fully captured
Modeled from data sources that may not be truly representative of the U.S. population
Did not account for differences in stroke event rates by race or ethnicity
Assumed that stroke incidence rates among patients with undiagnosed AF were similar to those of patients with diagnosed AF
Data available to the authors at the time of research was only through 2010
Assumed all AF detected in the three months after ischemic stroke was present prior to stroke
May have underestimated prevalence due to silent strokes, short AF episodes, or cryptogenic strokes
Data sources may not be truly representative of the U.S. population
Data only available through 2010
Relies on the accuracy of the back-calculation model

Implication

Using a back-calculation approach from ischemic stroke events, an estimated 5.3 million people in the US had atrial fibrillation in 2009, of which 13.1% (700,000) were undiagnosed, suggesting a higher true prevalence than previously estimated.
