The adjusted hazard of AF was similar between Black and White individuals with CIEDs.
Study context
- Population
- Black and White patients with a CIED capable of atrial fibrillation (AF) diagnosis implanted between January 1, 2007, and June 1, 2019; patients with insertable cardiac monitors, insufficient monitoring or prior AF excludedof 441,047 with a CIED
- Participants
- 88,427 participants
- Exposure
- Black vs White individuals
- Whiten = 80,382reference
- Outcome
- Overall adjusted incidence of device-detected AF, Black vs White
- Follow-up
- Mean 2.2 ± 1.7 years
