Key result
Atrial fibrillation prevalence among patients undergoing PCI increased from 8.6% to 12.0% between 2005 and 2014 (P<.001), and was associated with higher in-hospital mortality and complications.
Why the study?
AF is the most common arrhythmia in patients undergoing PCI, and large administrative data may provide further insight into temporal trends in its prevalence and burden.
Is atrial fibrillation associated with worse in-hospital outcomes and higher resource use in patients undergoing percutaneous coronary intervention?
Population
Estimated 6 272 232 hospitalizations of patients undergoing PCI
Comparison
Patients with AF vs without AF
Design
Retrospective database study with crude and propensity-matched analyses

AF prevalence is rising among PCI patients with associated higher mortality; leaves open optimal periprocedural strategies.

Is atrial fibrillation associated with worse in-hospital outcomes and higher resource use in patients undergoing percutaneous coronary intervention?
p-value: p=<.001
Atrial fibrillation is increasingly prevalent among patients undergoing PCI and is consistently associated with higher in-hospital mortality, bleeding, and stroke.
Morita et al. (2019) conducted an observational in Atrial fibrillation in patients undergoing percutaneous coronary intervention (n=6,272,232). Atrial fibrillation vs. No atrial fibrillation was evaluated on Atrial fibrillation prevalence (p=<.001). Atrial fibrillation prevalence among patients undergoing PCI increased from 8.6% to 12.0% between 2005 and 2014 (P<.001), and was associated with higher in-hospital mortality and complications.
