Study summary

The results of this study could imply that a atrial fibrillation registry, as a tool for structured diagnosis and therapy in patients with atrial fibrillation, may improve patient care for this rapidly growing population.

Read the detailed description

Atrial fibrillation is the most common cardiac arrhythmia and is associated with increased cardiovascular morbidity and mortality, with stroke being an especially important and potentially devastating complication. The number of patients with atrial fibrillation is likely to increase 2.5-fold during the next 50 years, reflecting the growing proportion of elderly individuals. Emergency departments play a central role in diagnosis and treatment (rhythm and rate control, initiation of anticoagulatory therapy for stroke prevention) of atrial fibrillation. Additionally, embolic (e.g. stroke, mesenteric ischemia) complications of atrial fibrillation and bleeding complications (e.g. gastrointestinal and intracranial) of anticoagulatory therapy are likewise treated at emergency departments.

Therefor the investigators hypothesis implies that the atrial fibrillation registry could serve as a tool for structured diagnosis and therapy in patients with atrial fibrillation and therefore may improve patient care. Additionally, diagnostic and therapeutic shortcomings by analyzing registry data may be detected.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Oct 2014 (actual). Primary completion is estimated for Jan 2020, 62 months after the start.

Of 550 non-industry observational studies under Atrial Fibrillation, half reached primary completion within 46 months of starting (the median), counting those still running; a quarter within 25 and three quarters within 91. This study's planned 62 months is above that.

Counting every sponsor, half of 698 studies reached it within 38 months; a quarter within 22 and three quarters within 76.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 5, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
