Detaljeret beskrivelse

This is a prospective registry study with data being collected continuously for 24 months.

Patients who have electrocardiographically confirmed atrial fibrillation, are being followed by the Pen Bay Medical Center Anticoagulation Services and are at least 90 years old will be recruited into the study. A matched cohort of patients between the ages of 80 and 89 and another matched cohort of patients between the ages of 70 and 79 will also be recruited into the study for comparison.

Data related to adverse events, concomitant medications, living arrangements, mobility and alcohol use will be collected every 6 months. In addition the CHA2DS2-VASc (score for atrial fibrillation stroke risk), HAS - BLED (major bleeding risk score for patients on anticoagulation), frailty and Mini Cog scores will be recalculated at each visit.
