Health Consequences of the Burden of Atrial Fibrillation

Health Consequences of the Burden of Atrial Fibrillation - The Swiss-AF-BURDEN Study

The Swiss-AF-BURDEN study will be embedded in the follow-up visits of the Swiss-AF cohort study. The research question of the current atrial fibrillation burden will be answered by using 7-day Holter-ECG recordings and continuous implanted loop recorder recording, whereas cardiac MRI examination will give results about cardiac dimensions and function. The 7-day Holter ECG will be repeated after one year. The cMRI will be performed separately or directly after the brain MRI to minimize the additional burden for the patients. Only a subsample of 100 patients will additionally receive ILR for 2 years.

Inclusion Criteria:

• Swiss-AF study patient
• Paroxysmal or persistent AF

Exclusion Criteria:

• Permanent AF
• Swiss-AF patients not willing or able to undergo 7-day Holter monitoring
• Specifically for cMRI: Pregnant women or women of child-bearing age without a prior negative pregnancy test
