Fibrosis, Inflammation and Brain Health in Atrial Fibrillation. (NOR-FIB2)
Fibrosis, Inflammation and Brain Health in Atrial Fibrillation. The Norwegian Atrial Fibrillation and Stroke Study
Protocol synopsis Sponsor: Oslo University Hospital Title: Fibrosis, inflammation and cerebral infarction in patients with atrial fibrillation Study Design: The study is an observational prospective study of atrial fibrillation patients undergoing direct-current cardioversion.
Primary Objective: To assess the prevalence and causes of new silent cerebral ischemic lesions after programmed direct-current cardioversion using diffusion-weighted sequences in brain MRI (DWMRI).
Secondary Objectives:
To study the impact of inflammation measured by biomarkers and cardiac 18F-FDG-PET on the risk for new silent cerebral ischemic lesions after direct-current cardioversion for AF.
To assess the impact of fibrosis measured by biomarkers on the risk for new silent cerebral ischemic lesions after direct-current cardioversion for AF.
To assess cognitive and cerebral structural and metabolic changes after direct-current cardioversion for AF using cognitive assessments and cerebral and cardiac 18F-FDG-PET before and 12 months after treatment.
Number of Subjects: 50
Study Centers: Østfold Hospital Trust
Duration of Study Participation:
- Enrollment: 18 months
- Follow-up period: 12 months
- Total Study Duration: 30 months
Primary Endpoints:
• Number of new small cerebral infarcts detected with DWMRI two weeks after direct current cardioversion.
Secondary Endpoints:
- Rate of AF recurrence within 1 year after direct current cardioversion
- Change in levels of inflammation biomarkersfrom baseline to 12 months follow-up
- Change in levels of fibrosis biomarkers from baseline to 12 months follow-up
- Cognitive function at 12 months follow-up
- Changes in uptake pattern on cerebral 18F-FDG-PET from baseline to 12 months follow-up
- Changes in uptake pattern on cardiac 18F-FDG-PET from baseline to 12 months follow-up
- Brain volume at 12 months follow-up
- White matter volume 12 months follow-up
- Grey matter volume 12 months follow-up
- Cortical volume 12 months follow-up
- RSI-derived diffusion parameters 12 months follow-up: fast apparent diffusion coefficient, extracellular water fraction, fractional anisotropy; free water fraction; intracranial volume; NAWM: normal appearing white matter; neurite density; RSI: restriction spectrum imaging; sADC: slow apparent diffusion coefficient;restricted fractional anisotropy; white matter lesions.
