Study summary

Multicenter Non-Interventional Real-World Clinical Practice Registry of Patients with Atrial Fibrillation. The primary objective of the registry is an epidemiological assessment of the characteristics, clinical outcomes, and therapeutic approaches in patients with atrial fibrillation and a CHA₂DS₂-VASc score of no more than 2 for men and no more than 3 for women.

Read the detailed description

Multicenter Non-Interventional Real-World Clinical Practice Registry of Patients with Atrial Fibrillation. The primary objective of the registry is an epidemiological assessment of the characteristics, clinical outcomes, and therapeutic approaches in patients with atrial fibrillation and a CHA₂DS₂-VASc score of no more than 2 for men and no more than 3 for women.

The registry comprises both a retrospective and a prospective component. Patient enrollment in the retrospective part will be conducted through the review of medical records of individuals who were followed up for atrial fibrillation at the participating centers during the preceding three years. For inclusion in the prospective part, screening of all patients meeting the predefined inclusion and non-inclusion criteria will be performed during routine outpatient and inpatient care, followed by prospective follow-up over a three-year period.

Data derived from the retrospective and prospective phases of the registry will enable an epidemiological assessment of the demographic and clinical characteristics, outcomes, and therapeutic approaches employed in real-world clinical practice among patients with atrial fibrillation. These findings may provide important insights to advance the understanding of diagnostic and management strategies, and to inform efforts aimed at optimizing healthcare delivery within this patient cohort.

  • Organ or tissue transplantation less than 5 years prior to study enrollment;
  • Open heart surgery (coronary artery bypass grafting, valve replacement, reconstructive aortic surgery) within 6 months prior to study enrollment;
  • Established diagnosis of dementia of any severity and/or established diagnosis of moderate or severe encephalopathy, as well as other conditions precluding independent regular medication intake.

Exclusion criteria:

  • Patient withdrawal of consent for further participation in the study;
  • Identification of factors precluding further patient participation in the study (at the physician's discretion).
