Heart rhythm registry aims to uncover hidden risks in AF patients

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Retrospective Part The retrospective part will include patients who attended a physician consultation for atrial fibrillation three years ago and who met the inclusion criteria at that time. Inclusion criteria for the retrospective part: * Male or female patients aged 18 to 64 years at the time of data registration; * Presence of a specialist-confirmed diagnosis of atrial fibrillation; * CHA₂DS₂-VASc score ranging from 0 to 2 for men and from 1 to 3 for women. Non-inclusion criteria for the retrospective part: * Age under 18 years; * Age over 64 years; * CHA₂DS₂-VASc score greater than 2 for men and greater than 3 for women; * Inability to undergo screening examination and follow-up; * 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. Prospective Part Inclusion criteria for the prospective part: * Male or female patients aged 18 to 64 years at the time of data registration; * Presence of a specialist-confirmed diagnosis of atrial fibrillation; * CHA₂DS₂-VASc score ranging from 0 to 2 for men and from 1 to 3 for women at the time of screening. Non-inclusion criteria for the prospective part: * Age under 18 years; * Age over 64 years; * CHA₂DS₂-VASc score greater than 2 for men and greater than 3 for women; * Inability to undergo screening examination and follow-up; * 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).
