Brief Summary

A. Compare the plasmatic biomarkers between the cohort with and without AFib. B. Find sensitive and specific biomarkers that could be used for the diagnostic management of AFib. C. Compare the quality of sleep between the cohort with and without AFib by the means of sleeping quality questionnaire

Outcome Measures

Primary Outcomes (2)

  • Plasmatic biomarkers

    Compare the plasmatic biomarkers between the cohort with and without atrial fibrillation: 1. Coagulation a D - dimer b Fibrinogen 2. Inflammation and fibrosis a Hs - CRP b AGEs c Soluble RAGE 3. Hemodynamics (LA stretch) a Apelin b NT - proBNP c Hs - troponin 4. MicroRNA a miRNA - 1 b miRNA - 19 c miRNA - 21 d miRNA - 124 e miRNA - 150 f miRNA - 328

    Day of inclusion

  • Quality of sleep

    Compare the quality of sleep between the cohort with and without atrial fibrillation by the means of Athens Insomnia Scale (AIS). It is measured by assessing eight factors amongst which first five factors are related to nocturnal sleep and last three factors are related to daytime dysfunction. These are rated on a 0-3 scale and the sleep is finally evaluated from the cumulative score of all factors and reported as an individual's sleep outcome. A cut-off score of ≥6 on the AIS is used to establish the diagnosis of insomnia.

Study Arms (2)

Study group

Adult patients with documented paroxysmal, nonvalvular atrial fibrillation with CHA2DS2-VASc score \> 2 (for females \> 3) and sinus rhythm at the time of inclusion. In total 100 patients will be included.

Diagnostic Test: ECHOcardiographyDiagnostic Test: Peripheral blood samples for plasmatic biomarkersDiagnostic Test: Athens insomnia scale questionnaire

Control group

Patients without a history of palpitations or irregular heart rhythm. AFib will be excluded with the help of 7 days ECG Holter and ECG event recorder monitoring. In total 100 patients will be included. Propensity matching according to the: * CHA2DS2-VASc parameters * LVEF: preserved (\<40%), mid-range (40-49%) and reduced (\>50%) * Presence of diastolic dysfunction * Glomerular filtration rate: (≥1,5 ml/s), (1,4-1 ml/s) and (0,9-0,5 ml/s) * Drugs: ACE-I/ARB, betablockers, digoxin, amiodarone * BMI: (\<30kg/m2), (30-39kg/m2) and (≥40kg/m2) * Smoking (\>5 cigarettes per day)
