NCT03130985

Brief Summary

Patients undergoing coronary artery bypass grafting (CABG), aortic (valve) or mitral valve surgery are at risk of developing postoperative and new-onset atrial fibrillation (AF), but adequate risk prediction is currently impossible. This study aims to discover tissue and circulating microRNAs and protein biomarkers that may help to unravel the pathophysiological processes underlying AF and are potential tools for risk stratification and prognosis or may become future targets of therapy. This study will be a single-center cohort study of 150 patients undergoing cardiac surgery, which will constitute the beginning of the follow-up period. Left atrial appendages, whole blood and epicardial mappings will be collected. Patients will be followed for 2 years with regular holter investigations to detect postoperative and new-onset AF.

Outcome Measures

Primary Outcomes (2)

  • incident Atrial Fibrillation

    A de novo 30 second continuous rhythm registration of AF, or an ECG recording of an AF episode within 2 years after surgery (with a blanking period for the postoperative period \<30 days).

    within 2 years after surgery

  • Postoperative Atrial Fibrillation

    A 30 second continuous rhythm registration of AF, or an ECG recording of an AF episode in the first 30 days following cardiac surgery or registered at the first 24h Holter monitoring if scheduled within 6 weeks following cardiac surgery.

    within the first 30 days after surgery

Secondary Outcomes (1)

  • Quality of Life defined by 36-Item Short Form Health Survey questionnaire

    at 6 months and 1 year follow-up

Study Arms (1)

Cardiac surgery patients

The study cohort will comprise of patients without a history of AF that undergo cardiac surgery (CABG or mitral valve surgery) with increased CHADSVASC scores of ≥2.

You may not qualify if:

  • Unable or unwilling to comply with study procedures
  • Documented or reported history of atrial fibrillation, atrial flutter (duration \> 5 minutes) or ventricular tachycardia
  • Emergency or redo of CABG
  • Emergency valvular surgery or pericarditis or endocarditis
  • NYHA class IV heart failure symptoms or left ventricular ejection fraction \< 35%
  • Pregnancy or of childbearing potential without adequate contraception
  • History of previous radiation therapy of the thorax
  • Active malignancy
  • Active inflammtion or auto-immune disease
  • Surgery for congenital anomalies
  • Circumstances that prevent follow-up (no permanent home or address, transient, etc.)
