Postoperative new-onset atrial fibrillation (PNAF) is a common complication after cardiac surgery, affecting up to 60% of patients. PNAF has been associated with a higher incidence of adverse postoperative outcomes including long-term mortality, and leads to an increased use of resources and higher social costs.
Many studies have investigated potential determinants of PNAF. Established determinants can grossly be divided into inflammatory factors, cardiac functional (echographic) parameters, cardiac electrophysiologic properties and other (demographic) risk factors. Also, a substantial number of studies have investigated pharmacological prophylactic strategies. In these studies, the highest effectiveness has been shown for strategies involving either betablockers, statins and, more recently, corticosteroids.
The DExamethasone for Cardiac Surgery - Postoperative New-onset Atrial Fibrillation (DECS-PNAF) project described in this protocol aims to elucidate how corticosteroids protect cardiac surgical patients from PNAF. The modulating effect of intraoperative prophylactic high-dose dexamethasone administration on the categories of perioperative determinants of PNAF mentioned above will be studied in 164 coronary artery bypass grafting surgery patients. For this, multiple perioperative assessments will be performed using, for example, repeated biochemical assessment of inflammation, genomic analysis of (mainly inflammatory) single nucleotide polymorphisms, continuous electrocardiographic (Holter) monitoring and transesophageal echocardiography.
The DECS-PNAF project is one of the first prospective studies to combine a detailed assessment of multiple categories of PNAF determinants. Moreover, it is unique in studying the effect of prophylactic corticosteroid administration on every one of these determinants.
