Background and purpose Post-operative AF (POAF) is considered a phenomenon rather than a definite diagnosis and the current clinical guidelines have no specific recommendations regarding its management. Few prospective studies have been performed in non-cardiac conditions and consequences of POAF in patients without known heart disease is not well described. However, recent data suggest an association between POAF in relation to non-cardiac surgery and increased post-operative mortality and stroke. POAF in relation to abdominal surgery seems common (incidence: 8-18%); however, the true incidence is uncertain. The available studies are few, heterogenous and often methodologically inadequate. The study aims at reporting the true incidence of AF, and associated complications, in relation to abdominal surgery.
Material and methods Designed as a prospective, single-centre, cohort study of consecutive adult patients undergoing acute or elective abdominal surgery at Department of Abdominal Surgery at Bispebjerg Hospital. Patients who are pregnant or where follow-up is not possible will be excluded. Patients will be examined pre-operatively by ECG and signal processed surface ECG (wavECG). Heart rhythm monitoring will be worn from admission and until discharge (preferably ≥72 hour post-operatively). Examinations are repeated 90 days post-operatively. Additional follow-up will be based on patient charts for ≥12 months. Primary endpoint is occurrence/recurrence of AF. The study will include 300 patients.
Perspective If more thorough heart rhythm monitoring of patients undergoing abdominal surgery leads to identification of more patients with AF, routine continuous heart rhythm monitoring should be considered recommended in upcoming guidelines to prevent associated complications.
