Summary

Purpose The primary purpose of the current project is to characterize unselected patients undergoing surgery developing post-operative atrial fibrillation (POAF), ultimately leading to a new risk-stratification model.

Background and rationale According to rather scarce existing reports, it is estimated that 10% will develop POAF following abdominal surgery. It remains a challenge for the clinicians to predict which patients are at risk. POAF can be difficult to diagnose, as symptoms are often vague. Hence, the diagnosis may remain underreported leaving many patients without adequate treatment. Untreated atrial fibrillation is associated with increased morbidity and mortality, especially due to an increased risk of ischemic stroke.

Methods Three-hundred adult patients admitted for surgery at the Digestive Disease Center at Bispebjerg Hospital will be examined by heart rhythm monitoring during hospitalization, i.e. pre-, peri- and postoperatively in the main SECAFIB-SURG study. Twenty study participants who develop POAF and 20 without POAF matched with these on sex, age and co-morbidity, will undergo additional cardiovascular examinations three months after surgery in the current sub-study. All patients will be followed for at least one year after surgery. The study is scheduled for completion within two years, commencing in January 2020.

Perspective Creating a POAF risk-stratification model for patients undergoing abdominal surgery, could ensure timely diagnosis and treatment, hence, preventing complications associated with POAF.
