Sponsored by Khon Kaen University · Observational
This multicenter observational study aims to investigate the incidence and identify risk factors associated with postoperative atrial fibrillation (POAF) in patients undergoing cardiac surgery at three medical centers in Thailand. The study will examine patient characteristics, surgical factors, and anesthetic management practices that may contribute to the development of this common postoperative complication.
Postoperative atrial fibrillation (POAF) is a common complication following cardiac surgery, with incidence rates reported between 15-30% after valve surgery and 18-74% after coronary artery bypass grafting. POAF typically occurs within 72 hours after surgery and is associated with increased morbidity, mortality, length of hospital stay, and healthcare costs.
The Society of Thoracic Surgeons has identified five major postoperative complications associated with cardiac surgery, including POAF, which can significantly affect patient outcomes. This multicenter observational study will examine the incidence and risk factors of POAF in cardiac surgery patients across three medical centers in Thailand: Srinagarind Hospital at Khon Kaen University, Northeastern Thailand Cardiac Center, and Surat Thani Hospital.
The study will collect data on patient demographics, comorbidities, preoperative laboratory values, perioperative characteristics, surgical procedures (valve surgery, CABG, combined procedures), and postoperative complications. By identifying risk factors associated with POAF, this study aims to develop preventive strategies and improve management protocols for patients at high risk for this complication.
