The risk factors of postoperative atrial fibrillation in critically ill lung surgery patients and the establishment of nomogram / 中华胸心血管外科杂志

ABSTRACT

Objective:To identify the risk factors of postoperative atrial fibrillation (POAF) in critically ill lung surgery patients and establish a nomogram.Methods:213 critically ill lung surgery patients were collected in Beijing Chaoyang Hospital from January 2018 to December 2021. Logistic analysis was used to analyze the risk factors of POAF. A nomogram was developed based on the verified risk factors. Results:The independent risk factors associated with POAF was mitral regurgitation ( OR=4.270, 95% CI 1.380-13.213, P=0.012), cedilanid ( OR=14.619, 95% CI 2.913-73.373, P=0.001), catecholamine ( OR=3.244, 95% CI 1.144-9.203, P=0.027), pericardiotomy( OR=6.079, 95% CI 1.362-27.128, P=0.009), systematic lymph node dissection( OR=5.460, 95% CI 1.770-16.846, P=0.003). Nomogram model showed the ROC was 0.801(95% CI 0.721-0.881, P<0.001). Conclusion:The risk factors of POAF in critically ill lung surgery patients are mitral regurgitation, cedilanid, catecholamine, pericardiotomy and systematic lymph node dissection. The nomogram predicted POAF better than other scoring systems.
