Predictive value of NT-proBNP, procalcitonin and CVP in patients with new-onset postoperative atrial fibrillation after cardiac surgery.

To investigate the predictive value of N-terminal pro brain natriuretic peptide (NT-proBNP), procalcitonin and central venous pressure (CVP) for new atrial fibrillation after cardiac surgery.Patients underwent cardiac surgery in Huai'an First People's Hospital from June 2019 to December 2020 were enrolled in this study. Patients without POAF after surgery were included in the control group, and patients with POAF after surgery were included in the POAF group. Clinical data of patients were collected and retrospectively analyzed.The incidence of in-hospital complications, length of stay and cost of hospitalization in the POAF group were significantly higher than those in the control group; Moreover, there were significant differences in central venous pressure, peak cTnI, NT-proBNP, procalcitonin, and white blood cell counts between the two groups. NT-proBNP, procalcitonin and elevated central venous pressure are independent risk factors for POAF in patients after cardiac surgery.NT-proBNP, procalcitonin and CVP were closely related with atrial fibrillation after cardiac surgery. The combination of NT-proBNP, procalcitonin and CVP had a better discriminative ability for new atrial fibrillation after cardiac surgery compared to either of them alone.
