N-terminal pro-brain natriuretic peptide as a predictor of postoperative atrial fibrillation in off-pump coronary artery bypass grafting patients.
Postoperative atrial fibrillation (POAF) is a common complication following off-pump coronary artery bypass grafting (CABG). This study aims to assess whether elevated preoperative N-terminal pro-brain natriuretic peptide (NT-proBNP) levels can effectively stratify patients based on their risk of developing POAF.
Utilizing a retrospective database of 512 patients who underwent off-pump CABG, we compared preoperative clinical data, including NT-proBNP levels, between patients experiencing POAF lasting longer than 30 s during hospitalization and those who did not.
POAF manifested in 23.6% of patients (121 out of 512). After off-pump CABG, 39% of patients (100 out of 256) with NT-proBNP levels greater than the median (388 pg/mL) developed POAF, in contrast to only 8% of patients (21 out of 256) with levels below 388 pg/mL (P < 0.0001). NT-proBNP levels were significantly higher in patients with POAF compared to those without (median, 1149 vs. 278 pg/mL; P < 0.0001). Multivariate logistic regression analysis revealed that in patients undergoing off-pump CABG, a NT-proBNP level of 388 pg/mL or greater (OR, 5.72; 95% CI, 3.24-10.48; P < 0.0001) was the only independent risk factor for POAF.
For patients undergoing off-pump CABG, increased age, preoperative left ventricular ejection fraction (LVEF) and left atrial diameter (LAD), creatinine levels, and a preoperative NT-proBNP level of 388 pg/mL or greater emerged as significant risk factors for POAF. Identifying individuals predisposed to POAF enables the design of trials evaluating preventive strategies to mitigate this complication.
