Insights
Low prognostic nutritional index (PNI) and high visceral adiposity index (VAI) are risk factors for postoperative atrial fibrillation (PoAF) after coronary artery bypass grafting (CABG). These simple markers can help predict PoAF risk in patients undergoing CABG surgery.
Area of Science:
- Cardiology
- Surgical Complications
- Biomarkers
Background:
- Postoperative atrial fibrillation (PoAF) is a common complication after coronary artery bypass grafting (CABG), affecting up to 50% of patients.
- Predicting PoAF is crucial for patient management and improving outcomes following cardiac surgery.
Purpose of the Study:
- To investigate the predictive value of prognostic nutritional index (PNI) and visceral adiposity index (VAI) for PoAF in patients undergoing CABG with cardiopulmonary bypass.
- To identify simple, readily available markers for PoAF risk stratification.
Main Methods:
- Prospective study including 199 patients who underwent isolated CABG with cardiopulmonary bypass.
- Patients were divided into two groups: those who did not develop PoAF (Group 1) and those who did (Group 2).
- Multivariate analysis was used to identify independent predictors of PoAF.
Main Results:
- PoAF occurred in 55 patients (27.6%).
- Independent predictors for PoAF included older age, chronic obstructive pulmonary disease, and lower PNI (Model 1).
- Older age, lower lymphocyte counts, and higher VAI were also identified as independent predictors of PoAF (Model 2).
Conclusions:
- Low PNI and high VAI are significant risk factors for PoAF after CABG.
- PNI and VAI are valuable, easily calculable parameters for predicting PoAF risk in patients undergoing CABG.
Introduction:
Rhythm problems are the most observed complications following coronary artery bypass grafting (CABG), the most common being postoperative atrial fibrillation (PoAF), with an incidence reaching 50% of the patients. In this study, we aimed to investigate the predictive importance of prognostic nutritional index (PNI) and visceral adiposity index (VAI) in predicting PoAF, which occurs after CABG accompanied by cardiopulmonary bypass.
Methods:
Patients who underwent isolated CABG with cardiopulmonary bypass between June 15 and October 15, 2019, were prospectively included in the study. Patients who did not develop in-hospital PoAF were identified as Group 1, and those who did constituted Group 2.
Results:
PoAF developed in 55 (27.6%) patients (Group 2). The mean age of the 144 patients included in Group 1 and 55 patients in Group 2 were 56.9±8.7 and 64.3±10.2 years, respectively (P<0.001). In multivariate analysis Model 1, age (odds ratio [OR]: 1.084, confidence interval [CI]: 1.010-1.176, P=0.009), chronic obstructive pulmonary disease (OR: 0.798, CI: 0.664-0.928, P=0.048), and PNI (OR: 1.052, CI: 1.015-1.379, P=0.011) were determined as independent predictors for PoAF. In Model 2, age (OR: 1.078, CI: 1.008-1.194, P=0.012), lymphocyte counts (OR: 0.412, CI: 0.374-0.778, P=0.032), and VAI (OR: 1.516, CI: 1.314-2.154, P<0.001) were determined as independent predictors for PoAF.
Conclusion:
In this study, we determined that low PNI, a simply calculable and cheap parameter, along with high VAI were risk factors for PoAF.
