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.
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.
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.
In this study, we determined that low PNI, a simply calculable and cheap parameter, along with high VAI were risk factors for PoAF.
节律问题是冠状动脉旁路移植术后（CABG）最常见的并发症，最常见的是术后心房颤动（PoAF），发生率达到患者的 50%。在这项研究中，我们旨在研究预后营养指数（PNI）和内脏脂肪指数（VAI）在预测 CABG 术后合并体外循环后发生的 PoAF 中的预测重要性。
2019 年 6 月 15 日至 10 月 15 日期间，前瞻性纳入接受单纯 CABG 加体外循环的患者。未发生院内 PoAF 的患者为第 1 组，发生 PoAF 的患者为第 2 组。
55 例（27.6%）患者发生 PoAF（第 2 组）。第 1 组 144 例患者和第 2 组 55 例患者的平均年龄分别为 56.9±8.7 岁和 64.3±10.2 岁（P<0.001）。多变量分析模型 1 中，年龄（比值比[OR]：1.084，95%置信区间[CI]：1.010-1.176，P=0.009）、慢性阻塞性肺疾病（OR：0.798，CI：0.664-0.928，P=0.048）和 PNI（OR：1.052，CI：1.015-1.379，P=0.011）被确定为 PoAF 的独立预测因子。在模型 2 中，年龄（OR：1.078，CI：1.008-1.194，P=0.012）、淋巴细胞计数（OR：0.412，CI：0.374-0.778，P=0.032）和 VAI（OR：1.516，CI：1.314-2.154，P<0.001）被确定为 PoAF 的独立预测因子。
在这项研究中，我们确定了低 PNI，这是一个简单计算且廉价的参数，以及高 VAI 是 PoAF 的危险因素。
