New-onset atrial fibrillation (NOAF) is a common complication in patients with acute myocardial infarction (AMI) during hospitalization. Galectin-3 (Gal-3) is a novel inflammation marker that is significantly associated with AF. The association between post-AMI NOAF and Gal-3 during hospitalization is yet unclear.
The present study aimed to investigate the predictive value of plasma Gal-3 for post-AMI NOAF.
A total of 217 consecutive patients admitted with AMI were included in this retrospective study. Peripheral venous blood samples were obtained within 24 h after admission and plasma Gal-3 concentrations were measured.
Post-AMI NOAF occurred in 18 patients in this study. Patients with NOAF were older (p < 0.001) than those without. A higher level of the peak brain natriuretic peptide (BNP) (p < 0.001) and Gal-3 (p < 0.001) and a lower low-density lipoprotein cholesterol level (LDL-C) (p = 0.030), and an estimated glomerular filtration rate (e-GFR) (p = 0.030) were recorded in patients with post-AMI NOAF. Echocardiographic information revealed that patients with NOAF had a significantly decreased left ventricular eject fraction (LVEF) (p < 0.001) and an increased left atrial diameter (LAD) (p = 0.004) than those without NOAF. The receiver operating characteristic (ROC) curve analysis revealed a significantly higher value of plasma Gal-3 in the diagnosis of NOAF for patients with AMI during hospitalization (area under the curve (p < 0.001), with a sensitivity of 72.22% and a specificity of 72.22%, respectively. Multivariate logistic regression model analysis indicated that age (p = 0.045), plasma Gal-3 (p = 0.018), and LAD (p = 0.014) were independent predictors of post-MI NOAF.

新发心房颤动（NOAF）是住院期间急性心肌梗死（AMI）患者的常见并发症。半乳糖凝集素-3（Gal-3）是一种新型炎症标志物，与 AF 显著相关。AMI 后住院期间发生的 NOAF 与 Gal-3 之间的关系尚不清楚。
本研究旨在探讨血浆 Gal-3 对 AMI 后 NOAF 的预测价值。
本回顾性研究共纳入 217 例连续入院的 AMI 患者。入院后 24 小时内采集外周静脉血样，测量血浆 Gal-3 浓度。
本研究中有 18 例患者发生 AMI 后 NOAF。NOAF 组患者年龄大于无 NOAF 组（p<0.001）。NOAF 组患者的峰值脑钠肽（BNP）（p<0.001）和 Gal-3（p<0.001）水平较高，低密度脂蛋白胆固醇（LDL-C）（p=0.030）和估算肾小球滤过率（e-GFR）（p=0.030）水平较低。超声心动图信息显示，NOAF 组患者的左心室射血分数（LVEF）明显降低（p<0.001），左心房内径（LAD）增大（p=0.004）。受试者工作特征（ROC）曲线分析显示，住院期间 AMI 患者的血浆 Gal-3 值对诊断 NOAF 具有更高的价值（曲线下面积（p<0.001），其灵敏度为 72.22%，特异性为 72.22%。多变量 logistic 回归模型分析表明，年龄（p=0.045）、血浆 Gal-3（p=0.018）和 LAD（p=0.014）是 AMI 后发生 NOAF 的独立预测因素。
