摘要:

目的 分析持续性心房颤动(房颤)患者的血清组蛋白去乙酰化酶3(HDAC3)、赖氨酰氧化酶样蛋白2(LOXL2)水平对其射频消融术后1年房颤复发的预测价值。方法 选择持续性房颤患者200例作为疾病组,同期同年龄段的健康体检者132例作为健康组。采用酶联免疫吸附测定试验检测2组的血清HDAC3、LOXL2水平,并收集其他临床指标。根据术后1年内是否复发房颤,将疾病组又分成未复发组(125例)与复发组(75例)。使用多因素Logistic回归模型分析影响房颤患者1年复发的因素;采用受试者工作特征(ROC)曲线分析血清HDAC3、LOXL2水平对房颤患者1年复发的预测价值。结果 疾病组患者术后血清HDAC3、LOXL2水平明显低于其术前水平(P<0.05);复发组患者HDAC3、LOXL2水平高于未复发组(P<0.05);HDAC3、LOXL2水平高是影响患者房颤复发的危险因素(P<0.05),二者单独与联合预测房颤复发的曲线下面积(AUC)分别为0.833(95%CI:0.774~0.882)、0.829(95%CI:0.770~0.879)以及0.907(95%CI:0.858~0.943),联合预测优于单独预测(Z二者联合-HDAC3=3.384、Z二者联合-LOXL2=3.438,均P<0.05)。结论 血清HDAC3、LOXL2水平升高是影响房颤患者复发的因素,其对射频消融术后1年患者的房颤复发具有较好的预测价值。

Abstract:

Objective To analyze the predictive value of serum histone deacetylase 3 (HDAC3) and lysyl oxidase like protein 2 (LOXL2) levels in patients with persistent atrial fibrillation for artial fibrillation recurrence one year after radiofrequency ablation. Methods A total of 200 patients with persistent atrial fibrillation treated in our hospital were served as the disease group, and 132 healthy individuals of the same age during the same period were selected as the healthy group. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of serum HDAC3 and LOXL2 before and after surgery in the two groups, and other relevant clinical indicators were collected. Patients were assigned into the non recurrence group (125 cases) and the recurrence group (75 cases) based on their recurrence status within one year. Multivariate Logistic regression model was used to analyze factors influencing the recurrence within one year in patients of the disease group. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of serum HDAC3 and LOXL2 levels for recurrence of atrial fibrillation in patients within one year. Results The postoperative serum HDAC3 and LOXL2 levels were prominently lower in the disease group than those before surgery (P<0.05). The serum levels of HDAC3 and LOXL2 were higher in the recurrence group than those in the non-recurrence group (P<0.05). The high levels of HDAC3 and LOXL2 were risk factors affecting the recurrence of atrial fibrillation in patients (P<0.05). The area under the curve (AUC) values of serum HDAC3 and LOXL2 alone and their combination for predicting recurrence of atrial fibrillation in patients in the disease group were 0.833 (95%CI: 0.774-0.882), 0.829 (95%CI: 0.770-0.879) and 0.907 (95%CI: 0.858-0.943), respectively. The combined prediction was superior to the individual predictions (Zcombination-HDAC3=3.384, Zcombination-LOXL2=3.438, P<0.05). Conclusion The elevated serum levels of HDAC3 and LOXL2 are factors influencing the recurrence of atrial fibrillation in patients, and both are predictive factors that affect recurrence of atrial fibrillation in patients one year after radiofrequency ablation.
