摘要:

目的 探讨心电图右束支传导阻滞(RBBB)联合血清高迁移率族蛋白B1(HMGB1)在慢性阻塞性肺疾病(COPD)患者并发肺心病中的临床应用价值。方法 纳入138例COPD患者,随访12个月,根据是否发生肺心病分为肺心病组(42例)和无肺心病组(96例)。比较2组基线特征、RBBB阳性率和HMGB1水平差异,采用Cox回归分析RBBB、HMGB1与肺心病发病的关联强度,受试者工作特征(ROC)曲线评价二者的预测效能,Kaplan-Meier法分析COPD患者肺心病的进展情况。结果 肺心病组RBBB阳性率(59.5% vs. 22.9%)及血清HMGB1水平[(8.92±2.61)μg/L vs.(5.38±1.77)μg/L]高于无肺心病组(均P<0.01)。RBBB联合HMGB1预测肺心病发病的曲线下面积(AUC)为0.915(95%CI:0.856~0.962),高于单一指标预测。多因素Cox回归结果显示,在校正多个混杂因素后,RBBB阳性(HR=2.002,95%CI:1.289~3.107,P<0.001)和HMGB1升高(HR=1.177,95%CI:1.063~1.303,P=0.002)仍是COPD患者肺心病发病的独立危险因素。Kaplan-Meier分析显示,高风险组(RBBB阳性且HMGB1≥6.85 μg/L)患者1年并发肺心病发生率为63.64%,显著高于低风险组(RBBB阴性且HMGB1<6.85 μg/L)患者(8.82%,Log-rank χ2=50.465,P<0.001)。结论 RBBB联合血清HMGB1有助于评估COPD患者并发肺心病的风险,可识别高危人群。

Abstract:

Objective To investigate the clinical value of electrocardiographic right bundle branch block (RBBB) combined with serum high-mobility group box 1 (HMGB1) in monitoring the development of cor pulmonale in patients with chronic obstructive pulmonary disease (COPD). Methods A total of 138 COPD patients were enrolled and followed up for 12 months. Patients were divided into the cor pulmonale group (n=42) and the non-cor pulmonale group (n=96) based on whether cor pulmonale occurred during follow-up. Baseline characteristics, RBBB positivity rates and serum HMGB1 levels were compared between the two groups. Multivariate Cox regression was used to assess the association between RBBB, HMGB1 and cor pulmonale development. Receiver operating characteristic (ROC) curves were constructed to evaluate the predictive performance of each indicator, and the Kaplan-Meier method was applied to analyze the progression of cor pulmonale in COPD patients. Results The positive rate of RBBB (59.5% vs. 22.9%) and serum HMGB1 levels [(8.92±2.61) μg/L vs. (5.38±1.77) μg/L)] were significantly higher in the cor pulmonale group than those in the non-cor pulmonale group ( P<0.01). The area under the curve (AUC) for RBBB combined with HMGB1 in predicting cor pulmonale was 0.915 (95%CI: 0.856-0.962), which was superior to either marker alone. Multivariate Cox regression analysis demonstrated that after adjusting for multiple confounding factors, RBBB positivity (HR=2.002, 95%CI: 1.289-3.107, P<0.001) and elevated HMGB1 (HR=1.177, 95%CI: 1.063-1.303, P=0.002) remained independent risk factors for cor pulmonale in COPD patients. Kaplan-Meier analysis revealed that the 1-year incidence of cor pulmonale was 63.64% in the high-risk group (RBBB-positive and HMGB1 ≥6.85 μg/L), which was significantly higher than that in the low-risk group (RBBB-negative and HMGB1<6.85 μg/L) (8.82%, Log-rank χ2=50.465, P<0.001). Conclusion The combination of RBBB and serum HMGB1 provides valuable clinical utility in assessing the risk of cor pulmonale in COPD patients and enables effective identification of high-risk individuals.
