摘要:
目的 肝硬化性心肌病(CCM)是肝硬化引起的心脏功能障碍和电生理紊乱,与肝硬化患者预后密切相关。血管内皮细胞特异性分子1(endocan)作为心血管疾病的诊断指标,是否参与CCM发病机制尚不明确。本研究拟检测CCM患者血清endocan的表达量及其与CCM的关系,推测在CCM发病中的可能作用。 方法 本研究为横断面研究,连续入组2019年1月—2021年1月首都医科大学附属北京佑安医院住院的肝硬化患者,根据有无CCM,分为CCM组(n=19)和无CCM组(n=106)。采用ELISA方法检测不同组血清endocan水平以及与肝功能、心脏功能的相关性。正态分布的计量资料两组间比较采用成组t检验,偏态分布的计量资料两组间比较采用Mann-Whitney U秩和检验。计数资料组间比较采用χ2检验。采用Pearson或Spearman相关分析进行相关性检验,应用受试者工作特征曲线(ROC曲线)评价CCM预测模型。 结果 CCM组患者血清endocan的表达量为[(2.69±0.43)ng/mL]明显高于无CCM组[(2.23±0.52)ng/mL](t=2.247,P=0.034)。在代偿期肝硬化患者血清endocan表达量[(2.41±0.37)ng/mL]显著低于失代偿期肝硬化组[(2.72±0.49)ng/mL](t=3.214,P=0.02)。CCM组患者血清endocan水平与肝功能Child-Pugh评分(r=0.509,P=0.026)、MELD-Na评分(r=0.484,P=0.036)呈正相关,与平均动脉压(r=-0.591,P=0.013)、二尖瓣舒张早期血流早峰值E波和舒张晚期血流峰值A波(E/A)比值(r=-0.515,P=0.042)呈负相关。血清endocan预测CCM的ROC曲线下面积为0.658(95%CI:0.522~0.781),当截断值为2.61 ng/mL时,敏感度为67.1%,特异度为73.7%。 结论 血清endocan与CCM的发生具有一定相关性,可能参与了CCM的发病机制。 -

Abstract:Objective Cirrhotic cardiomyopathy (CCM) refers to cardiac dysfunction and electrophysiological disorder caused by liver cirrhosis and is closely associated with the prognosis of patients with liver cirrhosis. Endothelial cell-specific molecule 1 (endocan) can be used as a diagnostic marker for cardiovascular diseases, and it remains unclear whether it is involved in the pathogenesis of CCM. The aim of this study is to investigate the expression of serum endocan in patients with CCM and its possible role in the development of CCM. Methods This cross-sectional study was conducted among the patients with liver cirrhosis who were consecutively admitted to Beijing YouAn Hospital, Capital Medical University, from January 2019 to January 2021, and according to the presence or absence of CCM, the patients were divided into CCM group with 19 patients and non-CCM group with 106 patients. ELISA was used to measure the serum level of endocan, and its correlation with liver function and cardiac function was analyzed. The independent-samples t test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U rank sum test was used for comparison of continuous data with skewed distribution between two groups; the chi-square test was used for comparison of categorical data between groups. A Pearson or Spearman correlation analysis was used to investigate the correlation between indicators, and the receiver operating characteristic (ROC) curve was used to assess the CCM predictive model. Results The CCM group had a significantly higher expression level of serum Endocan than the non-CCM group (2.69±0.43 ng/mL vs 2.23±0.52 ng/mL, t=2.247, P=0.034). The patients with compensated cirrhosis had a significantly lower expression level of serum endocan than those with decompensated cirrhosis (2.41±0.37 ng/mL vs 2.72±0.49 ng/mL, t=3.214, P=0.02). In the CCM group, the serum level of endocan was positively correlated with Child-Pugh score (r=0.509, P=0.026) and MELD-Na score (r=0.484, P=0.036) and was negatively correlated with mean arterial pressure (r=-0.591, P=0.013) and mitral ratio of peak early to late diastolic filling velocity (r=-0.515, P=0.042). The serum endocan had an area under the ROC curve of 0.658 (95%CI: 0.522~0.781) in predicting CCM, when the cut-off value was 2.61 ng/mL, the sensitivity was 67.1% and the specificity was 73.7%. Conclusion There is a certain association between serum endocan and CCM, and serum endocan may be involved in the pathogenesis of CCM. -
