摘要:

目的 探讨糖尿病心肌病(DCM)患者血清脂联素(APN)与胰岛β细胞功能指数(HOMA-β)的水平变化,并分析二者与DCM患者心功能损伤的关系。方法 采用回顾性病例对照研究,选取2021年3月—2023年3月医院收治的106例DCM患者纳入观察组,另同期选取106例不伴有心肌病、冠心病及心功能不全的2型糖尿病患者纳入对照组。比较2组一般资料、血清APN、HOMA-β及心功能指标;采用Pearson相关分析APN、HOMA-β与心功能指标的相关性;采用多因素Logistic回归分析DCM的影响因素;采用受试者工作特征(ROC)曲线分析APN与HOMA-β对DCM的评估价值。结果 2组患者年龄、性别、体质量指数、吸烟史、饮酒史、合并症、降糖药物使用情况、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇、总胆固醇、三酰甘油、糖化血红蛋白、血清肌酐、尿酸比较差异无统计学意义(P>0.05),但观察组糖尿病病程长于对照组(P<0.05)。与对照组比较,观察组血清APN、HOMA-β、舒张早期与晚期二尖瓣血流速度比(E/A)、左室射血分数(LVEF)均降低,左心室舒张末期容积(LVEDV)与氨基末端脑钠肽前体(NT-proBNP)水平均升高(P<0.05)。Pearson相关分析显示,APN、HOMA-β均与E/A、LVEF呈正相关,与LVEDV、NT-proBNP呈负相关(P<0.05)。多因素Logistic回归分析显示,糖尿病病程长是发生DCM的危险因素,血清APN、HOMA-β水平高则是DCM的保护因素(P<0.05)。ROC曲线分析显示,血清APN、HOMA-β单独评估DCM的曲线下面积(AUC)分别为0.790(95%CI:0.729~0.843)和0.761(95%CI:0.697~0.816),两者联合评估的AUC提升至0.903(95%CI:0.855~0.940),联合评估模型的诊断效能显著优于APN及HOMA-β单独检测(Z分别为2.974、5.237,均P<0.01)。结论 DCM患者血清APN及HOMA-β水平与心功能损伤指标相关。两者可能是评估DCM及心功能损伤的潜在生物标志物,联合检测价值更高。

Abstract:

Objective To investigate the levels of serum adiponectin (APN) and homeostasis model assessment of β-cell function (HOMA-β) in patients with diabetic cardiomyopathy (DCM), and to analyze their relationship with the occurrence of DCM and cardiac function impairment. Methods A retrospective case-control study was conducted. A total of 106 DCM patients admitted to the hospital from March 2021 to March 2023 were enrolled as the observation group. Another 106 patients with type 2 diabetes mellitus (T2DM) without cardiomyopathy, coronary heart disease, or cardiac insufficiency during the same period were selected as the control group. The general data, serum APN, HOMA-β and cardiac function indicators were compared between the two groups. Pearson correlation analysis was used to evaluate the correlation between APN, HOMA-β and cardiac function indicators. Multivariate Logistic regression analysis was used to analyze the influencing factors of DCM. Receiver operating characteristic (ROC) curve analysis was used to assess the evaluation value of APN and HOMA-β for DCM. Results There were no statistically significant differences in baseline data such as age, gender, BMI, smoking history, drinking history, comorbidities, use of hypoglycemic drugs, HDL-C, LDL-C, TC, TG, HbA1c, Scr and UA between the two groups (P>0.05). However, the duration of diabetes was longer in the observation group than that in the control group (P<0.05). Compared with the control group, levels of serum APN, HOMA-β, the ratio of early to late diastolic mitral inflow velocities (E/A) and left ventricular ejection fraction (LVEF) were decreased, while left ventricular end-diastolic volume (LVEDV) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels were increased in the observation group (P<0.05). Pearson correlation analysis showed that both APN and HOMA-β were positively correlated with E/A and LVEF, and negatively correlated with LVEDV and NT-proBNP (P<0.05). Multivariate Logistic regression analysis showed that a long duration of diabetes was a risk factor for developing DCM, while high levels of serum APN and HOMA-β were protective factors for DCM (P<0.05). ROC curve analysis showed that the area under the curve (AUC) for APN and HOMA-β alone in evaluating DCM were 0.790 (95%CI: 0.729-0.843) and 0.761 (95%CI: 0.697-0.816), respectively. The AUC for their combined evaluation increased to 0.903 (95%CI: 0.855-0.940). DeLong's test indicated that the diagnostic efficacy of the combined evaluation model was significantly superior to that of APN alone (Z = 2.974,P<0.01) and HOMA-β alone (Z = 5.237, P<0.01). Conclusion Serum levels of APN and HOMA-β in DCM patients are correlated with cardiac function impairment indicators. Both may be potential biomarkers for evaluating DCM and cardiac function impairment, and the combined detection has a higher value.
