目的 分析终末期肾脏病(ESRD)维持性透析患者并发心血管疾病的危险因素,并依此构建风险预测列线图模型.方法 回顾性纳入2020年3月~2022年11月我院收治行维持性透析的ESRD患者183例,根据有无并发心血管疾病将其分为并发组(92例)和未并发组(91例).收集两组患者的一般资料并分组进行比较.采用多因素logistic回归分析评估ESRD维持性透析患者并发心血管疾病的危险因素,并基于此构建列线图模型.采用Bootstrap法对列线图模型进行验证,并绘制校准度曲线图评价列线图模型校正度.采用受试者工作特征(ROC)曲线评估列线图模型的预测价值.结果 并发组年龄≥60岁、糖尿病病史、贫血患者比例及透析龄、尿酸、低密度脂蛋白胆固醇、血磷水平均高于未并发组(P<0.05).多因素logistic回归分析结果显示,年龄≥60岁、贫血、透析龄、尿酸、血磷水平均为影响ESRD维持性透析患者并发心血管疾病的危险因素(P<0.05).根据上述危险因素构建列线图模型,ROC曲线结果显示,列线图预测ESRD维持性透析患者并发心血管疾病的ROC曲线下面积(AUC)为0.827,敏感度为80.43%,特异度为79.12%;列线图模型的C-index为0.833,校准曲线与理想曲线拟合度较好.结论 年龄≥60岁、贫血、透析龄、尿酸、血磷水平均为ESRD维持性透析患者并发心血管疾病的危险因素,据此构建列线图模型能更加直观地预测ESRD维持性透析患者并发心血管疾病的风险,且预测价值的好.
Objective To analyze the risk factors of cardiovascular disease in maintenance dialysis patients with end-stage renal disease(ESRD),and to construct a nomogram model for risk prediction.Methods A total of 183 ESRD patients on maintenance dialysis admitted to our hospital from March 2020 to November 2022 were retrospectively enrolled.According to the presence or absence of cardiovascular disease,they were divided into concurrent group(92 cases)and non-concurrent group(91 cases).General data of patients in both group were collected and grouped for comparison.Multivariate logistic regression analysis was used to evaluate the risk factors of cardiovascular disease in ESRD maintenance dialysis patients,and a nomogram model was constructed based on this.Bootstrap method was used to verify the nomogram model,and the calibration curve was drawn to evaluate the calibration degree of the nomogram model.The receiver operating characteristic(ROC)curve was used to evaluate the predictive value of the nomogram model.Results Age≥60 years old,history of diabetes,proportion of patients with anemia,age on dialysis,uric acid,low-density lipoprotein cholesterol and blood phosphorus levels in concurrent group were higher than those in non-concurrent group(P<0.05).The results of multivariate logistic regression analysis showed that age ≥ 60 years old,anemia,age on dialysis,uric acid and blood phosphorus levels were all risk factors for ESRD maintenance dialysis patients complicated with cardiovascular disease(P<0.05).Based on the above risk factors,a nomogram model was constructed and the ROC curve results showed that the area under the ROC curve(AUC)of the nomogram for predicting cardiovascular disease in ESRD maintenance dialysis patients was 0.827,with sensitivity of 80.43%and specificity of 79.12%.The consistency index of the nomogram model was 0.833 and the calibration curve has a good fit with the ideal curve.Conclusion Age≥60 years old,anemia,age on dialysis,uric acid and blood phosphorus levels are all risk factors for ESRD maintenance dialysis patients complicated with cardiovascular disease.Based on this,constructing a nomogram model can more intuitively predict the risk of ESRD maintenance dialysis patients complicated with cardiovascular disease,and the prediction efficiency is good.
