摘要:

目的:基于广州市基本公共卫生项目中医体质量表和常规体检指标,分析新发心脑血管事件(MACCE)的相关危险因素,建立相应列线图模型并评价其有效性。方法:纳入广东省广州市531名65~90岁老年人(MACCE组382人,非MACCE组149人),按7∶3比例将样本随机分为训练集(n=372)与验证集(n=159)。先经单因素Logistic回归分析筛选变量,再用LASSO回归确定建模因子,最后以多因素Logistic回归分析筛选MACCE独立危险因素并构建列线图模型。通过校准曲线、内部bootstrap验证、ROC曲线分析及验证集验证评估模型性能。结果:训练集单因素分析显示平和质、气虚质、糖尿病病史、高血压病史、甘油三酯升高和低密度脂蛋白升高差异有统计学意义(P<0.05)。LASSO回归确定15个预测因子,多因素分析确定7个独立影响因素(气虚质、痰湿质、糖尿病病史、高血压病史、甘油三酯升高和低密度脂蛋白升高)构建列线图模型。校准曲线显示模型校准性能良好,训练集C指数为0.846,ROC值为0.835;验证集C指数为0.857,AUC值为0.844。结论:气虚质、痰湿质、糖尿病病史、高血压病史、甘油三酯升高和低密度脂蛋白升高是新发心脑血管事件的独立危险因素。本研究建立的列线图模型有良好的预测效能和区分度,可预测新发心脑血管事件的风险。

Abstract:

Objective: Based on the Chinese Medicine Physical Examination Scale of the Guangzhou Basic Public Health Program and the indicators of routine physical examination, to analyze the risk factors associated with new-onset cardiovascular and cerebrovascular events (MACCE), then to establish the corresponding columnar graphical model, and evaluate its validity. Methods: A total of 531 elderly people aged 65-90 years (382 in the MACCE group and 149 in the non-MACCE group) were enrolled in Guangzhou City, Guangdong Province, China, and the samples were randomly divided into a training set (n=372) and a validation set (n=159) according to a 7:3 ratio. The variables were first screened by one-way logistic regression analysis, then the modeling factors were determined by LASSO regression, and finally the independent risk factors for MACCE were screened by multifactorial logistic regression analysis, and the columnar graph model was constructed. The performance of the model was evaluated by calibration curves, internal bootstrap validation, ROC curve analysis, and validation set. Results: One-way analysis of the training set showed statistically significant results for balanced constitution, qi-deficient constitution, history of diabetes, history of hypertension, elevated triglycerides, and elevated low-density lipoprotein (LDL) (P<0.05). 15 predictors were identified by LASSO regression, and 7 independent factors (qi-deficiency constitution, phlegm-dampness constitution, history of diabetes, history of hypertension, elevated triglycerides and LDL) were identified by multivariate analysis for the construction of the columnar graph model. The calibration curve showed that the model was well calibrated, with a training set C-index of 0.846 and a ROC value of 0.835, and a validation set C-index of 0.857 and an AUC value of 0.844. Conclusion: Qi-deficiency constitution, phlegm-dampness constitution, history of diabetes, history of hypertension, triglyceride elevation, and low-density lipoprotein elevation are the independent risk factors for the occurrence of cardiovascular and cerebrovascular events. The column-line graph model developed in this study had good predictive efficacy and discrimination to predict the risk of new cardiovascular and cerebrovascular events.
