Abstract

Stroke includes both hemorrhagic and ischaemic stroke, and with the rising incidence of stroke, the mortality rate of hemorrhagic stroke is higher than that of ischaemic stroke, accounting for 15% of the stroke mortality rate. In this area, clinically intelligent diagnosis and treatment plays an important role. By integrating imaging features, patient clinical information, treatment plans and diagnosis, accurate personalized efficacy assessment and prognosis prediction can be achieved. In this study, machine learning models (Random Forest, XGBoost, logistic regression, LGBoost, and AdaBoost) for the exploration of factors associated with the risk of haematoma expansion (HE) were developed based on patients' diagnostic data. mRS scores were used to assess the prognostic status of the patients, Principal Component Analysis was used for data dimensionality reduction, and Spearman Correlation Analysis was used to analyze the features' direct correlation. Five machine learning models were applied to predict the probability of HE and the prognosis of hemorrhagic stroke in patients. The models were tuned using grid search and ten-fold cross-validation methods to obtain more accurate predictions. The results of the study showed that the mRS index and factors such as history of diabetes, history of coronary heart disease, haematoma volume and age were closely related to the prognosis of patients. Among them, RF and XGBoost performed well in predicting the probability of HE, with the area under the ROC curve reaching 0.98, while LGBoost performed best in predicting the prognostic status of hemorrhagic stroke patients.

基于机器学习的出血性脑卒中临床诊断与治疗模型
卒中包括出血性卒中和缺血性卒中,随着卒中发病率的上升,出血性卒中的死亡率高于缺血性卒中,占卒中死亡率的15%。在这方面,临床智能化诊疗发挥着重要作用。通过整合影像学特征、患者临床信息、治疗方案和诊断,实现准确的个性化疗效评估和预后预测。在这项研究中,基于患者的诊断数据,开发了机器学习模型(随机森林、XGBoost、逻辑回归、LGBoost和AdaBoost),用于探索与血肿扩张(HE)风险相关的因素。采用mRS评分评价患者预后状况,采用主成分分析进行数据降维,采用Spearman相关分析分析各特征的直接相关性。应用5种机器学习模型预测出血性脑卒中患者HE发生概率及预后。使用网格搜索和十倍交叉验证方法对模型进行了调整,以获得更准确的预测。研究结果显示,mRS指数与糖尿病史、冠心病史、血肿体积、年龄等因素与患者预后密切相关。其中,RF和XGBoost对HE发生概率的预测效果较好,ROC曲线下面积达到0.98,而LGBoost对出血性脑卒中患者预后状况的预测效果最好。
