研究目的:

本研究旨在系统性地解决大血管闭塞(LVO)合并轻型卒中(NIHSS≤5)临床管理中的核心难题——早期神经功能恶化(END)的精准预测与预防。具体研究目的如下: 1. 首要目的:识别END的独立危险因素。 突破单一维度分析的局限,从临床特征、高级神经影像、血液生化标志物三个维度,构建一个全面的危险因素谱,深入剖析各因素对END的独立贡献及相互作用机制。 2. 核心目的:构建并验证一个高精度、临床实用的END风险预测模型。 基于上述多维度数据,利用机器学习算法,整合关键预测指标,开发一个适用于急诊决策的个体化END风险预测工具。该模型的核心价值在于能够量化每位患者的END风险,为治疗策略的选择提供客观依据。 3. 转化目的:提出基于风险分层的个体化干预策略框架。 根据预测模型的风险评分,将患者划分为低危、中危、高危层次,并初步探讨不同层次患者的最佳治疗路径(如强化药物治疗 vs. 积极血管内治疗),为实现“精准医疗”提供前瞻性思路。  

Objectives of Study:

This study aims to systematically address the core challenges in clinical management of large vessel occlusion (LVO) with mild stroke (NIHSS <= 5) by accurately predicting and preventing early neurological deterioration (END). The specific research objectives are as follows: 1. Primary objective: Identify independent risk factors for END. Overcoming the limitations of single-dimensional analysis, construct a comprehensive risk factor spectrum from three dimensions—clinical characteristics, advanced neuroimaging, and blood biochemical markers—to deeply analyze the independent contributions and interaction mechanisms of each factor to END. 2. Core objective: Develop and validate a high-precision, clinically practical END risk prediction model. Based on the multidimensional data above, utilize machine learning algorithms to integrate key predictive indicators and develop an individualized END risk prediction tool suitable for emergency decision-making. The core value of this model lies in its ability to quantify the END risk for each patient, providing an objective basis for treatment strategy selection. 3. Translational objective: Propose a framework for individualized intervention strategies based on risk stratification. According to the risk scores from the predictive model, stratify patients into low-risk, medium-risk, and high-risk categories, and preliminarily explore the optimal treatment pathways for different risk levels (e.g., intensive medical therapy vs. active intravenous thrombectomy), providing a forward-looking approach to achieve "precision medicine."
