研究目的:

1.主要目的 (Primary Objective): 开发并验证一个深度学习模型,该模型通过融合代表微循环状态的眼底影像特征与代表大血管局部病变的冠脉造影影像特征,用于预测由血管内超声(IVUS)定义的“高危/易损斑块”的存在风险。主要评价指标为模型的受试者工作特征(ROC)曲线下面积(AUC)。 2.次要目的 (Secondary Objectives): 比较多模态融合模型与仅使用微循环(眼底)特征的模型的预测效能。 确定该融合模型的最佳预测阈值,并计算其灵敏度、特异度、阳性预测值(PPV)和阴性预测值(NPV)。 探索并识别与IVUS定义的高危斑块相关的、独立的微循环(眼底)和大血管(冠脉造影)影像学预测因子  

Objectives of Study:

1. Primary Objective. To develop and validate a deep learning model for predicting the risk of the presence of "high-risk/vulnerable plaques" as defined by intravascular ultrasound (IVUS) by fusing fundus imaging features representing the state of the microcirculation with coronary imaging features representing the localization of lesions in large vessels. The primary evaluation metric is the area under the curve (AUC) of the modeled subject operating characteristic (ROC). 2. Secondary Objectives. To compare the predictive efficacy of a multimodal fusion model with a model using only microcirculatory (fundus) features. Determine the optimal prediction threshold for the fusion model and calculate its sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). Explore and identify independent microcirculatory (fundus) and macrovascular (coronary angiography) imaging predictors associated with IVUS-defined high-risk plaques
