研究目的:

通过收集急性A型主动脉夹层(ATAAD)患者临床资料,筛选ATAAD患者体外循环术后发生PPCs的独立危险因素并基于独立危险因素构建一个可视化的临床预测列线图模型。通过多中心数据转换验证,全面评估该模型的区分度、校准度和临床适用性,为临床预测和早期干预这类人群PPCs提供循证学依据。  

Objectives of Study:

By collecting clinical data of patients with acute type A aortic dissection (ATAAD), we identified the independent risk factors for postoperative PPCs in these patients after cardiopulmonary bypass and constructed a visual clinical prediction nomogram model based on these independent risk factors. Through multi-center data conversion verification, we comprehensively evaluated the discrimination, calibration, and clinical applicability of this model to provide evidence-based basis for clinical prediction and early intervention of PPCs in this population.
