研究目的: |
基于可获得的围手术期变量,开发一个用于预测老年髋部骨折患者术后心肌损伤风险的临床预测模型,并利用多中心数据对其进行内部及外部验证。最终成果将转化为直观的列线图评分工具,便于临床床旁快速应用。 |
||||||||||||||||||||||
|
Objectives of Study: |
Based on readily available perioperative variables, we aimed to develop a clinical prediction model for postoperative myocardial injury in older patients with hip fracture and to perform internal and external validation using multicenter data. The final model will be translated into an intuitive nomogram-based scoring tool to facilitate rapid bedside clinical application. |
