AI模型利用PPG数据预测院内卒中风险

研究人员开发了一种利用光电容积脉搏波图(PPG)衍生的血流动力学特征来分类院内卒中风险状态的方法。通过分析住院期间发生卒中的患者的连续监测数据,该研究利用了LLM辅助管道从临床笔记中识别卒中锚点。在PPG数据上训练了一个ResNet-1D分类器,在两个不同的患者队列中,在不同的预测时间范围内均取得了较高的F1分数和AUC。与传统的临床和EHR比较器相比,PPG模型表现出优越的性能,尽管研究结果是回顾性的,并未建立临床警报或经过验证的预测提前期。 AI

影响 这项研究展示了AI通过分析生理信号来增强对危重医疗事件早期检测的潜力,可能改善患者的治疗效果。
