美敦力与Tempus AI联合发布的ALERT临床试验数据显示，基于人工智能的电子健康记录预警系统能够有效识别重度心脏瓣膜病变患者，并促使临床医生采取更及时的干预措施。该研究证实，AI驱动的自动化通知机制可将确诊到专科随访的时间缩短40%，显著提升诊疗效率。
通过实时分析超过50万个结构化电子病历数据点，该算法能精准捕捉主动脉瓣狭窄的早期征兆。试验组接收AI警报的医疗机构中，患者接受超声心动图检查的比例较对照组提升2.3倍，且后续进行瓣膜置换术的转化率提高67%。
这项突破性技术有望解决传统诊疗模式下疾病检出率低、随访流失率高的痛点。研究团队指出，下一步将探索将该系统扩展至二尖瓣反流等其他结构性心脏病领域，构建更全面的智能诊疗生态体系。
