AI发现特定心脏病准确率已超过人类专家?心电图迎来技术飞跃

在这项最新的研究中,人工智能模型接受了23万名患者超过120万对的心电图-超声心动图的对照训练,以检测多种形式的结构性心脏病。此后,团队对近 85000名此前未做过超声心动图检查且正在接受心电图检查的患者使用了EchoNext筛查工具,EchoNext识别出超过7500名存在未确诊的结构性心脏病的高风 险。在这些被EchoNext认定为高风险的人群中,有超过一半人接受了超声心动图检查。结果显示,AI工具对结构性心脏病诊断的准确率高达77.3%。 研究团队将EchoNext模型与人类心脏病专家进行了比较,共有13位心脏病专家对3200份心电图的评估(其中1600份使用AI辅助,1600份未使用AI辅助,每 位心脏病专家平均评估了246份心电图)来诊断结构性心脏病。结果显示,在未使用AI辅助的情况下,心脏病专家的准确率为64%;在使用AI辅助的情况 下,心脏病专家的准确率提升至69.2%,但仍低于EchoNext模型检测的77.3%的准确率。 由于缺乏常规且经济有效的筛查测试,许多有结构性心脏问题的人直到心脏功能严重受损时才被发现。 早期发现结构性心脏病对于改善预后至关重要,但广泛筛查仍然受限于超声心动图等影像工 ...
Nature重磅:AI利用常规心电图发现结构性心脏病,准确率超越人类心脏病专家

结构性心脏病 (SHD) , 是一类日益流行的疾病, 包括影响心脏瓣膜、心室壁或心腔的疾病,例如心脏瓣膜病、右心和左心衰竭、肺动脉高压以及左心室肥 厚,在全球范围内影响着数千万人。 在疾病进程的早期阶段发现患有结构性心脏病 (SHD) 的患者,已被证明能够降低死亡率、减少治疗成本并提高生活质量。然而,由于缺乏常规且经济实惠的筛 查测试,许多有结构性心脏问题的人直到心脏功能严重受损时才被发现。 多种类型的 结构性心脏病,往往在疾病晚期才出现症状。所有类型的 结构性心脏病 都可以通过 超声心动图 明确诊断,但这种诊方法成本高、需要专业知识以及 合适的患者选择,限制了其全面应用。因此,迫切需要更好地对患者进行风险分层,并确定哪些患者应转诊进行超声心动图检查,从而提高结构性心脏病的诊断 率和早期治疗率。 2 025 年 7 月 16 日,哥伦比亚大学和 纽约长老会医院的研究人员合作,在国际顶尖学术期刊 Nature 上发表了题为: Detecting structural heart disease from electrocardiograms using AI 的研究论文。 撰文丨王聪 编辑丨王多鱼 排版丨水成文 ...
