人工智能听诊器检测到心脏阀疾病,50岁以上的成年人的精确度达到92%,超过传统的听诊器。 An AI stethoscope detected heart valve disease with 92% accuracy in adults over 50, outperforming traditional stethoscopes.

根据2026年2月5日发表在《欧洲心脏杂志-数字健康》上的一项美国研究，一项针对357名50岁及以上成年人的研究显示，一款人工智能驱动的数字听诊器检测中度至重度瓣膜性心脏病的灵敏度达92.3%，这是传统听诊器46.2%的两倍多。 An AI-powered digital stethoscope detected moderate to severe valvular heart disease at 92.3% sensitivity—more than double traditional stethoscopes’ 46.2%—in a U.S. study of 357 adults aged 50 and older, according to research published in the European Heart Journal - Digital Health on February 5, 2026. 该工具利用机器学习来分析心脏声音,在确定一种由于微妙或缺乏症状而往往遗漏的病症方面显示了希望,有可能促成早期治疗和减少住院。 The tool, using machine learning to analyze heart sounds, showed promise in identifying a condition often missed due to subtle or absent symptoms, potentially enabling earlier treatment and reducing hospitalizations. 研究人员虽然略有降低具体性,但认为早期发现的好处大于风险,并强调医生在解释结果方面仍然必不可少。 While slightly lowering specificity, researchers believe the benefits of earlier detection outweigh the risks, and emphasize that doctors remain essential in interpreting results.
