FDA approves patient app for CardioMEMS readings; AI chatbots misjudge which home blood pressure monitors are validated

THE SHORT READ

The Food and Drug Administration (FDA) approved updates letting patients with Abbott's implanted CardioMEMS sensor see their pulmonary artery pressure readings on a smartphone, the company said. Separately, three of four popular artificial intelligence (AI) tools were right only about 63% to 83% of the time on whether home blood pressure monitors were validated, according to an American Heart Association abstract presented at the association's Hypertension Scientific Sessions 2026.

    FDA approves CardioMEMS updates letting heart failure patients view pulmonary artery pressure readings on phones
    The Food and Drug Administration (FDA) approved updates to Abbott's CardioMEMS HF System, which measures pulmonary artery pressure through a sensor implanted in the pulmonary artery, the company said Oct. 5. Through the CardioGuide HF App, patients will be able to view their readings on their smartphones, and a Dynamic Treatment Plan feature lets clinicians set up personalized medication adjustment plans. Abbott said it plans to make the app and the feature available later this year.

    Gemini, ChatGPT, Copilot and Perplexity often misidentify validated home BP monitors in test of 324 devices
    Researchers asked four AI tools about each of 324 home blood pressure monitors in a study presented at the American Heart Association's Hypertension Scientific Sessions 2026. Google Gemini answered correctly 86% to 91% of the time depending on how questions were phrased, and ChatGPT, Copilot and Perplexity about 63% to 83%. All four were less accurate with validated monitors than with unvalidated ones. "People may unknowingly think a device is validated based on the AI tool's inaccurate responses," said Dr. Anna Soriano, a third-year internal medicine resident at the University of Montreal. The abstract has not been peer reviewed.
