Acarix Study Shows Acoustic Sensor Rivals Blood Test for Heart Failure
Oklahoma City – September 16, 2026 -- Acarix AB announced that a peer-reviewed study published in PLOS Digital Health found its seismocardiography (SCG) technology can detect heart failure with diagnostic accuracy comparable to NT-proBNP, the current standard blood test, while producing significantly fewer false positives.
SCG algorithm matches blood test accuracy with far higher specificity
Researchers at Aalborg University Hospital, Aarhus University Hospital and Odense University Hospital enrolled 218 patients, including 198 referred by general practitioners for suspected heart failure and 20 with previously confirmed HFrEF. Using machine learning, the team built two SCG-based scores: an 'AnyHF-score' to flag heart failure of any type, and an 'HFrEF-score' targeting the more severe reduced-ejection-fraction form of the condition.
