A new Israeli app can sound an alarm before congestive heart failure starts by analyzing only the user’s voice.
A study of recovered patients, the app predicted 82% of relapses before they happened.
HearO “listens” to audio samples that users have recorded on their smartphones and alerts them if they are at imminent risk of congestive heart failure. It works by detecting irregularities in a person’s speech and comparing them to the healthy “reference” voice. One of both detect abnormalitiesDoctors are immediately informed so that they can take preventive measures.
The new study was conducted by Cordio Medical, the company behind the app, in collaboration with Beilinson Hospital, Barzilai Medical Center and Galilea Medical Center and Clalit Health Services Cardiovascular Centers. It is currently undergoing peer review.
patients suffering heart failure and therefore they used the HearO app at home and sent audio samples in Hebrew, Arabic, or Russian, as they were considered more likely to relapse. 180 patients recorded multiple clips per day for two years, meaning there were 460,000 clips reviewed for the study.
Heart failure occurs when the contractile ability of the heart muscle deteriorates over time or there is a mechanical problem that limits its ability to contract. fill with blood. The heart becomes unable to meet the body’s need for blood, and blood returns to the heart faster than it can pump. The heart tightens; hence the term congestive heart failure.
As expected, around a third of patients experienced heart failure over the two years of the study, Cordio Medical CEO Tamir Tal said. When their medical records were matched with the app’s audio analysis, the app predicted failure in 82% of cases. He detected the warning signs an average of 18 days before the event.
The study design, which was reviewed by ethics committees, meant that patients did not receive real-time alerts, but Tal said that once the app goes live, doctors will have the opportunity to switch medications or provide care, which could prevent many cases. recurrence of heart failure.
he said so Study results show technology can save lives and “significantly reduce number of hospitalizations due to congestive heart failure.
The technology has recently received approval from the Ministry of Health and European Union. It is expected to receive FDA approval by the end of 2023. Tal said the app complies with the US Health Insurance Portability and Accountability Act, which sets privacy standards, including requiring patients to consent to all use of your data.
Users talk to their phones for one minute in a quiet room several times a day, and the file is analyzed by the computer. artificial intelligence. “Just like when you call your mom and she can tell right away that you’re not feeling well. the app uses artificial intelligence to ‘read’ your voice and can tell when things are not as they should beTal explained.
“Cardiologists have the ability to hear complications in their patients’ speech, but it’s often too late as patients often have to be hospitalized at this point. However, our voice has a lot of data waiting to be abused. By constantly monitoring people and leveraging that data, this platform is a life-changing solution. It could be,” he added.
