At the American Heart Association’s Scientific Sessions 2023, groundbreaking research involving an artificial intelligence (AI) smartphone app was presented, showcasing its ability to predict hospitalizations in heart failure patients with remarkable accuracy.
Developed by a team led by Dr. William T. Abraham from The Ohio State University Wexner Medical Center, this app represents a significant advancement in remote patient monitoring.
Heart failure, characterized by the heart’s inability to pump sufficient blood, often leads to symptoms like fatigue, fluid retention, and shortness of breath.
The app aims to offer an early warning system for deteriorating heart conditions by analyzing subtle changes in a patient’s voice.
The study, conducted from March 2018 to April 2023 in Israel, involved 416 adults diagnosed with heart failure. Participants were required to record five sentences daily in their native language using the app.
The AI algorithm, trained with speech measures from 263 participants, was then validated with the remaining 153 participants.
Key findings of the study include:
- The app predicted 76% of heart failure events in the training phase, approximately 24 days before hospitalization or the need for intravenous treatment.
- In the validation phase, the app’s accuracy stood at 71%, predicting heart failure events about three weeks in advance.
- Participants experienced an average of three unnecessary alerts per year, indicating a low rate of false alarms.
The study’s positive results highlight the app’s potential as an effective tool for reducing hospitalization rates and improving patient outcomes in heart failure.
By offering early detection of heart failure symptoms, the app allows for timely medical intervention, potentially keeping patients well and out of the hospital.
While the study shows promising results, its limitation lies in the small number of participants. An ongoing study in the U.S. aims to further train and validate the technology, potentially enhancing its accuracy and reliability.
Conclusion
The development of the Cordio HearO system, a combination of a smartphone app and AI technology, marks a significant leap in managing heart failure.
This innovative approach could revolutionize how patients with heart failure are monitored, offering a non-invasive, efficient, and potentially life-saving tool.
