An AI-equipped foot scanner placed at one’s bedside could be a lifesaving companion to those living with a risk of heart failure.

Developed by Heartfelt Technologies in concert with the UK’s National Institute of Health, the scanner takes 1,800 photos of a person’s two feet and analyzes them for signs of a fluid buildup called oedema, one of three best indicators of oncoming heart failure.

Heart failure occurs when the heart’s inability to pump blood properly results in a buildup of fluid in the lungs and a lack of blood-derived oxygen reaching vital organs.

Dr. Philip Keeling, the lead author on a study debuting the invention who is also a consultant cardiologist at the South Devon National Health Service Foundation Trust, explained why such a device would be a key tool in combating heart failure, something which affects 1 million Brits every year.

“This device detects one of the big three warning signs for people with heart failure before they end up in hospital,” he wrote, according to the BBC.

“Only about half of people admitted to hospital with heart failure currently get assigned an early review by a heart failure nurse who can check to see if they are suffering a harmful build-up of fluid because their heart is not working properly.”

“Amid a shortage of heart failure nurses, a device like this can be like a virtual nurse, tracking people’s health.”

    • The study which Dr. Keeling helped run involved 26 patients across five NHS trusts. Alerts given by the device of potential heart failure came between eight and 19 days in advance of a hospitalization, giving a mean prediction time of 13 days, which is enough for measures to be taken that could prevent hospitalizations.

    Six hospitalizations occurred during the trial period, and the device accurately predicted 5 of them. 82% of patients decided to keep the device after it ended.

    “This small study suggests a simple device could significantly improve outcomes for at-risk patients with heart failure by keeping them out of hospital,” said Dr. Bryan Williams. Chief Scientific and Medical Officer at the British Heart Foundation which was not involved with the study.
