New Bluetooth sensor “can detect heart failure 10 days before this happens, even when patients show no symptoms”
- Device worn on chest tracks heartbeat and rhythm, sleep quality and step count
- It pings this data to app that using artificial intelligence to get normal baseline
- Can then detect when the heart function starts to deteriorate before the symptoms occur
A new Bluetooth sensor can detect heart failure 10 days before this happens with an accuracy of up to 80 percent, a study found.
The patch, worn on the chest, works by following heart rate and rhythm, sleep quality, step count, and posture.
It links this data to a smartphone app that uses artificial intelligence to establish a normal baseline for each patient.
From here it can detect when the function of the heart starts to deteriorate before wearers or doctors know something is wrong.
A test with the sensor showed that it accurately predicted the need for hospital treatment more than 80 percent of the time.

On average, this prediction took place 10.4 days before a takeover took place.
Scientists from the University of Utah Health and VA Salt Lake City Health Care System say the technology will reduce the number of emergency admissions.
They followed 100 heart failure patients, with an average age of 68, who wore a self-adhesive sensor patch on their chest for up to three months.
The sensor, manufactured by PhysIQ, monitored heartbeat and rhythm, breathing, walking, sleep, posture and other normal activities.
WHAT IS HEART FAILURE?
The heart cannot pump blood properly through the body.
It usually occurs because the heart has become too weak or stiff.
It is sometimes called congestive heart failure, although this name is not widely used nowadays.
Heart failure does not mean that your heart no longer works. It only needs some support to make it work better.
It can occur at any age, but it is most common in older people.
Heart failure is a long-term condition that gradually gets worse over time.
It cannot usually be cured, but the symptoms can often be controlled for many years.
Symptoms of heart failure
The main symptoms of heart failure are:
- shortness of breath after activity or at rest
- feeling tired and tiring most of the time
- swollen ankles and legs
Some people also experience other symptoms, such as a persistent cough, a rapid heartbeat, and dizziness.
Symptoms can develop rapidly (acute heart failure) or gradually over weeks or months (chronic heart failure).
A warning was triggered when the information deviated from normal and indicated that the patient’s heart failure got worse.
The system accurately predicted the impending hospitalization more than 80 percent of the time.
Dr. Josef Stehlik, lead author of the study, said: “This study shows that we can significantly predict the likelihood of hospitalization for heart failure long before doctors and patients know something is wrong.
‘If we can detect changes in the heart sufficiently early, doctors can initiate rapid interventions that can prevent re-hospitalization and prevent worsening of heart failure.
“There is a high risk of takeover in the 90 days after the first discharge. If we can reduce these acquisition rates through monitoring and early intervention, that is a major advance.
“We even hope that patients who are re-admitted have a shorter stay and that the overall quality of their lives will be better with the help of this technology.”
Heart failure means that the organ cannot function properly. In some cases the heart cannot be filled with enough blood, in other cases it cannot pump blood to the rest of the body with sufficient force.
According to the British Heart Foundation, more than 900,000 people live in the UK with the condition. About 6.5 million adults in the US have heart failure.
Co-author Dr. Biykem Bozkurt of the study added: “People with repeated hospital admissions for heart failure have considerably higher mortality rates.
“Even if patients survive, they have poor functional capacity, poor exercise tolerance, and low quality of life after hospitalization.”
The study was published in American Heart Association magazine, Circulation: Heart Failure.
