Smartwatches might predict whether there's higher risk of heart failure
A recent study performed by UCL researchers claimed that wearable gadgets such as smartwatches might be used to predict a higher risk of developing heart failure and abnormal heart rhythms in later life.
The peer-reviewed study, published in The European Heart Journal - Digital Health, looked at data from 83,000 people who had undergone a 15-second electrocardiogram (ECG) comparable to the kind carried out using smartwatches and phone devices.
The researchers identified ECG recordings containing extra heartbeats which are usually benign but, if they occur frequently, are linked to conditions such as heart failure and arrhythmia (irregular heartbeats).
They found that people with an extra beat in this short recording (one in 25 of the total) had a twofold risk of developing heart failure or an irregular heart rhythm (atrial fibrillation) over the next 10 years. The ECG recordings analysed were from people aged 50 to 70 who had no known cardiovascular disease at the time.
Heart failure is a situation where the heart pump is weakened. It cannot often be treated. Atrial fibrillation happens when abnormal electrical impulses suddenly start firing in the top chambers of the heart (atria) causing an irregular and often abnormally fast heart rate. It can be life-limiting, causing problems including dizziness, shortness of breath and tiredness, and is linked to a fivefold increased risk in stroke.
Lead author Dr Michele Orini (UCL Institute of Cardiovascular Science) said: "Our study suggests that ECGs from consumer-grade wearable devices may help with detecting and preventing future heart disease.
"The next step is to investigate how screening people using wearables might best work in practice.
"Such screening could potentially be
