Artificial intelligence stethoscope capable of detecting 3 heart diseases within
Stethoscope with artificial intelligence

The first artificial intelligence (AI) stethoscope has gone beyond listening to heartbeats.

Researchers at Imperial College London and Imperial College Healthcare NHS Trust found that an AI-powered stethoscope could detect heart failure at an early stage.

Results of the TRICORDER study, published in BMJ Journals, found that the AI-powered stethoscope can help doctors identify three heart conditions in just 15 seconds.

According to the British Heart Foundation (BHF), which partly funded the study, researchers analyzed data from more than 1.5 million patients, focusing on people with symptoms of heart failure such as shortness of breath, swelling and fatigue.

A total of 12,725 patients were screened with the new AI stethoscope technology. The patients were found to be twice as likely to be diagnosed with heart failure compared to similar patients who were not screened with the tool.

Patients examined with a stethoscope were also about 3.5 times more likely to be diagnosed with atrial fibrillation (abnormal heart rhythm), which increases the risk of stroke.

Patients with the smart stethoscope were also twice as likely to receive a diagnosis of heart valve disease, where one or more valves do not function properly.

All three of these conditions require early diagnosis to receive potentially life-saving treatment, according to the BHF press release.

Dr. Patrik Bächtiger, a clinical lecturer at Imperial College London, noted in a statement that the design of the stethoscope, which was developed in 1816, has not changed in 200 years.

"It's incredible that a smart stethoscope can be used for a 15-second examination, and then AI can quickly provide a test result that indicates whether someone has heart failure, atrial fibrillation, or heart valve disease," he wrote.

Dr. Sonya Babu-Narayan, clinical director at the British Heart Foundation and consultant cardiologist, also commented in a statement that these heart conditions are often diagnosed at advanced stages when patients arrive at hospital for emergency care.

"Given an earlier diagnosis, people can access the treatment they need to help them live well for longer," she said.

The artificial intelligence stethoscope records an ECG of electrical signals from the patient's heart. The microphone on the device also records the sound of blood flowing through the heart.

The recorded information is analyzed by artificial intelligence algorithms that have been trained on health data from tens of thousands of people. The tool then generates a test score for heart failure risk.

A special algorithm can detect atrial fibrillation, which often shows no symptoms.

However, researchers suggest there needs to be more integration of the technology into general practice, as 70% of practitioners with smart stethoscopes stopped using them after 12 months.

The study also found that two-thirds of people suspected of having heart failure were found not to have the condition after further blood tests or heart scans.
