A 14-year-old software developer from India, Siddharth Nandiyala, has launched an innovative mobile application called Circadian AI, which can detect heart diseases in just seconds, reports Smithsonian Magazine.

Cardiovascular diseases are among the leading causes of death globally, yet their early symptoms often go unnoticed. This is due to the fact that diagnosing symptoms typically requires expensive procedures or complex tests, which are not accessible to many patients, especially in poorer nations. Nandiyala aimed to change this by developing an affordable and non-invasive diagnostic method.

The Circadian AI app utilizes the smartphone's microphone to record the patient's heartbeat. The recorded sound undergoes noise cancellation processing and is then analyzed in the cloud using machine learning algorithms. In just a few seconds, the app can detect arrhythmias, valve issues, early signs of heart failure, or ischemic heart disease.

The app has already undergone clinical trials: it was tested on 15,000 patients in the USA and 3,500 in India. The accuracy of detecting heart conditions exceeded 96%.

Currently, Circadian AI is available only for medical professionals as it is undergoing regulatory approval. In the future, Nandiyala plans to expand its functionality to also diagnose lung diseases such as pneumonia and thromboembolism.

This technology could become an essential tool for early disease diagnosis, especially in areas with limited access to medical services.
