A 14-year-old Indian developer, Siddharth Nandyala, has created an innovative mobile application called Circadian AI, which can swiftly detect heart diseases, according to Smithsonian Magazine.

Cardiovascular diseases are a leading cause of death worldwide, yet their early symptoms often go unnoticed. This is largely due to the fact that diagnosing these symptoms typically requires expensive procedures or complex tests, which are not accessible to many, particularly in poorer countries. Nandyala aimed to change this situation by developing an affordable and non-invasive diagnostic method.

The Circadian AI app utilizes the smartphone's microphone to record the user's heartbeat. The recorded sound is processed using noise-cancellation technology and then analyzed in the cloud with 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, tested on 15,000 patients in the USA and 3,500 in India, achieving an accuracy rate of over 96% in detecting cardiac conditions.

Currently, Circadian AI is available only to medical professionals as it is undergoing regulatory review. In the future, Nandyala plans to expand its functionality to include the diagnosis of lung diseases such as pneumonia and thromboembolism.

This technology could serve as a vital tool for early disease diagnosis, especially in areas with limited access to medical services.
