14-year-old prodigy develops AI that diagnoses heart disease in 7 seconds

An Indian-American boy has created an AI-powered smartphone app capable of detecting heart disease in just seven seconds through sound analysis, achieving an impressive accuracy rate of 96% and aiming to help underserved communities globally.



Siddharth Nandyala, 14, recently developed Circadian AI, a smartphone application designed to analyze heart sounds rapidly and conveniently diagnose cardiovascular conditions.

Originally from Anantapur, India, and now based in Frisco, Texas, Siddharth is the world's youngest AI-certified professional, holding certifications from Oracle Corporation, a leading American tech company known for its database software and cloud computing services, and ARM, a British semiconductor and software design company, according to CNBC.

With Circadian AI, Siddharth is pioneering new possibilities in accessible healthcare diagnostics. The app uses advanced algorithms to analyze heart sounds and deliver instant diagnostic results. Circadian AI has already been tested on more than 15,000 patients in the U.S. and 700 in India, demonstrating an accuracy rate of up to 96%.

Speaking with India Today last week, Nandyala explained how the app works and what inspired him: "What Circadian AI essentially is, is an automated tool that just with 7 seconds of heart sound recording, can give you a detailed synopsis of whether your heart has any abnormalities or whether you have a healthy heart."

"You just need to place it near the heart, record for 7 seconds, and it gives a diagnostic. It can detect over 40 types of cardiovascular diseases," he added.

He clarified that currently, the app is intended for clinical screening in hospital settings.

According to India Today, Circadian AI recently underwent rigorous trials at the Guntur Government General Hospital (GGH) in Andhra Pradesh, India, where it successfully demonstrated swift and accurate detection capabilities.

At GGH Guntur, the AI screened 505 patients in one study, identifying 10 cases of cardiovascular disease. A second study at the same hospital screened 863 patients, detecting 16 cardiovascular disease cases. Additionally, at GGH Vijayawada, the AI app screened 992 individuals, flagging 19 with potential heart issues.

"I am very impressed by Siddharth’s extraordinary talent and dedication to using technology for the benefit of humankind," Andhra Pradesh Chief Minister N. Chandrababu Naidu wrote on X on March 17 after meeting Nandyala.

"At such a young age, he is an inspiration to us all. I wholeheartedly encourage him to pursue his passion for healthcare technology and assure him of our full support in all his endeavours."

Nandyala emphasized that his goal is not merely to create the most advanced diagnostic tool, but rather one that is accessible and easy to use.

Nandyala completed his studies at Lawler Middle School in Texas and is currently pursuing a bachelor's degree in computer science at the University of Texas at Dallas.

In addition to his contributions to healthcare, Siddharth is also an accomplished tech entrepreneur. He founded and leads STEM IT, an initiative dedicated to advancing STEM education among students worldwide. Through STEM IT, he equips young learners with skills in coding, robotics, and AI, inspiring them to embrace technology as a tool for innovation.
