This 14-Year-Old’s AI App Can Detect Heart Disease in Seconds — Even Obama and Biden Are Impressed

Indian-American Teen Siddarth Nandyala Is Turning Heads With His Groundbreaking AI setup

A STEM Kit Sparked It All

At just 14 years old, Indian-American teen Siddarth Nandyala has already accomplished what many only dream of. He’s founded two tech startups, received praise from former U.S. Presidents Barack Obama and Joe Biden, and is using AI to detect heart disease—all before finishing high school.

It all began when Siddarth was just 7 years old, and he got his first STEM kit.

“The idea of creating something out of nothing completely fascinated me,” he says. That spark has now grown into a blazing passion for tech and innovation.

A Blend of Cultures, A Foundation for Innovation

Born in Hyderabad, India, Siddarth moved to the United States at a young age. He credits his Indian roots for teaching him values like persistence and respect for education, while America inspired him to think big and act boldly.

This fusion of cultures created a powerful mindset: ambition with empathy—an ideal combination for a healthtech innovator.

From Frustration to Innovation: STEM IT

Siddarth’s first company, STEM IT, was born out of a frustration with how traditional education fails to connect theory with real-world application.

“They teach surface-level theory but don’t show how things really work,” he explains.

STEM IT provides hands-on tools that allow students to build and understand the mechanics behind technology, helping the next generation of innovators learn by doing.

Building Second Chances: Circadian AI

Siddarth’s second startup, Circadian AI, is already changing lives. This AI-powered tool can detect heart diseases in seconds—using nothing but a smartphone and a patient's heartbeat.

Here’s how it works:

• Place a phone on the 5th intercostal space (left chest area)
• The app records heart sounds
• AI analyzes the sound
• A detailed heart health report appears almost instantly

“We’re not just building software. We’re building second chances,” Siddarth says emotionally.

Real Results in Indian Hospitals

Circadian AI was recently tested in government hospitals in Andhra Pradesh, where the results shocked even seasoned doctors.

At Guntur General Hospital, the app:

• Screened 505 patients in the first phase
• Detected 10 hidden cases of cardiovascular disease (CVD)

In a second study:

• Screened 863 patients
• Detected 16 CVD cases

At Vijayawada Government Hospital:

• Screened 992 people
• Found 19 with serious heart conditions

All flagged patients were later clinically verified using ECGs and 2D echo tests—and most results matched.

Why You Can’t Download It—Yet

Although the tech is incredibly promising, Circadian AI isn’t available to the general public.

“It’s meant for clinical screening in hospital settings,” Siddarth explains. “Not for casual or at-home use—at least for now.”

But the potential is massive, especially for rural or low-resource areas where access to expensive heart diagnostics is limited.

What Makes It Work? AI + Real-World Testing

It took Siddarth seven months to bring Circadian AI to life:

• Collected real heart sounds from patients
• Trained a custom AI model
• Built a user-friendly mobile interface
• Conducted live tests in hospitals for accuracy

A Family of Support and Curiosity

Siddarth’s father, Mahesh Nandyala, noticed his son's gift early on.

“He used to take apart gadgets—not to break them, but to understand how they worked.”

Instead of stopping him, his parents gave him tools, trust, and time—the perfect environment to fuel his creativity.

Ethics and AI in Healthcare

Siddarth knows that powerful technology comes with responsibility. His top concern?

“Ethics must be at the core,” he says. That includes:

• How AI models are trained
• Who they represent
• If results are understandable to both patients and doctors

What’s Next? Lung Disease Detection and Mixed Reality Learning

Circadian AI is evolving. Siddarth is working to expand its abilities to detect lung diseases by integrating respiratory analysis.

In education, he dreams of combining mixed reality with AI tutors to create immersive, interactive science lessons.

“Imagine walking inside a simulation of a working engine or a living cell,” he says. “That could completely change how we learn.”

Words of Wisdom From a Teen Prodigy

For other young dreamers, Siddarth offers this:

“Innovation is the heartbeat of progress. The tools are in your hands—you just have to begin.”

Outside Tech? Chess and Golf Keep Him Grounded

To unwind, Siddarth loves playing golf and chess. He says golf clears his mind, and chess sharpens the strategy skills that carry over into his tech life.

He draws deep inspiration from Dr. A.P.J. Abdul Kalam, calling the late Indian President a guiding light for young Indian innovators.

Siddarth Nandyala is not just a teen tech prodigy—he's a reminder that innovation doesn't have an age limit. From bedroom experiments to life-saving medical tools, he’s redefining what young minds can achieve.

With leaders like Obama and Biden applauding him, and hospital doctors relying on his AI to save lives, Siddarth’s journey is only just beginning.
