New AI Tool Detects 93% of Heart Disease in 10 Seconds

A simple 10-second heart scan may soon catch deadly disease before it's too late, thanks to breakthrough software that sees what human doctors cannot.

Researchers at Imperial College London have developed artificial intelligence that detects heart disease using standard electrocardiogram (ECG) tests. The tool spots patterns invisible to even expert cardiologists, turning a basic screening into a powerful diagnostic weapon.

Heart disease kills 20 million people worldwide each year. Currently, patients suspected of having the condition need echocardiograms, specialized scans that often require months-long waits. Many people's hearts deteriorate while they wait for answers.

The new software changes that equation entirely. It analyzes the electrical signals from a standard ECG and identifies heart disease with 93% accuracy, based on a trial involving 67,000 patients. Results were presented this week at the European Society of Cardiology annual congress in Munich, Germany.

"We looked at the ECGs to see if we could do things that are superhuman," said Dr. Arunashis Sau from Imperial College. "Not things that clinicians can already do, but things that no cardiologist, no matter how expert, can do."

The implications are staggering. ECG machines are already common in hospitals, clinics, and even ambulances. The software could be deployed widely without expensive new equipment, bringing advanced diagnosis to underserved areas.

Professor Fu Siong Ng, a cardiologist at Imperial, captured the significance: "A 10-second ECG, once a blunt screening tool, may soon become one of the most informative tests in medicine."

The Ripple Effect

The breakthrough arrives at a critical moment. Health systems worldwide struggle with diagnostic backlogs that grew during the pandemic and never fully cleared. This tool could help thousands of patients skip the wait for echocardiograms, getting treatment started while their hearts are still strong enough to respond.

Dr. Sonya Babu-Narayan, clinical director at the British Heart Foundation, put it simply: "When it comes to the heart, earlier diagnosis and treatment saves lives."

The technology represents a new frontier where artificial intelligence doesn't replace doctors but gives them superhuman abilities. It's the difference between waiting months in diagnostic limbo and starting life-saving treatment within days.

Researchers are now working toward wider implementation, potentially transforming how millions of people around the world are screened for the leading cause of death globally.
