Artificial intelligence better flags structural heart disease

The model’s score for distinguishing disease from no disease was 0.80, versus 0.75 for prediction using clinical information and standard heart-tracing findings.

Biomarkers
Studied:
Cross-sectional study of 3,779 adults undergoing public-system cardiovascular screening (Independent replication)
What changed:
AI scored 0.80 versus 0.75 for conventional prediction when distinguishing structural heart disease from no disease
The catch:
The AI correctly classified only 50.4% of people without disease as negative
Why it’s aging research:
It bears on staying healthy in midlife and later life.

Among 3,779 adults undergoing public-system cardiovascular screening in two Brazilian cities, a prospective observational study compared artificial intelligence (AI) screening with conventional prediction. Their median age was 66, and 56.7% were women. Participants had clinical assessments, electrocardiograms—recordings of the heart’s electrical activity—and heart ultrasound scans interpreted by cardiologists.

The AI analyzed the electrical recordings for structural heart disease, including heart muscle and valve problems. It distinguished disease from no disease better than prediction using clinical information and standard heart-tracing abnormalities. Ultrasound detected disease in 24.2% of participants. The AI identified 87.3% of those with disease but correctly classified only 50.4% of those without it as negative. Under fixed ultrasound capacity, AI-guided prioritization reduced the estimated time to diagnosing half the cases from 407 to 172 days.

Why it matters

Age was independently linked to structural heart disease in this screening population. The authors suggest AI may help underserved public health systems prioritize limited heart ultrasound appointments.

Caveats

The shorter diagnostic wait was an estimate based on fixed ultrasound capacity, not an observed reduction in waiting time. The findings came from adults attending public-system screening in two Brazilian cities.
