Can a routine coronary calcium scan reveal more about a patient’s long-term cardiovascular risk?
A new HeartLung.AI study explores how AI-derived cardiac chamber measurements from routine coronary artery calcium (CAC) scans may help predict future atrial fibrillation and stroke.
Using data from the MESA and Framingham Heart Study cohorts, researchers evaluated AI-derived measures including:
Left Atrial Volume Index (LAVI)
LA/RA Volume Ratio
LA/LV Volume Ratio
The study examined their association with long-term atrial fibrillation and stroke outcomes, with follow-up extending up to 17 years.
The findings demonstrate the potential of AI to extract clinically meaningful cardiovascular information from CT scans originally acquired for coronary calcium assessment—expanding the value of an existing scan beyond its original purpose.
One scan. More insight. Greater opportunity for earlier risk assessment.
