April 8, 2010 – Performing ultrasound studies of carotid intima-media thickness (CIMT) provides long-term prognostic value for adverse cardiac events, giving doctors important clues about who is at risk for a heart attack.
Researchers from Baylor College of Medicine in Houston examined the carotid arteries of 13,145 patients and found that about 23% of patients would be reclassified into a different risk group by adding information obtained from ultrasound assessment of CIMT to traditional risk factors used for predicting future cardiac events. Risk prediction using this approach was more accurate, and it could help better define which patients should be screened with CIMT ultrasound.
“Noninvasive ultrasound can give us a more complete snapshot of our patients’ risk, so we can do a better job determining if they’ll have a heart attack,” added study co-author Dr. Christie Ballantyne.
