Ultrasound helps predict heart attacks in "low risk" patients

HOUSTON -- (November 10, 2008) -- By adding the results of an imaging technique to the traditional risk factors for coronary heart disease, doctors at Baylor College of Medicine in Houston found they were able to improve prediction of heart attacks in people previously considered low risk.

The findings are being presented today at the American Heart Association's Scientific Sessions in New Orleans.

Researchers used ultrasound imaging to view the carotid intima media thickness (C-IMT), or thickness of the artery walls.

"The ultrasound added another dimension to the risk factor score and showed us that those with thick arteries in the higher end of low risk group actually are at intermediate risk for coronary heart disease," said Dr. Vijay Nambi, assistant professor of medicine - atherosclerosis and vascular medicine at BCM and lead author of the study.
