Carotid ultrasound may help predict cardiac events

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.

Coronary Artery Calcium & Risk Classification/prediction

April 28, 2010 – The results for the Multi-ethnic Study of Atherosclerosis (MESA) have been published in the Journal of the American Medical Association.  Over 6,800 patients were screened – half using traditional risk factors such as age, gender, smoking history, blood pressure, cholesterol and ethnicity.  The other half were screened for traditional risk factors, plus received a Coronary Artery Calcium scoring test.

The study concluded that adding CACS to a prediction model “significantly improved” the classification of risk.

Did you know?  Risk factors such as high cholesterol, overweight etc do not tell you whether you have any biological evidence of early atherosclerosis.  Coronary Artery Calcium Scoring (CACS) and Carotid Intima-media thickness (CIMT) are two screening tests that can accurately measure actual changes within your body that indicate early atherosclerosis.
