Since 2001 we have been collecting data on atherosclerosis
within the carotid arteries. This non-invasive test yields
graded scores for both the degree and type of atheroma.
This data has been correlated with the results of both coronary
angiography and CT scanning calcium scoring, as well as
routine risk factors.
Results so far show no useful correlation between standard risk
factors and the presence of atheroma. There is, however, a
highly significant correlation in the co-existence of carotid
and coronary artery atheroma (CAD). This result makes carotid
Ultrasound the single most powerful non-invasive (and non-
X-ray) test predicting the need for further cardiac
evaluation in the screening environment. In the clinical
evaluation of chest pain, the presence of carotid atheroma
substantially increases the likelihood of CAD. Of those with
proven CAD, 98% have significant carotid atheroma.
These results strongly suggest that carotid ultrasound scanning
be included as routine in the initial evaluation of patients
suspected of having CAD. It is of course unnecessary in the
presence of classical angina where angiography is the next
essential diagnostic step.
