Over 20 years ago some Italian researchers stopped people in the street and took an ultrasound pictures of their neck arteries. They also took blood cholesterol tests and found that the ‘furring’ of arteries (a process called atherosclerosis, responsible for coronary heart disease) was in no way related to the blood cholesterol level.
At the Cardiac Centre our research has confirmed this but has also shown that neck artery scan also predicts the presence of coronary artery disease. Because this is a harmless and easily repeatable test it is very useful for both routine screening as well as the evaluation of preventative interventions such as exercise, diet and statin drug administration.
We are now in a position to say that any cardiac screening examination without a carotid artery (or other arterial ) scan is incomplete and lacks any useful predictive power.
