[Noninvasive assessment of morphology and function of the great vessels].
Hypertension is well recognized as a risk factor that is associated with an increased incidence of stroke and myocardial infarction. The early detection of atherosclerosis is a real challenge and should be carried on at a cost and with a degree of risk and invasiveness that does not preclude its use in subjects with cardiovascular risk factors. For this purpose we have developed a non-invasive approach using a high resolution echotracking device making it possible to measure internal diameter and wall thickness of conduit arteries as well as their biomechanical properties. We present here a methodological overview of the system with a brief clinical study addressing the biomechanical properties of a medium size artery in hypertension as compared with normotension.
