Abstract

Carotid intima-media thickness (c-IMT) is an intermediate phenotype not only for the local but also the global arteriosclerotic status, a concept which has been validated by its ability to act as a marker for future cardiovascular and cerebrovascular events. Whether the association between c-IMT and risk factors, distant atherosclerotic disease and prognosis are the sole prerogative of the carotid artery, or whether these findings can be extrapolated to other arterial sites is less well studied. In view of the concept of vascular heterogeneity, we measured the IMT in a muscular, lower extremity artery, the common femoral (f-IMT), and in elastic upper extremity artery, the common carotid, in apparently healthy individuals and explored the relationship with risk factors and the individuals 10-year cardiovascular (CV) risk, calculated using the Framingham systolic blood pressure equation. A population of 156 apparently healthy normotensive Caucasian volunteers between 18 and 65 years was studied (mean age 43+/-13 years; 68 men, 88 women; mean arterial blood pressure 126 +/- 15/70 +/- 10 mmHg). The c-IMT and f-IMT were measured using a 10 MHz vascular linear array transducer at the far walls 1 to 2 centimetres proximal to the right...Continue Reading
