    Abstract:
    AIMS: Carotid intima media thickness (IMT) is associated with an increased risk of cardio-vascular events, but its correlation with the absolute cardio-vascular risk is not well known in large populations. The Paroi Artérielle et Risque Cardio-vasculaire (PARC) study was designed to evaluate the relationship between conventional assessment of the global cardio-vascular risk by means of the Framimgham score and measurement of IMT of the common carotid artery (CCAIMT). METHODS AND RESULTS: About 246 French cardiologists selected 6416 subjects. CCAIMT measurements were performed using a specific methodology designed to harmonize the acquisition and processing of B-mode ultrasound images. The Framingham cardio-vascular score was determined for each individual. The relationship between CCAIMT and Framingham scores was evaluated using linear or polynomial models of regression. We found a significant correlation between CCAIMT and all components of the Framingham score (p < 0.005 for all parameters). The Framingham score and CCAIMT values were non-linearly related (coefficients of determination R2 were 19% and 20% in men, 28% and 29% in women, for subjects with and without personal history of cardio-vascular disease, respectively). The younger the subjects, the steeper the relationship, when the analysis was performed according to decades. CONCLUSIONS: The Framingham score and CCAIMT values were significantly correlated. However variations in CCAIMT only explained a modest part of the Framingham score and vice versa.
