Hyperuricemia is reportedly associated with the progression of carotid intima-media thickness (IMT), a surrogate of cardiovascular risks and events. However, factors associated with carotid IMT progression in patients with asymptomatic hyperuricemia are largely unknown. In this post-hoc analysis of the multicenter, randomized PRIZE study, we analyzed data from a total of 326 patients who underwent carotid ultrasonography in a blind manner at baseline and 24 months to evaluate carotid IMT. Mean and maximum IMT at the common carotid artery (CCA) were measured at a central core laboratory. Factors related to the absolute change in mean and maximum IMT from baseline to 24 months were explored. Overall, the adjusted mean [0.0032 (- 0.0214 to 0.0278) mm] and maximum [0.0011 (- 0.0327 to 0.0351) mm] CCA-IMT increased numerically from baseline to 24 months. Multivariable analysis identified higher body mass index, history of atherosclerotic cardiovascular disease (ASCVD), and lower mean CCA-IMT at baseline as significant factors associated with the increase in mean CCA-IMT. In addition, older age and lower mean CCA-IMT at baseline were significant factors for an increased absolute change in the maximum CCA-IMT at 24 months. The present sub-analysis of the PRIZE study showed higher body mass index, history of ASCVD, and older age as significant factors associated with CCA-IMT progression in patients with asymptomatic hyperuricemia. These factors may be considered when identifying the possible risk of atherosclerotic progression in this specific patient population of hyperuricemia.Trial registration: UMIN000012911 and UMIN000041322.
