Inoue H, et al. – This study aimed at delineating the impact of trajectories of abdominal aortic calcification over 2 years on subsequent mortality. Data demonstrated a higher risk of death in chronic hemodialysis patients with a trajectory of longitudinal high or rapid accumulation of vascular calcification over time. As compared to one–time assessment, individual trajectories of vascular calcification seemed to allow for more accurate mortality risk calculations.
