Rates of depression and anxiety in cardiac surgery patients are higher than in the general population. The development of persistent post-surgical pain (PPSP) in this population is also concerning. The objectives of this study were to (1) identify anxiety and depression trajectories of cardiac surgery patients over a 2-year period; (2) examine demographic and clinical characteristics associated with trajectory memberships and (3) determine if anxiety and/or depression trajectories predict PPSP. ⋯ This article presents the relationship between anxiety and depression profiles over 2 years in cardiac surgery patients and persistent post-surgical pain. These results suggest the importance of evaluating how early identification and treatment of high-risk patients could prevent PPSP. These results provide potential detection and prevention avenues of chronic pain for high-risk patients based on their anxiety trajectory.
