Impact of preoperative physical activity and depressive symptoms on post-cardiac surgical outcomes.

Objective: To determine the independent and combined impact of preoperative physical activity and depressive symptoms with hospital length of stay (HLOS), and postoperative re-hospitalization and mortality in cardiac surgery patients.

Methods: A cohort study including 405 elective and in-house urgent cardiac surgery patients were analyzed preoperatively. Physical activity was assessed with the International Physical Activity Questionnaire to categorize patients as active and inactive.

Impact of physical activity on depression after cardiac surgery.

Background: Physical activity is associated with a lower prevalence of depressive symptoms in cardiac patients. However, the benefits of physical activity on depression perioperatively are unknown. We sought to identify independent parameters associated with depression in patients undergoing cardiac surgery.

Depression before and after cardiac surgery: do all patients respond the same?

Objective: To characterize the prevalence, incidence, and risk factors for depression before and after cardiac surgery.

Methods: Patients awaiting nonemergent surgery (N = 436), completed the Patient Health Questionnaire-9 for depression, as well as the International Physical Activity Questionnaire short version preoperatively (Q1, n = 436) and at hospital discharge (Q2, n = 374). At baseline patients were categorized depression "naïve," "at risk," or "depressed.
