Change in Depressive Symptoms During the First Month of Discharge and 1-Year Clinical Outcomes in Patients Hospitalized for Heart Failure.

Background The patterns of depressive symptom change during the first month after discharge, as well as their prognostic implications, and predictors of persistent or new-onset depressive symptoms are not well characterized. Methods and Results We included patients hospitalized for heart failure undergoing Patient Health Questionnaire-2 before discharge and at 1 month after discharge in a multicenter prospective cohort. We characterized 4 patterns of change in depressive symptoms-persistent, new-onset, remitted depressive symptoms, and no depressive symptom-and examined the associations between the 4 patterns and 1-year clinical outcomes. We analyzed the factors associated with persistent or new-onset depressive symptoms. A total of 4130 patients were included. Among 1175 (28.5%) symptomatic patients and 2955 (71.5%) symptom-free patients before discharge, 817 (69.5%) had remission, and 366 (12.2%) had new-onset depressive symptoms, respectively. Compared with no depressive symptom, persistent depressive symptoms were associated with an increased risk of cardiovascular death (hazard ratio [HR], 2.10 [95% CI, 1.59-2.79]) and heart failure rehospitalization (HR, 1.56 [95% CI, 1.30-1.87]); new-onset depressive symptoms were associated with an increased risk of cardiovascular death (HR, 1.78 [95%CI, 1.32-2.40]) and heart failure rehospitalization (HR, 1.54 [95% CI, 1.29-1.83]). Remitted depressive symptoms were associated with a slightly increased risk of cardiovascular death but had no significant association with heart failure rehospitalization. Patients who were female or had poor socioeconomic status, stroke history, renal dysfunction, or poor health status had a higher risk of persistent or new-onset depressive symptoms. Conclusions Sex, socioeconomic status, clinical characteristics, and health status help identify patients with high risks of depressive symptoms at 1 month after discharge. Dynamic capture of depressive symptom change during this period informs long-term risk stratifications and targets patients who require psychological interventions and social support to improve clinical outcomes.
