Insights
Depression after cardiac hospitalization can be predicted by three factors: prior emotional health issues, current smoking, and depression during the hospital stay. Many patients experience persistent depression for up to a year.
Area of Science:
- Cardiology
- Psychiatry
- Public Health
Background:
- Cardiac hospitalization presents a significant risk for developing or exacerbating depression.
- Understanding predictors of post-cardiac depression is crucial for timely intervention.
- The natural history of depression following cardiac events requires further elucidation.
Purpose of the Study:
- To identify clinical and demographic characteristics predicting depression 12 months post-cardiac hospitalization.
- To investigate the longitudinal course of depressive symptoms in cardiac patients.
Main Methods:
- A cohort of 785 patients was monitored for depressive symptoms using the Center for Epidemiological Studies Depression Scale at baseline, 3, and 12 months.
- Multinomial regression analysis was employed to identify predictors of 12-month depression from baseline variables.
Main Results:
- Depression during the index cardiac admission, a history of emotional health problems, and current smoking were significant predictors of moderate to severe depression at 12 months.
- Over half (51%) of patients depressed during hospitalization remained depressed at both 3 and 12 months.
- Persistence of depression was more pronounced in patients with moderate to severe depressive symptoms during hospitalization.
Conclusions:
- Three readily identifiable factors at hospitalization can predict 12-month depression risk in cardiac patients, aiding treatment decisions.
- A substantial proportion of cardiac patients experience persistent depressive symptoms up to one year post-hospitalization.
- Early identification and intervention for depression in cardiac patients are warranted.
Objective:
To determine characteristics which predict depression at 12 months after cardiac hospitalization, and track the natural history of depression.
Method:
Depressive symptoms were monitored at baseline, 3 and 12 months in a cohort of 785 patients, using the self-report Center for Epidemiological Studies Depression Scale. Multinomial regression analyses of baseline clinical and demographic variables identified characteristics associated with depression at 12 months.
Results:
Three baseline variables predicted moderate to severe depression at 12 months: depression during index admission, past history of emotional health problems and current smoking. For those who were depressed during cardiac hospitalization, 51% remained depressed at both 3 and 12 months. Persistence was more evident in patients who had moderate to severe depressive symptoms when hospitalized. Mild depression was as likely to persist as to remit.
Conclusions:
Three clinically accessible characteristics at the time of cardiac hospitalization can assist in predicting depression at 12 months and may aid treatment decisions. Depressive symptoms persist in a substantial proportion of cardiac patients up to 12 months after hospitalization.
