Summary
Depression is common following coronary heart disease (CHD) events, affecting 14-19% of patients. Smoking and poor New York Heart Association (NYHA) class are linked to higher depression rates, highlighting the need for integrated cardiac rehabilitation.
Area of Science:
- Cardiology
- Psychiatry
- Public Health
Background:
- Coronary heart disease (CHD) encompasses various cardiovascular events.
- Depression is a significant comorbidity affecting patient outcomes.
- Post-event mental health screening is crucial for cardiac patients.
Purpose of the Study:
- To determine the prevalence of depression at least six months after major CHD events.
- To investigate associations between depression and clinical variables in cardiac patients.
Main Methods:
- A cohort of 414 patients under 71 years old, who experienced CHD events, were interviewed and examined.
- Data collected included smoking habits, body mass index, lipid levels, diabetic status, and New York Heart Association (NYHA) functional class.
- Depression screening was performed using a self-rated depression scale.
Main Results:
- The prevalence of depression ranged from 14% to 19% across the four diagnostic categories of CHD.
- Depression was significantly associated with current smoking (OR 1.7, 95% CI 1.2; 2.4).
- Poor NYHA class was also strongly associated with depression (OR 1.9, 95% CI 1.4; 2.6).
Conclusions:
- Depression is a common condition following coronary heart disease events.
- Smoking and impaired functional capacity (NYHA class) are key risk factors for post-CHD depression.
- Integrating depression identification and treatment into cardiac rehabilitation programs is recommended.
