Insights
Major depression is more common in acute myocardial infarction survivors than the general population. Early diagnosis and treatment of depression may reduce coronary risk factors.
Area of Science:
- Cardiology
- Psychiatry
- Epidemiology
Context:
- Major depression is frequently associated with ischemic heart disease.
- This condition is often underdiagnosed and undertreated.
- Understanding depression prevalence post-myocardial infarction is crucial.
Purpose:
- To determine the prevalence of major depression in patients who survived an acute myocardial infarction.
- To compare depression rates in myocardial infarction survivors with a healthy control group.
Summary:
- A retrospective study analyzed 42 acute myocardial infarction survivors in Chile.
- Major depression was diagnosed in 12 patients using the CIDI and DIS instruments based on DSM-III-R criteria.
- Depression prevalence was significantly higher (p < 0.049) than in 156 healthy controls.
Impact:
- Acute myocardial infarction patients exhibit a significantly higher prevalence of major depression.
- Major depression may represent an independent and modifiable risk factor for coronary heart disease.
- This highlights the importance of screening for and managing depression in cardiac patients.
Background:
Major depression, a frequent psychiatric disease, is associated with ischemic heart disease. It is usually subdiagnosed and subtreated.
Aim:
To study the prevalence of major depression among survivors of an acute myocardial infarction.
Patients And Methods:
Retrospective study of 42 survivors of an acute myocardial infarction treated at a regional Chilean Hospital. The presence of major depression in the 6 months previous to the acute myocardial infarction, was investigated using the diagnostic instruments CIDI (Composite International Diagnostic Interview) and DIS (Diagnostic Interview Schedule), psychiatric diagnoses were based on DSMIII-R. The prevalence of depression was compared with that observed in a group of 156 healthy subjects participating in a psychiatric epidemiological study.
Results:
Major depression was diagnosed in 12 male subjects with an acute myocardial infarction. The prevalence in the control group was significantly lower (15%, p < 0.049). Patients with depression were older and required longer hospital stay than patients without depression.
Conclusions:
Patients with acute myocardial infarction, had a significantly greater prevalence of major depression in the previous 6 months, than the general population. Thus, major depression could be an independent and modifiable coronary risk factor.
