Ethnic differences in the treatment of depression in patients with ischemic heart disease

Area of Science:

• Cardiology
• Psychiatry
• Health Disparities

Background:

• Coronary heart disease (CHD) is a leading cause of mortality in the US, disproportionately affecting African Americans.
• While traditional risk factors are more prevalent in African Americans, they don't fully explain the increased CHD mortality.
• Elevated depressive symptoms are linked to increased morbidity and mortality in patients with CHD.

Purpose of the Study:

• To investigate ethnic disparities in depressive symptoms and antidepressant treatment among patients undergoing diagnostic coronary angiography.
• To compare the prevalence and severity of depressive symptoms between white and African American patients with CHD.
• To determine if ethnic differences exist in the prescription of antidepressant medications for patients with CHD.

Main Methods:

• A cohort of 864 patients (727 white, 137 African American) undergoing diagnostic coronary angiography were studied.
• Depressive symptoms were assessed using the Beck Depression Inventory.
• Cardiovascular risk factors and medication data, including antidepressants, were collected via chart review.

Main Results:

• No significant difference was found in the severity of depressive symptoms between white and African American patients.
• The prevalence of elevated depressive symptoms was similar between African Americans (35%) and whites (27%).
• Antidepressant use was significantly lower in African Americans (11.7%) compared to whites (21%) (P = .016).

Conclusions:

• African Americans with CHD are less likely to be treated with antidepressant medications than whites, despite comparable depression levels.
• Ethnic differences in psychopharmacological management of depression indicate a need for improved depression assessment in African American CHD patients.
• Optimizing care for CHD patients requires addressing ethnic disparities in mental health treatment.
