Summary
Depression in coronary disease patients impacts revascularization needs and healthcare costs. Patients with depression utilized more procedures and incurred higher long-term costs.
Area of Science:
- Cardiology
- Psychiatry
- Health Services Research
Background:
- Depression is linked to increased cardiac events and functional decline in coronary disease patients.
- Understanding depression's effect on healthcare utilization is crucial for patient management.
Purpose of the Study:
- To investigate the impact of depression on subsequent healthcare utilization in patients with coronary disease.
Main Methods:
- 198 patients with stable coronary disease were assessed for depression (major, minor, none) post-angiography.
- Cardiac events, hospitalizations, procedures, and costs were tracked for 5 years.
Main Results:
- Depression status influenced revascularization procedures like coronary artery bypass grafting (CABG) and percutaneous transluminal coronary angioplasty (PTCA).
- While no significant differences in myocardial infarction or death rates were observed, depression groups showed varied procedural timelines.
- Patients without depression had higher initial costs, but depressed patients incurred greater costs in subsequent years.
Conclusions:
- Pre-existing depression at angiography is a significant predictor of revascularization needs.
- Depression status is associated with differential healthcare costs over a 5-year period following cardiac procedures.
