Self-Efficacy and Health Status in Patients With Coronary Heart Disease: Findings From the Heart and Soul Study
Why the study?
Does lower cardiac self-efficacy predict worse health status in outpatients with stable coronary heart disease?
Population

Implication
Low self-efficacy may flag higher symptom burden in stable CHD; hypothesis-generating for interventions, requiring prospective trials before practice change.
Key Points
- To explore the link between cardiac self-efficacy and health status in outpatients with coronary heart disease.
- Cross-sectional analysis of 1024 outpatients with coronary heart disease from the Heart and Soul Study.
- Administered measures for cardiac self-efficacy, depressive symptoms, and health status outcomes.
- Assessed cardiac function through exercise treadmill testing and stress echocardiography.
- Each 4.5-point decrease in self-efficacy score was associated with increased symptom burden (OR = 2.1, p = .001).
- Lower self-efficacy was linked with greater physical limitations (OR = 1.8, p < .0001) and worse quality of life (OR = 1.6, p < .0001).
- Worse overall health was related to lower self-efficacy (OR = 1.9, p < .0001).
Structured PICO

P
Population
1024 outpatients with stable coronary heart disease (CHD)
I
Intervention
Cardiac self-efficacy (measured by a validated measure)
O
Outcome
Health status outcomes including symptom burden, physical limitation, quality of life (assessed using the Seattle Angina Questionnaire), and overall healthpatient reported
Low cardiac self-efficacy is independently associated with worse health status, symptom burden, and physical limitation in patients with stable coronary heart disease.
