Key result
Poor self-care is linked to ~4-fold higher odds of poor quality of life in CAD.
Why the study?
Empirical evidence integrating disease-specific self-care assessment and symptom-based quality of life measurement in Indonesian CAD populations remains limited.
Cross-Sectional (n=50)
No
Odds Ratio: 4.125 (95% CI 1.235–13.782)
p-value: p=0.038
Good self-care behaviors are significantly associated with better patient-reported quality of life in outpatients with symptomatic coronary artery disease.
Supports self-care assessment in CAD outpatients; leaves open whether interventions improve quality of life in prospective trials.
Background: Coronary artery disease not only contributes to high mortality but also substantially impairs quality of life. Although self-care is recognized as a key component of chronic disease management, empirical evidence integrating disease-specific self-care assessment and symptom-based quality of life measurement in Indonesian populations remains limited. Methods: This analytical observational study employed a cross-sectional design involving 50 outpatients with CAD at Siloam Lippo Village Hospital (June–September 2023). Self-care was assessed using the Self-Care of Coronary Heart Disease Inventory (SC-CHDI), while quality of life was measured using the Seattle Angina Questionnaire (SAQ). Data were analyzed using the Chi-square test with a significance level of p<0.05. Result: A total of 60% of participants demonstrated good self-care and quality of life. A significant association was observed between self-care and quality of life (p=0.038; OR=4.125; 95% CI: 1.235–13.782). Clinical factors including hypertension (p=0.007), diabetes mellitus (p<0.001), and angina severity grade (p=0.002) were also significantly associated with quality of life. Conclusion: Self-care is a key determinant of quality of life in patients with CAD. Notably, the use of disease-specific instruments (SC-CHDI and SAQ) provided a more sensitive and clinically relevant assessment of the relationship between self-care behaviors and patient-reported outcomes, supporting the implementation of patient-centered care strategies in clinical practice.

Ng et al. (2026) conducted a cross-sectional in Coronary Artery Disease (n=50). Poor self-care vs. Good self-care was evaluated on Poor quality of life (OR 4.125, 95% CI 1.235-13.782, p=0.038). Poor self-care was significantly associated with a 4.125 times greater odds of having a poor quality of life compared to good self-care in patients with coronary artery disease.
