Introduction: Functional impairments in coronary heart disease (CHD) patients can lead to care dependency and hinder secondary prevention efforts. Patients with low care dependency and high adherence to secondary prevention may see improvements in their quality of life.
Objectives: To explore the relationship between care dependence, adherence to secondary prevention, and quality of life in CHD patients receiving outpatient care.
Methods: This quantitative cross-sectional study involved 120 CHD patients selected using purposive sampling. Data were collected using the Care Dependency Scale, the Medical Outcomes Study Specific Adherence Scale, and the Seattle Angina Questionnaire-7, and analyzed using the Spearman correlation test.
Results: Most respondents with very low care dependence (92.5%) and high adherence (86.6%) reported a high quality of life. Significant correlations were found (p=0.001; r=0.307; 95%CI 0.17-0.42 for care dependence; p=0.020; r=0.212; 95%CI 0.02-0.38 for adherence), indicating a moderately positive relationship between care dependence, adherence to secondary prevention, and quality of life.
Conclusions: Care dependence and adherence to secondary prevention were significantly related to quality of life in CHD patients. Healthcare providers should focus on reducing care dependence and improving adherence to secondary prevention. Practical recommendations include patient-centered education, enhanced follow-up care, and tailored support systems to help patients manage their condition and improve their quality of life.
