Correlation analysis of electronic health literacy, compliance behavior, and quality of life in middle-aged and older patients with coronary heart disease: a cross-sectional study

Middle-aged and older CHD patients show low eHL, poor adherence, and moderate QOL. The findings of this study indicate the positive correlation between eHL, compliance behavior and QOL in middle-aged and older adults with CHD. These findings indicate that enhancing eHL can improve self-management and treatment adherence, thereby enhancing their overall QOL. Therefore, we recommend that medical institutions implement tailored intervention strategies for different patient groups to provide personalized health guidance aimed at comprehensively managing risk factors and promoting physical well-being.
