What is the clinical evidence from this study?

Study design: Cross-Sectional. Population: Coronary heart disease after percutaneous coronary intervention (PCI) (n=404). Intervention: Self-efficacy vs. Lower self-efficacy. Primary outcome: Membership in the high literacy–high coping capacity group (OR 23.441, 95% CI 11.244-48.868, p=<0.001).

What does this research mean for the field?

Higher self-efficacy is strongly associated with membership in the high health literacy–high coping capacity profile among older patients after percutaneous coronary intervention. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To identify latent profiles of health literacy among older patients with coronary heart disease following percutaneous coronary intervention and determine factors influencing profile membership.

Key result

Higher self-efficacy links to ~23-fold greater odds of high health literacy and coping capacity post-PCI.

Implication

Health literacy heterogeneity in older post-PCI patients warrants targeted assessment; leaves open optimal intervention strategies.

Key Points

To identify latent profiles of health literacy among older patients with coronary heart disease following percutaneous coronary intervention and determine factors influencing profile membership.
Conducted a cross-sectional study using convenience sampling of 404 older patients (≥ 60 years) who underwent percutaneous coronary intervention across three tertiary hospitals in Shanghai between May 2024 and December 2025.
Assessed participants using the Health Literacy Management Scale, Social Support Rating Scale, and Chronic Disease Self-Efficacy Scale.
Identified distinct subgroups using latent profile analysis in Mplus 8.3 and evaluated predictors via univariate analysis and multinomial logistic regression in SPSS 25.0.
Identified three distinct health literacy latent profiles: low literacy–strong intention, moderate literacy, and high literacy–high coping capacity.
Multinomial logistic regression revealed that self-efficacy, average monthly household income, family support, and marital status were significant independent predictors of profile membership (P < 0.05).

Population

404 older adults (aged ≥60 years) who had undergone percutaneous coronary intervention were assessed to identify latent profiles of health literacy and their associated factors.

Outcome

Latent profiles of health literacy and factors associated with profile membership (measured using Health Literacy Management Scale, Social Support Rating Scale, and Chronic Disease Self-Efficacy Scale)patient reported

Main Result

Odds Ratio: 23.441 (95% CI 11.244–48.868)

p-value: p=<0.001

Health literacy among older patients after PCI shows significant heterogeneity, and stratified interventions targeting different profiles based on self-efficacy, family support, economic resources, and marital status may improve cardiac rehabilitation outcomes.

Limitations

Only measured health insurance coverage at the policy environment level, missing other systemic factors like healthcare system complexity and accessibility.
Use of convenience sampling may limit the generalizability of the findings.
Cross-sectional design prevents the establishment of causal relationships between predictors and health literacy profiles.

Wang et al. (2026) conducted a cross-sectional in Coronary heart disease after percutaneous coronary intervention (PCI) (n=404). Self-efficacy vs. Lower self-efficacy was evaluated on Membership in the high literacy–high coping capacity group (OR 23.441, 95% CI 11.244-48.868, p=<0.001). Higher self-efficacy was strongly associated with membership in the high health literacy–high coping capacity group among older patients after PCI (OR 23.441).
