Factors influencing disease-related knowledge and health empowerment on health behavior compliance among patients after percutaneous coronary intervention in Korea: a cross-sectional study

Purpose: This study investigated the influence of disease-related knowledge and health empowerment on health behavior compliance among patients who underwent percutaneous coronary intervention.Methods: This descriptive correlational study involved 155 patients who underwent coronary intervention at a tertiary hospital. Data were collected using structured questionnaires measuring health behavior compliance, disease-related knowledge, and health empowerment from May to August 2024. Data were analyzed with descriptive statistics, the independent t-test, one-way analysis of variance, Pearson correlation coefficients, and multiple regression analysis using SPSS ver. 27.0.Results: Participants showed mean scores of 0.67±0.20 (out of 1) for disease-related knowledge, 3.25±0.99 (out of 5) for health empowerment, and 1.76±0.52 (out of 3) for health behavior compliance. Educational level (t=–5.05, P<0.001) and monthly income (F=11.90, P<0.001) showed significant differences according to health behavior compliance. Multiple regression analysis revealed that health empowerment (β=0.69, P<0.001) and disease-related knowledge (β=0.17, P=0.006) were significant predictors of health behavior compliance, explaining 65% of variance (F=57.50, P<0.001).Conclusion: These findings demonstrate that health empowerment and disease-related knowledge significantly affect health behavior compliance in post–coronary intervention patients. Healthcare providers should implement comprehensive interventions aimed at enhancing these factors to improve patient outcomes.
