Developing and Implementing a Hospital‑based Family‑centered Health Approach for Patients Undergoing Percutaneous Coronary Intervention: A Randomized Controlled Trial

Objectives: This study aimed to assess the effectiveness of a family-centered health program in promoting healthier lifestyles and improving self-care behavior among patients who had undergone percutaneous coronary intervention. We hypothesized that the family-centered health program would significantly enhance self-care and health-promoting lifestyle in this patient population. The current study was conducted to investigate the effectiveness of the family-centered health program on health- promoting lifestyle and self-care behavior in post-percutaneous coronary intervention patients. Materials and Methods: A randomized controlled clinical trial was conducted from October 2021 to March 2022 at the Shaheed Rajaie Cardiovascular, Medical & Research Center in Tehran. The study population included patients aged 40 to 65 who had undergone percutaneous coronary intervention. Sixty eligible participants were selected through purposive sampling and randomly assigned to either an experimental group that underwent the family-centered health program (n=30) or a control group (n=30). Data were collected using a demographic information questionnaire, Walker's health-promoting lifestyle questionnaire (1987), and Miller's self-care behavior questionnaire (1982) at three time points: baseline, post- intervention, and three-month follow-up. The intervention's effectiveness was assessed using variance analysis with repeated measurements in SPSS-21 software. Results: Preliminary analyses revealed no significant differences between the groups in self-care, health-promoting lifestyle, or blood pressures, indicating the two groups were homogeneous at baseline. However, post-test comparisons revealed significant differences, suggesting the family-centered health program was effective (P < 0.001). Conclusions: Given the demonstrated effectiveness of the family-centered health program, prioritizing such interventions could significantly improve secondary prevention outcomes in patients surviving coronary heart disease
