Abstract
Background: Ischemic heart disease stands as the foremost cause of death among cardiovascular conditions. The most commonly employed revascularization method for treating ischemic heart disease is percutaneous coronary intervention (PCI). An improvement in the patient's quality of life frequently serves as the primary measure of PCI's success. Objectives: The purpose of this study was to assess the impact of an educational program grounded in the information-motivation-behavioral skills (IMB) model on the quality of life of patients who have undergone PCI. Methods: This quasi-experimental study involved 84 patients selected from those referred to the Cardiovascular Clinic of Razi Hospital in Birjand city, located in eastern Khorasan. Participants were required to fill out a demographics form and the Short Form of the Quality-of-Life Questionnaire (SF-12). They were then divided into an intervention group (n = 42) and a control group (n = 42) through the use of the permuted block method. Those in the intervention group participated in a 6-week educational program (meeting once weekly) designed around the IMB model. The control group received the standard care available at the Cardiovascular Clinic. Both groups were asked to return to the Cardiology Clinic 6 weeks after the initial test to complete the SF-12 (posttest). All participants were surveyed again one month after the second questionnaire completion (follow-up). Results: The intervention group showed a significant increase in the mean score of physical health immediately and one month after the intervention, compared to the pretest scores (P = 0.001 and P = 0.004, respectively). Furthermore, the mean posttest score for psychological health in the intervention group significantly improved compared to the pretest (P < 0.001), and their follow-up score improved significantly compared to the posttest score (P = 0.02). There were no significant changes in the mean scores for physical and psychological health in the control group over time (P > 0.05). Conclusions: This study indicates that the quality of life for patients post-PCI can be significantly improved through participation in an educational program based on the IMB model. This research provides a foundation for the development of interventions with more enduring effects on post-PCI patient outcomes.
