About

This study aims to analyze the effect of Pulmonary Endarterectomy (PEA) on patients' self-confidence in managing their chronic illness.

Patients' confidence (or self-efficacy) will be measured using the following questionnaires: 10-item Perceived Efficacy in Patient-Physician Interaction Scale (PEPPI), Self-Efficacy for Managing Chronic Diseases 6-item Scale (SEMCD-6), Sullivan's cardiac self-efficacy scale 13-items (SCSES). The association between improved confidence and better physical results will be analyzed, such as being able to walk longer (6 mint walk test (6-Minute Walk Test)).

Ultimately, this study will help understanding the psychological side of recovery and might lead to better support programs to help patients feel more capable and live better lives after their operation.

Full description

This study specifically focuses on three key domains of self-efficacy relevant to the cardiac patient:

1. Patient-Physician Interaction (PEPPI): Confidence in communication with healthcare providers, which is vital for navigating the complexity of post-operative care, medication management, and identifying emergent issues.
2. Chronic Disease Management (SEMCD-6): Confidence in performing essential self-care tasks, such as managing symptoms, coping with emotional distress, and maintaining a healthy lifestyle.
3. Sullivan's cardiac self-efficacy scale 13-items (SCSES): it focuses on two dimensions: controlling symptoms and maintaining daily function We hypothesize that the successful physical removal of the disease burden via PEA will act as a major "mastery experience," fundamentally boosting a patient's self-efficacy. This improvement is expected to be immediately following the clinical stabilization and persist during follow-up, facilitating better long-term outcomes.

Study Rationale and Novelty

Current literature on CTEPH and PEA is heavily focused on the physiological and hemodynamic aspects of the disease. There is a significant gap in the understanding of the patient-reported psychological factors that contribute to excellent outcomes. This prospective cohort study is unique because:

• It is the first, to our knowledge, to specifically and longitudinally quantify the change in cardiac self-efficacy in patients undergoing PEA.
• It directly links this psychological change to the objective measure of surgical success (change in 6MWT), addressing the secondary objective of determining the correlation between psychological and physiological improvement.
• By using Multiple Linear Regression, the study will identify specific pre-operative baseline factors (e.g., 6MWT) that may predict which patients are most likely to experience a significant post-operative self-efficacy gain or remain at risk for low self-efficacy. This has direct implications for identifying patients who would benefit most from targeted pre-operative psychological support or post-operative rehabilitation strategies.

Expected Impact The findings of this study will contribute significantly to the holistic management of CTEPH patients. If a robust correlation is found between the magnitude of self-efficacy change and improved clinical outcomes or reduced readmission rates, it will provide strong evidence to support the integration of self-efficacy-focused interventions into post-PEA cardiac rehabilitation programs. Ultimately, understanding and bolstering the patient's belief in their ability to manage their condition post-surgery will not only optimize the clinical gains achieved by the PEA but also enhance long-term quality of life and reduce the burden on the healthcare system.
