Brief summary

This study aims to evaluate the effectiveness of Acceptance and Commitment Therapy (ACT) in improving both clinical and psychological wellbeing among patients with Pulmonary Arterial Hypertension (PAH) at the National Heart Institute, Malaysia. PAH affects not only physical health but also mental and emotional wellbeing, yet psychological aspects are often overlooked in treatment. By comparing ACT with standard care, this study hypothesize that ACT will lead to improved clinical and psychological outcomes.
