Chronic cardiovascular diseases (CVD) represent a growing global health burden, where therapeutic compliance is critical for effective disease management and prevention of complications. Mobile health (mHealth) applications have emerged as promising tools to support patients in managing chronic conditions, yet their adoption remains inconsistent. Existing technology adoption models often fail to fully capture the psychological dimensions that influence patient decisions. This study addresses this gap by investigating how health beliefs shape the adoption of mHealth applications for therapeutic compliance among chronic CVD patients. The research integrates the Health Belief Model (HBM) and the Technology Readiness and Acceptance Model (TRAM) to explore both psychological health beliefs and technology readiness traits in tandem. The study adopts a qualitative, exploratory design, employing semi-structured interviews with 11 CVD patients in the long-term management phase. Thematic analysis, supported by ATLAS.ti, was used to develop three key themes from participant narratives.
