Postoperative cardiac rehabilitation can improve patient outcomes; however, kinesiophobia and fear of progression are associated with lower adherence to rehabilitation. This study aimed to identify core symptoms within the fear network, explore hypothesized directional relationships among symptoms, and analyze the associations between the two types of fear symptoms and adherence to cardiac rehabilitation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a cross-sectional survey of 294 patients who underwent their first CABG at three tertiary hospitals in Urumqi, Xinjiang, between October 2025 and February 2026. Participants were assessed using the scale of adherence to cardiac rehabilitation, the scale to measure fear of activity in patients with coronary artery disease, and the fear of progression questionnaire-short form. R software was employed to construct the symptom network. Bayesian network analysis was used to construct a directed acyclic graph, and flow network analysis was applied to examine the associations between symptoms and cardiac rehabilitation adherence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In the symptom network, \u201cMy body does not allow me to do certain activities even though I would like to,\u201d \u201cBeing afraid of no longer being able to pursue hobbies,\u201d and \u201cBeing afraid of relying on strangers for activities of daily living\u201d were identified as central symptoms, while \u201cBeing afraid of pain\u201d and \u201cHaving physical symptoms, e.g., rapid heartbeat, stomachache, nervousness\u201d served as bridge symptoms. In the Bayesian network, \u201cBeing afraid of no longer being able to pursue hobbies\u201d was located at the apex of the network. In the flow network, a total of 19 symptoms showed negative associations with cardiac rehabilitation adherence, among which \u201cBeing afraid of pain,\u201d \u201cI am afraid of any physical activity since I learned my heart problem,\u201d and \u201cMy body does not allow me to do certain activities even though I would like to\u201d exhibited strong negative correlations.
