Symptom networks were constructed using the R language. The constructed symptom network was structurally stable, and the correlation stability coefficient was 0.595. In the network, \u2018depression\u2019 (MLHFQ9), \u2018dyspnoea on exertion\u2019 (MLHFQ3), and \u2018worry\u2019 (MLHFQ7) are the core symptoms. \u2018Cognitive problems\u2019 (MLHFQ8), \u2018sleep difficulties\u2019 (MLHFQ4), and \u2018fatigue\u2019 (MLHFQ6) are bridge symptoms connecting the emotional-cognitive and somatic symptom clusters. In the network comparison test, there were no significant differences in symptom networks between patients of different genders and places of residence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>\u2018Depression\u2019 and \u2018increased need to rest\u2019 are the core and most severe symptoms, respectively, in the vulnerable phase of chronic heart failure, and \u2018cognitive problems\u2019 is the most important bridge symptom. Clinical caregivers can build a precise intervention programme based on the core and bridge symptoms and focus on the emotional and cognitive symptom clusters, in order to improve the efficacy of
