Implication

Cross-sectional study identifies key symptoms connecting sleep, anxiety, and depression in chronic heart failure, suggesting targeted interventions.

Key Points

  • This research aims to clarify the network connecting sleep quality, anxiety, and depressive symptoms among chronic heart failure patients.
  • Conducted a cross-sectional study with 406 patients diagnosed with chronic heart failure.
  • Participants completed questionnaires measuring sleep quality and mental health symptoms.
  • Used the Pittsburgh Sleep Quality Index to evaluate sleep quality and the Hospital Anxiety and Depression Scale for anxiety and depression assessment.
  • Employed Gaussian Graphical Models in R to analyze symptom interconnections.
  • The HADS12 and HADS13 symptoms showed the highest centrality in the network, indicating strong links to other symptoms.
  • Subjective sleep quality (PSQI-A) emerged as the key bridge symptom connecting sleep and psychological issues.
  • Targeting these central and bridge symptoms may enhance treatment outcomes for patients with chronic heart failure.
