To systematically evaluate the prevalence of insomnia and its influencing factors in patients with coronary heart disease (CHD) to inform clinical practice.
Key Findings:
Overall pooled prevalence of insomnia in CHD patients was 51.8% (95% CI: 0.446–0.590, P < 0.001) from 19 studies involving 5928 patients.
Significant risk factors for insomnia included female sex (OR = 2.00), anxiety (OR = 1.61), depression (OR = 2.15), CHD duration ≥3 years (OR = 1.73), diabetes (OR = 1.50), and gastritis (OR = 2.24).
Interpretation:
Insomnia is highly prevalent among CHD patients, with specific demographic and clinical factors influencing its occurrence.
Limitations:
Variability in insomnia assessment tools across studies may affect prevalence estimates and complicate comparisons.
Limited data on the influence of age and other demographic characteristics on insomnia prevalence.
Conclusion:
Clinicians should prioritize early identification and intervention for insomnia in CHD patients, particularly focusing on modifiable risk factors such as anxiety, depression, diabetes, and gastritis.
