Clinical Scorecard: Insomnia Prevalence and Contributing Factors in Coronary Heart Disease Patients: A Systematic Review and Meta-Analysis
At a Glance
Category
Detail
Condition
Insomnia in patients with coronary heart disease (CHD)
Key Mechanisms
Bidirectional relationship where CHD induces insomnia via sympathetic activation, inflammation, somatic symptoms, and psychological distress; insomnia exacerbates CHD by activating sympathetic nervous system and HPA axis, causing hemodynamic and metabolic disturbances and endothelial dysfunction
Target Population
Adult patients (≥18 years) with confirmed coronary heart disease
Care Setting
Outpatient and inpatient clinical settings excluding cardiac intensive care units
Key Highlights
Pooled prevalence of insomnia in CHD patients is 51.8% (95% CI: 44.6%–59.0%)
Significant risk factors for insomnia include female sex, anxiety, depression, CHD duration ≥3 years, diabetes, and gastritis
Insomnia contributes to worse cardiovascular outcomes and increased healthcare utilization in CHD patients
Guideline-Based Recommendations
Diagnosis
Screen for insomnia in all adult CHD patients using validated assessment tools
Exclude sleep-disordered breathing and other sleep disorders when diagnosing insomnia
Management
Prioritize early identification and intervention targeting modifiable risk factors such as anxiety, depression, diabetes, and gastritis
Focus on female patients and those with CHD duration ≥3 years for insomnia management
Monitoring & Follow-up
Regularly assess sleep quality and insomnia symptoms during CHD follow-up visits
Monitor psychological status and comorbid conditions that may influence insomnia
Risks
Recognize that untreated insomnia may worsen CHD prognosis by promoting sympathetic activation and endothelial dysfunction
Consider increased risk of adverse cardiovascular events associated with poor sleep quality
Patient & Prescribing Data
Adults with coronary heart disease experiencing insomnia
Interventions should address psychological comorbidities and metabolic conditions to improve insomnia and potentially reduce cardiovascular risk
Clinical Best Practices
Incorporate insomnia screening as a routine part of CHD patient assessment
Use multidisciplinary approaches including psychological and metabolic management to address insomnia
Educate patients on the impact of sleep health on cardiovascular outcomes
Tailor insomnia interventions considering patient sex and duration of CHD
