OBJECTIVES: This study analyzed cross-sectional data to examine the prevalence of insomnia and to identify factors associated with insomnia after a myocardial infarction (MI).
METHODS: The participants were 209 individuals with a recent MI. At approximately 5 weeks post-MI, participants completed standardized self-report measures assessing insomnia (Insomnia Severity Index) and various sociodemographic, clinical, behavioral, and psychosocial variables, including stressful life events, depressive symptoms, and dysfunctional beliefs about sleep.
RESULTS: Overall, 36% of the sample reported clinical symptoms of insomnia (Insomnia Severity Index score ≥ 10) and an additional 9% reported milder/subthreshold symptoms (Insomnia Severity Index score ≥ 8). Among patients with insomnia, a much higher proportion (62.7%) were experiencing symptoms consistent with depressed mood compared to good sleepers (13.4%). Multivariate linear regression showed that younger age, use of prescribed medication for sleep, more depressive symptoms, and greater dysfunctional beliefs about sleep were associated with insomnia severity.
CONCLUSIONS: Many patients after MI experience insomnia, which may increase the illness burden and hamper recovery during the cardiac rehabilitation phase. Our findings provide a theoretical basis for evaluating cognitive-behavioral approaches for the management of insomnia in patients after MI.
