| Learning Objective #1: Examine the change in sleep disturbance over time during the first six weeks of recovery after myocardial infarction (MI) | |||
| Learning Objective #2: Determine to what extent do the dose of beta-blocker therapy, anxiety and depression levels, demographic varibles contribute to the change in sleep disturbance after MI |
Design: A prospective, descriptive repeated measures design was used.
Sample: A convenience sample of 60 individual (mean age 54 years) with first time MI participated in the study.
Methods: Investigator interviewed the subjects face-to-face three times: third day of admission and two and six weeks after discharge.
Findings: Sleep disturbance significantly decreased over time. The main effect of time on sleep disturbance was significant, F (2,1) = 17.2, p < 0.00, however, the decrease did not remain when controlling for the selected covariates, suggesting that sleep disturbance is influenced by these covariates.
Conclusion: Findings of the study showed that sleep disturbance was significantly declined during the early recovery period.
Implications: Developing practice guidelines and home-going discharge protocols should include specific approaches that take into account contextual factors. Treating at-risk patients with early interventions may be useful.
