Self-reported sleep quality and depression in post myocardial infarction patients attending cardiology outpatient clinics in Oman

摘要

Objective: This study aimed to examine the sleep quality and prevalence of depression in post myocardial infarction patients attending cardiology outpatient clinics of selected hospitals in Oman.Methods: A descriptive cross-sectional design was used to collect data from patients (n 180) who were at least 4 weeks post myocardial infarction diagnosis and receiving follow-up care in the outpatient clinic.The Arabic version of the Pittsburgh Sleep Quality Index and Patient Health Questionnaire-9 were used to assess sleep quality and depressive symptoms,respectively.Results: The sample mean age was 62.0 ± 11.3 years.Poor sleep quality affected 61.1% of the participants.The significant predictors of poor sleep quality were gender (P ≤ 0.05),body mass index (P ≤ 0.05),and self-reported regular exercise (P ≤ 0.01).The most impacted domains of sleep quality were sleep latency,sleep duration,and sleep disturbances.The prevalence of major depression was low (5%) and the rate of re-infarction was 27.2%.The prevalence of minimal to mild major depression with a potential of transitioning into major depression overtime was very high.Self-reported regular exercise (P ≤ 0.01) was the only significant predictor of depressive symptoms.Conclusion: The sleep quality of post myocardial infarction patients was poor and the prevalence of depression was low.There was no significant relationship between sleep quality or depression with reinfarction.
