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

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. (C) 2019 Chinese Nursing Association. Production and hosting by Elsevier B.V.
