Correlates of Sleep-related Disorders, Dream-related Factors, and Nightmares in Acute Myocardial Infarction Patients: Severity of Coronary Artery Stenosis, Chest Pain, and Somatic Symptoms
Journal Title: Journal of Turkish Sleep Medicine - Year 2020, Vol 7, Issue 3
Abstract
Objective: Sleep-related disorders and rapid eye movement-sleep parasomnias such as nightmares are among the threatening factors for the quality of life in clinical populations such as myocardial infarction (MI) patients. The present study was done to investigate the correlates of sleep-related disorders, dream-related factors, and nightmares in MI patients. Materials and Methods: In this cross-sectional study, 222 MI patients admitted to a hospital in western Iran participated in the study during June-December 2018. Patients completed several standard tools related to sleep and dream. The stenosis severity and extent were assessed using angiography by an expert cardiologist. Data were analyzed using the Pearson correlation coefficient and multiple regression analysis. Results: The mean (± standard deviation) age of patients (51.8% male) was 63.6±51.3. The prevalence of poor sleep quality was 98.2%. Somatic symptoms were strongest correlates of the poor sleep quality (p<0.001), sleep self-efficacy (p<0.001), nightmare frequency and severity (p<0.001), and emotionally negative dream (p=0.006). Chest pain and stenosis severity were unable to explain any of the sleep-related disorders or dream-related factors. Somatic symptoms (p<0.001) and chest pain (p=0.029) were lower in patients with fearful dream content compared to those without fearful content. Conclusion: Compared to the stenosis severity or chest pain, somatic symptoms are the strongest correlates of sleep-related disorders and dream-related factors included sleep self-efficacy and emotionally negative dream along with nightmare frequency and severity. Although, the relationship between somatic symptoms and fearful dream content is a complex phenomenon. Future longitudinal studies with several follow-up stages can provide valuable findings.
