ارتباط بین افسردگی مرگ با افسردگی قلب در مددجویان مبتلا به سندروم حاد کرونری

Abstract Background and Objectives: Depression is the most psychological reaction in patients with acute myocardial infraction that can affect the sleep quality in these patients. Regarding that adequate sleep has important effect on working of heart; this study was conducted with the aim of assessment of correlation between sleep quality with death and cardiac depression in patient with Acute Myocardial Infarction (AMI). Methods: In this descriptive-correlational study, 407 CCU inpatient with acute myocardial infarction were recruited from Fatemeh Zahra educational hospital (Sari, Iran) with simple random sampling method. Data were gathered by Cardiac Depression Scale (CDS), Death Depression Scale (DDS) and Pittsburgh Sleep Quality Index (PSQI). In order to descriptive and inferential (multiple linear regression) analyses of data, SPSS 23.0 (SPSS Inc., Chicago, IL, USA) was used. Results: The mean age of male patients (64.95±17.00; CI95: 62.71-67.19) was more than the mean age of women (62.22±15.48; CI95: 59.96-64.48). Mean score of death depression (68.94±17.24; CI95: 67.26-70.62) and cardiac depression (109.00±16.49; CI95: 107.39-110.60) were under the fifth percentile. Multivariate regression analysis showed that changes in rate of cardiac depression (B=0.036, β=0.153), increasing educational levels (B=1.55, β=-0.121), and no history of antidepressant usages (B=4.32, β=0.123) can be significantly the independent predictive factors of variance score of sleep quality in acute myocardial infarction patients. Conclusion: Although cardiac depression, educational level and non-use of antidepressant drugs are considered as affecting factors in predicting the sleep quality in acute myocardial infarction patients, sleep quality is affected by more factors. So, further research is needed to be investigated. Keywords: Cardiac depression, Death depression, Sleep quality, Acute Myocardial Infarction, Iran
