The aim of this study was to investigate the relationship between perceived stress with five major characteristics of the heart disease in patients with myocardial infarction. Materials and Methods: In this cross sectional descriptive-analytical study that was conducted from May 2005 till October 2009, a total of 3,200 patients with myocardial infarction, from cardiovascular care unit of Gha&#39;em and Imam Reza hospital, Mashhad, were randomly selected. A demographic questionnaire, an instrument for recording laboratory and electrocardiograph finding, and the Perceived Stress Scale were used for data collection. Results: The results of this study show that while 35% of all cases suffer from moderate stress, 65% percent of them suffer from high level of stress. The level of perceived stress in different categories of variables such as gender, educational level, hypertension, history of hypertension, depression, cigarette smoking, exercising, job, level of incoming, location of living, and family history of cardiovascular disease was significantly different from each other. Conclusion: Considering the high levels of stress among patients with myocardial infarction, design and implementation of interventions for identifying stressors, as well as their management seem to be crucial.</p> Keywords: Perceived stress, Cardiovascular disease, Myocardial infarction, Five characteristics of heart 100 112 http://journal.zums.ac.ir/browse.php?a_code=A-10-4-621&slc_lang=fa&sid=1 Amir Vahedian Azimi امیر واحدیان عظیمی vahedian63@zums.ac.ir 5200319475328460060016 5200319475328460060016 Yes Faculty of Nursing, Baqiyatallah University of Medical Sciences, Tehran, Iran Mostafa Sadeghi مصطفی صادقی 5200319475328460060017 5200319475328460060017 No Faculty of Medicine, Tehran University of Medical Sciences, Tehran, Iran Ali Movafegh علی موافق 5200319475328460060018 5200319475328460060018 No Faculty of Medicine, Tehran University of Medical Sciences, Tehran, Iran Rahim Sorouri Zanjani رحیم سروری زنجانی 5200319475328460060019 5200319475328460060019 No Zanjan University of Medical Sciences, Zanjan, Iran Davoud Hasani داود حسنی 5200319475328460060020 5200319475328460060020 No Zanjan University of Medical Sciences, Zanjan, Iran AR Salehmoghaddam امیر رضا صالح مقدم 5200319475328460060021 5200319475328460060021 No Faculty of Nursing & Midwifery, Mashhad University of Medical Sciences, Mashhad, Iran Mohammad Bagher Kashshsfi محمد باقر کشافی 5200319475328460060022 5200319475328460060022 No Faculty of Nursing & Midwifery, Mashhad University of Medical Sciences, Mashhad, Iran
