Abstract Background & Objectives: Coronary angiography is the standard method for the diagnosis of coronary artery disease. One of the main causes of pain in patients after coronary angiography is prolonged bed rest with no position change. Therefore suitable position cause reduces patient's pain. The aim of this study was to investigate the effects of changing the angle of the bed on patient's pain after coronary angiography. Material & Methods: This study is a randomized clinical trial. The sample consisted of all patients who admitted in angiography center of Imam Ali hospital, Bojnurd. Non-emergency coronary angiography was performed through the femoral artery. After angiography the bed angles were set on 0, 15, 30, 45 and 60 degrees. Pain was measured on a numeric scale of pain. The patient's temperature and blood oxygen saturation were also measured. Gender, age, height, history of previous coronary angiography was evaluated by questionnaire. Data were evaluated by using descriptive statistics, ANOVA, post hoc tests and estimated equation was analyzed by SPSS 16 and MATLAB 2011. Results: The results of this study show that there is no significant relationship between demographic factors and angle changes (p>0.05), while between various bed angles of the bed and the average pain was significantly changed (p<0.05). There is no significant relationship between temperature and oxygen saturation (p>0.05). Among of different angles, angle 45 degree is the best angle for the least amount of pain. Conclusion: This study shows that angle 45 degree is the best situation for decreasing pain after coronary angiography. According to results, this angle is recommended for medical and nursing care.
