RESUMEN
Cardiac catheterization has been the most widely used diagnostic method, and in most cases, invasive diagnostic methods are associated with stress and concern that can affect the satisfaction and comfort of patients undergoing transradial coronary angiography. In this randomized controlled trial, a total of 89 patients undergoing transradial coronary angiography were recruited using convenience sampling. Then, the patients were assigned to two groups of intervention and control using blocked randomization, as those in the intervention group received video-based patient education and those in the control group received no training. Data were collected using the Persian version of the patient satisfaction questionnaire and the visual analog scale. The variables were measured before, 2, 4, and 8 hours after the angiography. The results indicated that, after the intervention, the mean scores of satisfaction and comfort in the intervention group were higher than in the control group (P < .001). Video-based educational strategies should be integrated into the nursing interventions to improve patients' health status.
