Pak J Med Sci Jan ;25(5):901-5.

Objective: Anxiety and stress are common in patients undergoing invasive procedures. Coronary angiography is a definitive diagnostic evaluation for coronary artery disease and valvular disease. It is necessary to give information to the patients in order to minimize levels of anxiety and stress to this invasive procedure. The aim of this study was to evaluate the effect of patients’ education by video on levels of anxiety, stress and depression of patients undergoing coronary angiography. Methodology: In a quasi-experimental, pretest-posttest design, 128 patients were randomly assigned to either control or experimental group. Control group received verbal routine education by nurses and experimental group received an informative video about coronary angiography procedure as well as pre and post angiography interventions. Using Depression, Anxiety, Stress Scale (DASS-21) levels of these variables were measured before and after education. Results: Seventy eight (60.9%) males and fifty (39.1%) females participated in the study. There was a statistically significant reduction in the Anxiety, stress and depression levels of experimental group after video information (P= .000). There was a statistically significant correlation between sex with anxiety (P= .000) and stress (P= .04). Conclusions: The use of patients’ education by informative video is a useful method for decreasing psychological parameters of patients undergoing coronary angiography procedure. Results of the study confirm the usefulness of video information prior to an Invasive angiography procedure.
