The effects of video education on comfort and tolerability of patients undergoing coronary angiography

Coronary angiography is a definite diagnostic evaluation for coronary artery disease and valvular heart disease. It is necessary to provide information to such patients in order to maximize their comfort and tolerability to the invasive procedure. The study aimed at assessing the effect of patient's education by video on comfort and tolerability of patients undergoing coronary angiography. Using quasi- experimental method with a pretest-posttest design, 128 patients with coronary artery diseases randomly assigned to two groups of control and experiment. The sample hadn’t any experience of the procedure before. Control group received routine oral education by nurses and experimental group received an informative video on coronary angiography procedure as well as pre and post angiography interventions. Data were gathered through a 10-point rating visual analog scale (VAS) for comfort level and a 4-point rating scale to measure tolerability. No significant difference was found between the two groups, concerning demographic variables. It was revealed that the comfort level (P<0.001) and tolerability of the patient (P<0.05) in experimental group was higher than control group two, four and six hours after angiography (P<0.05). The study indicated providing information on angiography through video could enhance patients’ comfort and tolerability to the invasive procedure. It could result in shortened stay at hospital and increased satisfaction of patients
