Myocardial revascularization surgery is still the most used in the treatment of many coronary artery diseases in an attempt to improve patient survival. In the preoperative period, anxiety can appear as a precursor of unwanted responses before surgery and worsen the postoperative prognosis. Thus, a non-pharmacological method to reduce this negative feeling and assist in the patient's surgical process is nursing guidance, which serves in the acquisition of knowledge within health education and can rely on technological tools to facilitate communication and bring reality closer. of the patient. In this sense, the objective is to evaluate the effectiveness of using video to acquire knowledge and reduce the level of anxiety in the preoperative period of myocardial revascularization. This is a randomized controlled clinical trial, carried out in the cardiology ward of Hospital Rio Grande, with 52 patients undergoing coronary artery bypass graft surgery, equally divided into Control Group and Experimental Group, which received guidance with the audiovisual resource of a video, while the Control Group received only the institution's standard guidelines. For data collection, the first researcher applied the instrument to assess the patient's anxiety before interventions both groups, in the second moment, the main researcher performed the different interventions for the two groups, and, finally, the first researcher returned to apply the anxiety assessment instrument again – now after the interventions – and the instrument to assess the knowledge acquired, without knowing which patient is part of each group. This project was approved by the Central Research Ethics Committee of the Federal University of Rio Grande do Norte No. CAAE 40743520.9.0000.5537 and registered in the Brazilian Registry of Clinical Trials (RBR-24c5qwm). The patients had a mean age of 63 years and the majority had completed elementary school. It was possible to prove that the audiovisual resource of the video was significant in increasing the patient's knowledge about the surgical procedure. In the control and experimental groups, it was observed that both interventions increased patients' confidence in the operation, proving that nursing guidelines help the patient in this perioperative period. Thus, the study reinforces that audiovisual tools can help in nursing guidance, providing further explanations and increasing patient education about their health condition. This study proves the importance of nurses in interventions in the preoperative period and contributes to a better patient experience in terms of surgery.
