Patients undergoing coronary angiography often experience anxiety both before and during the procedure, often treated by the administration of anti-anxiety medications. A new analysis being presented at the American College of Cardiology (ACC) Middle East 2025 Together with 16th Emirates Cardiac Society Conference found virtual reality (VR) effectively reduced anxiety during the procedure and had more stable vital signs than patients receiving standard care.
Virtual reality offers an innovative solution to manage and reduce the anxiety of patients undergoing an interventional cardiovascular procedure, like coronary angiography, that they are typically awake during.”

Coronary angiography is part of a group of cardiac tests known as cardiac catheterization, which utilizes catheters to determine blockages and/or place stents in the vessels of the heart. Coronary angiography uses X-rays during the procedure to see if the blood vessel is narrowed or blocked during the diagnosis of coronary artery disease. In coronary angiography, the standard of care is to provide anti-anxiety medications to the patient before and during the procedure.
Virtual reality is a computer simulation that enables a person to interact with computer-generated 3-D visuals or other sensory environments.
Researchers analyzed data from five randomized controlled trials comprising 451 patients comparing VR to standard of care in patients undergoing coronary angiography. Some of the VR scenarios used included nature scenes like waterfalls, mountains and valleys, designed to induce a state of relaxation that may reduce anxiety and stabilize vital signs in these patients, Alnomani said. VR during coronary angiography was found to be superior to the standard of care in reducing anxiety and was associated with significantly lower changes in heart rate and blood pressure. While VR before coronary angiography did reduce anxiety, it did not show efficacy.
“Immersing patients in a 3D simulation offers better relaxation than just watching a similar video on a screen,” Alnomani said.
Limitations of the study include its retrospective nature. Larger, randomized controlled trials are needed in the future to determine the broad use of VR in improving care of patients undergoing coronary angiography and other cardiovascular interventions.
