Virtual Reality During Coronary Angiography: Effects on Pain and Anxiety (VR-CAPA)

March 16, 2026 updated by: Meryem Ayvaz, Koç University

Beyond the Cath Lab Curtain: Virtual Reality's Impact on Pain and Anxiety: A Randomized Controlled Trial

This study investigated whether virtual reality (VR) can reduce pain and anxiety in patients undergoing coronary angiography. Coronary angiography is a common cardiac procedure performed under local anesthesia while patients remain awake, which can cause significant pain and anxiety.

Adult patients scheduled for elective coronary angiography were randomly assigned to two groups: one group watched a nature-themed VR video during the procedure, while the control group received standard care. Pain and anxiety levels were measured before and after the procedure using validated scales.

The findings of this study may help healthcare providers offer a simple, non-pharmacological method to improve patient comfort during coronary angiography.

Detailed Description

Coronary angiography is one of the most frequently performed invasive cardiac diagnostic procedures. Although the procedure is performed under local anesthesia, patients remain conscious throughout, and procedural pain and anxiety are commonly reported. Non-pharmacological interventions to manage these symptoms are increasingly being explored as adjuncts to standard care.

Virtual reality (VR) is an immersive technology that engages the user's visual and auditory senses, potentially distracting patients from procedural discomfort. This randomized controlled trial examined the effect of VR on pain and anxiety in patients undergoing elective coronary angiography.

Patients were randomized into two groups using a sealed envelope method. The VR group watched a pre-selected nature-themed video through a VR headset throughout the procedure. The control group received standard care without any additional intervention. Pain was assessed using the Visual Analog Scale (VAS) and anxiety was measured using the State-Trait Anxiety Inventory (STAI) before and after the procedure.

The study was conducted at a cardiology unit in Istanbul, Turkey, and was approved by the institutional ethics committee (Approval No: 2019-84). Written informed consent was obtained from all participants prior to enrollment.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Virtual Reality Group
Participants watched a nature-themed virtual reality video through a VR headset throughout the coronary angiography procedure in addition to standard care.
Participants in the VR group wore a virtual reality headset and watched a pre-selected nature-themed video throughout the coronary angiography procedure. The VR intervention was applied in addition to standard care and was maintained for the entire duration of the procedure.
No Intervention: Control Group
Participants received standard care without any additional intervention during coronary angiography.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pain Intensity Measured by Visual Analog Scale (VAS)
Time Frame: Measured before and immediately after the coronary angiography procedure
Pain was assessed using the Visual Analog Scale (VAS), a 10-cm horizontal scale where 0 indicates no pain and 10 indicates the worst imaginable pain.
Measured before and immediately after the coronary angiography procedure

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
State-Trait Anxiety Level Measured by State-Trait Anxiety Inventory (STAI-S)
Time Frame: Measured before and immediately after the coronary angiography procedure
Anxiety was assessed using the State-Trait Anxiety Inventory (STAI), which measures state anxiety (STAI-S) and trait anxiety (STAI-T). State anxiety reflects current anxiety levels, while trait anxiety reflects general anxiety disposition. Higher scores indicate greater anxiety.
Measured before and immediately after the coronary angiography procedure
