Key result
Peer and video education reduce anxiety before coronary angiography with similar efficacy.
Why the study?
Coronary angiography induces anxiety that can cause physiological responses increasing risk of complications, necessitating effective anxiety-reducing interventions.

Peer or video education reduces pre-angiography anxiety versus control; extends scalable non-pharmacologic options without added benefit from combination.
OBJECTIVES: Coronary angiography can be stressful for patients and anxiety-caused physiological responses during the procedure increase the risk of dysrhythmia, coronary artery spasms and rupture. This study therefore aimed to investigate the effects of peer, video and combined peer-and-video training on anxiety among patients undergoing coronary angiography. METHODS: This single-blinded randomised controlled clinical trial was conducted at two large educational hospitals in Iran between April and July 2016. A total of 120 adult patients undergoing coronary angiography were recruited. Using a block randomisation method, participants were assigned to one of four groups, with those in the control group receiving no training and those in the three intervention groups receiving either peer-facilitated training, video-based training or a combination of both. A Persian-language validated version of the State-Trait Anxiety Inventory was used to measure pre- and post-intervention anxiety. RESULTS: <0.01); however, there was no significant difference in anxiety level in terms of the type of intervention used. CONCLUSION: Peer, video and combined peer-and-video education were equally effective in reducing angiography-related patient anxiety. Such techniques are recommended to reduce anxiety amongst patients undergoing coronary angiography in hospitals in Iran.

Habibzadeh et al. (2018) conducted an RCT in Anxiety among patients undergoing coronary angiography (n=120). Peer-facilitated, video-based, or combined peer-and-video education vs. No training was evaluated on Anxiety measured by the State-Trait Anxiety Inventory (p=<0.01). Peer, video, and combined education interventions significantly reduced anxiety in patients undergoing coronary angiography (P<0.01), with no difference between intervention types.
