Key result
Video education reduces pre-coronary angiography anxiety scores by ~16 points compared to verbal information alone.
Why the study?
The effectiveness of pre-procedural audio-visual video education on psychosocial stress, anxiety, and physiological parameters in patients undergoing coronary angiography needed evaluation.
Does audio-visual (video) education given the day before the procedure reduce pre-procedural state anxiety and physiological stress parameters (heart rate and blood pressure) compared to verbal information alone in patients undergoing first-time diagnostic coronary angiography?
Does audio-visual (video) education given the day before the procedure reduce pre-procedural state anxiety and physiological stress parameters (heart rate and blood pressure) compared to verbal information alone in patients undergoing first-time diagnostic coronary angiography?
Providing audio-visual video education one day prior to first-time diagnostic coronary angiography significantly reduces pre-procedural state anxiety, heart rate, and blood pressure compared to standard verbal information.
Video education may ease pre-procedural anxiety before angiography; hypothesis-generating and requires randomized confirmation before practice change.
Objective: The purpose of this study is to evaluate the effectiveness of the audio-visual (video) education given to patients undergoing coronary angiography (CAG) over psychosocial (stress, anxiety) and physiological parameters. Methods: This study included 120 consecutive patients (60 experiments, 60 controls) who underwent diagnostic CAG for the first time. Depression and anxiety levels were evaluated in all patients at admission. The day before the CAG procedure, the audio-visual (video) education was given to experimental group. The control group was informed only verbally about the procedure. 10-20 minutes prior to coronary angiography in all patients the level of state anxiety was measured, and blood pressure-heart rate were recorded. Data were statistically analyzed with SPSS16 statistical software. Results: The average state anxiety score just before CAG procedure, the values of the pulse, systolic and diastolic blood pressure were significantly lower in the experimental group applied audio-visual education compared to control group given verbal information. Conclusions: Compared to verbal information, the audio-visual(video) education for CAG applied to the patients before the procedure, could have a more positive effect on anxiety levels, blood pressures and heart rates.

Başar et al. (2015) studied Patients undergoing first-time diagnostic coronary angiography for evaluation of chest pain (n=120). Audio-visual (video) education vs. Verbal information only was evaluated on State anxiety score (STAI Form TX-1) measured 10-20 minutes prior to coronary angiography (p=<0.001). Audio-visual (video) education prior to coronary angiography significantly lowered pre-procedural state anxiety scores compared to verbal information alone (32.6 ± 4.1 vs 48.1 ± 3.7, P<0.001).
