The effect of audio-visual education prior to coronary angiography on the state anxiety

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.
