Objective: This study aimed to investigate the impact of listening to pleasant natural sounds on anxiety
and physiological parameters in patients undergoing coronary angiography.
Methods: The present pragmatic quasi-randomized controlled clinical trial was conducted on 130 patients
undergone elective angiography. The participants were randomly divided into two groups,
including a pleasant natural sounds group, and a control group (n1/2 65 per group). Spielberger's state/
trait anxiety inventory was used to assess levels of anxiety. The patients' anxiety level and physiological
parameters were measured at baseline, before, during, immediately after, and 20 min after coronary
angiography.
Results: The mean level of anxiety was similar in both arms at baseline (t ¼ 1.317, df ¼ 128, p ¼ 0.190).
The intervention arm displayed significantly lower anxiety levels than the control arm during the
intervention (Wilks' lambda 0.11, Pillai's trace 0.89, P 0.001, F 2.05). The physiological parameters (systolic
and diastolic blood pressure, mean arterial pressure, heart rate, and oxygen saturation) of both
groups showed statistically significant differences (p < 0.05) over time and in group-by time interactions.
Conclusion: As an effective nursing intervention presenting no side-effects, listening to pleasant natural
sounds can be helpful in the management of anxiety
