Introduction: Anxiety is among the most common problems experienced by coronary angiography (CA) candidates. Different modalities are used to manage anxiety. This study sought to examine the effects of a pranayama exercise on CA candidates’ anxiety.
Methods: This double-blind randomized controlled trial was undertaken in 2015 on 80 eligible patients. The patients were randomly allocated to a control and an experimental group. Before undergoing angiography, patients in the experimental group performed sukha pranayama exercises. They were trained to breathe slowly and rhythmically at a rate of ten breathing per minute for five consecutive minutes. Patients in the control group only received routine pre-angiography care. Data collection tools were a demographic questionnaire and the Spielberger State Anxiety Inventory. The level of patients’ anxiety in both groups was measured before, half an hour after, and one hour after the intervention. The data were analyzed through doing the independent-sample t and the chi-square tests.
Before the intervention, the mean of anxiety score in the experimental group was 53.37, which significantly decreased to 40.75 after the intervention (P = 0.0001). In the control group, the mean of anxiety score decreased from 54.27 to 51.4. This decrease was not statistically significant. Moreover, between-group comparisons revealed significant differences between the groups regarding between-measurement mean differences of anxiety score (P < 0.01).
Sukha pranayama is effective in alleviating CA candidates’ anxiety.
