The Effect of a Multi-Modal Preparation Package on Anxiety in Patients Undergoing Coronary Angiography

Background: There are differences in studies on the effect of non-pharmacological methods of anxiety reduction in patients undergoing coronary angiography.

Objectives: The present study aimed to evaluate the effect of implementing a multi-modal preparation package on anxiety in patients undergoing coronary angiography.

Patients and Methods: This single blind randomized clinical trial was conducted on 100 patients undergoing coronary angiography. The patients were equally assigned to an intervention and a control group. The preparation package was implemented about two hours prior to angiography. Spielberger’s anxiety inventory was used for measuring anxiety. The patients’ anxiety level was measured the day before, immediately before, and after implementing the preparation package and 30 minutes before angiography. Then, the data were entered into the SPSS statistical software, version 11.5 (SPSS Inc., Chicago, IL, The USA) and analyzed using T-test and repeated measures ANOVA. Chi-square test was also used to compare the two groups’ demographic characteristics. P values < 0.05 were considered as statistically significant.

Results: The results revealed no significant difference between the control group (34.36 ± 5.56) and the intervention group (34.64 ± 4.71) regarding baseline anxiety mean scores (P = 0.787). This score increased in the control group (38.14 ± 7.36) as well as in the intervention group (38.94 ± 5.36) 2 hours before angiography (P = 0.536). However, the mean anxiety score decreased to 34.16 ± 2.75 in the intervention group and to 40.38 ± 8.16 in the control group immediately after applying the preparation package (P = 0.001).

Conclusions: The preparation package reduced anxiety before angiography. Considering the beneficial effects of this preparation package on reducing anxiety, this method is recommended for preparation of patients for coronary angiography.
