Abstract

Abstract: Stress and hemodynamic changes are among the most significant symptoms and signs that could be observed in patients with acute coronary syndrome (ACS) upon admission to the emergency department. The present study was conducted to determine the effect of the fragrance of lemon balm ( Melissa Officinalis ) essential oil on stress level and hemodynamic parameters in patients with ACS in the emergency department. Methods: In this double-blind clinical trial, 72 patients were allocated to two groups of Melissa and placebo based on stratified block random sampling. The Melissa group inhaled two drops of Melissa essential oil, whereas the placebo group inhaled two drops of sunflower oil in two aromatherapy phases for 10 min with 90-min intervals. Stress level was measured using the depression, anxiety and stress scale (DASS-21), and hemodynamic parameters were measured and recorded in six time points by a cardiac monitoring system. Data analysis was carried out using descriptive statistics and ANOVA statistical tests, Chi-square test, independent t -test, and post-hoc Tukey's test. Results: Interaction between the time and group indicated the significant decrease in the mean score of stress and heart rate in the time points 2 and 5 (5 min after every occasion of aromatherapy) (p < 0.001) and also the remarkable decrease in the mean arterial pressure (MAP) in the time point 2 in the Melissa group in comparison with the placebo group (p < 0.001). There were no significant differences between the mean changes in stress, heart rate and MAP in the two group (P > 0.05). Conclusion: Aromatherapy via the inhalation of Melissa essential oil with temporary impacts on certain time points could relieve stress and regulate hemodynamic changes in patients with ACS in emergent and acute conditions. Highlights: IInhalation of Melissa oil has a significant effect on decreased acute stress in patients with ACS in the emergency department. Aromatherapy with Melissa oil has a significant effect on decreased threat perception and pain intensity in patients with ACS. Aromatherapy with Melissa essential oil might temporarily contribute to stress relief and the regulation of MAP and heart rate.
