Abstract
BackgroundSleep disorder is a critical problem in cardiac patients. This study aimed to compare the effects of aromatherapy with peppermint and lavender essential oils on the sleep quality of cardiac patients.MethodsA total of 105 patients were randomly allocated to three groups of peppermint essential oil, lavender essential oil, and control. In each experimental group, the patients inhaled three drops of lavender and peppermint essential oils, whereas the control group received aromatic distilled water. Data were collected using the Pittsburgh Sleep Quality Index (PSQI). The participants completed PSQI before and after the intervention.ResultsThere was a significant difference in the mean score of PSQI in each of the experimental groups before and after the intervention; however, the difference was not statistically significant between the experimental groups.ConclusionAromatherapy with lavender and peppermint essential oils can improve the sleep quality of cardiac patients. Therefore, use of this non-pharmacological intervention, as an effective and simple approach, is recommended for cardiac patients.Trial registrationIRCT, IRCT201601244736N10.

Summary
One of the most common problems in cardiac patients is sleep disorder (Karadag et al, 2017; Cho et al, 2017). Sleep disorder is common in CCU patients due to multiple reasons, such as fear of death, pain, unfavorable odor of the CCU setting, nursing interventions, loss of privacy, noise, and poor lighting (Karadag et al, 2017; Hajibagheri et al, 2014). Improvement of the sleep quality of cardiac patients is one of the most important nursing interventions (Oshvandi et al, 2014). Sleep disorder is a critical problem in cardiac patients. This study aimed to compare the effects of aromatherapy with peppermint and lavender essential oils on the sleep quality of cardiac patients.
