Abstract

Objective

In cardiovascular disease, a patient's anxiety and depression can increase cardiac rehabilitation duration and recovery. Lavender aromatherapy as a non-pharmacological intervention effective in other contexts may be an efficient intervention to alleviating anxiety and depression in patients with Acute Coronary Syndrome (ACS).

Methods

In this study, 110 ACS patients were randomly assigned to two intervention and control groups. Inhalation of the lavender fragrance was prescribed for the intervention group and the drop of aromatic almond for the control group for 3 days.

Results

The first-day anxiety and depression were significantly different in the two groups at 1 h and 9 h after the intervention. The ’morning's difference before the intervention was not significant, but it was substantial 1 h after the intervention. On the third morning of the intervention, this difference was confirmed.

Conclusions

This study confirmed the effectiveness of lavender aromatherapy in reducing anxiety and depression in ACS patients. This ‘study's results enable intensive care nurses to use aromatherapy with lavender oil as a non-pharmacological and cost-effective intervention to reduce their psychological tensions and increase patient satisfaction during hospitalization in the cardiac care units (CCU).
