Abstract

Most studies have shown the positive effects of lavender inhalation in decreasing anxiety in patients with cardiovascular diseases. We aimed to systematically review the role of aromatherapy with lavender in these patients. By PRISMA standards, we explored the studies on the role of aromatherapy with lavender in reducing the anxiety of patients with cardiovascular diseases in English databases through the words and terms “aromatherapy”, “lavender”, “lavandula”, “anxiety”, “cardiovascular diseases”. Out of 16 647 papers, 12 papers up to January 2022 encountered the inclusion criteria for involving in this systematic review. The majority of studies (7 studies, 70%) were used Spielberger Standard Questionnaire as a measurement scale for their studies. Lavender aromatherapy was mostly used for myocardial infarction (3 studies, 30%) and coronary artery bypass graft (CABG) surgery (3 studies, 30%) patients. We concluded that aromatherapy with lavender essential oil significantly ameliorated the anxiety signs in some cardiovascular diseases, e.g., CABG surgery, myocardial infarction, and cardiac ischemia; however, more studies are required in this field to obtain more specific evidence.

Most studies have shown the positive effects of aromatherapy with lavender essential oil on the anxiety of patients with cardiovascular diseases. However, due to the low quality of studies and the low number of studies used, and the disagreement of some studies regarding the positive effect of lavender essential oil on anxiety in cardiovascular patients, it is suggested that more studies be done in this field to obtain more specific evidence.
