Abstract
Abstract Background Aromatherapy consists in the use of volatile aromatic compounds of plant essential oils. Application methods include massage, baths, and mainly inhalation. Lavender essential oil is considered the most effective treatment for emotional disorders, such as stress and anxiety, due to its anxiolytic and sedative agents, which are known to interfere with physiological cardiovascular reactions. Objectives To investigate the effects of aromatherapy using lavender essential oil on hemodynamic responses and emotional aspects of patients with cardiovascular diseases. Methods A [...]
Highlights
Cardiovascular diseases have the highest incidence of morbidity and mortality in the world
Reductions were demonstrated in hemodynamic responses, such as systolic and diastolic blood pressure, mean arterial pressure, and heart rate, as well as a decrease in anxiety, depression, stress, and fatigue compared with the control group
This review demonstrated that the topic of cardiovascular response to aromatherapy has not been fully explored, as there are only a few studies with a design that supports the use of aromatherapy with lavender essential oil as a therapeutic resource in the control of hemodynamic responses and emotional aspects in patients with cardiovascular diseases
Summary
Cardiovascular diseases have the highest incidence of morbidity and mortality in the world. According to the World Health Organization (WHO), they caused approximately 17.9 million deaths in 2016, accounting for 31% of all causes of death worldwide.[1] Stress and anxiety seem to destabilize cardiovascular regulation, adversely affecting the autonomic and neuroendocrine pathways and, cardiovascular parameters and tissue perfusion.[2,3] Recently, Ma et al.,[4] observed that negative emotions can increase systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and cortisol levels, whereas positive emotions can decrease SBP and HR. Lavender essential oil is considered the most effective treatment for emotional disorders, such as stress and anxiety, due to its anxiolytic and sedative agents, which are known to interfere with physiological cardiovascular reactions
