Impact of inhalation aromatherapy with Damask Rose (Rosa damascena) on stress, anxiety and hemodynamic parameters of patients undergoing coronary angiography: a single blind randomized clinical trial.

OBJECTIVES: Coronary arteries angiography is used commonly for diagnosing cardiovascular diseases. In spite of the low risk of coronary artery angiography method, it could lead to stress, anxiety and consequently hemodynamic changes in patients. This study aimed to assess the effects of inhalation aromatherapy with Rosa damascena on stress, anxiety, and hemodynamic parameters of patients undergoing coronary angiography. METHODS: A single-blind randomized clinical trial was conducted on 98 patients in Besat Educational Hospital, Hamadan, Iran. Before coronary angiography, patients at aromatherapy group inhaled five drops of 40% Rosa damascena for 20 min and in the control group, patients inhaled distilled water. Stress, anxiety, and hemodynamic parameters were measured before and after the intervention using DASS-21 questionnaire and checklist. RESULTS: Data were analysed by SPSS 16 software using descriptive and inferential statistics such as paired t-test and non-parametric tests. There were significant differences in terms of stress and anxiety severity in patients at aromatherapy group (p=0.005) and control group (p=0.001). There were significant differences in terms of hemodynamic parameters such as heart rate (p=0.001), mean arterial pressure (p=0.001), systolic (p=0.003) and diastolic blood pressure (p=0.001) and SpO2 (p=0.02). CONCLUSIONS: Inhalation aromatherapy with Rosa damascena can significantly decrease stress and anxiety severity and improve hemodynamic parameters of patients undergoing coronary angiography. REGISTRY NUMBER: This study has registered with the number IRCT201702019759N8 at Iranian Registry Clinical Trial.

Prevalence and Incidence of Metabolic Syndrome in Iran: A Systematic Review and Meta-Analysis.

Metabolic syndrome (MetS) is a predictor of several diseases such as cardiovascular diseases, diabetes, dyslipidemia, stroke, osteoarthritis, certain cancers, and death leading to public health concern in most societies. We aimed to estimate the pooled prevalence and incidence of MetS in Iranian population through a meta-analysis study. We included cross-sectional and cohort studies to estimate the overall prevalence and incidence rates of MetS in Iran National databases including MagIran, Science Information Database, IranMedex, and international databases including Medline, Web of Sciences, and Scopus were searched up to October 2017. Finally, 125 studies were included. The total sample size was 472,401 with a mean age of 38 ± 7.8 years. The overall pooled prevalence and incidence rate among the general population of Iran was 0.26 (95% CI: 0.26, 0.29) and 97.96 (95% CI: 75.98, 131.48), respectively. The pooled prevalence of MetS was higher in females and in urban areas. The highest and lowest prevalence of MetS was obtained by the Iranian definition criteria (0.43) and the NHANES III (0.12). The highest and lowest incidence rates of MetS were obtained by IDF (144.07 per 1000) and the JIS (89.73 per 1000). The prevalence of MetS was higher in women and those living in urban areas. Furthermore, the prevalence of MetS increased with increasing age in both genders.
