Abstract
Introduction: Studies have shown that there is a relationship between metabolic syndrome and coronary heart disease. Hypertension is a common risk factor of both cardiovascular diseases and metabolic syndrome. The aim of this study is to determine the prevalence of metabolic syndrome phenotypes in patients with hypertension in Isfahan and Markazi provinces in center areas of Iran. Materials and Methods: This cross-sectional study was implemented in Isfahan and Markazi provinces in year 2001. Sampling method was random-clustering. 12514 people from both sexes who were above 19 years old were considered which based on ATP III, 1936 person of them had metabolic syndrome. Based on the definition, these people were those who at least had three of the following factors abnormally: HTN, FBS, TG, HDL and WC. Also hypertension was considered for all groups. Data was analyzed using Chi square test and Odds ratio. Results: The prevalence of metabolic syndrome was 0.6% to 7.5% in central areas of Iran. The most prevalent of metabolic syndrome was in hypertensive women with high TG and WC and the least prevalent was in hypertensive men with these two phenotypes: 1-high FBS and WC, and 2-high FBS and low HDL (p<0.05). Overall prevalence of metabolic syndrome in hypertensive people in the most of urban population was more than rural population. Conclusion: Results showed that hypertension is associated with different metabolic syndromes, especially in women with central obesity and dyslipidemia which necessitates more attention in preventing and treatment of the disease in this high risk group.

Abstract
Introduction:Hyperlipidemia is one of the major risk factors of cardiovascular diseases. This study was done to assess lipid profiles according to sex and place of residence in the urban and rural area of Arak for controlling cardiovascular diseases. Materials and Methods:This descriptive study is the first phase of healthy heart program which was done in Arak. Sampling was randomized cluster. A questionnaire was used to collect demographic data and paraclinical test results (total cholesterol, LDL-c, HDL-c ,and Triglyceride). Data was analyzed using T-student, Kolmogorov-Smirnov, Mann-Whitney and Chi-square tests. Results: Of 4303 individuals over 30 years, 51.6% were female. Total cholesterol, LDL-c and HDL-c disturbances were more in female (p<0.05) but there was not a sigmifiant difference between male and female in triglyceride disturbance. The increase in serum lipids was signfiantly different in urban and rural areas, in which total cholesterol and LDL-c disturbances were more in rural and triglyceride disturbance was more in urban areas (p<0.0001). Conclusion: High prevalence of dyslipidemia in the studied region can be related to unhealthy life style, nutrition and inadequate physical activity, so dyslipidemia and cadiovascular diseases could be decreased by changing lifestyle.

Abstract
Background: Research has shown that healthy individuals with no known cardiovascular risk factors who experience a stressful life are likely to develop cardiovascular diseases. Therefore, stress can be one of the most important risk factors involved in cardiovascular diseases. This study evaluated the possible effects of chronic stress induced by obligatory swimming and noise on coronary arteries histological changes. Materials and Methods: In this experimental trial, male Wistar rats were exposed to two different types of chronic stresses, including physical obligatory swim stress and psychological noise stress. After the last stress session, the rats were examined in terms of the ratio of the vessel lumen diameter to outer diameter, ratio of media diameter to outer diameter, ratio of adventitia diameter to outer diameter, and ratio of wall thickness to outer diameter of vessels. Results: Obligatory swimming stress and noise stress each significantly increased the ratio of media diameter to the outer diameter of vessels (P<0.001) and decreased the ratio of vessels lumen diameter to the outer diameter (P<0.05). Swimming stress and noise stress induced increases in the ratio of wall thickness to the outer diameter of vessels (P<0.01, P<0.05, respectively). In addition, swimming stress significantly increased the ratio of adventitia diameter to the outer diameter of vessels (P<0.05).
Conclusion: These findings suggest that chronic stress can induce coronary vessel remodelling which results in atherosclerosis and cardiovascular diseases

Abstract
Background: Probiotics are live microorganisms that have positive effects on the host when consumed in sufficient amounts. According to several studies, probiotics have beneficial effects on prevention and treatment of many diseases. The aim of this study was to review animal and human studies on the role of probiotics in reducing serum cholesterol, their mechanisms of action, and a brief explanation of functional probiotic foods. Materials and Methods: This review article focused on all papers indexed in scientific databases from 2000 to 2012 using the related keywords, including cardiovascular diseases, probiotics, and serum cholesterol. Results: Probiotics are used both in dairy and non-dairy products. Nowadays, the role of many probiotic strains in health is confirmed. From the studies done in this field, it can be inferred that probiotics through several mechanisms, such as binding cholesterol to cell walls of probiotics in intestine, conversion of cholesterol into coprostanol, production of short chain fatty acids, and deconjugation of bile acids, reduce serum cholesterol. Conclusion: Certain strains of probiotics have demonstrated cholesterol-lowering properties and others are under study. Further studies are needed to identify other mechanisms involved in lowering serum cholesterol and determine their safety

Abstract
Background and Aim: Diabetes mellitus is one of the leading causes of death, and its prevalence is increasing annually because of the change in lifestyle. Increased blood glucose level and dyslipidemia are the major symptoms of this metabolic disease. Currently, the main and effective treatment for diabetes is the use of medication such as insulin. Its control by using herbal products has received a lot of attention in the world. The aim of this study is to evaluate the effects of bioflora (a probiotic supplement) and aqueous extract of cinnamon in improvement of blood glucose level, dyslipidemia, and reduction of cardiovascular diseases in diabetic rats.
Methods & Materials: Thirty-five male Wistar rats were prepared and randomly divided into five groups of negative control, positive control, probiotic (treated with bioflora 3.2×108 CFUs/day for 30 days), cinnamon (treated with 200 mg/kg of cinnamon aqueous extract for 30 days), and probiotic + cinnamon. Diabetes was induced by intra-peritoneally injection of streptozotocin. The rats’ weight, blood glucose level, lipid profile, high sensitivity C-Reactive Protein (hs-CRP) and Atherogenic Index (AI) were measured at the end of experiment to predict the risk of cardiovascular diseases.
Ethical Considerations: This study ethically approved in Research Centre of Islamic Azad University of Arak (Code: IR.IAU.ARAKREC1397.005). All interventions performed in accordance with the Guide for Care and Use of Laboratory Animals prepared by the Institute of Laboratory Animal Resources.
Results: Induction of diabetes caused severe weight lost in rats, but the weight loss was lower in groups treated with probiotic. The blood glucose level in probiotic + cinnamon group was significantly reduced. Bioflora reduced triglyceride, cholesterol, and Low-Density Lipoprotein Cholesterol (LDL-C) levels, while cinnamon extract significantly reduced triglyceride and LDL-C levels compared to the positive control group. AI and hs-CRP values were reduced in the probiotic group compared to control groups. There was no synergistic effect by combined use of bioflora and cinnamon extract.
Conclusion: Bioflora effectively prevented dyslipidemia by improving intestinal microbiota, lowering blood glucose level, and improving lipid profile and, therefore, reduced the risk of cardiovascular diseases.

Abstract
Introduction: Hyperlipidemia, a chronic metabolic disorder marked by elevated blood lipid levels, significantly increases the risk of cardiovascular disease in individuals with diabetes, hypertension, and obesity. While pharmacological interventions exist, factors such as medication side effects, cost considerations, and a growing interest in complementary and alternative medicine have stimulated research into the therapeutic potential of medicinal plants in managing hyperlipidemia. This study aims to assess the efficacy and safety of these botanical agents in reducing blood lipid levels.
Methods: A comprehensive literature search was conducted across reputable databases, including PubMed, ScienceDirect, Google Scholar, and other relevant online platforms. Keywords such as "hyperlipidemia," "herbal medicine," "traditional medicine," "herbal extract," and "herbal therapy" were employed to identify studies published up to 2024. Inclusion criteria were established to select studies that reported the impact of medicinal plants on lipid profile modifications.
Results: Based on the results, the study revealed that various medicinal plants, including Thymus vulgaris, Apium graveolens, Cichorium intybus, Fumaria officinalis, Heracleum rawianum, Anthemis altissima, Gundelia tourneforttii, Cynodon dactylon, Anthriscus sylvestrianum, Solanum nigrum, Arum elongatum, Glycyrrhiza glabra, Berberis vulgaris, Rheum ribes, and Mentha spicata, are commonly used in traditional medicine to address hyperlipidemia.
Conclusions: The use of indigenous Iranian medicinal plants for managing hyperlipidemia is deeply rooted in the country’s ancient history and has been increasingly validated by contemporary scientific research. These natural compounds can help lower blood lipid levels by inhibiting fat absorption and boosting lipid metabolism. The growing interest in traditional medicine and medicinal plants can be attributed to their inherent advantages, such as a lower incidence of side effects compared to synthetic drugs. Ongoing scientific research in this field offers promising avenues for developing innovative and effective herbal-based therapies
