Aim: The aim of this paper is to use a systematic review and meta-analysis to analyze the effectiveness of aerobic and resistance training on blood Flow mediated dilationMethods: In this study, flow mediated dilation was selected as valid index for vascular endothelial function. Search was done in databases PubMed, science direct, Scopus, Web of science, SID, Magiran and google Scholar with specified keywords among articles that were published in the years 1986 to 2016 both in Persian and English. After initial screening, full text search and critical appraisal, studies which pass the inclusion criteria were analyzed.Results: From a total of 1562 articles that were analyzed, 23 received the study inclusion criteria for the systematic review. 14 study, which included 17 trials with meta-analysis inclusion criteria were analyzed. The results of the meta-analysis of studies showed that exercise can improve Flow mediated dilation in healthy subjects (SMD= 0/84, 95 % CI 0/55–1/13, p=0/001) and patients with coronary artery disease (SMD= 0/49, 95 % CI 0/30–0/68, p=0/001). Although the effect size obtained for different sports are different, but considering the low number of studies, we cannot make an absolute statement about the superiority of one method of training.Conclusion: The exercise can be effective in improving endothelial function, although still high-quality research studies with sufficient sample size is needed.

Background & Objectives: Cardiovascular disease is the main cause of death and disability worldwide and is known as one of the major threats to human health. Therefore, this study was aimed to investigate the changes in mortality from cardiovascular disease in Iran. Materials and Methods: This cross-sectional study was done using analysis of data published in the mortality profile in Iran (29 Provinces) over the years 2006 to 2010. The trend of mortality due to cardiovascular disease in both sexes was drawn during the period of the study according to age groups in the 2010 and their frequency distributions. The WinPepi software was used for data analyses. Results: Evaluation of the mortality profile in Iran (29 Provinces) over the Years 2006 to 2010 is shown that, during these years, the number of deaths from all causes in the country was 1,172,278, which 46.04 percent of them (539,679 cases) were due to cardiovascular disease. Also, according to the data on the mortality from cardiovascular disease, a decreasing trend was observed in the country during 2006 to 2008, while an increasing trend was observed the years 2009 to 2010. Highest number of deaths due to cardiovascular disease was reported in 2006, 115,985 cases, while least number was reported in 2008, 104,126 cases. Conclusion: Because the risk of death from cardiovascular disease increases with ageing, medical interventions for the prevention of cardiovascular disease risk factors in childhood and adolescence and, also, in-time treatment of the patients can be used for preventing from mortality resulted from these disease.

Background: Fibrinogen (Fib) as a separate factor and influencing the risk of Cardiovascular is associated with the development of coronary heart disease. On the other hand, intense exercise increases the rate of early heart attacks. Due to the increased risk of abnormal clotting of blood vessels by intense exercise and the role of fibrinogen in cardiovascular diseases, strategies such as cocoa consumption has become more widespread. Materials and Methods: in a one-group double-blind experimental study, 11 elite male karateka (mean age: 21±2 years; height: 176.96± 3.41 cm) were participated randomly in two consecutive weeks (first week: placebo: six subjects and cocoa: five subjects, second week: placebo: five subjects and cocoa: six subjects) of exhaustive exercise (Bruce). Each athlete, after the first stage of blood sampling, the bottles contained placebo and cocoa into the mg.kg-1 5 will consume and two hours later did the Bruce test. Therefore, each athlete did the test tow order (1- after placebo consumption, 2- after cocoa consumption). Immediately before the test, immediately after and one hour after the test, a blood sample in the second, third and fourth were taken. Differences were examined using a two-factor analysis of variance (ANOVA) with repeated measures as appropriate. Results: Significant differences in fibrinogen levels during different stages of the cocoa consumption were not observed. These results indicate no effect of cocoa consumption on indicators of fibrinogen (P

Background and purpose : Rheumatoid arthritis (RA) is an inflammatory disorder which leads to an increase in casualties caused by cardiovascular disease (CVD). Adipocytokines and hs-CRP play a main role in pathophysiology of RA and CVD. Soy foods and phytoestrogens have anti-inflammatory properties. So, this study was designed to determine the effects of soy milk consumption comparing with cow’s milk consumption on anthropometric indicators, blood pressure (BP), hs-CRP, adiponectin and leptin among patients suffering from RA.
Material and methods: This randomized, crossover clinical trial was conducted on 30 patients. This study had two intervention periods, each lasted 4-weeks. Subjects were divided in two groups of consuming soy milk (one glass per day) and cow's milk (one glass per day). The wash‐out period was two weeks. Variables were measured before and after of each intervention.
Results: Soy milk consumption resulted a significant reduction in hs-CRP levels (percent change: -13.81±5.39 vs. 9.21±6.33%; P˂0.008). Serum levels of adiponectin decreased in soy milk group (baseline: 38.39±2, end: 30.71±1.9; P˂0.01). However, this reduction was not significant comparing with cow’s milk (p=0.096). We have not seen any significant differences in leptin levels, weight and BP between two interventional periods (p˃0.05).
Conclusion: Soy milk consumption for 4 weeks could decrease serum levels of hs-CRP, and had no significant effects on other variables in patients suffering fromRA.
