Hilt's law (dependence of the coalification degree on depth) is a substantial and long-acknowledged rule. Its validity in the Czech part of the Upper Silesian Coal Basin (Carboniferous, Mississippian to Pennsylvanian - Lower Namurian to Westphalian A) is the subject of this study. It is based on over 29,000 analyses of the volatile matter moisture- and ash-free (V daf ) from surface and underground boreholes drilled in 1946-1989. Vitrinite reflectance (R max ) cannot be used as a measure of coalification in the Upper Silesian Coal Basin: the number of reflectance measurements is small and their distribution over the basin area is very uneven. Statistical data on V daf for the individual stratal units were processed. Modelling of the trends in the volatile matter moisture- and ash-free (V daf ) depending on ''stratigraphic depth'' proved the general applicability of Hilt's law. The distribution of this parameter in selected boreholes and segments of the basin was also studied, and coalification gradients were calculated. Coalification in specific examples (boreholes) is, however, highly variable and shows numerous deviations from Hilt's law even within individual boreholes, which is documented on a real example. The causes of some of the deviations are relatively well known (e.g., effect of elevated pressure in tectonically deformed areas, effect of effusive rocks or paleoweathering zones) while others can be presumed (heat flows due to Variscan and Carpathian orogenies affected by the lithology of the Carboniferous massif). The contribution of these effects in specific examples can be determined with great difficulty only. (author)

1977-12-01

Statistical analysis proved that contamination with dirt of run of mine coal from seams in the series 200 to 600 of the Upper Silesian Coalfield depends on the average ash content of a given raw coal. A regression equation is deduced for coarse and fine sizes of each coal. These equations can be used to predict the degree of contamination of run of mine coal to an accuracy sufficient for coal preparation purposes.

Full Text Available The Upper Silesian urban-industrial agglomeration is one of the most industrialized areas in Europe. The intense industrialization should be attributed mostly to the presence of coal and other minerals deposits and its extraction. Mining areas of hard coal mines comprise approximately 25% of the total catchment area of watercourses in the area of Upper Silesian Coal Basin, including the river basin of the Upper Oder River and the Little Vistula River. The mining, its scope and depth, duration of mining works, extraction systems being used and the total volume of the drainage fundamentally affect the conditions of groundwater and surface water in the studied area. In this paper, an overall characteristics of the coal mining industry in the area of USCB was made, including the issues of its influence on water environment in the light of the requirements of the Water Framework Directive (WFD and its guidelines transposed into Polish law. An analysis of the collected data, obtained from collieries, relating to the quantity and quality of water flowing into the workings and discharged to surface watercourses, was performed. An approach to the requirements for wastewater discharge into the environment by these enterprises was presented regarding the physicochemical parameters, possible harmful substances and radionuclides measured in mine waters. The main goal of the paper is to recognize the condition of surface water bodies in the area of Upper Silesian Coal Basin and to make the assessment of the biological condition using Ecological Risk Assessment and bioindication methods.

Full Text Available BACKGROUND: Regular physical activity is an important factor in human health status. The fact, that the physical activity will be regular, is influenced by many internal and external individual factors. Education is considered to be an important factor that influences physical activity. There has not been fully clarified the relationship between physical activity and education in pursuit of regional indicators yet. AIM: The aim of this study was to analyze the physical activity of adult inhabitants of the Moravian-Silesian region with regard to the number of years spent in formal education. METHODS: The research sample consisted of 759 residents of MoravianSilesian region (419 women and 340 men aged 25-58. The IPAQ questionnaire was used to obtain the data, which was distributed by trained university students in the spring and autumn periods of 2005-2009. Kruskal Wallis ANOVA test was used for the statistical evaluation of the data. The effect size was calculated to clarify the internal differences in results. RESULTS: Significant differences in the structure of physical activity were found only in men in the job related physical activity (H = 6.277; p = 0.05; η2 = 0.019 and in vigorous physical activity (H = 6.230; p = 0.05; η2 = 0.018. Physically most active are men with lowest level of education. No significant difference was found in the monitored parameters for women. Job related physical activity means the highest part of the total physical activity in respondents with lowest education. CONCLUSION: The results of the survey point to the fact, that different level of education is not an important factor associated with physical activity in Moravian-Silesian region. To promote physical activity we would recommend focusing on physical activity in leisure time, during transport and on vigorous physical activity in all groups of respondents based on educational level.

Watermills – a Forgotten River Valley Heritage – selected examples from the Silesian voivodeship, Poland

Full Text Available This study is an attempt to describe the current condition of the watermills situated in the river valleys of the Silesian voivodeship. Changes in the number and distribution of mills from the late 18th century until the 20th century have been presented (as exemplified by the Liswarta River basin in the northern part of the voivodeship. Watermills have been discussed both as industrial monuments that document the history of the milling industry and as tourist attractions. Currently, working mills that serve the local population in rural areas are a rarity, and working watermills are unique sites that should be protected as industrial monuments that constitute an important part of our cultural heritage. They are among those industrial monuments that are particularly vulnerable to destruction. Such mills increasingly attract the interest of industrial tourism promoters. Activities aimed at promoting watermills as cultural heritage sites and leading to their protection and preservation as part of the river valley landscape have also been discussed. In the Silesian voivodeship, there are many watermills that deserve attention; some of these are listed in the register of monuments maintained by the National Heritage Board of Poland. Unfortunately, most disused mills are falling into disrepair and are slowly disappearing; only a few have been preserved in good condition. Many of these have long histories and they are also situated in areas attractive for tourists. There is no doubt that watermills should be preserved. Their inclusion in open-air museums is not the only solution – any form of protection in situ by putting them to different uses is also valuable. Changing the function of a mill to serve as a hotel, restaurant, cultural centre, etc. makes it possible to maintain these sites as parts of river valley landscapes.

2009-09-15

Exploitation of coal seams in the Upper Silesian Coal Basin is conducted in complex and difficult conditions. These difficulties are connected with the occurrence of many natural mining hazards and limitations resulting from the existing in this area surface infrastructure. One of the most important problems of Polish mining is the rock burst hazard and reliable evaluation of its condition. During long-years' mining practice in Poland a comprehensive system of evaluation and control of this hazard was developed. In the paper the main aspects of rock burst hazard state evaluation will be presented, comprising: 1) rock mass inclination for rock bursts, i.e., rock strength properties investigation, comprehensive parametric evaluation of rock mass inclination for rock bursts, prognosis of seismic events induced by mining operations, methods of computer-aided modelling of stress and rock mass deformation parameters distribution, strategic rock mass classification under rock burst degrees; 2) immediate seismic and rock burst hazard state evaluation, i.e., low diameter test drilling method, seismologic and seismoacoustic method, comprehensive method of rock burst hazard state evaluation, non-standard methods of evaluation; 3) legal aspects of rock burst hazard state evaluation. Selected elements of the hazard state evaluation system are illustrated with specific practical examples of their application. 11 refs., 14 figs.

Energy Technology Data Exchange (ETDEWEB)

Renata Patynska; Jozef Kabiesz [Central Mining Institute, Katowice (Poland)

2009-09-15

Presently the seismic and rock burst hazard appears still to be important in most of hard coal mines in Poland. Recently, there was a significant increase of seismic activity of the Silesian rock massive, when compared with the previous years. In the period 1999-2008 the hard coal mines experienced 34 rock bursts. The causes of rockburst occurrence are presented based on the analysis of the rockbursts occurring in the Polish hard coal mines. The scale of the rockburst hazard has been characterized with respect to the mining and geological conditions of the existing exploitation. Of the factors influencing the state of rockburst hazard, the most essential one is considered the depth interval ranging from 600 m to 900 m. The basic factors that promote the rockburst occurrence are as follows: seismogenic strata, edges and remnants, goaf, faults, pillars and excessive paneling. 5 refs., 3 figs., 2 tabs.

Having the Mining Industry Restructuring Public Corporation located in the city of Katowice, Poland as the counterpart, a feasibility study has been executed on a project to utilize coal bed gas for power generation. Selected for the study are the 'Budryk coal mine' owned by KWK 'Budryk' Coal Company and the 'Pniowek coal mine' owned by Jastrzebie Coal Company. Since the Pniowek coal mine can utilize the whole quantity of recovered methane by 2001, the Budryk coal mine was selected as the object of the project. As a result of the trial calculation on the economy when the new gas power plant is installed in the Budryk coal mine, the energy substitution effect was found to equal to a power amount at transmission terminal of 6 MWh/year. Furthermore, when proliferation effect is taken into consideration, an enormous effect can be expected if new coal mines are developed and the existing cola mines will go further deeper, because the Silesian coal mine presently has the coal resource quantity of 57 billion tons and the annual gas discharge quantity of 750 million m{sup 3}. Therefore, if the technologies to recover, manage and utilize the gas are established at the Budryk coal mine, a large effect leading to an aspiration would be expected under the current situation of the structural reorganization under which the Polish coal companies are placed.

Full Text Available Underground coal mining is associated with large quantities of gangue. In the past, the majority of gangue was not utilized but was placed in the vicinity of the coalmines forming cone-shaped dumps. Some of them contained even millions of tons of rock. Nowadays, environmental precautions extort larger utilization of any kind of waste materials, for example in road construction, civil engineering or as stowing in underground abandoned workings. Examination of the composition of waste dumps, including radioactivity, is thus an important issue. The paper presents results of a radiological survey carried out in several dumps located in the Upper Silesian Coal Basin in the south of Poland. Measurements of samples were carried out with the use of a gamma-ray spectrometer. Activity concentration results for the uranium and thorium decay chains are discussed.

In China, efforts are underway to respond to rapidly increasing rates of heart disease and stroke. Yet the epidemiology of cardiovascular disease in China may be different from that of other populations. Thus, there is a critical need for population-based studies that provide insight into the risk factors, incidence and outcomes of cardiovascular disease in China. The Qingdao Port Cardiovascular Health Study is designed to investigate the burden of cardiovascular disease and the sociodemographic, biological, environmental and clinical risk factors associated with disease onset and outcomes. For this study, from 2000 through 2013, 32,404 employees aged 18 years or older were recruited from the Qingdao Port Group in China, contributing 221,923 annual health assessments. The mean age at recruitment was 43.4 (SD=12.9); 79% were male. In this ongoing study, annual health assessments, governed by extensive quality control mechanisms, include a questionnaire (capturing demographic and employment information, medical history, medication use, health behaviours and health outcomes), physical examination, ECG, and blood and urine analysis. Additional non-annual assessments include an X-ray, echocardiogram and carotid ultrasound; bio-samples will be collected for future genetic and proteomic analyses. Cardiovascular outcomes are accessed via self-report and are actively being verified with medical insurance claims; efforts are underway to adjudicate outcomes with hospital medical records. Early findings reveal a significant increase in cardiovascular risk factors from 2000 to 2010 (hypertension: 26.4-39.4%; diabetes: 3.3-8.9%; hyperlipidaemia: 5.0-33.6%; body mass index >28 m/kg(2): 14.1-18.6%). We aim to generate novel insights about the epidemiology and outcomes of cardiovascular disease in China, with specific emphasis on the potentially unique risk factor profiles of this Chinese population.

Full Text Available The main goal of the paper is to focus on relationship between business cycle under regional entrepreneurial culture. Many of the trends found were less than positive, although there were some new positive trends that could be identified as a source of sustainability in the area of the connection between the sector of small and medium sized enterprises and the local entrepreneurship environment as well as a source of entrepreneurial culture. Moreover, the frequency of co-operational activities with local government was investigated. Questionnaire-based research was undertaken within 194 organizations of various legal forms operating in the area of the Moravian-Silesian Region. The main factors, which had an influence on their current business stage (49.5% in the growth stage, 9.8% in stagnation, 31.96% in decline and the other 0.52% in crisis, were the locality in the region, the quality of the labour force, cooperation with local public bodies and the business relationships between suppliers. Finally, we have defined the current stage of the entrepreneurial culture as the “Sandbox”.

Genetic aspects of barite mineralization related to rocks of the teschenite association in the Silesian Unit, Outer Western Carpathians, Czech Republic

Directory of Open Access Journals (Sweden)

Jirásek Jakub

2017-04-01

Full Text Available Barite is a relatively uncommon phase in vein and amygdule mineralizations hosted by igneous rocks of the teschenite association in the Silesian Unit (Western Carpathians. In macroscopically observable sizes, it has been reported from 10 sites situated only in the Czech part of the Silesian Unit. Microscopic barite produced by the hydrothermal alteration of rock matrix and also by the supergene processes is more abundant. We examined four samples of barite by mineralogical and geochemical methods. Electron microprobe analyses proved pure barites with up to 0.038 apfu Sr and without remarkable internal zonation. Fluid inclusion and sulphur isotope data suggests that multiple sources of fluid components have been involved during barite crystallization. Barite contains primary and secondary aqueous all-liquid (L or less frequent two-phase (L+V aqueous fluid inclusions with variable salinity (0.4-2.9 wt. % NaCl eq. and homogenization temperatures between 77 and 152 °C. The higher-salinity fluid endmember was probably Cretaceous seawater and the lower-salinity one was probably diagenetic water derived from surrounding flysch sediments during compaction and thermal alteration of clay minerals. The δ34S values of barite samples range between -1.0 ‰ and +16.4 ‰ CDT suggesting participation of two sources of sulphate, one with a near-zero δ34S values probably derived from wall rocks and another with high δ34S values being most probably sulphate from the Cretaceous seawater. All results underline the role of externally derived fluids during post-magmatic alteration of bodies of rock of the teschenite association.

Full Text Available Shopping centers in the Silesian Voivodeship have a significant impact on smaller settlement units located in outer areas of agglomerations. It consists mainly in changes related to social, economic, as well as functional and spatial spheres. Studies shows that shopping centers take over more and more functions of higher order (services, public culture, administration and restrict the economic activity in rural areas outer areas of agglomerations. At the stage of the irrepressible process of suburbanisation of rural areas surrounding large urban agglomerations and structural changes in towns, it is difficult to conclusively assess the consequences of the operation of shopping centers in outer metropolitan areas. The impact of shopping centers on small towns and rural areas is a very dynamic process and requires systematic research.

Full Text Available Despite mandatory vaccinations in Poland, the final decision on vaccination in children is taken by their parents or legal guardians. Understanding parents’ attitudes and opinions regarding vaccinations is essential for planning and undertaking extensive and properly targeted educational actions aimed at preventing their hesitancy. In 2016, a cross-sectional study was conducted in the Silesian Voivodeship (Poland in 11 randomly selected educational institutions. The authors’ self-administered questionnaire contained 24 mixed-type questions. It was distributed among 3000 parents or legal guardians of children aged 6–13 years; prior consent of the relevant bioethics committee had been obtained. The response rate was 41.3% (N = 1239. Data were analysed using descriptive and analytical statistics, and focused on parental opinions regarding the safety of vaccines. Results of simple and multivariable analyses showed that perceived risk of adverse vaccine reaction (AVR, contraindications and perception of the qualification procedure for vaccination as substandard were significant factors associated with the rating of children’s vaccination as unsafe (p < 0.001. Respondents with a lower level of education, compared with those with higher, more often declared vaccinations to be safe (p = 0.03; however, results of multivariable analysis did not confirm that effect. AVR occurrence, finding of contraindication to vaccinations and perception of qualification procedure for vaccination were found to be the most important factors responsible for influencing general public opinions in the field of vaccination safety.

Full Text Available The purpose of this article is to try to classify labour markets of the Silesian Province on the municipality level. The proposed solution of grouping labour markets is based on three criteria: the size of the labour market measured by a number of jobs, the weight of the labour market expressed with a proportion of the number of jobs to the size of the population and that scale of the impact that is a proportion of the commuters to the ones leaving for work. As a result of the assumed criteria the municipalities have been grouped according to their meaning on the labour market, at the same time identifying weaker and stronger labour markets. The first stage of the research was to divide the municipal labour markets according to the number of the employed. As a result territorial units were grouped into 4 classes (small, medium, big and huge including in total 9 subclasses. Then the municipal labour markets were sorted according to their weight and the scale of their impact, verifying their position in this way. The research pointed out that a lot of labour markets in the Katowice conurbation showed lower levels than the assumptions. Consequently, it suggests polarization of the labour market of this urban unit that is mainly focused on Katowice and Gliwice. Higher parameters than the assumed ones were reached by several municipalities that are small or medium labour markets. In many cases these are municipalities where there are huge businesses connected with coal mining. A beneficial situation was noted in the southern part of the province that has a relatively steady situation on the labour market. The presented classification of labour markets can support the management process of local and regional development.

Limited data exist on the epidemiology of cardiovascular risk factors in Saudi Arabia, particularly in relation to the differences between Saudi nationals and expatriates in Saudi Arabia. The aim of this analysis was to describe the current prevalence of cardiovascular risk factors among patients attending general practice clinics across Saudi Arabia. In this cross-sectional epidemiological analysis of the Africa Middle East Cardiovascular Epidemiological (ACE) study, the prevalence of cardiovascular risk factors (hypertension, diabetes, dyslipidemia, obesity, smoking, abdominal obesity) was evaluated in adults attending primary care clinics in Saudi Arabia. Group comparisons were made between patients of Saudi ethnicity (SA nationals) and patients who were not of Saudi ethnicity (expatriates). A total of 550 participants were enrolled from different clinics across Saudi Arabia [aged (mean ± standard deviation) 43 ± 11 years; 71% male]. Nearly half of the study cohort (49.8%) had more than three cardiovascular risk factors. Dyslipidemia was the most prevalent risk factor (68.6%). The prevalence of hypertension (47.5%) and dyslipidemia (75.5%) was higher among expatriates when compared with SA nationals (31.4% vs. 55.1%, p  = 0.0003 vs. p  Saudi Arabia. Improving primary care services to focus on risk factor control may ultimately decrease the incidence of coronary artery disease and improve overall quality of life. The ACE trial is registered under NCT01243138.

An "unhealthy" diet is considered as a main cause of increased atherosclerotic cardiovascular disease in the industrialized countries. There is a substantial interest in the potential cardiovascular protective effects of "nutraceuticals," that is food-derived substances that exert beneficial health effects. The correct understanding of cardiovascular effects of these compounds will have important implications for cardiovascular prevention strategies. Endothelial dysfunction is thought to play an important role in development and progression of atherosclerosis, and the characterization of the endothelial effects of several nutraceuticals may provide important insights into their potential role in cardiovascular prevention. At the same time, the analysis of the endothelial effects of nutraceuticals may also provide valuable insights into mechanisms of why certain nutraceuticals may not be effective in cardiovascular prevention, and it may aid in the identification of food-derived substances that may have detrimental cardiovascular effects. These findings further support the notion that nutraceuticals do need support from large clinical outcome trials with respect to their efficacy and safety profile for cardiovascular prevention, before their widespread use can be recommended. In fact, the term nutraceutical was coined to encourage an extensive and profound research activity in this field, and numerous large-scale clinical outcome trials to examine the effects of nutraceuticals on cardiovascular events have now been performed or are still ongoing. Whereas it is possible that single nutraceuticals may be effective in cardiovascular prevention, this field of research provides also valuable insights into which food components may be particularly important for cardiovascular prevention, to further advice the composition of a particularly healthy diet. The present review summarizes recent studies on the endothelial effects of several nutraceuticals, that have been

Full Text Available Smoking, physical inactivity, and poor diet, along with obesity, fasting glucose and blood pressure have been independently associated with poorer cognitive performance. Few studies have related scales representing a combination of these variables to multiple domains of cognitive performance. The aim of this study was to investigate the association between overall cardiovascular health, incorporating seven components, and cognitive function.A cross-sectional analysis employing 972 participants, from the Maine-Syracuse Longitudinal Study was undertaken. Four health behaviors (body mass index, physical activity, diet, smoking and three health factors (total cholesterol, blood pressure, and fasting plasma glucose were measured. Each was categorized according to the American Heart Association definitions for ideal cardiovascular health, except diet, for which two food scores were calculated. A Cardiovascular Health Score was determined by summing the number of cardiovascular metrics at ideal levels. Cognitive function was assessed using a thorough neuropsychological test battery.Cardiovascular Health Score was positively associated with seven out of eight measures of cognitive function, with adjustment for age, education, and gender. With further adjustment for cardiovascular and psychological variables, these associations remained significant for Visual-Spatial Memory, Working Memory, Scanning and Tracking, Executive Function and the Global Composite score (p<0.05 for all. Ideal levels of a number of health factors and behaviors were positively associated with global cognitive performance.Increasing cardiovascular health, indexed by a higher number of metrics at ideal levels, is associated with greater cognitive performance. Smoking, physical activity, and diet are important components of cardiovascular health that impact upon cognition.

Background Depressed older individuals have a higher mortality than older persons without depression. Depression is associated with physical inactivity, and low levels of physical activity have been shown in some cohorts to be a partial mediator of the relationship between depression and cardiovascular events and mortality. Methods A cohort of 5888 individuals (mean 72.8±5.6 years, 58% female, 16% African-American) from four US communities was followed for an average of 10.3 years. Self-reported depressive symptoms (10-item Center for Epidemiological Studies Depression Scale) were assessed annually and self-reported physical activity was assessed at baseline and at 3 and 7 years. To estimate how much of the increased risk of cardiovascular mortality associated with depressive symptoms was due to physical inactivity, Cox regression with time-varying covariates was used to determine the percentage change in the log HR of depressive symptoms for cardiovascular mortality after adding physical activity variables. Results At baseline, 20% of participants scored above the cut-off for depressive symptoms. There were 2915 deaths (49.8%), of which 1176 (20.1%) were from cardiovascular causes. Depressive symptoms and physical inactivity each independently increased the risk of cardiovascular mortality and were strongly associated with each other (all pphysical inactivity had greater cardiovascular mortality than those with either individually (pPhysical inactivity reduced the log HR of depressive symptoms for cardiovascular mortality by 26% after adjustment. This was similar for persons with (25%) and without (23%) established coronary heart disease. Conclusions Physical inactivity accounted for a significant proportion of the risk of cardiovascular mortality due to depressive symptoms in older adults, regardless of coronary heart disease status.

Evaluation of knowledge to the subject of legal highs and popularity of their use amongst secondary-school students from the Silesian Voivodeship. Studies were conducted in spring of 2016 in two randomly selected secondary schools in Katowice and Dąbrowa Górnicza. The survey was carried out amongst students of these schools and concerned question about the knowledge of legal highs effect on the body and their use by young people. The study consisted of 336 questionnaire forms, 159 filled by secondaryschool students from Katowice and 177 by secondary-school students from Dąbrowa Górnicza. Legal highs for 78.3% of young people are as dangerous as drugs. Almost 70% of respondents believe that legal highs strongly affected the physical health, psyche, may cause a loss of life or health, as well as cause addiction. As the main effects of legal highs, young people point to strong agitation and aggression, as well as visions and hallucinations. 12.5% of respondents answered “Yes” to the question, whether they ever took legal highs. Most of students (69.7%) think that legal highs should be forbidden. The use of legal highs declared 12.5% of secondaryschool students. Most of respondents are aware of threats to health associated with use of legal highs.

The purpose of the Finnish Cardiovascular Study (FINCAVAS) is to construct a risk profile – using genetic, haemodynamic and electrocardiographic (ECG) markers – of individuals at high risk of cardiovascular diseases, events and deaths. All patients scheduled for an exercise stress test at Tampere University Hospital and willing to participate have been and will be recruited between October 2001 and December 2007. The final number of participants is estimated to reach 5,000. Technically successful data on exercise tests using a bicycle ergometer have been collected of 2,212 patients (1,400 men and 812 women) by the end of 2004. In addition to repeated measurement of heart rate and blood pressure, digital high-resolution ECG at 500 Hz is recorded continuously during the entire exercise test, including the resting and recovery phases. About 20% of the patients are examined with coronary angiography. Genetic variations known or suspected to alter cardiovascular function or pathophysiology are analysed to elucidate the effects and interactions of these candidate genes, exercise and commonly used cardiovascular medications. FINCAVAS compiles an extensive set of data on patient history, genetic variation, cardiovascular parameters, ECG markers as well as follow-up data on clinical events, hospitalisations and deaths. The data enables the development of new diagnostic and prognostic tools as well as assessments of the importance of existing markers

With increasing use of pediatric cardiovascular MRI, it is important for all imagers to become familiar with the spectrum of non-cardiovascular imaging findings that can be encountered. This study aims to ascertain the prevalence and nature of these findings in pediatric cardiovascular MRIs performed at our institution. We retrospectively evaluated reports of all cardiovascular MRI studies performed at our institute from January 2008 to October 2012 in patients younger than18 years. Most studies (98%) were jointly interpreted by a pediatric cardiologist and a radiologist. We reviewed the electronic medical records of all cases with non-cardiovascular findings, defined as any imaging finding outside the cardiovascular system. Non-cardiovascular findings were classified into significant and non-significant, based on whether they were known at the time of imaging or they required additional workup or a change in management. In 849 consecutive studies (mean age 9.7 ± 6.3 years), 145 non-cardiovascular findings were found in 140 studies (16.5% of total studies). Overall, 51.0% (74/145) of non-cardiovascular findings were in the abdomen, 30.3% (44/145) were in the chest, and 18.6% (27/145) were in the spine. A total of 19 significant non-cardiovascular findings were observed in 19 studies in individual patients (2.2% of total studies, 47% male, mean age 5.9 ± 6.7 years). Significant non-cardiovascular findings included hepatic adenoma, arterially enhancing focal liver lesions, asplenia, solitary kidney, pelvicaliectasis, renal cystic diseases, gastric distention, adrenal hemorrhage, lung hypoplasia, air space disease, bronchial narrowing, pneumomediastinum and retained surgical sponge. Non-cardiovascular findings were seen in 16.5% of cardiovascular MRI studies in children, of which 2.2% were clinically significant findings. Prevalence and nature of these non-cardiovascular findings are different from those reported in adults. Attention to these findings is important

Full Text Available The paper presents the results of investigations on the flora of fallow lands on rendzina soils. The research was carried out in the area of the Twardowice Plateau (the Silesian Upland within 9 areas adjacent to xerothermic grasslands. The investigated flora consisted of 220 vascular plant species with the dominance of native taxa. Plants of xerothermic grasslands and thermophilous edges were the most numerous (32%. The dominance of Libanotis pyrenaica in 4 of the examined areas should be emphasized. The percentage of meadow species was also considerable (25%. Anthropophytes comprised 18% of the flora of fallow lands and archaeophytes prevailed among them (9%. Solidago canadensis, an invasive species, was the constant component of the investigated fallows and sometimes its coverage was remarkable. As a result of the high proportion of xerothermic and thermophilous plants, plants associated with dry soils and soils having an intermediate character between dry and fresh, as well as plants preferring slightly acidic to alkaline soils poor in nitrogen compounds predominated in the investigated fallows. Perennial plants prevailed (65% in the studied flora and slightly more than half of the species reproduced only by seeds. Competitive plant species (C strategists had the highest proportion (39% and species with intermediate strategies CSR, CR and CS were also numerous. The investigations have shown that there are favourable conditions for settling and growth of many xerothermic species in the investigated fallow lands. Moreover, the neighbouring grasslands are the seed source for these areas.

Crichton, Georgina E; Elias, Merrill F; Robbins, Michael A

2014-01-01

Ideal cardiovascular health is a recently defined construct by the American Heart Association (AHA) to promote cardiovascular disease reduction. Arterial stiffness is a major risk factor for cardiovascular disease. The extent to which the presence of multiple prevalent cardiovascular risk factors and health behaviors is associated with arterial stiffness is unknown. The aim of this study was to examine the association between the AHA construct of cardiovascular health and arterial stiffness, as indexed by pulse wave velocity and pulse pressure. The AHA health metrics, comprising of four health behaviors (smoking, body mass index, physical activity, and diet) and three health factors (total cholesterol, blood pressure, and fasting plasma glucose) were evaluated among 505 participants in the Maine-Syracuse Longitudinal Study. Outcome measures were carotid-femoral pulse wave velocity (PWV) and pulse pressure measured at 4 to 5-year follow-up. Better cardiovascular health, comprising both health factors and behaviors, was associated with lower arterial stiffness, as indexed by pulse wave velocity and pulse pressure. Those with at least five health metrics at ideal levels had significantly lower PWV (9.8 m/s) than those with two or less ideal health metrics (11.7 m/s) (P<0.001). This finding remained with the addition of demographic and PWV-related variables (P=0.004). PMID:24384629

A long-term follow-up investigation of cardiovascular disease was organized primarily as an intensive substudy of the ABCC-JNIH Adult Health Study and secondarily for epidemiologic comparison with data on the Framingham, Massachusetts, population. One of the purposes of the present cardiovascular studies on a Hiroshima population was to obtain data comparable with that of the Framingham Study. An equally important aspect of the Hiroshima study is to explore radiation effects on the cardiovascular system. The sample is the Adult Health Study population and consists of 13,000 males and females in Hiroshima. This report provides the prevalence of cardiovascular disease in the first cross-section examined during 1958-1960 together with certain information on related factors. The overall attrition rate was 25%; 15% was caused by death or migration before the examination and 10% by refusal to participate. No significant difference was found in the blood pressure levels between the nonrespondents and the respondents in comparison with results of prior examinations at ABCC. The prevalence of various cardiovascular diseases was analyzed by sex and age. The analysis also extended to relationship of blood pressure, serum cholesterol, body weight, heart size, and occupation, with the prevalence of coronary heart disease for the sample over 40 years of age. 12 references, 15 tables.

Full Text Available BACKGROUND Present study “Cardiovascular Causes of Sudden Death- An Autopsy Study” was a cross-sectional study conducted in Department of Forensic Medicine, Government Medical College, Kottayam, during the time period from June 1 st 2013 to June 1 st 2014. The objective of the study was to find out the cardiovascular causes of sudden deaths and to correlate the postmortem findings with the histopathological examination. 57 cases brought for postmortem examination with history suggestive of sudden natural death were taken into the study and those cases observed to have a cardiovascular cause of sudden death during autopsy were further examined and their heart specimens were subjected to histopathological examination. Then, the sociodemographic factors, postmortem findings and histopathological findings were correlated and analysed. MATERIALS AND METHODS 57 cases brought for autopsy at Department of Forensic Medicine, Government Medical College, Kottayam from 01.06.2013 to 31.05.2014 were autopsied and subjected to histopathological examination of the heart. The socio-demographic data were collected; they were analyzed and correlated with the postmortem and histopathological findings. RESULTS Out of the 57 subjects who were taken into the study, maximum number of Sudden natural deaths were in the 36-50 year age group (42.2%, 33.3% in the 51-65 year age group and 14% of cases were in the 66-80 year age group. CONCLUSION Histopathological examination of the samples showed myocardial infarction in 33.3% of cases; chronic ischaemic heart disease in 56.1% of cases and myocarditis in 19.3% of cases. The major cardiovascular cause of sudden death was ascertained as Coronary artery disease.

Full Text Available Objective: Cardiac diseases are psycho-somatic disorders, and psychological aspects play an essential role in their initiation and exacerbation. The aim of this study was to gain appropriate knowledge in the epidemiology of co-morbid depression and anxiety disorder in cardiovascular outpatients.Method: This study is descriptive with a sample of patients attending a cardio-vascular clinic. 238 individuals were included in this study using a consecutive sampling method. The study instrument was Hospital Anxiety and Depression Scale (HADS questionnaire, which is a clinical scale for assessing anxiety and depression.Results: Of the 238 participants in this study, 93(38.7% were male and 146 (61.3% female. 28.5% of patients suffered from anxiety disorders , and 41.9% had depression. Regarding comorbid diseases such as diabetes mellitus, hyperlipidemia and hypertension, the severity of depression was just related to hypertension. There was a meaningful relationship between gender and symptoms of anxiety so that symptoms were more severe in women. Conclusion: Considering the high prevalence of depression and anxiety in patients suffering from cardio-vascular diseases, it is necessary to screen psychological disorders in patients with cardio-vascular diseases and improve their cardio-vascular health and quality of life as mush as possible.

Full Text Available Human activity is a factor strongly influencing the current state of vegetation. The abandonment of traditional land use enables uncontrolled secondary succession. Libanotis pyrenaica, a host plant for Orobanche bartlingii, is a great example of species that spread as a result of this process, especially in the area of the Silesian-Cracow Upland. The aim of this study is to show that the expansion of L. pyrenaica caused by changes in land use promotes spreading of O. bartlingii - a species rare in Poland and Europe. During the field research conducted in the last decade, further localities of O. bartlingii were found. The gathered data were summarized to supplement the known distribution of the species and to present floristic and ecological characteristics of the phytocenoses with the participation of L. pyrenaica and O. bartlingii.

Full Text Available The paper analyses the anthropogenic change in water bodies in the southern part of the Silesian Upland as exemplified by the town of Knurów. The assessment was based on topographic maps from the years 1827-1828, 1928-1936, 1960 and 1993, and on a 2011 orthophotomap. The cartographic materials used were processed as required for analysis purposes. Maps were calibrated in the Quantum GIS program on the basis of map corner coordinates and using the common points method. In Knurów, four main types of water bodies were distinguished with respect to their origins: reservoirs impounded by dams, flooded mineral workings, industrial water bodies and water bodies in subsidence basins and hollows. Historically, the first water bodies to appear were reservoirs impounded by dams, which dominated until the 1930s. They later fell into disuse and were completely dismantled. Water bodies in mineral workings formed in the early 20th century and were associated with the excavation of raw materials for producing bricks. The period of their greatest significance were the 1960s, when they constituted slightly more than 46% of water bodies in total and accounted for nearly 40% of overall surface area. At the end of the 19th and at the beginning of the 20th century, industrial reservoirs began to appear. Within the town of Knurów, those were sedimentation tanks that held mine water, washery effluent, backfill and cooling water, fire-fighting water pools and tanks, tanks at sewage treatment plants, industrial water tanks and others. Presently, these account for 41.4% (29 of the total number of water bodies and have a total surface area of 32.0 ha (25,2%. Within the study area, water bodies in subsidence basins and hollows only began to form in the second half of the 20th century. In 2011, such water bodies numbered 38 (54.3% and occupied an area of 90.4 ha (71.2%.

TRIGLYCERIDES, ATHEROSCLEROSIS, AND CARDIOVASCULAR OUTCOME STUDIES: FOCUS ON OMEGA-3 FATTY ACIDS.

Handelsman, Yehuda; Shapiro, Michael D

2017-01-01

To provide an overview of the roles of triglycerides and triglyceride-lowering agents in atherosclerosis in the context of cardiovascular outcomes studies. We reviewed the published literature as well as ClinicalTrials.gov entries for ongoing studies. Despite improved atherosclerotic cardiovascular disease (ASCVD) outcomes with statin therapy, residual risk remains. Epidemiologic data and recent genetic insights provide compelling evidence that triglycerides are in the causal pathway for the development of atherosclerosis, thereby renewing interest in targeting triglycerides to improve ASCVD outcomes. Fibrates, niacin, and omega-3 fatty acids (OM3FAs) are three classes of triglyceride-lowering drugs. Outcome studies with triglyceride-lowering agents have been inconsistent. With regard to OM3FAs, the JELIS study showed that eicosapentaenoic acid (EPA) significantly reduced major coronary events in statin-treated hypercholesterolemic patients. Regarding other agents, extended-release niacin and fenofibrate are no longer recommended as statin add-on therapy (by some guidelines, though not all) because of the lack of convincing evidence from outcome studies. Notably, subgroup analyses from the outcome studies have generated the hypothesis that triglyceride lowering may provide benefit in statin-treated patients with persistent hypertriglyceridemia. Two ongoing OM3FA outcome studies (REDUCE-IT and STRENGTH) are testing this hypothesis in high-risk, statin-treated patients with triglyceride levels of 200 to 500 mg/dL. There is consistent evidence that triglycerides are in the causal pathway of atherosclerosis but inconsistent evidence from cardiovascular outcomes studies as to whether triglyceride-lowering agents reduce cardiovascular risk. Ongoing outcomes studies will determine the role of triglyceride lowering in statin-treated patients with high-dose prescription OM3FAs in terms of improved ASCVD outcomes.

2014-01-01

Background Recently attention has been drawn to the health impacts of time spent engaging in sedentary behaviors. No studies have examined sedentary behaviors in relation to the newly defined construct of ideal cardiovascular health, which incorporates three health factors (blood pressure, total cholesterol, fasting plasma glucose) and four behaviors (physical activity, smoking, body mass index, diet). The purpose of this study was to examine associations between sedentary behaviors, including sitting time, and time spent viewing television and in front of a computer, with cardiovascular health, in a representative sample of adults from Luxembourg. Methods A cross-sectional analysis of 1262 participants in the Observation of Cardiovascular Risk Factors in Luxembourg study was conducted, who underwent objective cardiovascular health assessments and completed the International Physical Activity Questionnaire. A Cardiovascular Health Score was calculated based on the number of health factors and behaviors at ideal levels. Sitting time on a weekday, television time, and computer time (both on a workday and a day off), were related to the Cardiovascular Health Score. Results Higher weekday sitting time was significantly associated with a poorer Cardiovascular Health Score (p = 0.002 for linear trend), after full adjustment for age, gender, education, income and occupation. Television time was inversely associated with the Cardiovascular Health Score, on both a workday and a day off (p = 0.002 for both). A similar inverse relationship was observed between the Cardiovascular Health Score and computer time, only on a day off (p = 0.04). Conclusion Higher time spent sitting, viewing television, and using a computer during a day off may be unfavorably associated with ideal cardiovascular health. PMID:24925084

Full Text Available At the beginning of this century, particularly after 2003, decline of Picea abies occurred at Forest District Jablunkov in the Silesian Beskids. This decline is of the complex character disease caused by the synergetic effects of abiotic, biotic and anthropogenic factors. Under conditions of climatic changes, it is possible to expect that similar episodes will repeat and appear also in other regions. Forestry will have to respond to them by changes in forest management. Measures proposed and discussed in this paper can be a starting point in their basic principles for other similar regions. Fundamental spheres of possible measures are as follows: chemical adaptations of the soil environment, i.e. liming or fertilization (if to realise them or not, changes in the species composition (particularly the rate of the decrease of Picea abies, participation of Fagus sylvatica and increasing the diversity of tree species, modification of the rotation (decrease and regeneration period (increase.

Full Text Available Introduction. Population increasingly draws attention to the issues concerning the environment degraded by the progress of civilization and the impact of this process on health. However, public awareness of the risk exposure to indoor contaminants is lagging a long way behind knowledge regarding outdoor environmental hazards. The aim of the study was to assess the risk perception related to exposure to indoor environmental factors in the population of Silesia. Materials and methods. In this study the electronic version of a questionnaire survey – downloaded on the website www.moja-ankiety.pl. was used. During the 3-months duration of the project 552 subjects participated in the survey. In the study participated the Silesian Voivodeship inhabitants such as chat rooms users, newsgroups and online forum participants. Data analysis was performed by using statistical program – STATA Version 8 SE [9], where the Kruskall-Wallis test and χ2 test were applied. Statistical significance was assessed at p value *0.05. Results. Despite the low perception of environmental health hazards inside the dwellings, the majority of respondents were able to indentify health effects and ways to reduce exposure to indoor air pollution. Both gender, place of residence, education level and age significantly affected the level of perception of respondents on the risk connected with exposure to indoor air pollution. Conclusion. It is necessary to continuously work on raising public awareness of environmental health hazards in confined spaces, the causes of their occurrence, types, effects and above all the ways to counter these threats.

Full Text Available The purpose of the present study was to examine how obesity and cardiovascular fitness are associated with the inhibition aspect of executive function from behavioral and electrophysiological perspectives. One hundred college students, aged 18 to 25 years, were categorized into four groups of equal size on the basis of body mass index and cardiovascular fitness: a normal-weight and high-fitness (NH group, an obese-weight and high-fitness (OH group, a normal-weight and low-fitness (NL group, and an obese-weight and low-fitness (OL group. Behavioral measures of response time and number of errors, as well as event-related potential (ERP measures of P3 and N1, were assessed during the Stroop Task. The results revealed that, in general, the NH group exhibited shorter response times and larger P3 amplitudes relative to the OH, NL, and OL groups, wherein the OL group exhibited the longest response time in the incongruent condition. No group differences in N1 indices were also revealed. These findings suggest that the status of being both normal weight and having high cardiovascular fitness is associated with better behavioral and later stages of electrophysiological indices of inhibition. However, these benefits in inhibition function would be lost in an individual who is obese or has low cardiovascular fitness, reflecting the importance keeping both normal weight and having high cardiovascular fitness.

Biomarkers for predicting cardiovascular events in community-based populations have not consistently added information to standard risk factors. A limitation of many previously studied biomarkers is their lack of cardiovascular specificity. To determine the prognostic value of 3 novel biomarkers induced by cardiovascular stress, we measured soluble ST2, growth differentiation factor-15, and high-sensitivity troponin I in 3428 participants (mean age, 59 years; 53% women) in the Framingham Heart Study. We performed multivariable-adjusted proportional hazards models to assess the individual and combined ability of the biomarkers to predict adverse outcomes. We also constructed a "multimarker" score composed of the 3 biomarkers in addition to B-type natriuretic peptide and high-sensitivity C-reactive protein. During a mean follow-up of 11.3 years, there were 488 deaths, 336 major cardiovascular events, 162 heart failure events, and 142 coronary events. In multivariable-adjusted models, the 3 new biomarkers were associated with each end point (Pstatistic (P=0.005 or lower) and net reclassification improvement (P=0.001 or lower). Multiple biomarkers of cardiovascular stress are detectable in ambulatory individuals and add prognostic value to standard risk factors for predicting death, overall cardiovascular events, and heart failure.

Latin America is undergoing the epidemiologic transition that occurred earlier in developed countries, and is likely to face a gigantic epidemic of heart disease in the next few years unless urgent action is taken. The first essential component of any effective cardiovascular disease (CVD) control program is to establish reliable estimates of cardiovascular disease-related morbidity and mortality. However, such data from population-based studies in Latin America are still lacking. In this paper, we present the design and operation of PREVENCION (Estudio Peruano de Prevalencia de Enfermedades Cardiovasculares, for Peruvian Study of the Prevalence of Cardiovascular diseases). PREVENCION is an ongoing population-based study on a representative sample of the civilian non-institutionalized population of the second largest city in Peru. Its population is comparable to the rest of the Peruvian urban population and closely resembles other Latin American populations in countries such as Bolivia and Ecuador. Our study will contribute to the enormous task of understanding and preventing CVD in Latin America.

Recent findings indicate that patients with systemic sclerosis have an increased risk of cardiovascular disease. To determine whether patients with systemic sclerosis or localized scleroderma are at increased risk of cardiovascular disease, a cohort study of the entire Danish population aged ≥ 18 and ≤ 100 years was conducted, followed from 1997 to 2011 by individual-level linkage of nationwide registries. Multivariable adjusted Cox regression models were used to estimate the hazard ratios (HRs) for a composite cardiovascular disease endpoint. A total of 697 patients with localized scleroderma and 1,962 patients with systemic sclerosis were identified and compared with 5,428,380 people in the reference population. In systemic sclerosis, the adjusted HR was 2.22 (95% confidence interval 1.99-2.48). No association was seen between patients with localized scleroderma and cardiovascular disease. In conclusion, systemic sclerosis is a significant cardiovascular disease risk factor, while patients with localized scleroderma are not at increased risk of cardiovascular disease.

Full Text Available A land use regime undergoes much change over time depending on the growth in the importance of various interest groups. Spatial conflicts repeatedly accompany this growth. The aim of the article is to determine the relationship between spatial conflicts and landscape changes. On the basis of the Silesian and Żywiec Beskid mountain ranges, it has been proven that conflicts arising between mountain grazing, agriculture, forest management, contemporary building and tourism development have significant impacts on the landscape. To this end, archive and contemporary cartographic materials, historical scientific works and archive photographs were used. The conflicts between mountain grazing and other types of human activity in the study area were analysed. Subsequently, their influence on the landscape was determined. As a result of the study, the primary sources of conflicts were indicated and correlated with historical periods and the predominant landscape use regime. The imprints of historical space conflicts and the rivalry for land use between different entities for their own purposes are still visible in the landscape. The historical conflicts have arisen between entities seeking ways to use different environmental resources occurring in the same area. Contemporary conflicts arise between entities seeking ways to use environmental resources (tourism and between entities conscious of the hazards of the landscape sustainability resulting from the utilization of environmental resources (nature conservation services. Both historical and contemporary conflicts usually have a violent course resulting from the lack, or deficiency of, legislation concerning land management.

To assess absolute cardiovascular risk and co-morbidities in uncontrolled hypertensive patients (blood pressure [BP]>or=140/90 mmHg or>or=130/80 mmHg in diabetics) attending Primary Care Physicians in Spain, and to determine the attitudes of these physicians towards this problem. Cross-sectional, multicenter study involving 356 general practitioners around Spain. Absolute cardiovascular risk was assessed according to ESH-ESC 2003 Guidelines in a sample of 1,710 patients. Two hundred ninety seven patients were excluded by several reasons and a total of 1,413 hypertensive patients were valuable (mean age: 65.3+/-11.4 years; 56.7% women). Normal BP values (or=180/110 mmHg) by 7.9%. Associated cardiovascular risk factors were observed in 96.0% of patients (95% CI=94.7-97.2%), target organ damage in 34.5% (95% CI=31.6-36.5%), and cardiovascular clinical disease in 36.0% (95% CI=33.5-38.5%). According to ESH-ESC 2003 Guidelines 34.0% (CI=31.5-38.2%) were at very-high risk; 29.4% (95% CI=26.4-32.8%) at high risk; 30.4% (95% CI=27.2-33.7%) at moderate risk and 5.4% (95% CI=3.9-7.2%) at low risk of cardiovascular disease. Despite the high absolute risk, physicians did not do any therapeutic change in 30.4% (95% CI=28.2-33.5%) of uncontrolled hypertensive patients. Most of them (64.26%) considered that bad compliance to life style changes was the reason for inadequate BP control. The most frequent measure introduced was the association of additional drugs. Absolute cardiovascular risk in uncontrolled hypertensive patients attending Primary Care Physicians in Spain is very relevant. Sixty-five percent of these patients are at high or very high risk with a high prevalence of target organ damage or associated cardiovascular clinical disease. Therapeutic attitudes towards these patients are still very conservative although they are improving compared with previous studies.

Non-therapeutic use of anabolic androgenic steroids (AAS) has been associated with various adverse effects; one of the most serious being direct cardiovascular effects with unknown long-term consequences. Therefore, large studies of the association between AAS and cardiovascular outcomes are warranted. We investigated cardiovascular morbidity and mortality in individuals who tested positive for AAS. Between 2002 and 2009, a total of 2013 men were enrolled in a cohort on the date of their first AAS test. Mortality and morbidity after cohort entry was retrieved from national registries. Of the 2013 individuals, 409 (20%) tested positive for AAS. These men had twice the cardiovascular morbidity and mortality rate as those with negative tests (adjusted hazard ratio (aHR) 2.0; 95% confidence interval (CI) 1.2-3.3). Compared to the Swedish population, all tested men had an increased risk of premature death from all causes (standardized mortality ratio for AAS-positive: 19.3, 95% CI 12.4-30.0; for AAS-negative: 8.3, 95% CI 6.1-11.0). Non-therapeutic exposure to AAS appears to be an independent risk factor for cardiovascular morbidity and premature death. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Full Text Available The aim of the paper was to identify the present situation in innovation policies of small and medium-sized enterprises in the South Moravian and Moravian Silesian regions. In order to achieve the specified objective, quantitative research was carried out in the small and medium-sized enterprises by way of questionnaires. The achieved results imply that the enterprises under investigation apply competitive strategy focusing on top quality of goods on offer. The research manifested that the companies focused markedly on innovations in supplying products on offer with additional functions or features. The research results show that the companies do not conduct changes in production organization frequently, not even following their earlier innovative activities. The results of the research into the innovative activity “change in product design” imply that this activity is not applied frequently in comparison with the above-mentioned activities. Based on the interviewed companies' weak points in human resources, the elementary drawbacks include lack of management's command of foreign languages as well as production staff's expert skills. The results of the research imply that the interviewed companies perceive the sphere of products (improved product quality, extension of a product range, the sphere of new technologies and the sphere of an increase in market potential as the most significant. The questionnaire inquiry shows that innovative and development activities are most frequently financed from companies' own funds, subsidies/grants, bank credits and leases. Mortgages and venture capital are only made used of occasionally.

Full Text Available Background: Overdoses with cardiovascular drugs are related with significant morbidity and mortality. Beta-adrenergic blockers, calcium-channel blockers (CCBs, thiazide, digoxin and angiotensin converting enzyme (ACE inhibitors represent five of the most important classes of cardiovascular drugs. Overdoses with cardiovascular drugs are typically caused by exploratory ingestion by children or intentional ingestion by suicidal adults. As no study has been performed about poisoning with this kind of drug in Khuzestan, this study aimed to investigate the frequency of cardiovascular drug poisoning and its clinical features in patients presenting in Razi Hospital of Ahvaz from 2005 to 2009. Methods: A retrospective review of medical records of patients poisoned with cardiovascular who were treated at Clinical Toxicology Department was executed. A total of 70 poisoning cases referred to Razi Hospital were identified. These unselected cases included intentional, accidental, criminal and occupational circumstances. Beta-blocker poisoning, digital poisoning, calcium-channel blockers poisoning, ACE inhibitor poisoning, thiazide poisoning and poisoning with other cardiovascular drugs were evaluated on the basis of recorded data. Poisoning with one or several agents, time of admission, type of poisoned agents, sex, age, therapeutic intervention and mortality were investigated. Results: This study revealed that most of the people poisoned with cardiovascular drugs were females, single people and urban population. Most of the patients were 15-25 years old. Most poisoning was with beta blocker and calcium channel blockers. Their first symptom was headache and most of them needed ICU admission. Most of the patient ECGs were normal. There were 2 cases of death. Conclusion: This study revealed that continuous health care and the administration of the exact dose of drugs in the appropriate time and also developing of the toxicology centers seem necessary.

The prognosis in rectal cancer has improved significantly with the introduction of total mesorectal excision (TME). Therapeutic results have also improved in Poland, but the survival rates are still lower and local recurrences more frequent when compared to western countries. The aim of this study was to show that, unless improperly performed, TME might significantly improve the results of oncological treatment throughout Poland. The clinical records of 370 rectal cancer patients treated surgically at Lower Silesian Oncology Center, Wroclaw between April 1 st , 1998, and May 6 th , 2004 were subjected to retrospective analysis. The material was divided into two groups on the basis of the surgical procedure emploved: 1) TME (n=260, 70%) another (undefined) technique (n=110, 30%). The following parameters were compared between both groups: 1) the percentage of one- and five-year observed survivals, 2) the average time of survival during the initial year surgery (in months), 3) the average time of survival during five years following surgery (in years), 4) the percentage of five-year relative survivals, and 5) the percentage of isolated local recurrences demonstrated during five years following the surgery. The study has shown that both the average survival times during a five-year follow-up and rates of five-year relative survival were significantly better in the series of TME-operated patients, as compared to those who underwent other type of rectal surgery. Fifty-seven patients who underwent TME had achieved five year survival, which corresponds to 63.3% and 81.6% of observed and relative survivals, respectively. In contrast, in the group operated by a non-TME technique, the percentages of observed and relative five year survival amounted to 36.7% and 45.5%, respectively. Moreover, isolated local recurrence developed in 6.7% of the TME-treated patients only, which contrasted with 23% observed in the group in which the old approach was used. Our study proves that

To estimate the prevalence of cardiovascular diseases, cardiovascular risk factors, and the psychosocial characteristics associated with them in an urban population aged 65 years and older. Descriptive cross-sectional study of the population. City of Salamanca (Spain). A total of 480 participants aged 65 and older were selected using a stratified randomized sampling method. A health questionnaire was completed in the participants' homes. Weight, height, waist circumference, arterial pressure, blood glucose and cholesterol, were measured, and the standardized prevalence for a European population was estimated. A total of 327 participants were interviewed (68.10% of those selected), mean age of participants was 76 (SD: 7.33). Of the total, 64.5% were women and 20.2% (15.8-24.5) had some cardiovascular disease. In males, the most prevalent cardiovascular disease was ischemic heart disease (12.1% [6.1-18]), while in females it was heart failure (10.4% [6.3-14.6]). Hypertension was the most frequent cardiovascular risk factor for males (63.8% [53.2-70.9]) and females (69.7%.[63.5-75.9]), followed by diabetes in males (36.2% [27.5-45]), and sedentary lifestyle in females (36.0% [29.5-42.5]). Those with cardiovascular diseases were more dependent and had a worse prognosis (Charlson's Comorbility Index). Ischemic heart disease is the most prevalent heart disease in males, while heart failure is the most prevalent disease for females. Almost 80% of the population aged 65 and older did not suffer any of the three cardiovascular diseases that are the main causes of mortality in this group of age. Participants who had a CVD were more dependent for activities of daily living. Copyright © 2012 Elsevier España, S.L. All rights reserved.

Full Text Available Ageing is associated with changes at the molecular and cellular level that can alter cardiovascular function and ultimately lead to disease. The baboon is an ideal model for studying ageing due to the similarities in genetic, anatomical, physiological and biochemical characteristics with humans. The aim of this cross-sectional study was to investigate the changes in cardiovascular profile of baboons over the course of their lifespan.Data were collected from 109 healthy baboons (Papio hamadryas at the Australian National Baboon Colony. A linear regression model, adjusting for sex, was used to analyse the association between age and markers of ageing with P 12 years had significantly shorter telomeres when compared to younger (<3 years baboons (P = 0.001.This study is the first to demonstrate that cardiovascular function alters with age in the baboon. This research identifies similarities within cardiovascular parameters between humans and baboon even though the length of life differs between the two species.

The subject of the study covered volatile ashes created during hard coal burning process in ash furnaces, in power plants operating in the Upper Silesian Industrial Region, Southern Poland. Coal-fired power plants are furnished with dust extracting devices, electro precipitators, with 99-99.6% combustion gas extracting efficiency. Activity concentrations ofTh-232, Ra-226, K-40, Ac-228, U-235 and U-238 were measured with gamma-ray spectrometer. Concentrations of selected rare soil elements (La, Ce, Nd, Sm, Y, Gd, Th, U) were analysed by means of instrumental neutron activation analysis (INAA). Mineral phases of individual ash particles were identified with the use of scanning electron microscope equipped with EDS attachment. Laser granulometric analyses were executed with the use of Analyssette analyser. The activity of the investigated fly-ash samples is several times higher than that of the bituminous coal samples; in the coal, the activities are: 226Ra - 85.4 Bq kg -1 , 40 K-689 Bq kg -1 , 232Th - 100.8 Bq kg -1 , 235U-13.5 Bq kg -1 , 238U-50 Bq kg -1 and 228Ac - 82.4 Bq kg -1 .

The cardiac and vascular late sequelae in long-term survivors of childhood cancer (CVSS)-study aimed to quantify the prevalence of cardiovascular risk factors (CVRF) and cardiovascular disease (CVD) in German childhood cancer survivors (CCS). In the CVSS-study (NCT02181049), 1002 CCS (age range 23-48 years) diagnosed with neoplasia prior to 15 years of age between 1980 and 1990 prospectively underwent a systematic, standardized clinical and laboratory cardiovascular screening, identical to the population-based Gutenberg Health Study (GHS) cohort. For 951 individuals, prevalences of CVRF and CVD were primarily compared to the GHS sample and to two further German population-based cohorts. Using log-binomial regression models, an increased risk for occurrence of arterial hypertension [relative risk (RR) 1.38, 95% confidence interval (95% CI 1.21-1.57)] and dyslipidaemia [RR 1.26 (95% CI 1.12-1.42)] was found. This indicates a premature occurrence compared to the general population of approximately 6 and 8 years, respectively [rate advancement period estimator, RAPhypertension 5.75 (95% CI 3.5-8.0) and RAPdyslipidaemia 8.16 (95% CI 4.4-11.9)]. Overall, no differences were observed for obesity and diabetes. Overt CVD was present in 4.5% (95% CI 3.0-6.6%) of CCS [RR 1.89 (95% CI 1.34-2.66), RAPCVD 7.9 (95% CI 4.1-11.7)], of which the most frequent entities were congestive heart failure and venous thromboembolism. Prevalences of CVRF and CVD increased with age without reaching a plateau over time. This large CCS screening examination revealed consistently in comparison to three population samples a considerably increased risk for premature CVD. The findings in these young adult CCS indicate a high burden of cardiovascular morbidity and mortality in the long term. NCT02181049.

To evaluate whether a multidisciplinary educational program (EP) in cardiovascular prevention (CVP) for children could improve the Framingham cardiovascular risk (FCR) of their parents after one year. This was a prospective community-based study in Brazil during 2010 that randomized students aged 6 to 10 years old to two different approaches to receiving healthy lifestyle information. The control group received written educational material (EM) for their parents about healthy lifestyle. The intervention group received the same EM for parents, and children were exposed to a weekly EP in CVP with a multidisciplinary health team. At onset and end of the study, we collected data from parents and children (weight, height, arterial blood pressure, and laboratory tests). We studied 197 children and 323 parents. Analyzing the parents' FCR we found that 9.3% of the control group and 6.8% of the intervention group had more than a 10% year risk of cardiovascular heart disease (CHD) over the next 10 years. After the children's EP for the year, the intervention group had a reduction of 91% in the intermediate/high FCR group compared with a 13% reduction in the control group, p = 0.002). In the same way, analyzing the FCR of all parents, there was a reduction of the average risk in the intervention group (3.6% to 2.8% respectively, p children can reduce the FCR risk of their parents, especially in the intermediate/high risk categories.

The purposes of this study were to translate current knowledge regarding cardiovascular risk factors, screening, and prevention to a disparate population of women and to ascertain the cardiovascular health status and risk factors in a sample of minority and underserved Appalachian women. Demographic data were collected from a voluntary sample of women from a disparate population living in Appalachian Tennessee. A coronary risk profile recorded family health history, personal health history, and lifestyle habits affecting risk for cardiovascular disease. Physiologic measurements included body mass index, blood pressure, fasting glucose, cholesterol levels, ankle brachial index, and carotid artery stenosis. Women in Appalachia Tennessee from a disparate population have high risks for heart disease and stroke. This is a critical time to address any modifiable risk factors and aggressively treat underlying cardiovascular diseases such as hypertension and hypercholesterolemia. Nurse practitioners (NPs) often provide primary care to women who may not be aware of their cardiovascular risks or actual disease. NPs can ensure that their practice incorporates primary and secondary cardiovascular prevention through screening, individual health education, and aggressive evidence-based treatment plans for women.

Cardiovascular risk and subclinical cardiovascular disease in polycystic ovary syndrome.

In addition to its effects on reproductive health, it is now well recognized that polycystic ovary syndrome (PCOS) is a metabolic disorder, characterized by decreased insulin sensitivity which leads to an excess lifetime risk of type 2 diabetes and cardiovascular disease. PCOS patients are often obese, hypertensive, dyslipidemic and insulin resistant; they have obstructive sleep apnea and have been reported to have higher aldosterone levels in comparison to normal healthy controls. These are all components of an adverse cardiovascular risk profile. Many studies exploring subclinical atherosclerosis using different methods (flow-mediated dilatation, intima media thickness, arterial stiffness, coronary artery calcification) as well as assessing circulating cardiovascular risk markers, point toward an increased cardiovascular risk and early atherogenesis in PCOS. The risk and early features of subclinical atherosclerosis can be reversed by non-medical (normalization of weight, healthy lifestyle) and medical (metformin, thiazolidinediones, spironolactone, and statins) interventions. However, the long-term risk for cardiovascular morbidity and mortality as well as the clinical significance of different interventions still need to be properly addressed in a large prospective study.

The role of anthropogenic water reservoirs within the landscapes of mining areas – a case study from the western part of the Upper Silesian Coal Basin

Directory of Open Access Journals (Sweden)

Jaruchiewicz Ewelina

2014-03-01

Full Text Available A few thousand anthropogenic water reservoirs can be found in the area of the Upper Silesian Coal Basis (USCB located in southern Poland. In this paper the role of such anthropogenic lakes in the landscape of the western part of the USCB was presented and illustrated with the example of Knurów, a mining city, and its immediate surrounding area. The study of landscape changes in this area was carried out on the basis of archival and contemporary cartographic materials, historical sources, and interviews with inhabitants and direct field observations. It was found that the origin of the majority of the water reservoirs is related to hard coal, clay and sand mining. They were created primarily as a result of filling subsidence basins and post-mining excavations with water, as well as being the result of the construction of various hydro-technical facilities (settling ponds, fire protection water reservoirs, etc. In the study area the anthropogenic water reservoirs are of different sizes, shapes and durability and play different roles in the environment. Between 1884 and 2001 their number increased 25-fold, while at the same time their total surface area increased more than 8-fold. The role of the newly created water reservoirs in the landscape primarily involves the transformation of the existing terrestrial ecosystems into wetland ecosystems. The agro-forestry landscape of the late 19th century was transformed into a typically anthropogenic landscape with a dominant share of water reservoirs, settlement ponds and mining waste heaps. The most common species of plants around the water reservoirs are Phragmites australis, Typha latifolia, Ceratophyllum demersum, Elodea canadensis, Potamogeton natans, Lemna sp., Acorus calamus, Myriophyllum verticillatum, Sagittaria sagittifolia, Alisma plantago-aquatica and Glyceria aquatica. The most valuable elements of the flora include Trapa natans and Ruppia maritima, species recognized in Poland as threatened

Izmajłowicz, Barbara; Kornafel, Jan; Błaszczyk, Jerzy

According to the definition by the International Agency for Research on Cancer (IARC), primary multiple neoplasms are two or more neoplasms of different histopathological build in one organ, or two or more tumors occurring in one patient, regardless of the time of their occurrence (synchronic - up to 6 months, metachronous - after 6 months), coming from an organ or a tissue and not being an infiltration from another neoplasm, a relapse or a metastasis. It was the aim of the study to analyze the frequency of the occurrence of multiple neoplasms among patients suffering from uterine cervix cancer, with a special interest in coexistent neoplasms, the time of their occurrence and total 5-year survivals. The data from the Lower Silesian Cancer Registry concerning the years 1984-2009 formed the material of the present study. 5.3% of all cervix neoplasms occurred as multiple cancers. Cervix neoplasms were 13.4% of multiple neoplasms. On average, cervical cancer occurred as a subsequent cancer in 6 patients yearly (60.7% of the occurrences of cervical cancer were in the period of 5 years following treatment for the first neoplasm). 5-year survival in patients suffering from primarily multiple cervix neoplasms constituted 57% and was convergent with the results for all patients suffering from cervical cancer. Cervical cancer as the first neoplasm occurred in 287 patients, on average in 11 patients annually. In the period of the first 5 years after the treatment of cervical cancer, there were 42.8% occurrences of other cancers. Cervical neoplasms most frequently coexisted with cancers of the breast, lung and large intestine. The frequency of the occurrence of multiple neoplasm among cervical cancer patients is increasing. Most frequently they coexist with other tobacco-related neoplasms, those related to HPV infections and with secondary post-radiation neoplasms. These facts should be taken into consideration during post-treatment observation and when directing diagnostic

Full Text Available Abstract Background It is desirable that those at highest risk of cardiovascular disease should have priority for preventive measures, eg. treatment with prescription drugs to modify their risk. We wanted to investigate to what extent present use of cardiovascular medication (CVM correlates with cardiovascular risk estimated by three different risk scores (Framingham, SCORE and NORRISK ten years ago. Methods Prospective logitudinal observational study of 20 252 participants in The Hordaland Health Study born 1950-57, not using CVM in 1997-99. Prescription data obtained from The Norwegian Prescription Database in 2008. Results 26% of men and 22% of women aged 51-58 years had started to use some CVM during the previous decade. As a group, persons using CVM scored significantly higher on the risk algorithms Framingham, SCORE and NORRISK compared to those not treated. 16-20% of men and 20-22% of women with risk scores below the high-risk thresholds for the three risk scores were treated with CVM, while 60-65% of men and 25-45% of women with scores above the high-risk thresholds received no treatment. Among women using CVM, only 2.2% (NORRISK, 4.4% (SCORE and 14.5% (Framingham had risk scores above the high-risk values. Low education, poor self-reported general health, muscular pains, mental distress (in females only and a family history of premature cardiovascular disease correlated with use of CVM. Elevated blood pressure was the single factor most strongly predictive of CVM treatment. Conclusion Prescription of CVM to middle-aged individuals by large seems to occur independently of estimated total cardiovascular risk, and this applies especially to females.

Metz-Flamant, C.; Bonaventure, A.; Tirmarche, M.; Laurier, D.; Bernier, M.O.; Milliat, F.

2009-01-01

Background While cardiovascular risks associated with high level of ionizing radiation are well-established, long-term effects of low and medium levels of exposure, between 0 and 5 gray (Gy), on the cardiovascular system are debated. Methods Available literature was reviewed considering various populations, such as survivors of atomic bombs, nuclear workers, Chernobyl liquidators, radiologists and radiological technologists and patients exposed for medical reasons. Results A significant increased risk of cardiovascular diseases associated with low doses of ionizing radiation was observed in 13 studies among the 27 analyzed. The ischemic heart diseases risk was detailed in 16 studies and seven of them showed a significant increase. The cerebrovascular risk was significantly increased in five studies among the 12 considered. Conclusion Some epidemiological and experimental data are clearly in favour of an increased cardiovascular risk associated with exposure to low doses. However, given the multi-factorial origin of cardiovascular diseases and the lack of a clear pathophysiologic mechanism, epidemiological results have to be carefully interpreted. Further research should be conducted in this area. (authors)

Postirradiation cardiovascular dysfunction

Cardiovascular dysfunction may be defined as the inability of any element of the cardiovascular system to perform adequately upon demand, leading to inadequate performance and nutritive insufficiency of various parts of the body. Exposure to supralethal doses of radiation (accidental and therapeutic) has been show to induce significant alterations in cardiovascular function in man. These findings indicate that, after irradiation, cardiovascular function is a major determinant of continued performance and even survival. For the two persons who received massive radiation doses (45 and 88 Gy, respectively) in criticality accidents, the inability to maintain systematic arterial blood pressure (AP) was the immediate cause of death. In a study of cancer patients given partial-body irradiation, two acute lethalities were attributed to myocardial infarction after an acute hypotensive episode during the first few hours postexposure. Although radiation-induced cardiovascular dysfunction has been observed in many species, its severity, duration, and even etiology may vary with the species, level of exposure, and dose rate. For this reason, our consideration of the effects of radiation on cardiovascular performance is limited to the circulatory derangements that occur in rat, dog, and monkey after supralethal doses and lead to radiation-induced cardiovascular dysfunction in these experimental models. The authors consider other recent data as they pertain to the etiology of cardiovascular dysfunction in irradiated animals

This paper is aimed to discuss the involvement of delayed radiation effects of A-bomb exposure in cardiovascular diseases. First, the relationship between radiation and cardiovascular diseases is reviewed in the literature. Animal experiments have confirmed the relationship between ionizing radiation and vascular lesions. There are many reports which describe ischemic heart disease, cervical and cerebrovascular diseases, and peripheral disease occurring after radiation therapy. The previous A-bomb survivor cohort studies, i.e., the RERF Life Span Study and Adult Health Study, have dealt with the mortality rate from cardiovascular diseases, the prevalence or incidence of cardiovascular diseases, pathological findings, clinical observation of arteriosclerosis, ECG abnormality, blood pressure abnormality, and cardiac function. The following findings have been suggested: (1) A-bomb exposure is likely to be involved in the mortality rate and incidence of ischemic heart disease and cerebrovascular diseases; (2) similarly, the involvement of A-bomb exposure is considered in the prevalence of the arch of aorta; (3) ECG abnormality corresponding to ischemic heart disease may reflect the involvement of A-bomb exposure. To confirm the above findings, further studies are required on the basis of more accurate information and the appropriate number of cohort samples. Little evidence has been presented for the correlation between A-bomb exposure and both rheumatic heart disease and congenital heart disease. (N.K.) 88 refs

Methamphetamine dependence is a major public health problem. This study examined the nature, and extent, of cardiovascular disease amongst cases of methamphetamine-related death in Australia, 2009-2015. Analysis of 894 cases of methamphetamine-related death with full autopsy reports retrieved from the National Coronial Information System. The mean age was 37.9yrs (range 15-69yrs) and 78.5% were male. A quarter (26.3%) of cases had enlarged hearts and left ventricular hypertrophy was diagnosed in 18.9%. Severe coronary artery disease was present in 19.0%, the left coronary artery being the vessel most frequently stenosed (16.6%). Replacement fibrosis (evidence of earlier ischaemic events) in the heart muscle was observed in 19.8% of cases, and cardiomyopathy was diagnosed in 5.5%. Histological evidence of hypertension was observed in 32.7% of cases. With the exception of cardiomyopathy, equally common amongst both sexes, cardiovascular disease was more common amongst males, and those aged >35yrs. Clinically significant levels of cardiovascular disease were also observed amongst cases where the cause of death was not attributed to cardiovascular disease: cardiomegaly (19.3%), left ventricular hypertrophy (14.6%), severe coronary artery disease (9.4%), replacement fibrosis (14.4%), cardiomyopathy (3.3%). Cardiovascular disease was highly prevalent, despite the relatively young age of cases. With methamphetamine use increasing rapidly in major regions, cardiovascular disease and cardiovascular-related death will likely increase amongst methamphetamine users.

To observe the cardiovascular emergencies which were most frequently treated and to quantify the drug utilization trends in the cardiovascular emergencies, in terms of the Defined Daily Doses [DDD] and the prescribing prevalence in the cardiovascular emergencies. This prescription based study was undertaken in the Medicine ICU of the government medical hospital. The age, sex, diagnosis (only cardiovascular) and the drugs which were prescribed, were recorded for each patient. Also, the brand names and the generic names of the prescribed drugs were noted. The collected data was analyzed to study the drug utilization trends. It was observed that the most commonly treated cardiovascular disease was IHD. The IHD was more in males than in females who were below 50 years of age and it was nearly equal in the age groups which were above 50 years. The use of Angiotensin Converting Enzyme (ACE) inhibitors was higher than that of the beta blockers and the calcium channel blockers. The patients with cardiovascular emergencies also had preceding associated diseases like diabetes mellitus and hypertension. The protocol of the management which was followed by the college in the treatment of cardiovascular emergencies was competent enough, as the clinical outcomes of the patients were favourable. But there was a guideline incongruent prescribing behaviour which was statistically significant, for which there is a need to undertake large scale studies.

Medical Tourism in Romania. The Case Study of Cardiovascular Rehabilitation in Covasna

Directory of Open Access Journals (Sweden)

Roxana Oana Darabont

2014-11-01

Full Text Available Romania has one of the highest mortality rates in Europe for ischemic heart disease and, especially, for cerebrovascular disease. Taking into account the actual prevalence of cardiovascular diseases, an augmentation of the demand for specialized medical services is expected. As this paper argues, this situation can have an important impact on medical tourism. We analyze original data on the case study of a hospital, specialized in cardiovascular treatment, in the Romanian county of Covasna, which is offering specific balneal procedures, such as CO2 .hydrotherapy, alongside regular rehabilitation programs. The aim of our study is to evaluate the demographic characteristics, and the pathology of the hospitalized patients, as well as the specific rehabilitation procedures. Our findings suggest that the interest of patients, with cardiovascular diseases, for medical tourism can be influenced by accessibility, by some particularities of the location, but also by the holistic nature of the rehabilitation procedures.

Considering the scarcity of health care resources and the high costs associated with cardiovascular diseases, we investigated the spending on cardiovascular primary preventive activities and the prescribing behaviour of primary preventive cardiovascular medication (PPCM) in Dutch family practices (FPs). A mixed methods design was used, which consisted of a questionnaire (n = 80 FPs), video recordings of hypertension- or cholesterol-related general practitioner visits (n = 56), and the database of Netherlands Information Network of General Practice (n = 45 FPs; n = 157,137 patients). The questionnaire and video recordings were used to determine the average frequency and time spent on cardiovascular primary preventive activities per FP respectively. Taking into account the annual income and full time equivalents of general practitioners, health care assistants, and practice nurses as well as the practice costs, the total spending on cardiovascular primary preventive activities in Dutch FPs was calculated. The database of Netherlands Information Network of General Practice was used to determine the prescribing behaviour in Dutch FPs by conducting multilevel regression models and adjusting for patient and practice characteristics. Total expenditure on cardiovascular primary preventive activities in FPs in 2009 was €38.8 million (€2.35 per capita), of which 47% was spent on blood pressure measurements, 26% on cardiovascular risk profiling, and 11% on lifestyle counselling. Fifteen percent (€11 per capita) of all cardiovascular medication prescribed in FPs was a PPCM. FPs differed greatly on prescription of PPCM (odds ratio of 3.1). Total costs of cardiovascular primary preventive activities in FPs such as blood pressure measurements and lifestyle counselling are relatively low compared to the costs of PPCM. There is considerable heterogeneity in prescribing behaviour of PPCM between FPs. Further research is needed to determine whether such large differences in

Full Text Available Abstract Background More optimistic perceptions of cardiovascular disease risk are associated with substantively lower rates of cardiovascular death among men. It remains unknown whether this association represents causality (i.e. perception leads to actions/conditions that influence cardiovascular disease occurrence or residual confounding by unmeasured factors that associate with risk perceptions and with physiological processes that promote cardiovascular disease (i.e. inflammation or endothelial dysfunction. Purpose To evaluate whether previously unmeasured biological markers of inflammation or endothelial dysregulation confound the observed association between cardiovascular disease risk perceptions and cardiovascular disease outcomes; Methods We conducted a nested case-cohort study among community-dwelling men from Southeastern New England (USA who were interviewed between 1989 and 1990 as part of the Pawtucket Heart Health Program. We measured C-reactive protein (CRP and Vascular Endothelial Growth Factor (VEGF levels from stored sera for a random sample of the parent cohort (control sample, n = 127 and all cases of cardiovascular death observed through 2005 (case sample, n = 44. We evaluated potential confounding using stratified analyses and logistic regression modeling. Results Optimistic ratings of risk associated with lower odds of dying from cardiovascular causes among men (OR = 0.39, 95% CI = 0.17, 0.91. Neither CRP nor VEGF confounded these findings. Conclusions The strong cardio-protective association between optimistic ratings of cardiovascular disease risk and lower rates of cardiovascular mortality among men is not confounded by baseline biomarkers of systemic inflammation or endothelial dysfunction.

High-quality ambulatory care can reduce cardiovascular disease risk, but important gaps exist in the provision of cardiovascular preventive care. We sought to develop a set of key performance indicators that can be used to measure and improve cardiovascular care in the primary care setting. As part of the Cardiovascular Health in Ambulatory Care Research Team initiative, we established a 14-member multidisciplinary expert panel to develop a set of indicators for measuring primary prevention performance in ambulatory cardiovascular care. We used a 2-stage modified Delphi panel process to rate potential indicators, which were identified from the literature and national cardiovascular organizations. The top-rated indicators were pilot tested to determine their measurement feasibility with the use of data routinely collected in the Canadian health care system. A set of 28 indicators of primary prevention performance were identified, which were grouped into 5 domains: risk factor prevalence, screening, management, intermediate outcomes and long-term outcomes. The indicators reflect the major cardiovascular risk factors including smoking, obesity, hypertension, diabetes, dyslipidemia and atrial fibrillation. All indicators were determined to be amenable to measurement with the use of population-based administrative (physician claims, hospital admission, laboratory, medication), survey or electronic medical record databases. The Cardiovascular Health in Ambulatory Care Research Team indicators of primary prevention performance provide a framework for the measurement of cardiovascular primary prevention efforts in Canada. The indicators may be used by clinicians, researchers and policy-makers interested in measuring and improving the prevention of cardiovascular disease in ambulatory care settings.

Tobacco use leads to increased mortality, the majority of which is attributed to cardiovascular disease. Despite this knowledge, the early cardiovascular impact of tobacco product use is not well understood. Tobacco use increases exposure to harmful and potentially harmful constituents including volatile organic compounds (VOCs) such as acrolein and crotonaldehyde, which may contribute to cardiovascular risk. The link between exposure patterns, risk profiles and demographic distribution of tobacco product users, particularly users of new and emerging products, are not well known. Therefore, we designed the Cardiovascular Injury due to Tobacco Use (CITU) study to assess population characteristics, demographic features, exposure patterns and cardiovascular risk in relation to tobacco. We present the design and methodology of the CITU study, a cross-sectional observational tobacco study conducted in Boston, Massachusetts and Louisville, Kentucky starting in 2014. Healthy participants 21-45 years of age who use tobacco products, including electronic nicotine devices, or who never used tobacco are being recruited. The study aims to recruit an evenly split cohort of African-Americans and Caucasians, that is, sex balanced for evaluation of self-reported tobacco exposure, VOC exposure and tobacco-induced injury profiling. Detailed information about participant's demographics, health status and lifestyle is also collected. The study protocol was approved institutional review boards at both participating universities. All study protocols will protect participant confidentiality. Results from the study will be disseminated via peer-reviewed journals and presented at scientific conferences. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

The British Regional Heart Study (BRHS) reported in 1986 that much of the inverse relation of high-density lipoprotein cholesterol (HDLC) and incidence of coronary heart disease was eliminated by covariance adjustment. Using the proportional hazards model and adjusting for age, blood pressure, smoking, body mass index, and low-density lipoprotein cholesterol, we analyzed this relation separately in the Framingham Heart Study (FHS), Lipid Research Clinics Prevalence Mortality Follow-up Study (LRCF) and Coronary Primary Prevention Trial (CPPT), and Multiple Risk Factor Intervention Trial (MRFIT). In CPPT and MRFIT (both randomized trials in middle-age high-risk men), only the control groups were analyzed. A 1-mg/dl (0.026 mM) increment in HDLC was associated with a significant coronary heart disease risk decrement of 2% in men (FHS, CPPT, and MRFIT) and 3% in women (FHS). In LRCF, where only fatal outcomes were documented, a 1-mg/dl increment in HDLC was associated with significant 3.7% (men) and 4.7% (women) decrements in cardiovascular disease mortality rates. The 95% confidence intervals for these decrements in coronary heart and cardiovascular disease risk in the four studies overlapped considerably, and all contained the range 1.9-2.9%. HDLC levels were essentially unrelated to non-cardiovascular disease mortality. When differences in analytic methodology were eliminated, a consistent inverse relation of HDLC levels and coronary heart disease event rates was apparent in BRHS as well as in the four American studies.

Riley, Callum James, and Matthew Gavin. Physiological changes to the cardiovascular system at high altitude and its effects on cardiovascular disease. High Alt Med Biol. 18:102-113, 2017.-The physiological changes to the cardiovascular system in response to the high altitude environment are well understood. More recently, we have begun to understand how these changes may affect and cause detriment to cardiovascular disease. In addition to this, the increasing availability of altitude simulation has dramatically improved our understanding of the physiology of high altitude. This has allowed further study on the effect of altitude in those with cardiovascular disease in a safe and controlled environment as well as in healthy individuals. Using a thorough PubMed search, this review aims to integrate recent advances in cardiovascular physiology at altitude with previous understanding, as well as its potential implications on cardiovascular disease. Altogether, it was found that the changes at altitude to cardiovascular physiology are profound enough to have a noteworthy effect on many forms of cardiovascular disease. While often asymptomatic, there is some risk in high altitude exposure for individuals with certain cardiovascular diseases. Although controlled research in patients with cardiovascular disease was largely lacking, meaning firm conclusions cannot be drawn, these risks should be a consideration to both the individual and their physician.

To examine cardiovascular disease risk factors and risk clusters in Swedish persons with traumatic wheelchair-dependent paraplegia. Prospective examination. A total of 135 individuals aged 18-79 years with chronic (>or= 1 year) post-traumatic paraplegia. Cardiovascular disease risk factors; dyslipidemia, impaired fasting glucose, hypertension, overweight, smoking, and medication usage for dyslipidemia, hypertension, and diabetes mellitus, were analyzed according to authoritative guidelines. Stepwise regression tested the effects of age, gender, and injury characteristics on cardiovascular disease risks. High-prevalence risk factors were dyslipidemia (83.1%), hypertension (39.3%), and overweight (42.2%) with pervasive clustering of these risks. Being older was related to increased cardiovascular disease risk, except for dyslipidemia. Hypertension was more common in low-level paraplegia. Prevalence of impaired fasting glucose was lower than previously reported after paraplegia. A high percentage of persons being prescribed drug treatment for dyslipidemia and hypertension failed to reach authoritative targets for cardiovascular disease risk reduction. Swedish persons with paraplegia are at high risk for dyslipidemia, hypertension, and overweight. Impaired fasting glucose was not as common as reported in some previous studies. Pharmacotherapy for dyslipidemia and hypertension often failed to achieve recommended targets. Population-based screening and therapeutic countermeasures to these cardiovascular disease risks are indicated.

This study investigated the relationship between weekly working hours and the occurrence of cerebro-cardiovascular diseases using a case-crossover study design. We investigated average working hours during the 7 days before the onset of illness (hazard period) and average weekly working hours between 8 days and 3 months before the onset of cerebro-cardiovascular diseases (control period) for 1,042 cases from the workers' compensation database for 2009. Among all subjects, the odds ratio by conditional logistic regression for the risk of cerebro-cardiovascular diseases with a 10 hr increase in average weekly working hours was 1.45 (95% confidence interval [CI]: 1.22-1.72), a significant association. An increase in average weekly working hours may trigger the onset of cerebro-cardiovascular disease. Am. J. Ind. Med. 60:753-761, 2017. © 2017. Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

Despite adequate glycemic and blood pressure control, treated type 2 diabetic hypertensive subjects have a significantly elevated overall/cardiovascular risk. We studied 244 816 normotensive and 99 720 hypertensive subjects (including 7480 type 2 diabetics) attending medical checkups between 1992 and 2011. We sought to identify significant differences in overall/cardiovascular risk between hypertension with and without diabetes mellitus. Mean follow-up was 12.7 years; 14 050 all-cause deaths were reported. From normotensive to hypertensive populations, a significant progression in overall/cardiovascular mortality was observed. Mortality was significantly greater among diabetic than nondiabetic hypertensive subjects (all-cause mortality, 14.05% versus 7.43%; and cardiovascular mortality, 1.28% versus 0.7%). No interaction was observed between hemodynamic measurements and overall/cardiovascular risk, suggesting that blood pressure factors, even during drug therapy, could not explain the differences in mortality rates between diabetic and nondiabetic hypertensive patients. Using cross-sectional regression models, a significant association was observed between higher education levels, lower levels of anxiety and depression, and reduced overall mortality in diabetic hypertensive subjects, while impaired renal function, a history of stroke and myocardial infarction, and increased alcohol and tobacco consumption were significantly associated with increased mortality. Blood pressure and glycemic control alone cannot reverse overall/cardiovascular risk in diabetics with hypertension. Together with cardiovascular measures, overall prevention should include recommendations to reduce alcohol and tobacco consumption and improve stress, education levels, and physical activity. © 2017 American Heart Association, Inc.

To improve the accuracy in risk prediction requires the assessment and treatment of different cardiovascular risk factors, which have a synergistic effect more than additive on the total cardiovascular risk. The calculus using quantitative methods is more accurate than that obtained with qualitative methods. The prediction of cardiovascular risk has been in past years the cornerstone in clinical guidances of cardiovascular prevention and becomes an useful tool for Family Physician to establish priorities in the primary care, improving the patients care and selecting in a more effective way the therapy to be followed to bring closer more to multifactor reality of cardiovascular diseases and its prevention.

This is an update of the original review published in 2008. The risk of adverse cardiovascular outcomes is increased with influenza-like infection, and vaccination against influenza may improve cardiovascular outcomes. To assess the potential benefits of influenza vaccination for primary and secondary prevention of cardiovascular disease. We searched the following electronic databases on 18 October 2013: The Cochrane Library (including Cochrane Central Register of Controlled Trials (CENTRAL), Database of Abstracts of Reviews of Effects (DARE), Economic Evaluation Database (EED) and Health Technology Assessment database (HTA)), MEDLINE, EMBASE, Science Citation Index Expanded, Conference Proceedings Citation Index - Science and ongoing trials registers (www.controlled-trials.com/ and www.clinicaltrials.gov). We examined reference lists of relevant primary studies and systematic reviews. We performed a limited PubMed search on 20 February 2015, just before publication. Randomised controlled trials (RCTs) of influenza vaccination compared with placebo or no treatment in participants with or without cardiovascular disease, assessing cardiovascular death or non-fatal cardiovascular events. We used standard methodological procedures as expected by The Cochrane Collaboration. We carried out meta-analyses only for cardiovascular death, as other outcomes were reported too infrequently. We expressed effect sizes as risk ratios (RRs), and we used random-effects models. We included eight trials of influenza vaccination compared with placebo or no vaccination, with 12,029 participants receiving at least one vaccination or control treatment. We included six new studies (n = 11,251), in addition to the two included in the previous version of the review. Four of these trials (n = 10,347) focused on prevention of influenza in the general or elderly population and reported cardiovascular outcomes among their safety analyses; four trials (n = 1682) focused on prevention of

There has been a rising interest in interarm blood pressure difference (IAD), due to its relationship with peripheral arterial disease and its possible relationship with cardiovascular disease. This study aimed to characterize hypertensive patients with a significant IAD in relation to cardiovascular risk. A total of 3699 patients (mean age, 61 ± 11 years) were prospectively enrolled in the study. Blood pressure (BP) was measured simultaneously in both arms 3 times using an automated cuff-oscillometric device. IAD was defined as the absolute difference in averaged BPs between the left and right arm, and an IAD ≥ 10 mm Hg was considered to be significant. The Framingham risk score was used to calculate the 10-year cardiovascular risk. The mean systolic IAD (sIAD) was 4.3 ± 4.1 mm Hg, and 285 (7.7%) patients showed significant sIAD. Patients with significant sIAD showed larger body mass index (P < 0.001), greater systolic BP (P = 0.050), more coronary artery disease (relative risk = 1.356, P = 0.034), and more cerebrovascular disease (relative risk = 1.521, P = 0.072). The mean 10-year cardiovascular risk was 9.3 ± 7.7%. By multiple regression, sIAD was significantly but weakly correlated with the 10-year cardiovascular risk (β = 0.135, P = 0.008). Patients with significant sIAD showed a higher prevalence of coronary artery disease, as well as an increase in 10-year cardiovascular risk. Therefore, accurate measurements of sIAD may serve as a simple and cost-effective tool for predicting cardiovascular risk in clinical settings.

Smoking and bronchodilator treatment are both extensively studied as key elements in patients with chronic obstructive pulmonary disease. However, little is known about whether or not these elements interact in terms of developing cardiovascular diseases in patients with COPD. To explore to what extent the risk of developing ischemic cardiovascular disease in COPD patients is mediated by smoking status, use of bronchodilators and--specifically--their interaction. We performed an observational pilot study on a relatively healthy Dutch COPD cohort from a primary care diagnostic center database with full information on spirometry tests, smoking status, bronchodilator use and other prescribed medication. We defined first ischemic cardiovascular events as primary outcome, measured by first prescription of antiplatelet drugs and/or nitrates. Unadjusted analyses by Kaplan-Meier were followed by adjusted Cox' proportional hazards. 845 COPD patients, totaling 2,169 observation years, were included in the analyses. We observed an increased risk for nonfatal ischemic cardiovascular events by smoking (adjusted HR=3.58, p=0.001) and a protective effect of bronchodilators (adjusted HR=0.43, p=0.01). Although the protective effect of bronchodilators appears to be substantially minimized in patients that persist in smoking, we could not statistically confirm a hazardous interaction between bronchodilators and smoking (HR 2.50, p=0.21). Our study reveals bronchodilators may protect from ischemic cardiovascular events in a relatively 'healthy' COPD population. We did not confirm a hazardous interaction between bronchodilators and smoking, although we observed current smokers benefit substantially less from the protective effect of bronchodilators.

In order to study if tricyclic antidepressant drugs (TCA) in therapeutic doses increase the risk of death due to cardiovascular causes, the relative mortality from cardiovascular diseases was studied in two large groups of first hospitalized manic-depressive patients, one from the TCA era...... to the general population. Among 1133 such cases admitted between 1950 and 1956, the rate was 1.87. Our findings do not support the hypothesis that TCA contribute to the cardiovascular mortality in manic-depressives and even support suggestions that TCA treatment may lower the risk of death by cardiovascular...

Substantial evidence suggests that consuming 1-2 servings of fish per week, particularly oily fish (e.g., salmon, herring, sardines) is beneficial for cardiovascular health due to its high n-3 polyunsaturated fatty acid content. However, there is some concern that the mercury content in fish may increase cardiovascular disease risk, but this relationship remains unclear. The PREDIMED trial included 7477 participants who were at high risk for cardiovascular disease at baseline. In this study, we evaluated associations between mercury exposure, fish consumption and cardiovascular disease. We randomly selected 147 of the 288 cases diagnosed with cardiovascular disease during follow-up and matched them on age and sex to 267 controls. Instrumental neutron activation analysis was used to assess toenail mercury concentration. In-person interviews, medical record reviews and validated questionnaires were used to assess fish consumption and other covariates. Information was collected at baseline and updated yearly during follow-up. We used conditional logistic regression to evaluate associations in the total nested case-control study, and unconditional logistic regression for population subsets. Mean (±SD) toenail mercury concentrations (μg per gram) did not significantly differ between cases (0.63 (±0.53)) and controls (0.67 (±0.49)). Mercury concentration was not associated with cardiovascular disease in any analysis, and neither was fish consumption or n-3 fatty acids. The fully-adjusted relative risks for the highest versus lowest quartile of mercury concentration were 0.71 (95% Confidence Interval [CI], 0.34, 1.14; p trend  = 0.37) for the nested case-control study, 0.74 (95% CI, 0.32, 1.76; p trend  = 0.43) within the Mediterranean diet intervention group, and 0.50 (95% CI, 0.13, 1.96; p trend  = 0.41) within the control arm of the trial. Associations remained null when mercury was jointly assessed with fish consumption at baseline and during follow

Pharmacogenomics in cardiovascular disorders: Steps in approaching personalized medicine in cardiovascular medicine

Full Text Available Christopher Barone, Shaymaa S Mousa, Shaker A MousaThe Pharmaceutical Research Institute, Albany College of Pharmacy and Health Sciences, Albany, NY, USAAbstract: Some of the most commonly prescribed medications are those for cardiovascular maladies. The beneficial effects of these medications have been well documented. However, there can be substantial variation in response to these medications among patients, which may be due to genetic variation. For this reason pharmacogenomic studies are emerging across all aspects of cardiovascular medicine. The goal of pharmacogenomics is to tailor treatment to an individual’s genetic makeup in order to improve the benefit-to-risk ratio. This review examines the potential pharmacogenomic parameters which may lead to a future of personalized medicine. For example, it has been found that patients with CYP2C9 and VKORC1 gene variations have a different response to warfarin. Other studies looking at β-blockers, ACE inhibitors, ARBs, diuretics and statins have shown some results linking genetic variations to pharmacologic response. However these studies have not impacted clinical use yet, unlike warfarin findings, as the small retrospective studies need to be followed up by larger prospective studies for definitive results.Keywords: cardiovascular, pharmacogenomics, genetics, cardiovascular medicine, personalized medicine, polymorphism

10-Year cardiovascular event risks for women who experienced hypertensive disorders in late pregnancy: the HyRAS study

Directory of Open Access Journals (Sweden)

Ponjee Gabrielle

2010-06-01

Full Text Available Abstract Background Cardiovascular disease is the cause of death in 32% of women in the Netherlands. Prediction of an individual's risk for cardiovascular disease is difficult, in particular in younger women due to low sensitive and specific tests for these women. 10% to 15% of all pregnancies are complicated by hypertensive disorders, the vast majority of which develop only after 36 weeks of gestation. Preeclampsia and cardiovascular disease in later life show both features of "the metabolic syndrome" and atherosclerosis. Hypertensive disorders in pregnancy and cardiovascular disease may develop by common pathophysiologic pathways initiated by similar vascular risk factors. Vascular damage occurring during preeclampsia or gestational hypertension may contribute to the development of future cardiovascular disease, or is already present before pregnancy. At present clinicians do not systematically aim at the possible cardiovascular consequences in later life after a hypertensive pregnancy disorder at term. However, screening for risk factors after preeclampsia or gestational hypertension at term may give insight into an individual's cardiovascular risk profile. Methods/Design Women with a history of preeclampsia or gestational hypertension will be invited to participate in a cohort study 2 1/2 years after delivery. Participants will be screened for established modifiable cardiovascular risk indicators. The primary outcome is the 10-year cardiovascular event risk. Secondary outcomes include differences in cardiovascular parameters, SNP's in glucose metabolism, and neonatal outcome. Discussion This study will provide evidence on the potential health gains of a modifiable cardiovascular risk factor screening program for women whose pregnancy was complicated by hypertension or preeclampsia. The calculation of individual 10-year cardiovascular event risks will allow identification of those women who will benefit from primary prevention by tailored

Full Text Available BACKGROUND: A pacemaker implantation is considered major life event for cardiovascular patients, so they will probably have very interesting experiences of living with this device. The aim of this study was to explore the experiences of cardiovascular patients living with the pacemaker. METHODS: In this qualitative study, 27 patients were chosen through purposive sampling to achieve data saturation, and their experiences were examined using semi-structured interviews. The patients’ statements were recorded with their consent and analyzed using content analysis method. RESULTS: Participants’ experiences included three main themes: “Problems and limitations,” “feeling and dealing with pacemaker”, and “sources of comfort” and 10 sub-themes including: physical problems, financial problems, social problems, the first encounter, the feeling of living with the pacemaker, how to cope with pacemaker, satisfaction with pacemaker, good family support, hospital and hospital staff performance, and role of religious beliefs. CONCLUSION: Planning to solve social problems, identifying and changing feelings of patients using pacemakers, reinforcing the resources of comfort especially family support seem to be necessary steps for improving quality of life and impact of using pacemaker.

There are scarce epidemiological data on cardiovascular risk profile of chronic hemodialysis patients in Brazil. The CORDIAL study was designed to evaluate cardiovascular risk factors and follow up a hemodialysis population in a Brazilian metropolitan city. All patients undergoing regular hemodialysis for chronic renal failure in all fifteen nephrology centers of Porto Alegre were considered for inclusion in the baseline phase of the CORDIAL study. Clinical, laboratory and demographic data were obtained in medical records and in structured individual interviews performed in all patients by trained researchers. A total of 1215 patients were included (97.3% of all hemodialysis patients in the city of Porto Alegre). Their average age was 58.3 years old, 59.5% were male and 62.8% were white. The prevalence of cardiovascular risk factors observed was 87.5% for hypertension, 84.7% for dyslipidemia, 73.1% for sedentary lifestyle, 53.7% for tobacco use, and 35.8% for diabetes. In a multivariate adjusted analysis, we found that sedentary lifestyle (p = 0.032, PR 1.08 - 95%CI: 1.01-1.15), dyslipidemia (p = 0.019, PR 1.08 - 95%CI: 1.01-1.14), and obesity (p < 0.001, PR 1.96 - 95%CI: 1.45-2.63) were more frequent in women; and hypertension (p = 0.018, PR 1.06 - 95%CI: 1.01-1.11) and tobacco use (p = 0.006, PR 2.7 - 95%CI: 1.79-4.17) were more often found among patients under 65 years old. Sedentary lifestyle was independently associated with time in dialysis less than 12 months (p < 0.001, PR 1.23 - 95% CI: 1.14-1.33). Hemodialysis patients in this southern metropolitan Brazilian city have a high prevalence of cardiovascular risk factors resembling many northern countries

Studies on the impact of single nutrients on the risk of CVD have often given inconclusive results. Recent research on dietary patterns has offered promising information on the effects of diet as a whole on the risk of CVD. The Cardiovascular Risk in Young Finns Study is an ongoing, prospective cohort study with a 21-year follow-up to date. The subjects were children and adolescents at baseline (3-18 years, n 1768) and adults at the latest follow-up study (24-39 years, n 1037). We investigated the associations between two major dietary patterns and several risk factors for CVD. In longitudinal analyses with repeated measurements, using multivariate mixed linear regression models, the traditional dietary pattern (characterised by high consumption of rye, potatoes, butter, sausages, milk and coffee) was independently associated with total and LDL cholesterol concentrations, apolipoprotein B and C-reactive protein concentrations among both genders, and also with systolic blood pressure and insulin levels among women and concentrations of homocysteine among men (P health-conscious food choices (such as high consumption of vegetables, legumes and nuts, tea, rye, cheese and other dairy products, and alcoholic beverages) was inversely, but less strongly associated with cardiovascular risk factors. Our results support earlier findings that dietary patterns have a role in the development of CVD.

Full Text Available ABSTRACTBACKGROUND: This is an update of the original review published in 2008. The risk of adverse cardiovascular outcomes is increased with influenza-like infection, and vaccination against influenza may improve cardiovascular outcomes.OBJECTIVES: To assess the potential benefits of influenza vaccination for primary and secondary prevention of cardiovascular disease.METHODS:Search methods:We searched the following electronic databases on 18 October 2013: The Cochrane Library (including Cochrane Central Register of Controlled Trials (CENTRAL, Database of Abstracts of Reviews of Effects (DARE, Economic Evaluation Database (EED and Health Technology Assessment database (HTA, MEDLINE, EMBASE, Science Citation Index Expanded, Conference Proceedings Citation Index - Science and ongoing trials registers (www.controlled-trials.com/ and www.clinicaltrials.gov. We examined reference lists of relevant primary studies and systematic reviews. We performed a limited PubMed search on 20 February 2015, just before publication.Selection criteria:Randomised controlled trials (RCTs of influenza vaccination compared with placebo or no treatment in participants with or without cardiovascular disease, assessing cardiovascular death or non-fatal cardiovascular events.Data collection and analysis:We used standard methodological procedures as expected by The Cochrane Collaboration. We carried out meta-analyses only for cardiovascular death, as other outcomes were reported too infrequently. We expressed effect sizes as risk ratios (RRs, and we used random-effects models.MAIN RESULTS: We included eight trials of influenza vaccination compared with placebo or no vaccination, with 12,029 participants receiving at least one vaccination or control treatment. We included six new studies (n = 11,251, in addition to the two included in the previous version of the review. Four of these trials (n = 10,347 focused on prevention of influenza in the general or elderly population

Adipokines as Possible New Predictors of Cardiovascular Diseases: A Case Control Study

Laura Pala

2012-01-01

Full Text Available Background and Aims. The secretion of several adipocytokines, such as adiponectin, retinol-binding protein 4 (RBP4, adipocyte fatty acid binding protein (aFABP, and visfatin, is altered in subjects with abdominal adiposity; these endocrine alterations could contribute to increased cardiovascular risk. The aim of the study was to assess the relationship among adiponectin, RBP4, aFABP, and visfatin, and incident cardiovascular disease. Methods and Results. A case-control study, nested within a prospective cohort, on 2945 subjects enrolled for a diabetes screening program was performed. We studied 18 patients with incident fatal or nonfatal IHD (Ischemic Heart Disease or CVD (Cerebrovascular Disease, compared with 18 matched control subjects. Circulating adiponectin levels were significantly lower in cases of IHD with respect to controls. Circulating RBP4 levels were significantly increased in CVD and decreased in IHD with respect to controls. Circulating aFABP4 levels were significantly increased in CVD, while no difference was associated with IHD. Circulating visfatin levels were significantly lower in cases of both CVD and IHD with respect to controls, while no difference was associated with CVD. Conclusions. The present study confirms that low adiponectin is associated with increased incidents of IHD, but not CVD, and suggests, for the first time, a major effect of visfatin, aFABP, and RBP4 in the development of cardiovascular disease.

Background Psoriasis has been associated with co-morbidities and elevated cardiovascular risk. Objectives To analyze the relationships among metabolic syndrome, cardiovascular risk, C-reactive protein, gender, and Psoriasis severity. Methods In this cross-sectional study, plaque Psoriasis patients (n=90), distributed equally in gender, were analyzed according to: Psoriasis Area and Severity Index, cardiovascular risk determined by the Framingham risk score and global risk assessment, C-reactive protein and metabolic syndrome criteria (NCEPT-ATP III). Results Metabolic syndrome frequency was 43.3% overall, without significance between genders (P=0.14); but women had higher risk for obesity (OR 2.56, 95%CI 1.02-6.41; P=0.04) and systemic arterial hypertension (OR 3.29, 95%CI 1.39-7.81; P=0.006). The increase in the Psoriasis Area and Severity Index also increased the risk for metabolic syndrome (OR 1.060, 95%CI 1.006-1.117; P=0.03). Absolute 10-year cardiovascular risk was higher in males (P=0.002), but after global risk assessment, 51.1% patients, 52.2% women, were re-classified as high-intermediate cardiovascular risk; without significance between genders (P=0.83). C-reactive protein level was elevated nearly six-fold overall, higher in metabolic syndrome (P=0.05), systemic arterial hypertension (P=0.004), and high-intermediate 10-year cardiovascular risk patients (Preactive protein patients (t=1.98; P=0.05). Study limitations Restricted sample, hospital-based and representative of a single center and no specification of psoriatic arthritis. Conclusions Psoriasis, metabolic syndrome, systemic arterial hypertension and age share the increase in C-reactive protein, which could implicate in additional burden for increasing the cardiovascular risk and be an alert for effective interventions.

Cardiovascular diseases are the leading cause of death in industrialized countries. Their incidence increases, apparently, as a, function of technological progress so that in the future they may become a major public health problem in developing countries too. Early diagnosis and prevention are the tools best suited to curb such an alarming trend, but our knowledge of these topics is unsatisfactory, Valuable information would be obtained through a systematic investigation of trace elements in relation to cardiovascular function and to various types of cardiovascular diseases. Such studies would provide clues to the following questions: 1. Why does the incidence and type of cardiovascular disease differ from one country to another? May this be related to differences in tissue mineral concentrations among various population groups? 2. Which trace elements if any are beneficial to cardiovascular health, and which are harmful ones that may act as aetiological agents for some cardiovascular diseases? 3. Is it possible to utilize measurements of mineral element concentration for diagnostic purposes in cardiovascular disease? (author)

Full Text Available ABSTRACT Objectives To determine the feasibility of assessing population cardiovascular risk with advanced hemodynamics in the Healthy Life in Suriname (HELISUR study. Methods This was a preliminary study conducted in May – June 2012 using the Technical-Economic-Legal-Operational-Scheduling (TELOS method to assess the feasibility of the HELISUR—a large-scale, cross-sectional population study of cardiovascular risk factors and disease in Suriname. Suriname, a middle-income country in South America with a population of mostly African and Asian ethnicity, has a high risk of cardiovascular disease. A total of 135 volunteers 18 – 70 years of age participated. A health questionnaire was tested in a primary health care center, and non-invasive cardiovascular evaluations were performed in an academic health center. The cardiovascular evaluation included sitting, supine, and standing blood pressure, and intermediate endpoints, such as cardiac output, peripheral vascular resistance, pulse wave velocity, and augmentation index. Results The TELOS testing found that communicating by cellular phone was most effective for appointment adherence, and that completion of the questionnaire often required assistance from a trained interviewer; modifications to improve the clarity of the questions are recommended. Regarding the extended cardiovascular assessments of peripheral and central hemodynamics, the findings showed these to be technically and operationally feasible and well tolerated by participants, in terms of burden and duration. Conclusions Findings of this feasibility assessment indicate that large-scale, detailed evaluations of cardiovascular risk, including a questionnaire and advanced central and peripheral hemodynamics, are feasible in a high-risk population in a middle-income setting.

The risk of cardiovascular events and death in patients with abdominal aortic aneurysms (AAA) is high. Screening has been introduced to reduce AAA related mortality; however, after AAA diagnosis, cardiovascular modification may be as important to patient outcomes as surveillance. The aim of this study was to assess cardiovascular risk reduction in patients with small AAA. Institutional approval was granted for The Vascular and Endovascular Research Network (VERN) to retrospectively collect data pertaining to cardiovascular risk reduction from four tertiary vascular units in England. Patients with small AAA (January 2013-December 2015) were included. Demographic details, postcode, current medications, and smoking status were recorded using a bespoke electronic database and analysed. In a secondary analysis VERN contacted all AAA screening units in England and Wales to assess their current protocols relating to CV protection. In total, 1053 patients were included (mean age 74 ± 9 years, all men). Of these, 745 patients (70.8%) had been prescribed an antiplatelet agent and 787 (74.7%) a statin. Overall, only 666 patients (63.2%) were prescribed both a statin and antiplatelet. Two hundred and sixty eight patients (32.1%) were current smokers and the proportion of patients who continued to smoke decreased with age. Overall, only 401 patients (48.1%) were prescribed a statin, antiplatelet, and had stopped smoking. In the secondary analysis 38 AAA screening units (84% national coverage) replied. Thirty-one units (82%) suggest changes to the patient's prescription; however, none monitor compliance with these recommendations or assess whether the general practitioner has been made aware of the AAA diagnosis or prescription advice. Many patients with small AAA are not prescribed an antiplatelet/statin, and still smoke cigarettes, and therefore remain at high risk of cardiovascular morbidity and mortality. National guidance to ensure this high risk group of patients is

Methods: The concentrations of serum neuropeptides (β-EP, NT, NPY) were measured on the 1 st, 3 rd, 7 th, 14 th day after the onset of disease with RIA in 103 patients with acute cardiovascular and cerebrovascular diseases (38 cases of acute cerebral infarction, 32 cases of cerebral hemorrhage, 33 cases of acute myocardial infarction and acute heart failure) and 66 controls. Results: 1. NPY, NT and β-EP levels in patients with acute cardiovascular and cerebrovascular disease were significantly higher than those in controls (p<0.01). (F=39.54, p<0.01; F=33.38, p<0.01; F=8.38, p<0.01 For β-EP, NPY and NT respectively). 2. The plasma neuropeptide levels were highest at onset and gradually lowered till to normal levels on the 14 th day. Conclusion: Plasma neuropeptide levels were closely related to the pathogenesis and clinical outcome of acute cardiovascular and cerebrovascular diseases, study of which might be useful in the clinical management of the diseases

To investigate whether there is an increased risk of cardiovascular events in people who exhibit iatrogenic Cushing's syndrome during treatment with glucocorticoids. Cohort study. 424 UK general practices contributing to The Health Improvement Network database. People prescribed systemic glucocorticoids and with a diagnosis of iatrogenic Cushing's syndrome (n = 547) and two comparison groups: those prescribed glucocorticoids and with no diagnosis of iatrogenic Cushing's syndrome (n = 3231) and those not prescribed systemic glucocorticoids (n = 3282). Incidence of cardiovascular events within a year after diagnosis of iatrogenic Cushing's syndrome or after a randomly selected date, and association between iatrogenic Cushing's syndrome and risk of cardiovascular events. 417 cardiovascular events occurred in 341 patients. Taking into account only the first event by patient (coronary heart disease n = 177, heart failure n = 101, ischaemic stroke n = 63), the incidence rates of cardiovascular events per 100 person years at risk were 15.1 (95% confidence interval 11.8 to 18.4) in those prescribed glucocorticoids and with a diagnosis of iatrogenic Cushing's syndrome, 6.4 (5.5 to 7.3) in those prescribed glucocorticoids without a diagnosis of iatrogenic Cushing's syndrome, and 4.1 (3.4 to 4.8) in those not prescribed glucocorticoids. In multivariate analyses adjusted for sex, age, intensity of glucocorticoid use, underlying disease, smoking status, and use of aspirin, diabetes drugs, antihypertensive drugs, lipid lowering drugs, or oral anticoagulant drugs, the relation between iatrogenic Cushing's syndrome and cardiovascular events was strong (adjusted hazard ratios 2.27 (95% confidence interval 1.48 to 3.47) for coronary heart disease, 3.77 (2.41 to 5.90) for heart failure, and 2.23 (0.96 to 5.17) for ischaemic cerebrovascular events). The adjusted hazard ratio for any cardiovascular event was 4.16 (2.98 to 5.82) when the group prescribed glucocorticoids and with

AIMS: Educational inequality in diseases in the circulatory system (here termed cardiovascular disease) is well documented but may be confounded by early life factors. The aim of this observational study was to examine whether the associations between education and all cardiovascular diseases...... educational status was associated with a higher risk of cardiovascular disease, ischaemic heart disease and stroke. All associations attenuated in the within-sibship analyses, in particular in the analyses on ischaemic heart disease before age 45 years. For instance, in the cohort analyses, the hazard rate...... factors shared by siblings explained the associations between education and the cardiovascular disease outcomes but to varying degrees. This should be taken into account when planning interventions aimed at reducing educational inequalities in the development of cardiovascular disease, ischaemic heart...

To assess the distribution of antihyperglycemic treatments according to age and renal function and its relationship with cardiovascular disease in type 2 diabetes mellitus (T2DM). Cross-sectional analysis. Nineteen hospital-based diabetes mellitus clinics in 2007 and 2008. Fifteen thousand seven hundred thirty-three individuals with T2DM from the Renal Insufficiency and Cardiovascular Events (RIACE) Italian Multicenter Study. Current antihyperglycemic treatments were recorded. Estimated glomerular filtration rate (eGFR) was calculated using the Chronic Kidney Disease Epidemiology Collaboration equation. Albuminuria was measured using immunonephelometry or immunoturbidimetry. Prevalence of major acute cardiovascular events was calculated according to age quartiles, treatments, and categories of eGFR (1 = ≥90; 2 = 60-89; 3 = 30-59; and 4 = metformin or glitazones fell; percentage taking sulphonylureas and repaglinide rose, and percentage taking insulin remained stable. In eGFR categories 3 and 4, use of metformin was 41.4% and 14.5%, respectively, and that of sulphonylureas was 34.2% and 18.1%, respectively. Inappropriate prescription of these agents, especially sulphonylureas, increased with age. Metformin was independently associated with lower prevalence of cardiovascular disease for any age quartile and eGFR category than all other treatments. In real-life conditions, use of agents that are not recommended in elderly adults with diabetes mellitus with moderate to severe renal impairment is frequent, but metformin is associated with lower cardiovascular event rates even in these individuals. © 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society.

Cardiovascular disease is the most common cause of morbidity and mortality globally. Epidemiological studies using high-sensitivity assays for serum C-reactive protein have shown a consistent association between cardiovascular disease risk and serum C-reactive protein concentrations. C-reactive protein is a biomarker for inflammation, and has been established in clinical practice as an independent risk factor for cardiovascular disease events. There is evidence that serum C-reactive protein is an excellent biomarker of cardiovascular disease and is also an independent and strong predictor of adverse cardiovascular events. Further characterization of the impact and influence of lifestyle exposures and genetic variation on the C-reactive protein response to cardiovascular disease events may have implications for the therapeutic approaches to reduce cardiovascular disease events. This review summarizes the studies that have examined the association between serum C-reactive protein and the risk of cardiovascular disease. We also discuss the impact of independent factors and C-reactive protein genetic polymorphisms on baseline plasma C-reactive protein levels. © 2018 Wiley Periodicals, Inc.

Cardiovascular effects of air pollution.

Bourdrel, Thomas; Bind, Marie-Abèle; Béjot, Yannick; Morel, Olivier; Argacha, Jean-François

2017-11-01

Air pollution is composed of particulate matter (PM) and gaseous pollutants, such as nitrogen dioxide and ozone. PM is classified according to size into coarse particles (PM 10 ), fine particles (PM 2.5 ) and ultrafine particles. We aim to provide an original review of the scientific evidence from epidemiological and experimental studies examining the cardiovascular effects of outdoor air pollution. Pooled epidemiological studies reported that a 10μg/m 3 increase in long-term exposure to PM 2.5 was associated with an 11% increase in cardiovascular mortality. Increased cardiovascular mortality was also related to long-term and short-term exposure to nitrogen dioxide. Exposure to air pollution and road traffic was associated with an increased risk of arteriosclerosis, as shown by premature aortic and coronary calcification. Short-term increases in air pollution were associated with an increased risk of myocardial infarction, stroke and acute heart failure. The risk was increased even when pollutant concentrations were below European standards. Reinforcing the evidence from epidemiological studies, numerous experimental studies demonstrated that air pollution promotes a systemic vascular oxidative stress reaction. Radical oxygen species induce endothelial dysfunction, monocyte activation and some proatherogenic changes in lipoproteins, which initiate plaque formation. Furthermore, air pollution favours thrombus formation, because of an increase in coagulation factors and platelet activation. Experimental studies also indicate that some pollutants have more harmful cardiovascular effects, such as combustion-derived PM 2.5 and ultrafine particles. Air pollution is a major contributor to cardiovascular diseases. Promotion of safer air quality appears to be a new challenge in cardiovascular disease prevention.

1976-01-01

Surface area of lands transformed by coal mining in the basin are analyzed. In 1975 there were 3,110.9 ha of waste lands. Of this, spoil banks dumped on the surface covered 1,019.5 ha, spoil banks located in the cuts of surface mines (e.g. where sand is removed for stowing) or in other subsided places covered 1,064.5 ha, and water reservoirs covered 665.6 ha. Composition of spoil banks produced by black coal mines is analyzed from the point of view of land reclamation. A scheme of reclamation of spoil banks used in the Upper Silesian black coal basin is given. Reclamation of 5 large spoil banks is described. The land reclamation procedure consists in: leveling the spoil bank slopes so that their inclination is 1:10 instead of 1:4. When afforestation is used relatively steep slopes (1:4) are not leveled, centers of endogenic fires are extinguished by packing using rollers, the top layer of a spoil bank is mixed with calcium carbonate (3 to 10 kg/ha), then the top layer of waste fertilized by calcium carbonate is covered with soil (in some cases with fertile soil), soil cover ranges from 15 to 30 cm, the top soil cover is fertilized (dose ranges from 300 to 500 kg/ha). Later lupine is planted and ploughed as additional fertilizer. At a later stage trees and bushes are planted. (10 refs.) (In Polish)

Full Text Available Since President Obama announced the Precision Medicine Initiative in the United States, more and more attention has been paid to precision medicine. However, clinicians have already used it to treat conditions such as cancer. Many cardiovascular diseases have a familial presentation, and genetic variants are associated with the prevention, diagnosis, and treatment of cardiovascular diseases, which are the basis for providing precise care to patients with cardiovascular diseases. Large-scale cohorts and multiomics are critical components of precision medicine. Here we summarize the application of precision medicine to cardiovascular diseases based on cohort and omic studies, and hope to elicit discussion about future health care.

The long-term consequences of extreme prematurity are becoming increasingly important, given recent improvements in neonatal intensive care. The aim of the current study was to examine the cardiovascular consequences of extreme prematurity in 11-year-olds born at or before 25 completed weeks of gestation. Age and sex-matched classmates were recruited as controls. Information concerning perinatal and maternal history was collected, and current anthropometric characteristics were measured in 219 children born extremely preterm and 153 classmates. A subset of the extremely preterm children (n = 68) and classmates (n = 90) then underwent detailed haemodynamic investigations, including measurement of supine blood pressure (BP), aortic pulse wave velocity (aPWV, a measure of aortic stiffness) and augmentation index (AIx, a measure of arterial pressure wave reflections). Seated brachial systolic and diastolic BP were not different between extremely preterm children and classmates (P = 0.3 for both), although there was a small, significant elevation in supine mean and diastolic BP in the extremely preterm children (P prematurity is associated with altered arterial haemodynamics in children, not evident from the examination of brachial BP alone. Moreover, the smaller, preresistance and resistance vessels rather than large elastic arteries appear to be most affected. Children born extremely preterm may be at increased future cardiovascular risk.

Full Text Available Previous studies have reported an association between a more pro-inflammatory diet profile and various chronic metabolic diseases. The Dietary Inflammatory Index (DII was used to assess the inflammatory potential of nutrients and foods in the context of a dietary pattern. We prospectively examined the association between the DII and the incidence of cardiovascular disease (CVD: myocardial infarction, stroke or cardiovascular death in the PREDIMED (Prevención con Dieta Mediterránea study including 7216 high-risk participants. The DII was computed based on a validated 137-item food frequency questionnaire. Multivariate-adjusted hazard ratios (HR and 95% confidence intervals of CVD risk were computed across  quartiles of the DII where the lowest (most anti-inflammatory quartile is the referent. Risk increased across the quartiles (i.e., with increasing inflammatory potential: HRquartile2 = 1.42 (95%CI = 0.97–2.09;  HRquartile3 = 1.85 (1.27–2.71; and HRquartile4 = 1.73 (1.15–2.60. When fit as continuous the multiple-adjusted hazard ratio for each additional standard deviation of the DII was 1.22 (1.06–1.40. Our results provide direct prospective evidence that a pro-inflammatory diet is associated with a higher risk of cardiovascular clinical events.

The cardiovascular safety of sibutramine is currently under review by medicines regulatory authorities worldwide after the SCOUT (Sibutramine Cardiovascular Outcome Trial) showed an increased risk of cardiovascular events in patients taking sibutramine. Further data regarding the cardiovascular safety of sibutramine in a general population are now required. To quantify the risk of fatal and non-fatal cardiovascular adverse events in a general population prescribed sibutramine in postmarketing use. Observational prospective cohort study of patients dispensed sibutramine during a 3-year period (2001-4) and followed up for at least 1 year after their last prescription. The study included record-linkage to national mortality datasets to identify fatal events. Postmarketing 'real-life' use of sibutramine in a general population in New Zealand. All New Zealand patients dispensed a prescription for sibutramine in a 3-year period (for whom a National Health Identification number could be validated). 15 686 patients were included in the record linkage study for fatal events. A subgroup of 9471 patients was followed up by intensive methods for non-fatal events. (i) Rate of death from all causes and from cardiovascular events; and (ii) rates of non-fatal cardiovascular adverse events. Total exposure to sibutramine for 15 686 patients in the validated cohort was 5431 treatment-years. The rate of death from all causes in this cohort was 0.13 (95% CI 0.05, 0.27) per 100 treatment-years exposure. The rate of death from a cardiovascular event was 0.07 (95% CI 0.02, 0.19) per 100 treatment-years exposure. The most frequent non-fatal cardiovascular events in the intensively followed up cohort were hypertension, palpitations, hypotensive events and tachycardia. Risk of death from a cardiovascular event in this general population of patients prescribed sibutramine was lower than has been reported in other overweight/obese populations. The results of this study suggest that further

The combined effects of preterm delivery, small-for-gestational-age offspring, hypertensive disorders of pregnancy, placental abruption and stillbirth on early maternal death from cardiovascular causes have not previously been described in a large cohort. We investigated the effects of pregnancy complications on early maternal death in a registry-based retrospective cohort study of 782 287 women with a first singleton delivery in Denmark 1978-2007, followed for a median of 14.8 years (range 0.25-30.2) accruing 11.6 million person-years. We employed Cox proportional hazard models of early death from cardiovascular and non-cardiovascular causes following preterm delivery, small-for-gestational-age offspring and hypertensive disorders of pregnancy. We found that preterm delivery and small-for-gestational-age were both associated with subsequent death of mothers from cardiovascular and non-cardiovascular causes. Severe pre-eclampsia was associated with death from cardiovascular causes only. There was a less than additive effect on cardiovascular mortality hazard ratios with increasing number of pregnancy complications: preterm delivery 1.90 [95% confidence intervals 1.49, 2.43]; preterm delivery and small-for-gestational-age offspring 3.30 [2.25, 4.84]; preterm delivery, small-for-gestational-age offspring and pre-eclampsia 3.85 [2.07, 7.19]. Thus, we conclude that, separately and combined, preterm delivery and small-for-gestational-age are strong markers of early maternal death from both cardiovascular and non-cardiovascular causes, while hypertensive disorders of pregnancy are markers of early death of mothers from cardiovascular causes.

There is abundant evidence that neighborhood characteristics are significantly linked to the health of the inhabitants of a given space within a given time frame. This study is to statistically validate a web-based GIS application designed to support cardiovascular-related research developed by the NIH funded Research Centers in Minority Institutions (RCMI) Translational Research Network (RTRN) Data Coordinating Center (DCC) and discuss its applicability to cardiovascular studies. Geo-referencing, geocoding and geospatial analyses were conducted for 500 randomly selected home addresses in a U.S. southeastern Metropolitan area. The correlation coefficient, factor analysis and Cronbach's alpha (α) were estimated to quantify measures of the internal consistency, reliability and construct/criterion/discriminant validity of the cardiovascular-related geospatial variables (walk score, number of hospitals, fast food restaurants, parks and sidewalks). Cronbach's α for CVD GEOSPATIAL variables was 95.5%, implying successful internal consistency. Walk scores were significantly correlated with number of hospitals (r = 0.715; p restaurants (r = 0.729; p application were internally consistent and demonstrated satisfactory validity. Therefore, the GIS application may be useful to apply to cardiovascular-related studies aimed to investigate potential impact of geospatial factors on diseases and/or the long-term effect of clinical trials.

Aim was to examine the relationship between individually perceived changes in psychosocial stressors associated with German reunification and cardiovascular effects. We hypothesised that higher levels of psychosocial stress related to German reunification were associated with an increase in cardiovascular risk factors and cardiovascular diseases (CVDs). Cross-sectional data from 2 cohort studies in East Germany were used: Cardiovascular Disease, Living and Ageing in Halle Study (CARLA), and Study of Health in Pomerania (SHIP). 2 populations in East Germany. CARLA study: 1779 participants, aged 45-83 years at baseline (812 women), SHIP study: 4308 participants, aged 20-79 years at baseline (2193 women). Psychosocial stressors related to reunification were operationalised by the Reunification Stress Index (RSI; scale from 0 to 10). This index was composed of questions that were related to individually perceived changes in psychosocial stressors (occupational, financial and personal) after reunification. To examine the associations between the RSI and each stressor separately with cardiovascular risk factors and CVD, regression models were used. RSI was associated with CVD in women (RR=1.15, 95% CI 1.00 to 1.33). Cardiovascular risk factors were associated with RSI for both men and women, with strongest associations between RSI and diabetes in women (RR=1.10, 95% CI 1.01 to 1.20) and depressive disorders in men (RR=1.15, 95% CI 1.07 to 2.77). The change in occupational situation related to reunification was the major contributing psychosocial stressor. We observed a strong association with CVD in women who experienced occupational deterioration after reunification (RR=4.04, 95% CI 1.21 to 13.43). Individually perceived deterioration of psychosocial stressors (occupational, financial and personal) related to German reunification was associated with cardiovascular risk factors and CVD. The associations were stronger for women than for men. An explanation for these

To assess in one time window cardiovascular risks for both patients with gout and patients with rheumatoid arthritis in a Dutch primary care population. Retrospective matched cohort study with data from the electronic health records of 51 Dutch general practices. Participants were patients aged 30 years or older with an incident diagnosis of gout (n=2655) or rheumatoid arthritis (n=513), and matched non-disease controls (n=7891 and n=1850 respectively). At disease incidence date, patients and controls were compared for prevalence of hypertension, diabetes mellitus, hypercholesterolemia, and prior cardiovascular diseases. Patients without prior cardiovascular disease were followed for a first cardiovascular disease, and compared to controls using Kaplan-Meier survival curves and Cox proportional hazard analyses. Compared to controls, gout patients suffered more from hypertension (44.8%), diabetes (20.1%), hypercholesterolemia (13.7%), and prior cardiovascular disease (30%) (P0.05). After adjustment, both gout and rheumatoid arthritis patients without prior cardiovascular disease were more likely to get a cardiovascular disease: hazard ratio (95% confidence interval) 1.44 (1.18 to 1.76), and 2.06 (1.34 to 3.16) respectively. This primary care study indicates that gout and rheumatoid arthritis are both independent risk factors for cardiovascular diseases, rheumatoid arthritis to some greater extent, whereas gout patients at first diagnosis had already an increased cardiovascular risk profile. It gives strong arguments for implementation of both rheumatic diseases in primary care guidelines on cardiovascular risk management. Copyright © 2016 Société française de rhumatologie.

Homocysteine status and cardiovascular risk factors in patients with psoriasis: a case-control study.

LENUS (Irish Health Repository)

Tobin, A-M

2012-02-01

BACKGROUND: Psoriasis is a hyperproliferative, cutaneous disorder with the potential to lower levels of folate. This may result in raised levels of homocysteine, an independent risk factor for the development of cardiovascular disease. OBJECTIVE: A study was conducted to compare levels of red-cell folate (RCF) and homocysteine in patients with psoriasis and in healthy controls. Levels of homocysteine were also examined in the context of other major cardiovascular risk factors. METHODS: In total, 20 patients with psoriasis and 20 controls had their RCF, homo-cysteine and other conventional cardiovascular risk factors assessed. RESULTS: Patients with psoriasis had a trend towards lower levels of RCF. Significantly raised levels of homocysteine were found in patients with psoriasis compared with controls (P = 0.007). There was no correlation between homocysteine levels, RCF levels or disease activity as measured by the Psoriasis Area and Severity Index. Patients with psoriasis had higher body mass index (P < 0.004) and higher systolic blood pressure (P < 0.001) than controls. This may contribute to the excess cardiovascular mortality observed in patients with psoriasis.

We examined the reliability of measures of fMRI, subjective, and cardiovascular reactions to standardized versions of a Stroop color-word task and a multisource interference task. A sample of 14 men and 12 women (30-49 years old) completed the tasks on two occasions, separated by a median of 88 days. The reliability of fMRI BOLD signal changes in brain areas engaged by the tasks was moderate, and aggregating fMRI BOLD signal changes across the tasks improved test-retest reliability metrics. These metrics included voxel-wise intraclass correlation coefficients (ICCs) and overlap ratio statistics. Task-aggregated ratings of subjective arousal, valence, and control, as well as cardiovascular reactions evoked by the tasks showed ICCs of 0.57 to 0.87 (ps reliability. These findings support using these tasks as a battery for fMRI studies of cardiovascular reactivity. Copyright © 2012 Society for Psychophysiological Research.

This study examined the prevalence of airline pilots who have an excessive cardiovascular disease (CVD) risk score according to the New Zealand Guideline Group (NZGG) Framingham-based Risk Chart and describes their cardiovascular risk assessment and investigations. A cross-sectional study was performed among 856 pilots employed in an Oceania based airline. Pilots with elevated CVD risk that had been previously evaluated at various times over the previous 19 yr were reviewed retrospectively from the airline's medical records, and the subsequent cardiovascular investigations were then described. There were 30 (3.5%) pilots who were found to have 5-yr CVD risk score of 10-15% or higher. Of the 29 pilots who had complete cardiac investigations data, 26 pilots underwent exercise electrocardiography (ECG), 2 pilots progressed directly to coronary angiograms and 1 pilot with abnormal echocardiogram was not examined further. Of the 26 pilots, 7 had positive or borderline exercise tests, all of whom subsequently had angiograms. One patient with a negative exercise test also had a coronary angiogram. Of the 9 patients who had coronary angiograms as a consequence of screening, 5 had significant disease that required treatment and 4 had either trivial disease or normal coronary arteries. The current approach to investigate excessive cardiovascular risk in pilots relies heavily on exercise electrocardiograms as a diagnostic test, and may not be optimal either to detect disease or to protect pilots from unnecessary invasive procedures. A more comprehensive and accurate cardiac investigation algorithm to assess excessive CVD risk in pilots is required.

Cardiovascular Risk in Primary Hyperaldosteronism.

2015-12-01

After the first cases of primary aldosteronism were described and characterized by Conn, a substantial body of experimental and clinical evidence about the long-term effects of excess aldosterone on the cardiovascular system was gathered over the last 5 decades. The prevalence of primary aldosteronism varies considerably between different studies among hypertensive patients, depending on patient selection, the used diagnostic methods, and the severity of hypertension. Prevalence rates vary from 4.6 to 16.6% in those studies in which confirmatory tests to diagnose primary aldosteronism were used. There is also growing evidence indicating that prolonged exposure to elevated aldosterone concentrations is associated with target organ damage in the heart, kidney, and arterial wall, and high cardiovascular risk in patients with primary aldosteronism. Therefore, the aim of treatment should not be confined to BP normalization and hypokalemia correction, but rather should focus on restoring the deleterious effects of excess aldosterone on the cardiovascular system. Current evidence convincingly demonstrates that both surgical and medical treatment strategies beneficially affect cardiovascular outcomes and mortality in the long term. Further studies can be expected to provide better insight into the relationship between cardiovascular risk and complications and the genetic background of primary aldosteronism. © Georg Thieme Verlag KG Stuttgart · New York.

To evaluate the level of cardiovascular risk in smokers seenin Primary Care clinics. Epidemiologic, cross-sectional and multicentre study. Primary Care. Every investigator included 4 consecutive patients (3 smokers, 1 non-smoker) aged 35-50 years, who came to the clinic for any reason. A total of 2,184 patients were included; 2,124 (1,597 smokers; 527 non-smokers) were evaluated and 60 patients were excluded because they did not meet with selection criteria. The 10-year risk of suffering from a fatal cardiovascular disease (CVDR) was calculated according to the SCORE (Systematic Coronary Risk Evaluation) model. The 10-year lethal CVR according SCORE model, was classified as: very high (> 15%), high (10-14%), slightly high (5-9%), average (3-4%), low (2%), very low (1%) and negligible (smokers (40±5.3) vs. non-smokers (1.9±2.5) (Pnon-smokers vs. 60.7% smokers (Pnon-smokers vs. 12.6% smokers (P 5%) [10.9% non-smokers vs. 26.7% smokers (Pnon-smokers vs. smokers had less probability of suffering myocardial infarction (OR 0.3; 95% confidence interval (95% CI): 0.1-0.8; P<.0001), peripheral vascular disease (OR 0.6; 95% CI: 0.4-1.0; P=.0180) and chronic obstructive lung disease (OR 0.18; 95% CI: 0.1-0.2; P=.0507). Smoking is related to a high risk of fatal cardiovascular disease. Active promotion in Primary Care clinics of measures aimed at reducing the prevalence of the smoking habit would lead to a lowering of cardiovascular morbidity and mortality.

To assess the association of pre-eclampsia with later cardiovascular death in mothers according to their lifetime number of pregnancies, and particularly after only one child. Prospective, population based cohort study. Medical Birth Registry of Norway. We followed 836,147 Norwegian women with a first singleton birth between 1967 and 2002 for cardiovascular mortality through linkage to the national Cause of Death Registry. About 23,000 women died by 2009, of whom 3891 died from cardiovascular causes. Associations between pre-eclampsia and cardiovascular death were assessed by hazard ratios, estimated by Cox regression analyses. Hazard ratios were adjusted for maternal education (three categories), maternal age at first birth, and year of first birth The rate of cardiovascular mortality among women with preterm pre-eclampsia was 9.2% after having only one child, falling to 1.1% for those with two or more children. With term pre-eclampsia, the rates were 2.8% and 1.1%, respectively. Women with pre-eclampsia in their first pregnancy had higher rates of cardiovascular death than those who did not have the condition at first birth (adjusted hazard ratio 1.6 (95% confidence interval 1.4 to 2.0) after term pre-eclampsia; 3.7 (2.7 to 4.8) after preterm pre-eclampsia). Among women with only one lifetime pregnancy, the increase in risk of cardiovascular death was higher than for those with two or more children (3.4 (2.6 to 4.6) after term pre-eclampsia; 9.4 (6.5 to 13.7) after preterm pre-eclampsia). The risk of cardiovascular death was only moderately elevated among women with pre-eclamptic first pregnancies who went on to have additional children (1.5 (1.2 to 2.0) after term pre-eclampsia; 2.4 (1.5 to 3.9) after preterm pre-eclampsia). There was little evidence of additional risk after recurrent pre-eclampsia. All cause mortality for women with two or more lifetime births, who had pre-eclampsia in first pregnancy, was not elevated, even with preterm pre-eclampsia in first

Environmental Factors and Cardiovascular Diseases

Full Text Available Epidemiological and clinical observations have led to the hypothesis that the risk of developing cardiovascular diseases is influenced not only by genetic, lifestyle and major risk factors, but also by environmental factors. Environmental factors are considered key determinants of cardiovascular diseases. Although lifestyle choices such as smoking, diet, and exercise are viewed as major environmental influences, the contribution of pollutants and environmental chemicals is less clear. Accumulating evidence suggests that exposure to physically and chemical pollutants could elevate the risk of cardiovascular diseases. Many epidemiological studies report that exposure to physically, biologically and socio-cultural environmental factors are associated with an increase in cardiovascular mortality. Relationships between environmental factors and coronary arter disease, arhythmias, and cardiomyopathies have been reported. Exposures to arsenic, lead, cadmium, pollutant gases, solvents, and pesticides have also been linked to increased incidence of cardiovascular disease. In this paper, I review that relationships between exposure to physically, chemical, biologically and socio-cultural environmental factors and cardiovascular diseases.

A multitude of studies have been published on the relationship between cardiovascular disease risk and a variety of nutrients, foods, and dietary patterns. Despite the well-accepted notion that diet has a significant influence on the development and prevention of cardiovascular disease, the foods considered healthy and harmful have varied over the years. This review aims to summarize the current scientific evidence on the cardioprotective effect of those foods and nutrients that have been considered healthy as well as those that have been deemed unhealthy at any given time in history. For this purpose, we reviewed the most recent literature using as keywords foods and nutrients (ie, meat, omega-3) and cardiovascular disease-related terms (ie, cardiovascular diseases, stroke). Emphasis has been placed on meta-analyses and Cochrane reviews. In general, there is a paucity of intervention studies with a high level of evidence supporting the benefits of healthy foods (ie, fruits and vegetables), whereas the evidence supporting the case against those foods considered less healthy (ie, saturated fat) seems to be weakened by most recent evidence. In summary, most of the evidence supporting the benefits and harms of specific foods and nutrients is based on observational epidemiological studies. The outcome of randomized clinical trials reveals a more confusing picture with most studies providing very small effects in one direction or another; the strongest evidence comes from dietary patterns. The current status of the relationship between diet and cardiovascular disease risk calls for more tailored recommendations based on genomic technologies.

The cardiovascular safety of sitagliptin has been evaluated in TECOS ("Trial Evaluating Cardiovascular Outcomes with Sitagliptin"). TECOS recruited patients with type 2 diabetes and a history of cardiovascular disease who received, as add-on to their usual therapy, either sitagliptin (n = 7.257) or placebo (n = 7.266), with a median follow-up of 3 years. The primary cardiovascular outcome was a composite of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for unstable angina. Sitagliptin was noninferior to placebo for the primary composite cardiovascular outcome (hazard ratio, 0.98; 95% confidence interval, 0.88 to 1.09; P<0.001). Rates of hospitalization for heart failure did not differ between the two groups (hazard ratio, 1.00; 95% CI, 0.83 to 1.20; P=0.98). The cardiovascular safety of sitagliptin, which was already shown in meta-analyses of phase II-III randomised controlled trials and in observational cohort studies in real life, is now confirmed in the landmark prospective cardiovascular outcome study TECOS.

Electrocardiographic QRS duration at rest is associated with sudden cardiac death and death from coronary heart disease in the general population. However, its relation to cardiovascular events in American Indians, a population with persistently high cardiovascular disease mortality, is unknown. The relation of QRS duration to incident cardiovascular disease during 17.2 years of follow-up was assessed in 1,851 male and female Strong Heart Study participants aged 45 to 74 years without known cardiovascular disease at baseline. Cox regression with robust standard error estimates was used to determine the association between quintiles of QRS duration and incident cardiovascular disease in gender-stratified analyses, adjusted for age, systolic blood pressure, hypertension, antihypertensive medication use, body mass index, current smoking, diabetes, total cholesterol, high-density lipoprotein cholesterol, and albuminuria. In women only, QRS duration in the highest quintile (≥105 ms) conferred significantly higher risk of cardiovascular disease than QRS duration in the lowest quintile (64 to 84 ms) (hazard ratio 1.6, 95% CI 1.1 to 2.4) likely because of higher risks of coronary heart disease (hazard ratio 1.8, 95% CI 1.1 to 3.1) and myocardial infarction (hazard ratio 2.1, 95% CI 1.0 to 4.7). Furthermore, when added to the Strong Heart Study Coronary Heart Disease Risk Calculator, QRS duration significantly improved prediction of future coronary heart disease events in women (Net Reclassification Index 0.17, 95% CI 0.06 to 0.47). In conclusion, QRS duration is an independent predictor of cardiovascular disease in women in the Strong Heart Study cohort and may have value in estimating risk in populations with similar risk profiles and a high lifetime incidence of cardiovascular disease.

Many studies have demonstrated that women are substantially underrepresented in cardiovascular trials, but few have considered that women develop cardiovascular disease at older ages than men. The extent to which observed gender enrollment inequalities persist after accounting for age-gender differences in disease prevalence is unknown. The purpose of the study was to compare observed rates of women participating in cardiovascular clinical trials with expected rates of female participation based on age- and gender-specific population disease prevalence. Publications between 1997 and 2009 in the three leading medical journals were included to calculate observed women's enrollment rates. Population-based data in Canada were used to determine the expected enrollment rates of women. Multicenter, randomized cardiovascular clinical trials that enrolled both men and women were analyzed. Two reviewers independently extracted data on women's enrollment and important clinical trial characteristics. The female enrollment rate was 30% in the included 325 trials, which ranged from 27% in trials of coronary artery disease, 27% in heart failure, 31% in arrhythmia, to 45% in primary prevention. Increased female enrollment correlated strongly with increasing age at recruitment in cardiovascular clinical trials (P disease prevalence, gaps in female enrollment were much lower than the expected enrollment rates estimated by 5% in coronary artery disease, 13% in heart failure, 9% in arrhythmia, and 3% in primary prevention. Only cardiovascular trials were evaluated in our study. Female underrepresentation in cardiovascular clinical trials is smaller than conventionally believed after accounting for age- and gender-specific population disease prevalence. Our findings suggest that greater representation of women in cardiovascular clinical trials can be achieved through the recruitment of older populations.

High-intensity concurrent training positively affects cardiovascular risk factors. Because this was never investigated in multiple sclerosis, the present pilot study explored the impact of this training on cardiovascular risk factors in this population. Before and after 12 weeks of high-intense concurrent training (interval and strength training, 5 sessions per 2 weeks, n = 16) body composition, resting blood pressure and heart rate, 2-h oral glucose tolerance (insulin sensitivity, glycosylated hemoglobin, blood glucose and insulin concentrations), blood lipids (high- and low-density lipoprotein, total cholesterol, triglyceride levels) and C-reactive protein were analyzed. Twelve weeks of high-intense concurrent training significantly improved resting heart rate (-6%), 2-h blood glucose concentrations (-13%) and insulin sensitivity (-24%). Blood pressure, body composition, blood lipids and C-reactive protein did not seem to be affected. Under the conditions of this pilot study, 12 weeks of concurrent high-intense interval and strength training improved resting heart rate, 2-h glucose and insulin sensitivity in multiple sclerosis but did not affect blood C-reactive protein levels, blood pressure, body composition and blood lipid profiles. Further, larger and controlled research investigating the effects of high-intense concurrent training on cardiovascular risk factors in multiple sclerosis is warranted. Implications for rehabilitation High-intensity concurrent training improves cardiovascular fitness. This pilot study explores the impact of this training on cardiovascular risk factors in multiple sclerosis. Despite the lack of a control group, high-intense concurrent training does not seem to improve cardiovascular risk factors in multiple sclerosis.

Full Text Available BACKGROUND: Randomised trials have highlighted the cardiovascular risks of non-steroidal anti-inflammatory drugs (NSAIDs in high doses and sometimes atypical settings. Here, we provide estimates of the comparative risks with individual NSAIDs at typical doses in community settings. METHODS AND FINDINGS: We performed a systematic review of community-based controlled observational studies. We conducted comprehensive literature searches, extracted adjusted relative risk (RR estimates, and pooled the estimates for major cardiovascular events associated with use of individual NSAIDs, in different doses, and in populations with low and high background risks of cardiovascular events. We also compared individual drugs in pair-wise (within study analyses, generating ratios of RRs (RRRs. Thirty case-control studies included 184,946 cardiovascular events, and 21 cohort studies described outcomes in >2.7 million exposed individuals. Of the extensively studied drugs (ten or more studies, the highest overall risks were seen with rofecoxib, 1.45 (95% CI 1.33, 1.59, and diclofenac, 1.40 (1.27, 1.55, and the lowest with ibuprofen, 1.18 (1.11, 1.25, and naproxen, 1.09 (1.02, 1.16.

Reproductive disorders, such as polycystic ovary syndrome (PCOS), primary ovarian insufficiency (POI) and hypertensive pregnancy disorders (HPD) like pre-eclampsia (PE), are associated with an increased risk of cardiovascular disease (CVD). Detection of early signs of cardiovascular disease (CVD), as well as identification of risk factors among women of reproductive age which improve cardiovascular risk prediction, is a challenge and current models might underestimate long-term health risks. The aim of this study is to assess cardiovascular disease in patients with a history of a reproductive disorder by low-dose computed tomography (CT). Women of 45 - 55 years, who experienced a reproductive disorder (PCOS, POI, HPD), are invited to participate in this multicenter, prospective, cohort study. Women will be recruited after regular cardiovascular screening, including assessment of classical cardiovascular risk factors. CT of the coronary arteries (both coronary artery calcium scoring (CACS), and contrast-enhanced coronary CT angiography (CCTA)) and carotid siphon calcium scoring (CSC) is planned in 300 women with HPD and 300 women with PCOS or POI. In addition, arterial stiffness (non-invasive pulse wave velocity (PWV)) measurement and cell-based biomarkers (inflammatory circulating cells) will be obtained. Initial inclusion is focused on women of 45 - 55 years. However, the age range (40 - 45 years and/or ≥ 55 years) and group composition may be adjusted based on the findings of the interim analysis. Participants can potentially benefit from information obtained in this study concerning their current cardiovascular health and expected future risk of cardiovascular events. The results of this study will provide insights in the development of CVD in women with a history of reproductive disorders. Ultimately, this study may lead to improved cardiovascular prediction models and will provide an opportunity for timely adjustment of preventive

Few studies addressing the relationship between food consumption and cardiovascular disease or metabolic risk have been conducted in children. Previous findings have indicated greater metabolic risk in children with high intakes of solid hydrogenated fat and white bread, and low consumption of fruits, vegetables and dairy products. In a large multinational sample of 2 to 9 years old children, high consumption of sweetened beverages and low intake of nuts and seeds, sweets, breakfast cereals, jam and honey and chocolate and nut-based spreads were directly associated with increased clustered cardiovascular disease risk. These findings add new evidence to the limited literature available in young populations on the role that diet may play on cardiovascular health. To investigate food consumption in relation to clustered cardiovascular disease (CVD) risk. Children (n = 5548, 51.6% boys) from eight European countries participated in the IDEFICS study baseline survey (2007-2008). Z-scores of individual CVD risk factors were summed to compute sex- and age-specific (2-chocolate and nut-based spreads (boys: OR = 0.46; 95% CI = 0.32-0.69; girls: OR = 0.60; 95% CI = 0.42-0.86), jam and honey (girls: OR = 0.45; 95% CI = 0.26-0.78) and sweets (boys: OR = 0.69; 95% CI = 0.48-0.98). OR of being at risk significantly increased with the highest consumption of soft drinks (younger boys) and manufactured juices (older girls). Concerning CVD risk score B, older boys and girls in the highest tertile of consumption of breakfast cereals were 0.41 (95% CI = 0.21-0.79) and 0.45 (95% CI = 0.22-0.93) times, respectively, less likely to be at risk than those in tertile 1. High consumption of sugar-sweetened beverages and low intake of breakfast cereals, jam and honey, sweets and chocolate and nut-based spreads seem to adversely affect clustered CVD risk. © 2012 The Authors.

Improving cardiovascular risk prediction continues to be a major challenge and effective prevention of cardiovascular disease. Accordingly, several studies have recently reported on the role of cardiovascular risk education. This study was designed to evaluate the impact of education on global cardiovascular risk in hypertensive patients. The study population consisted of 223 consecutive hypertensive outpatients. Their educational status was categorized according to the number of years of formal education as follows: (1) low education (less than 10 years) and (2) medium-high education (10-15 years).

It has often been suggested that cardiovascular mortality and their geographical heterogeneity are associated with nutrients intake patterns and also lipid profile. The large Spanish study Dieta y Riesgo de Enfermedades Cardiovasculares en España (DRECE) investigated this theory from 1991 to 2010. Out of the 4,783 Spanish individuals making up the DRECE cohort, 220 subjects (148 men and 72 women) died (4.62%) during the course of the study. The mean age of patients who died from cardiovascular causes (32 in all) was 61.08 years 95% CI (57.47-64.69) and 70.91% of them were males. The consumption of nutrients and the lipid profile by geographical area, studied by geospatial models, showed that the east and southern area of the country had the highest fat intake coupled to a high rate of unhealthy lipid profile. It was concluded that the spatial geographical analysis showed a relationship between high fat intake, unhealthy lipid profile and cardiovascular mortality in the different geographical areas, with a high variability within the country.

2014-03-01

Cardiovascular magnetic resonance (CMR) is a versatile non-invasive imaging modality that serves a broad spectrum of indications in clinical cardiology and has proven evidence. Most of the numerous applications are appropriate in patients with previous cardiovascular surgery in the same manner as in non-surgical subjects. However, some specifics have to be considered. This review article is intended to provide information about the application of CMR in adults with previous cardiovascular surgery. In particular, the two main scenarios, i.e. following coronary artery bypass surgery and following heart valve surgery, are highlighted. Furthermore, several pictorial descriptions of other potential indications for CMR after cardiovascular surgery are given.

2011-11-01

Full Text Available Abstract Background Chromosomal complement, including that provided by the sex chromosomes, influences expression of proteins and molecular signaling in every cell. However, less than 50% of the scientific studies published in 2009 using experimental animals reported sex as a biological variable. Because every cell has a sex, we conducted a literature review to determine the extent to which sex is reported as a variable in cardiovascular studies on cultured cells. Methods Articles from 10 cardiovascular journals with high impact factors (Circulation, J Am Coll Cardiol, Eur Heart J, Circ Res, Arterioscler Thromb Vasc Biol, Cardiovasc Res, J Mol Cell Cardiol, Am J Physiol Heart Circ Physiol, J Heart Lung Transplant and J Cardiovasc Pharmacol and published in 2010 were searched using terms 'cultured' and 'cells' in any order to determine if the sex of those cells was reported. Studies using established cell lines were excluded. Results Using two separate search strategies, we found that only 25 of 90 articles (28% and 20 of 101 articles (19.8% reported the sex of cells. Of those reporting the sex of cells, most (68.9%; n = 31 used only male cells and none used exclusively female cells. In studies reporting the sex of cells of cardiovascular origin, 40% used vascular smooth-muscle cells, and 30% used stem/progenitor cells. In studies using cells of human origin, 35% did not report the sex of those cells. None of the studies using neonatal cardiac myocytes reported the sex of those cells. Conclusions The complement of sex chromosomes in cells studied in culture has the potential to affect expression of proteins and 'mechanistic' signaling pathways. Therefore, consistent with scientific excellence, editorial policies should require reporting sex of cells used in in vitro experiments.

Dufouil, Carole; Seshadri, Sudha; Chêne, Geneviève

2014-01-01

There is growing evidence for the importance of cardiovascular risk factors in dementia development, including Alzheimer's disease. As cardiovascular risk profiles vary greatly by gender, with men suffering a greater burden of cardiovascular risk in midlife, this could lead to differences in dementia risk. To explore current evidence on the association between components of the cardiovascular risk profile and dementia risk in women and men, we reviewed all studies reporting the risk of dementia associated with cardiovascular risk factors stratified by gender and found 53 eligible articles out of over 4,000 published since the year 2000. Consistent results were found: 1) for exposures acting specifically in women: Overweight/obesity (harmful) and physical activity (protective), and 2) for exposures acting similarly in women and men: Moderate alcohol (protective) and hypertension, diabetes, and depression (harmful). A modified effect of tobacco or high cholesterol/statin use remained controversial. Available data do not allow us to assess whether selection of men with healthier cardiovascular profile (due to cardiovascular death in midlife) could lead in late life either to a difference in the distribution of risk factors or to a differential effect of these risk factors by gender. We recommend that results on dementia risk factors, especially cardiovascular ones, be reported systematically by gender in all future studies. More generally, as cardiovascular risk profiles evolve over time, more attention needs to be paid to the detection and correction of cardiovascular risk factors, as early as possible in the life course, and as actively in women as in men.

Economic literature shows that a child's future earnings are predictably influenced by parental income, providing an index of "socioeconomic mobility," or the ability of a person to move towards a higher socioeconomic status from childhood to adulthood. We adapted this economic paradigm to examine cardiovascular risk mobility (CRM), or whether there is life course mobility in relative cardiovascular risk. Participants from the BHS (Bogalusa Heart Study) with 1 childhood and 1 adult visit from 1973 to 2016 (n=7624) were considered. We defined population-level CRM as the rank-rank slope (β) from the regression of adult cardiovascular disease (CVD) risk percentile ranking onto childhood CVD risk percentile ranking (β=0 represents complete mobility; β=1 represents no mobility). After defining and measuring relative CRM, we assessed its correlation with absolute cardiovascular health using the American Heart Association's Ideal Cardiovascular Health metrics. Overall, there was substantial mobility, with black participants having marginally better CRM than whites (β black =0.10 [95% confidence interval, 0.05-0.15]; β white =0.18 [95% confidence interval, 0.14-0.22]; P =0.01). Having high relative CVD risk at an earlier age significantly reduced CRM (β age×slope =-0.02; 95% confidence interval, -0.03 to -0.01; P American Heart Association, Inc., by Wiley.

A review and rationale for studying the cardiovascular effects of drinking water arsenic in women of reproductive age

International Nuclear Information System (INIS)

Kwok, Richard K.

2007-01-01

Drinking water arsenic has been shown to be associated with a host of adverse health outcomes at exposure levels > 300 μg of As/L. However, the results are not consistent at exposures below this level. We have reviewed selected articles that examine the effects of drinking water arsenic on cardiovascular outcomes and present a rationale for studying these effects on women of reproductive age, and also over the course of pregnancy when they would potentially be more susceptible to adverse cardiovascular and reproductive outcomes. It is only recently that reproductive effects have been linked to drinking water arsenic. However, there is a paucity of information about the cardiovascular effects of drinking water arsenic on women of reproductive age. Under the cardiovascular challenge of pregnancy, we hypothesize that women with a slightly elevated exposure to drinking water arsenic may exhibit adverse cardiovascular outcomes at higher rates than in the general population. Studying sensitive clinical and sub-clinical indicators of disease in susceptible sub-populations may yield important information about the potentially enormous burden of disease related to low-level drinking water arsenic exposure

The relationship between bituminous coal quality and tectonic setting of the western part of upper Silesian coal Basin (USCB) of Poland

International Nuclear Information System (INIS)

Probierz, Krystian; Morga, Rafal

1997-01-01

Variation of quality parameters of coals occurring in selected geological structures in the western part of the Upper Silesian Coal Basin (USCB) was examined. It was ascertained that coals under research are characterised by high vitrinite content and medium rank (R o = 0.82 - 1.06%, V daf = 28.30 - 37.40%, RI = 19 - 89) and can be classified as para- and ortobituminous coals (ECE Geneva, 1993). Distribution of coal quality parameters was featured by different degree of concordance with spatial orientation of geological structures. In some cases (the Concordia over thrust, the anticline of Makoszowy fold) such concordance was revealed and it was proved that the structures were forming simultaneously with coalification process. In another two cases (the Klodnica fault, the Saara fault) concordance of this kind was not found. However, distribution of rank parameters allowed to reconstruct the sequence of the two processes, indicating that the faults formed after coalification. There were also cases (the Sosnica folds, the Ruda syncline) in which univocal relative timing of coalification and structure formation was not possible. The results obtained show, that presented method of analysis of spatial distribution of basic coal quality parameters within the deposit (above all R o , V daf , RI) can be used, similarly to optical anisotropy examination, for relative timing of geological structure formation and coalification process. It was confirmed, that knowledge of structure and geological history of a basin enables more precise prognosis of chemical - technological properties of coals. (Author)

Cardiovascular disease is the leading cause of adult mortality in India but data on the prevalence of cardiovascular risk factors are scarce, especially from North-east region of India. This study aims to assess the prevalence and the urban/tribal gradient of cardiovascular disease risk factors among healthy population of Tripura. A cross-sectional study was carried out among 238 healthy individuals (140 urban and 98 tribal) in one urban and five tribal areas of Tripura. Data was collected on sociodemographic profile, medical history, anthropometry, dietary patterns and addiction. Fasting blood samples were collected for biochemical analysis. Prevalence of cardiovascular disease risk factors and short-term cardiovascular disease risk score was calculated. The association of independent variables with 10-year cardiovascular disease risk score were examined by using multiple regression model. Prevalence of obesity, hypertension, diabetes, dyslipidaemia, metabolic syndrome and short-term cardiovascular disease risk score were higher in urban group. Urban people had higher salt, calories and fat intake. No difference was found in the addiction patterns of tobacco and alcohol but frequency and quantity being higher in tribal area. Dyslipidaemia and alcohol consumption showed significant positive association with 10-year cardiovascular disease risk score in both groups. While the non-sedentary lifestyle and dietary habits (low salt, low fat, carbohydrate predominant) of tribal population need to be promoted as a whole across the nation, they need to be protected from the adverse effects of rampant prevalence of tobacco and alcohol addiction among them. Urban population need to be extricated from adverse effects of sedentary lifestyle, modern food habits (high salt, high fat) and tobacco-alcohol addiction.

2008-10-01

In older adults without clinical cardiovascular disease, coronary artery calcium (CAC) is associated with other subclinical vascular diseases, which, in turn, predict physical dysfunction. However, the association between CAC and physical function is unstudied. In 387 older community-dwellers from the Cardiovascular Health Study without clinical cardiovascular diseases (mean age +/- standard deviation = 78.7 +/- 3.7, 35% men, 22% African Americans), CAC was measured using electron beam tomography, and physical performance was assessed by usual pace gait speed, chair stand, and tandem stand. Differences in physical performance across CAC quartiles were investigated in the whole cohort and by gender. Associations with gait speed (m/s) were assessed in multivariable models using both the continuous form of CAC score (log(CAC)) and quartiles of CAC, adjusting for demographics and comorbidities. No differences in physical performance were observed across CAC quartiles in the whole group. In gender-stratified analyses, a significant association was shown among women, who had progressively lower gait speed across CAC quartiles: Those with CAC > 220 walked more than 0.1 m/s slower than those with CAC or = 660) had a more than twofold odds of walking slower than 1 m/s, compared to the lowest CAC quartile (< 35; p =.021). In this sample of older community-dwellers without overt cardiovascular disease, CAC was inversely related to gait speed in women, but not in men.

Like other indigenous peoples, the Sami have been exposed to the huge pressures of colonisation, rapid modernisation and subsequent marginalisation. Previous studies among indigenous peoples show that colonialism, rapid modernisation and marginalisation is accompanied by increased stress, an unhealthy cardiovascular risk factor profile and disease burden. Updated data on the general burden of cardiovascular disease among the Sami is lacking. The primary objective of this study was to assess the relationship between marginalisation and self-reported lifetime cardiovascular disease (CVD) by minority/majority status in the rural Sami population of Norway. A cross-sectional population-based study (the SAMINOR study) was carried out in 2003-2004. The overall participation rate was 60.9% and a total of 4027 Sami individuals aged 36-79 years were included in the analyses. Data was collected by self-administrated questionnaires and a clinical examination. The logistic regression showed that marginalised Sami living in Norwegian dominated areas were more than twice as likely to report CVD as non-marginalised Sami living in Sami majority areas (OR 2.10, 95% CI: 1.40-3.14). No sex difference was found in the effects of marginalisation on self-reported life-time cardiovascular disease. Moderate to no intermediate effects were seen after including established CVD risk factors. This study showed that marginalised Sami living in Norwegian dominated areas were more than twice as likely as non-marginalised Sami from Sami majority areas to report lifetime cardiovascular disease (CVD). Moderate to no intermediate effects were seen after including established CVD risk factors, which suggest little difference in lifestyle related factors. Chronic stress exposure following marginalisation may however be a plausible explanation for some of the observed excess of CVD.

Sibutramine is an anorectic that has been banned since 2010 due to cardiovascular safety issues. However, counterfeit drugs or slimming products that include sibutramine are still available in the market. It has been reported that illegal sibutramine-contained pharmaceutical products induce cardiovascular crisis. However, the mechanism underlying sibutramine-induced cardiovascular adverse effect has not been fully evaluated yet. In this study, we performed cardiovascular safety pharmacology studies of sibutramine systemically using by hERG channel inhibition, action potential duration, and telemetry assays. Sibutramine inhibited hERG channel current of HEK293 cells with an IC50 of 3.92 μM in patch clamp assay and increased the heart rate and blood pressure (76 Δbpm in heart rate and 51 ΔmmHg in blood pressure) in beagle dogs at a dose of 30 mg/kg (per oral), while it shortened action potential duration (at 10 μM and 30 μM, resulted in 15% and 29% decreases in APD50, and 9% and 17% decreases in APD90, respectively) in the Purkinje fibers of rabbits and had no effects on the QTc interval in beagle dogs. These results suggest that sibutramine has a considerable adverse effect on the cardiovascular system and may contribute to accurate drug safety regulation.

Cardiovascular Reactivity, Stress, and Physical Activity

Full Text Available Psychological stress has been proposed as a major contributor to the progression of cardiovascular disease (CVD. Acute mental stress can activate the sympathetic-adrenal-medullary (SAM axis, eliciting the release of catecholamines (NE and EPI resulting in the elevation of heart rate (HR and blood pressure (BP. Combined stress (psychological and physical can exacerbate these cardiovascular responses, which may partially contribute to the elevated risk of CVD and increased proportionate mortality risks experienced by some occupations (e.g., firefighting and law enforcement. Studies have supported the benefits of physical activity on physiological and psychological health, including the cardiovascular response to acute stress. Aerobically trained individuals exhibit lower sympathetic nervous system (e.g., HR reactivity and enhanced cardiovascular efficiency (e.g., lower vascular reactivity and decreased recovery time in response to physical and/or psychological stress. In addition, resistance training has been demonstrated to attenuate cardiovascular responses and improve mental health. This review will examine stress-induced cardiovascular reactivity and plausible explanations for how exercise training and physical fitness (aerobic and resistance exercise can attenuate cardiovascular responses to stress. This enhanced functionality may facilitate a reduction in the incidence of stroke and myocardial infarction. Finally, this review will also address the interaction of obesity and physical activity on cardiovascular reactivity and CVD.

Main objective The aim of this study was to explore the perception of patients with cardiovascular disease towards oral health and the potential for cardiac care clinicians to promote oral health. Method A needs assessment was undertaken with twelve patients with cardiovascular disease attending cardiac rehabilitation between 2015 and 2016, in three metropolitan hospitals in Sydney, Australia. These patients participated in face-to-face semi-structured interviews. Data was analysed using thematic analysis. Results Results suggested that while oral health was considered relevant there was high prevalence of poor oral health among participants, especially those from socioeconomic disadvantaged background. Awareness regarding the importance of oral health care its impact on cardiovascular outcomes was poor among participants. Oral health issues were rarely discussed in the cardiac setting. Main barriers deterring participants from seeking oral health care included lack of awareness, high cost of dental care and difficulties in accessing the public dental service. Findings also revealed that participants were interested in receiving further information about oral health and suggested various mediums for information delivery. The concept of cardiac care clinicians, especially nurses providing education, assessment and referrals to ongoing dental care was well received by participants who felt the post-acute period was the most appropriate time to receive oral health care advice. The issues of oral health training for non-dental clinicians and how to address existing barriers were highlighted by participants. Relevance to clinical practice The lack of oral health education being provided to patients with cardiovascular disease offers an opportunity to improve care and potentially, outcomes.

Effects of torpedo blasting on rockburst prevention during deep coal seam mining in the Upper Silesian Coal Basin

Directory of Open Access Journals (Sweden)

Ł. Wojtecki

2017-08-01

Full Text Available In the Upper Silesian Coal Basin (USCB, coal seams are exploited under progressively more difficult geological and mining conditions (greater depth, higher horizontal stress, more frequent occurrence of competent rock layers, etc.. Mining depth, dislocations and mining remnants in coal seams are the most important factors responsible for the occurrence of rockburst hazards. Longwall mining next to the mining edges of neighbouring coal seams is particularly disadvantageous. The levels of rockburst hazards are minimised via the use of rockburst prevention methods. One active prevention method is torpedo blasting in roof rocks. Torpedo blastings are performed in order to decrease local stress concentrations in rock masses and to fracture the roof rocks to prevent or minimise the impact of high-energy tremors on excavations. The estimation of the effectiveness of torpedo blasting is particularly important when mining is under difficult geological and mining conditions. Torpedo blasting is the main form of active rockburst prevention in the assigned colliery in the Polish part of the USCB. The effectiveness of blasting can be estimated using the seismic effect method, in which the seismic monitoring data and the mass of explosives are taken into consideration. The seismic effect method was developed in the Czech Republic and is always being used in collieries in the Czech part of the coal basin. Now, this method has been widely adopted for our selected colliery in the Polish part of the coal basin. The effectiveness of torpedo blastings in the faces and galleries of the assigned longwall in coal seam 506 has been estimated. The results show that the effectiveness of torpedo blastings for this longwall was significant in light of the seismic effect method, which corresponds to the in situ observations. The seismic effect method is regularly applied to estimating the blasting effectiveness in the selected colliery.

Full Text Available Background: The purpose of this study is to evaluate the concentration of cardiovascular surgical procedures in a metropolitan area and investigate the perception of specialists regarding governmental policies to resolve this imbalance. Methods: From March to May 2015, surveys were distributed to members of the Thoracic and Cardiovascular Surgery Association. The final pool of research subjects consisted of 75 respondents. Subjects were queried regarding the concentration of cardiovascular operations in metropolitan areas, alternatives to the imbalance, and governmental policies to resolve the inequalities. Results: Survey participants responded that South Korea needs governmental policies to alleviate the concentration of cardiovascular surgery patients in large metropolitan hospitals. Participants agreed that the freedom to choose medical institutions and improved accessibility to metropolitan hospitals due to advanced transportation systems were some of the causes for the concentration. A majority (98.7% of respondents thought establishing thoracic and cardiovascular surgery centers in provinces was an appropriate solution to alleviate the concentration. Thoracic and cardiovascular surgery specialists were ranked as the number one group on which to focus development. Conclusion: Developing and carrying out policies to establish thoracic and cardiovascular surgery centers in provinces will alleviate the regional imbalance in available heart surgery services and an overall improvement in cardiovascular disease treatment in South Korea.

Cardiovascular diseases are still the leading cause of death in Spain. The DRECE study (Diet and Cardiovascular Disease Risk in Spain), based on a representative cohort of the Spanish general population, analyzed nutritional habits and lifestyle and their association with morbidity and mortality patterns. We estimated the impact, in terms of loss of productivity, of premature mortality attributed to cardiovascular diseases. The loss of productivity attributed to premature mortality was calculated from 1991, based on the potential years of life lost and the potential years of working life lost. During the 20-year follow-up of a cohort of 4779 patients, 225 of these patients died (men, 152). Sixteen percent of the deaths were attributed to cardiovascular disease. The costs due to lost productivity by premature mortality exceeded 29 million euros. Of these, 4 million euros (14% of the total cost) were due to cardiovascular causes. Premature cardiovascular mortality in the DRECE cohort represented a significant social cost due to lost productivity. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

Methods: We selected this region as a case territory for study because it is exposed to chronic ionizing radiation. The area is composed of coastal localities situated along the Techa River, into which liquid radioactive waste materials have been released. As a control, we selected settlements that were not subjected to ionizing radiation. Results: We found a statistically significant relationship between radioactive contamination of a territory and the prevalence of pathologies of the cardiovascular systems of people living in the Techa riverside villages (OR=2.31, p<0.001. The influence of covariates (gender, age, overweight status, and others on the development of cardiovascular pathologies was analyzed. Some of these factors have been recognized as confounding factors. After accounting for confounding factors, the odds ratio for the impact of radiation on the prevalence of pathologies of the cardiovascular system decreased to (OR=1.58, p=0.02. Conclusions: Statistically significant gender and age differences were observed in the prevalence of pathologies of the cardiovascular system in residents of radioactively contaminated areas compared to residents of control areas. These differences show a more pronounced reaction to contamination in older residents, residents with an overweight status and residents with meteotropic reactions.

The effect of the rank and of the maceral composition of bituminous coal on carbon dioxide sorption capacity was studied on the basis of samples from two coal mines (Darkov, CSM) from the Czech part of the Upper Silesian Basin. The samples from the two mines cover a small but very significant section of coalification within the transition zone between high-volatile bituminous A coal and medium-volatile bituminous coal, where porosity and sorption properties pass through their minima. The coal porous system was characterized by the micropore volume evaluated using the sorption isotherm of carbon dioxide and the volumes of meso-, macro- and coarse pores were determined by high-pressure mercury porosimetry. The micropore fraction in the coal porous system ranged between 53% and 75%. It was particularly high in coals with high vitrinite content, namely collotelinite, and also in coals with high inertinite content. The carbon dioxide sorption capacity was determined from the carbon dioxide sorption isotherms measured using a gravimetric sorption analyzer at 298 K until a relative pressure of 0.015 p/p{sub s}, and was interpreted by characteristic parameters of the Dubinin and Langmuir equations. It was found that the adsorbed amount of CO{sub 2} in the CSM coal increases with the content of vitrinite and collotelinite, whereas no increase or only a slight increase was observed for the Darkov coal. The tendency of adsorption capacity to depend on maceral composition, and also to some extent on coalification, observed for the CSM coal, may be related to higher microporosity due to the coalification process or oxidative processes leading to the formation of pseudovitrinite. 42 refs., 8 figs., 4 tabs.

Several studies have shown an increased risk for cardiovascular disease (CVD) in hyperthyroidism, but most studies have been too small to address the effect of hyperthyroidism on individual cardiovascular endpoints. Our main aim was to assess the association among hyperthyroidism, acute cardiovascular events and mortality. It is a nationwide population-based cohort study. Data were obtained from the Danish Civil Registration System and the Danish National Patient Registry, which covers all Danish hospitals. We compared the rate of all-cause mortality as well as venous thromboembolism (VTE), acute myocardial infarction (AMI), ischemic and non-ischemic stroke, arterial embolism, atrial fibrillation (AF) and percutaneous coronary intervention (PCI) in the two cohorts. Hazard ratios (HR) with 95% confidence intervals (95% CI) were estimated. The study included 85 856 hyperthyroid patients and 847 057 matched population-based controls. Mean follow-up time was 9.2 years. The HR for mortality was highest in the first 3 months after diagnosis of hyperthyroidism: 4.62, 95% CI: 4.40-4.85, and remained elevated during long-term follow-up (>3 years) (HR: 1.35, 95% CI: 1.33-1.37). The risk for all examined cardiovascular events was increased, with the highest risk in the first 3 months after hyperthyroidism diagnosis. The 3-month post-diagnosis risk was highest for atrial fibrillation (HR: 7.32, 95% CI: 6.58-8.14) and arterial embolism (HR: 6.08, 95% CI: 4.30-8.61), but the risks of VTE, AMI, ischemic and non-ischemic stroke and PCI were increased also 2- to 3-fold. We found an increased risk for all-cause mortality and acute cardiovascular events in patients with hyperthyroidism. © 2017 European Society of Endocrinology.

Overweight, obesity, and cardiovascular disease risk factors are prevalent among firefighters in some developed countries. It is unclear whether physical activity and cardiopulmonary fitness reduce cardiovascular disease risk and the cardiovascular workload at work in firefighters. The present study investigated the relationship between leisure-time physical activity, cardiopulmonary fitness, cardiovascular disease risk factors, and cardiovascular workload at work in firefighters in Hong Kong. Male firefighters (n = 387) were randomly selected from serving firefighters in Hong Kong (n = 5,370) for the assessment of cardiovascular disease risk factors (obesity, hypertension, diabetes mellitus, dyslipidemia, smoking, known cardiovascular diseases). One-third (Target Group) were randomly selected for the assessment of off-duty leisure-time physical activity using the short version of the International Physical Activity Questionnaire. Maximal oxygen uptake was assessed, as well as cardiovascular workload using heart rate monitoring for each firefighter for four "normal" 24-hour working shifts and during real-situation simulated scenarios. Overall, 33.9% of the firefighters had at least two cardiovascular disease risk factors. In the Target Group, firefighters who had higher leisure-time physical activity had a lower resting heart rate and a lower average working heart rate, and spent a smaller proportion of time working at a moderate-intensity cardiovascular workload. Firefighters who had moderate aerobic fitness and high leisure-time physical activity had a lower peak working heart rate during the mountain rescue scenario compared with firefighters who had low leisure-time physical activities. Leisure-time physical activity conferred significant benefits during job tasks of moderate cardiovascular workload in firefighters in Hong Kong.

Full Text Available Background & objectives: Studies conducted to assess the prevalence of cardiovascular (CV risk factors among different regions of the country show variation in risk factors in different age groups and urban and rural population. We undertook this study to determine the prevalence of cardiovascular risk factors among urban adults in a north Indian city. Methods: In a cross-sectional survey, 2227 subjects aged ≥ 20 yr were studied from April 2008 to June 2009 in Urban Chandigarh, a north Indian city. Demographic history, anthropometry and blood pressure were assessed. Fasting, and 2 h capillary plasma glucose after 75 g glucose load, HDL-C and triglycerides were estimated. Results: The most prevalent cardiovascular risk factors in the age group of 20-29 yr was sedentary lifestyle (63%, while from fourth decade and onwards, it was overweight/obesity (59-85%. The second most common prevalent cardiovascular risk factor in the age group of 20-29 yr was overweight/obesity, in 30-49 yr sedentary lifestyle, in 50-69 yr hypertension and in subjects ≥70 yr, it was hypertriglyceridaemia. The prevalence of overweight/obesity, hypertension, dysglycaemia and smoking was almost double in subjects in the fourth decade of life, as compared to those in the third decade of life. The prevalence of CV risk factors significantly increased with age irrespective of gender and prevalence of low HDL-C was significantly more common in women as compared to men. Interpretation & conclusions: Sedentary lifestyle, obesity and low HDL-C are the most prevalent CV risk factors in subjects in the third and fourth decade of life in this north Indian population and clustering of these cardiovascular risk factors increases with advancing age. Strategies need to be formulated to target this population to prevent the epidemic of cardiovascular disease.

Hyaluronic acid (HA) has been found to be an important trigger of atherosclerosis. In this study, we investigate the possible association of serum HA with cardiovascular disease risk in a population of low/intermediate risk for cardiovascular events. We enrolled 200 subjects with low/intermediate risk for developing cardiovascular disease. High specific C-reactive protein (hsCRP) was used as an indicator of preclinical atherosclerosis. The Framingham score was used to calculate the cardiovascular risk. Participants with dyslipidemia had significantly higher levels of serum HA than those without dyslipidemia (t-test, P = 0.05), higher levels of hsCRP (Kruskal-Wallis test, P = 0.04), and higher cardiovascular risk according to the Framingham score (Kruskal-Wallis test, P = 0.05). Serum HA concentration correlated significantly with the Framingham score for risk for coronary heart disease over the next 10 years (Spearman r = 0.152, P = 0.02). Diabetic volunteers had significantly higher HA than those without diabetes (t-test, P = 0.02). Participants with metabolic syndrome had higher serum HA levels and higher hsCRP (Kruskal-Wallis test, P = 0.01) compared to volunteers without metabolic syndrome (t-test, P = 0.03). Serum HA should be explored as an early marker of atheromatosis and cardiovascular risk. © 2016 Wiley Periodicals, Inc.

The focus of the study is the estimation of the effects of microgravity on the central nervous activity and its underlying influencing mechanisms. To validate the microgravity-induced physiological and psychological effects on EEG, quantitative EEG features, cardiovascular indicators, mood state, and cognitive performances data collection was achieved during a 45 day period using a -6°head-down bed rest (HDBR) integrated approach. The results demonstrated significant differences in EEG data, as an increased Theta wave, a decreased Beta wave and a reduced complexity of brain, accompanied with an increased heart rate and pulse rate, decreased positive emotion, and degraded emotion conflict monitoring performance. The canonical correlation analysis (CCA) based cardiovascular and cognitive related EEG model showed the cardiovascular effect on EEG mainly affected bilateral temporal region and the cognitive effect impacted parietal-occipital and frontal regions. The results obtained in the study support the use of an approach which combines a multi-factor influential mechanism hypothesis. The changes in the EEG data may be influenced by both cardiovascular and cognitive effects.

In the past twenty years the heaviest burden of cardiovascular diseases has begun to shift from developed to developing countries. However, little is known about the real needs for cardiovascular care in these countries and how well those needs are being met. This study aims to investigate the prevalence and determinants of unmet needs for cardiovascular care based on objective assessment. Multilevel analysis is used to analyse the determinants of met needs and multilevel multiple imputation is applied to manage missing data. The 2008 Indonesian Family Life Survey (IFLS4) survey is the source of the household data used in this study, while district data is sourced from the Ministry of Health and Ministry of Finance. The data shows that nearly 70% of respondents with moderate to high cardiovascular risk failed to receive cardiovascular care. Higher income, possession of health insurance and residence in urban areas are significantly associated with met needs for cardiovascular care, while health facility density and physician density show no association with them. The prevalence of unmet needs for cardiovascular care is considerable in Indonesia. Inequality persists as a factor in meeting needs for cardiovascular care as the needs of people with higher incomes and those living in urban areas are more likely to be met. Alleviation of poverty, provision of health care insurance for the poor, and improvement in the quality of healthcare providers are recommended in order to meet this ever-increasing need.

There is increasing evidence for a protective effect of tea consumption against cardiovascular disease. This review summarizes the available epidemiological data providing evidence for and against such an effect. We also review observational and intervention studies that investigated an effect of tea and tea extracts on cardiovascular risk factors, including blood pressure, serum lipids, diabetes mellitus, and obesity. Finally, we review potential mechanisms of benefit, including anti-inflammatory, anti-oxidant, and anti-proliferative effects, as well as favorable effects on endothelial function. Overall, the observational data suggest a benefit, but results are mixed and likely confounded by lifestyle and background dietary factors. The weight of evidence indicates favorable effects on risk factors and a number of plausible mechanisms have been elucidated in experimental and translational human studies. Despite the growing body evidence, it remains uncertain whether tea consumption should be recommended to the general population or to patients as a strategy to reduce cardiovascular risk.

Objective To investigate whether there is an increased risk of cardiovascular events in people who exhibit iatrogenic Cushing’s syndrome during treatment with glucocorticoids. Design Cohort study. Setting 424 UK general practices contributing to The Health Improvement Network database. Participants People prescribed systemic glucocorticoids and with a diagnosis of iatrogenic Cushing’s syndrome (n=547) and two comparison groups: those prescribed glucocorticoids and with no diagnosis of iatrogenic Cushing’s syndrome (n=3231) and those not prescribed systemic glucocorticoids (n=3282). Main outcome measures Incidence of cardiovascular events within a year after diagnosis of iatrogenic Cushing’s syndrome or after a randomly selected date, and association between iatrogenic Cushing’s syndrome and risk of cardiovascular events. Results 417 cardiovascular events occurred in 341 patients. Taking into account only the first event by patient (coronary heart disease n=177, heart failure n=101, ischaemic stroke n=63), the incidence rates of cardiovascular events per 100 person years at risk were 15.1 (95% confidence interval 11.8 to 18.4) in those prescribed glucocorticoids and with a diagnosis of iatrogenic Cushing’s syndrome, 6.4 (5.5 to 7.3) in those prescribed glucocorticoids without a diagnosis of iatrogenic Cushing’s syndrome, and 4.1 (3.4 to 4.8) in those not prescribed glucocorticoids. In multivariate analyses adjusted for sex, age, intensity of glucocorticoid use, underlying disease, smoking status, and use of aspirin, diabetes drugs, antihypertensive drugs, lipid lowering drugs, or oral anticoagulant drugs, the relation between iatrogenic Cushing’s syndrome and cardiovascular events was strong (adjusted hazard ratios 2.27 (95% confidence interval 1.48 to 3.47) for coronary heart disease, 3.77 (2.41 to 5.90) for heart failure, and 2.23 (0.96 to 5.17) for ischaemic cerebrovascular events).

There are increasing concerns about risks associated with aspirin discontinuation in the absence of major surgery or bleeding. We investigated whether long-term low-dose aspirin discontinuation and treatment gaps increase the risk of cardiovascular events. We performed a cohort study of 601 527 users of low-dose aspirin for primary or secondary prevention in the Swedish prescription register between 2005 and 2009 who were >40 years of age, were free from previous cancer, and had ≥80% adherence during the first observed year of treatment. Cardiovascular events were identified with the Swedish inpatient and cause-of-death registers. The first 3 months after a major bleeding or surgical procedure were excluded from the time at risk. During a median of 3.0 years of follow-up, 62 690 cardiovascular events occurred. Patients who discontinued aspirin had a higher rate of cardiovascular events than those who continued (multivariable-adjusted hazard ratio, 1.37; 95% confidence interval, 1.34-1.41), corresponding to an additional cardiovascular event observed per year in 1 of every 74 patients who discontinue aspirin. The risk increased shortly after discontinuation and did not appear to diminish over time. In long-term users, discontinuation of low-dose aspirin in the absence of major surgery or bleeding was associated with a >30% increased risk of cardiovascular events. Adherence to low-dose aspirin treatment in the absence of major surgery or bleeding is likely an important treatment goal. © 2017 American Heart Association, Inc.

Implementation of a Cardiovascular Disease Prevention Program among School-Aged Children: A Pilot Study

Lavon Young

2006-09-01

Full Text Available The objective of this study was to test students’ knowledge of cardiovascular disease information and to determine if a carefully structured training program administered to high school students would increase their knowledge about cardiovascular disease and risk factors that are preventable. A pilot study was conducted during which fifty high school students from nine counties in the State of Mississippi were measured for their knowledge of hypertension both at baseline and after the completion of an intervention training activity. There were significant gains in knowledge between the pre-test and the post-test that the students completed. The gains in knowledge indicate that elimination of risk factors is possible if all health care and school-based prevention programs are implemented to positively impact changes in eating and physical activity behaviors. Students’ involvement in such activities could translate into significant changes in risk factors at these ages and throughout their lifetime. It is widely accepted that these behavioral changes, if sustained into adulthood, could have the potential to influence cardiovascular risk reduction.

The association between daily cardiovascular/respiratory mortality and air pollution in an urban district of Beijing was investigated over a 6-year period (January 2003 to December 2008). The purpose of this study was to evaluate the relative importance of the major air pollutants [particulate matter (PM), SO2, NO2] as predictors of daily cardiovascular/respiratory mortality. The time-series studied comprises years with lower level interventions to control air pollution (2003-2006) and years with high level interventions in preparation for and during the Olympics/Paralympics (2007-2008). Concentrations of PM10, SO2, and NO2, were measured daily during the study period. A generalized additive model was used to evaluate daily numbers of cardiovascular/respiratory deaths in relation to each air pollutant, controlling for time trends and meteorological influences such as temperature and relative humidity. The results show that the daily cardiovascular/respiratory death rates were significantly associated with the concentration air pollutants, especially deaths related to cardiovascular disease. The current day effects of PM10 and NO2 were higher than that of single lags (distributed lags) and moving average lags for respiratory disease mortality. The largest RR of SO2 for respiratory disease mortality was in Lag02. For cardiovascular disease mortality, the largest RR was in Lag01 for PM10, and in current day (Lag0) for SO2 and NO2. NO2 was associated with the largest RRs for deaths from both cardiovascular disease and respiratory disease.

Full Text Available Abstract Background The increasing burden of cardiovascular diseases (CVD in the ageing population of industrialized nations requires an intensive search for means of reducing this epidemic. In order to improve prevention, detection, therapy and prognosis of cardiovascular diseases on the population level in Eastern Germany, it is necessary to examine reasons for the East-West gradient of CVD morbidity and mortality, potential causal mechanisms and prognostic factors in the elderly. Psychosocial and nutritional factors have previously been discussed as possible causes for the unexplained part of the East-West gradient. A reduced heart rate variability appears to be associated with cardiovascular disease as well as with psychosocial and other cardiovascular risk factors and decreases with age. Nevertheless, there is a lack of population-based data to examine the role of heart rate variability and its interaction with psychosocial and nutritional factors regarding the effect on cardiovascular disease in the ageing population. There also is a paucity of epidemiological data describing the health situation in Eastern Germany. Therefore, we conduct a population-based study to examine the distribution of CVD, heart rate variability and CVD risk factors and their associations in an elderly East German population. This paper describes the design and objectives of the CARLA Study. Methods/design For this study, a random sample of 45–80 year-old inhabitants of the city of Halle (Saale in Eastern Germany was drawn from the population registry. By the end of the baseline examination (2002–2005, 1750 study participants will have been examined. A multi-step recruitment strategy aims at achieving a 70 % response rate. Detailed information is collected on own and family medical history, socioeconomic, psychosocial, behavioural and biomedical factors. Medical examinations include anthropometric measures, blood pressure of arm and ankle, a 10-second and a 20

of morphological and tomographic (CT) studies of the skull that was found in the crypt of the Silesian Piasts in the St. Jadwiga church in Brzeg (Silesia, Poland) are presented and discussed here. The established date of burial of probably a 20-30 years old male was 16th-17th century. The analyzed skull showed premature obliteration of the major skull sutures. It resulted in the braincase deformation, similar to the forms found in oxycephaly and microcephaly. Tomographic analysis revealed gross pathology. Signs of increased intracranial pressure, basilar invagination and hypoplasia of the occipital bone were observed. Those results suggested the occurrence of the very rare Arnold-Chiari syndrome. Lesions found in the sella turcica indicated the development of pituitary macroadenoma, which resulted in the occurrence of discreet features of acromegaly in the facial bones. The studied skull was characterized by a significantly smaller size of the neurocranium (horizontal circumference 471 mm, cranial capacity ∼ 1080 ml) and strongly expressed brachycephaly (cranial index=86.3), while its height remained within the range for non-deformed skulls. A narrow face, high eye-sockets and prognathism were also observed. Signs of alveolar process hypertrophy with rotation and displacement of the teeth were noted. The skull showed significant morphological differences compared to both normal and other pathological skulls such as those with pituitary gigantism, scaphocephaly and microcephaly.

Cardiovascular risk equations are traditionally derived from the Framingham Study. The accuracy of this approach in Asian populations, where resources for risk factor measurement may be limited, is unclear. To compare "low-information" equations (derived using only age, systolic blood pressure, total cholesterol and smoking status) derived from the Framingham Study with those derived from the Asian cohorts, on the accuracy of cardiovascular risk prediction. Separate equations to predict the 8-year risk of a cardiovascular event were derived from Asian and Framingham cohorts. The performance of these equations, and a subsequently "recalibrated" Framingham equation, were evaluated among participants from independent Chinese cohorts. Six cohort studies from Japan, Korea and Singapore (Asian cohorts); six cohort studies from China; the Framingham Study from the US. 172,077 participants from the Asian cohorts; 25,682 participants from Chinese cohorts and 6053 participants from the Framingham Study. In the Chinese cohorts, 542 cardiovascular events occurred during 8 years of follow-up. Both the Asian cohorts and the Framingham equations discriminated cardiovascular risk well in the Chinese cohorts; the area under the receiver-operator characteristic curve was at least 0.75 for men and women. However, the Framingham risk equation systematically overestimated risk in the Chinese cohorts by an average of 276% among men and 102% among women. The corresponding average overestimation using the Asian cohorts equation was 11% and 10%, respectively. Recalibrating the Framingham risk equation using cardiovascular disease incidence from the non-Chinese Asian cohorts led to an overestimation of risk by an average of 4% in women and underestimation of risk by an average of 2% in men. A low-information Framingham cardiovascular risk prediction tool, which, when recalibrated with contemporary data, is likely to estimate future cardiovascular risk with similar accuracy in Asian

Hepatitis C virus and cardiovascular: A review

Salvatore Petta

2017-03-01

Full Text Available Chronic hepatitis C virus (HCV infection is a systemic disease that leads to increased risks of cirrhosis and its complications, as well as extrahepatic disturbances, including immune-related disorders and metabolic alterations such as insulin resistance and steatosis. Recent accumulating evidence suggests that HCV infection can increase cardiovascular risk, and that viral eradication can improve cardiovascular outcomes in the clinical setting. These data are strengthened by evidence identifying potential mechanisms (indirectly linking HCV infection to vascular damage. However, the high prevalence of both HCV infection and cardiovascular alterations, as well as the presence of contrasting results not identifying any association between HCV infection and cardiovascular dysfunction, provides uncertainty about a direct association of HCV infection with cardiovascular risk. Further studies are needed to clarify definitively the role of HCV infection in cardiovascular alterations, as well as the impact of viral eradication on cardiovascular outcomes. These features are now more attractive, considering the availability of new, safe, and very effective interferon-free antiviral agents for the treatment of HCV infection. This review aims to discuss carefully available data on the relationship between HCV infection and cardiovascular risk.

Full Text Available Abstract Background Cardiovascular magnetic resonance (CMR can provide quantitative data of the myocardial tissue utilizing high spatial and temporal resolution along with exquisite tissue contrast. Previous studies have correlated myocardial scar tissue with the occurrence of ventricular arrhythmia. This study was conducted to evaluate whether characterization of myocardial infarction by CMR can predict cardiovascular events in patients with ischemic cardiomyopathy (ICM. Results We consecutively studied 86 patients with ICM (LVEF Conclusion Quantification of the scar volume and scar percentage by CMR is superior to LVEDV, LVESV, and LVEF in prognosticating the future likelihood of the development of cardiovascular events in patients with ICM.

Full Text Available As men grow older, testosterone (T levels decline and the significance of this change is debated. The evidence supporting a causal role for lower circulating T, or its metabolites dihydrotestosterone (DHT and estradiol, in the genesis of atherosclerosis and cardiovascular disease (CVD in men is limited. Observational studies associate low baseline T levels with carotid atherosclerosis, aortic and peripheral vascular disease, and with the incidence of cardiovascular events and mortality. Studies using mass spectrometry suggest that when total T is assayed optimally, calculation of free T might not necessarily improve risk stratification. There is limited evidence to support an association of estradiol with CVD. Interventional studies of T therapy in men with coronary artery disease have shown beneficial effects on exercise-induced myocardial ischemia. However, placebo-controlled, randomized clinical trials (RCTs of T therapy in men with the prespecified outcomes of cardiovascular events or deaths are lacking. Meta-analyses of randomized controlled trials of T published up to 2010 found no increase in cardiovascular events, mortality, or prostate cancer with therapy. Recently, in a trial of older men with mobility limitations, men randomized to receive a substantial dose of T reported cardiovascular adverse effects. This phenomenon was not reported from a comparable trial where men received a more conservative dose of T, suggesting a prudent approach should be adopted when considering therapy in frail older men with existing CVD. Adequately powered RCTs of T in middle-aged and older men are needed to clarify whether or not hormonal intervention would reduce the incidence of CVD.

Nutritional studies focus on traditional cultural models and lifestyles in different countries. The aim of this study was to examine the adherence to the Mediterranean diet, life habits, and risk factors associated with cardiovascular diseases among people living in different geographical regions in Spain. A descriptive cross-sectional study was conducted in each region. The sampling scheme consisted of a random three-stage stratified sampling program according to geographic region, age, and gender. A total of 1732 subjects were asked to complete a questionnaire designed to assess their nutrient intake, dietary habits, and exercise. A diet score that assesses the adherence of participants to the Mediterranean diet (range 0-10) was also applied. Southeastern Spain had the lowest score for adherence to the Mediterranean diet because of the low consumption of fish and plant products. A lower adherence score to the Mediterranean diet was strongly associated with the prevalence of hypertension ( p = 0.018). A low level of adherence to the Mediterranean diet is accompanied by a high prevalence of hypertension and, therefore, a raised cardiovascular risk in the country. The adherence score could help identify individuals at greater cardiovascular risk.

Full Text Available Comprehensive environmental studies taking under consideration the structure of the radiation balance during the vegetation growing seasons of 2001 and 2002 were carried out on the open sandy surface of the area called the Błędów ‘desert’ located on Silesian Upland. The research in each site covered the composition of plant species, their age and height, the condition of the substratum, the composition and structure of the soil and the meteorological conditions with elements of the radiation balance. The article presents some part of the research on meteorological elements and their impact on ecosystem. Special attention was devoted to radiation conditions on the open sandy surface in the context of the formation of BSC (biological soil crust. Having presumed that the values obtained on the grassy surface constituted 100%, the values of radiation reflection measured on the open sandy surface were 185% higher and the values of net longwave radiation were 105% higher in day time and 137% in night time. Values of net radiation of about 63% lower were observed on the sandy surface during a typical sunny summer day. It was found that a strong irradiation of the sandy surface (26 MJ·m–2d–1 creates extremely difficult conditions for the initiation of the process of ecosystem formation (including BSC or plant succession. The elements of the radiation balance, net radiation, albedo and temperature of the open sandy surface were represented quantitatively. The test surfaces were classified based on the value of the albedo: group I with low albedo values, up to 0.15 (spore-bearing plants on a dark surface, including BSC; group II with mean values of the albedo from 0.16 to 0.24 (spore-bearing plants and seed on a dark grey surface; and group III with high albedo values, above 0.25 (plants growing on bare or loose sands.

Atherogenic dyslipidemia is associated with poor cardiovascular outcomes, yet markers of this condition are often ignored in clinical practice. Here, we address a clear evidence gap by assessing the prevalence and treatment of two markers of atherogenic dyslipidemia: elevated triglyceride levels and low levels of high-density lipoprotein cholesterol. This cross-sectional observational study assessed the prevalence of two atherogenic dyslipidemia markers, high triglyceride levels and low high-density lipoprotein cholesterol levels, in the study population from the European Study on Cardiovascular Risk Prevention and Management in Usual Daily Practice (EURIKA; N = 7641; of whom 51.6% were female and 95.6% were White/Caucasian). The EURIKA population included European patients, aged at least 50 years with at least one cardiovascular risk factor but no history of cardiovascular disease. Over 20% of patients from the EURIKA population have either triglyceride or high-density lipoprotein cholesterol levels characteristic of atherogenic dyslipidemia. Furthermore, the proportions of patients with one of these markers were higher in subpopulations with type 2 diabetes mellitus or those already calculated to be at high risk of cardiovascular disease. Approximately 55% of the EURIKA population who have markers of atherogenic dyslipidemia are not receiving lipid-lowering therapy. A considerable proportion of patients with at least one major cardiovascular risk factor in the primary cardiovascular disease prevention setting have markers of atherogenic dyslipidemia. The majority of these patients are not receiving optimal treatment, as specified in international guidelines, and thus their risk of developing cardiovascular disease is possibly underestimated. The present study is registered with ClinicalTrials.gov (ID: NCT00882336).

The Mediterranean diet, its components, and cardiovascular disease.

One of the best-studied diets for cardiovascular health is the Mediterranean diet. This consists of fish, monounsaturated fats from olive oil, fruits, vegetables, whole grains, legumes/nuts, and moderate alcohol consumption. The Mediterranean diet has been shown to reduce the burden, or even prevent the development, of cardiovascular disease, breast cancer, depression, colorectal cancer, diabetes, obesity, asthma, erectile dysfunction, and cognitive decline. This diet is also known to improve surrogates of cardiovascular disease, such as waist-to-hip ratio, lipids, and markers of inflammation, as well as primary cardiovascular disease outcomes such as death and events in both observational and randomized controlled trial data. These enhancements easily rival those seen with more established tools used to fight cardiovascular disease such as aspirin, beta-blockers, angiotensin-converting enzyme inhibitors, and exercise. However, it is unclear if the Mediterranean diet offers cardiovascular disease benefit from its individual constituents or in aggregate. Furthermore, the potential benefit of the Mediterranean diet or its components is not yet validated by concrete cardiovascular disease endpoints in randomized trials or observational studies. This review will focus on the effects of the whole and parts of the Mediterranean diet with regard to both population-based and experimental data highlighting cardiovascular disease morbidity or mortality and cardiovascular disease surrogates when hard outcomes are not available. Our synthesis will highlight the potential for the Mediterranean diet to act as a key player in cardiovascular disease prevention, and attempt to identify certain aspects of the diet that are particularly beneficial for cardioprotection.

To summarize evidence about the association between daytime napping and the risk of cardiovascular disease and all-cause mortality, and to quantify the potential dose-response relation. Meta-analysis of prospective cohort studies. Electronic databases were searched for articles published up to December 2014 using the terms nap, cardiovascular disease, and all-cause mortality. We selected well-adjusted prospective cohort studies reporting risk estimates for cardiovascular disease and all-cause mortality related to napping. Eleven prospective cohort studies were identified with 151,588 participants (1,625,012 person-years) and a mean follow-up period of 11 years (60% women, 5,276 cardiovascular events, and 18,966 all-cause deaths). Pooled analysis showed that a long daytime nap (≥ 60 min/day) was associated with a higher risk of cardiovascular disease (rate ratio [RR]: 1.82 [1.22-2.71], P = 0.003, I(2) = 37%) compared with not napping. All-cause mortality was associated with napping for ≥ 60 min/day (RR: 1.27 [1.11-1.45], P napping. In contrast, napping for nap time and cardiovascular disease (P for nonlinearity = 0.01). The RR initially decreased from 0 to 30 min/day. Then it increased slightly until about 45 min/day, followed by a sharp increase at longer nap times. There was also a positive linear relation between nap time and all-cause mortality (P for non-linearity = 0.97). Nap time and cardiovascular disease may be associated via a J-curve relation. Further studies are needed to confirm the efficacy of a short nap. © 2015 Associated Professional Sleep Societies, LLC.

We assessed the cardiovascular safety of liraglutide, a glucagon-like peptide-1 receptor agonist, using existing clinical data. Patient-level results from all completed phase 2 and 3 studies from the liraglutide clinical development programme were pooled to determine rates of major adverse cardiovascular events (MACE): cardiovascular death, myocardial infarction, stroke. MACE were identified by querying the study database using Medical Dictionary for Regulatory Activities (MedDRA) terms combined with serious adverse events recorded by study investigators. Broad, narrow, and custom groups of MedDRA queries were used. Candidate events from each query were independently adjudicated post hoc. In 15 studies (6638 patients; 4257 liraglutide treated), there were 114 patients with MACE identified using the broad MedDRA query. Of these, 44 were classified as serious adverse events and 39 were adjudicated as MACE. The incidence ratio for adjudicated broad/serious MACE associated with liraglutide was 0.73 (95% CI 0.38-1.41) versus all comparator drugs (metformin, glimepiride, rosiglitazone, insulin glargine, placebo), within cardiovascular safety limits defined by the United States Food & Drug Administration for diabetes therapies under current investigation.

Disease prevention should begin in childhood and lifestyles are important risk determinants of cardiovascular disease. Awareness and monitoring of risk is essential in preventive strategies. To characterize cardiovascular risk and the relationships between certain variables in adolescents. In a cross-sectional study, 854 adolescent schoolchildren were surveyed, mean age 16.3 ± 0.9 years. Data collection included questionnaires, physical examination, charts for 10-year relative risk of mortality, and biochemical assays. In the statistical analysis continuous variables were studied by the Student's t test and categorical variables by the chi-square test and Fisher's exact test, and each risk factor was entered as a dependent variable in logistic regression analysis. Physical activity was insufficient in 81% of students. The daily consumption of soup, salad or vegetables, and fruit was, respectively, 37%, 39% and 21%. A minority (6%) took ≤ 3 and 77% took ≥ 5 meals a day. The prevalence of each risk factor was as follows: overweight 16%; smoking 13%; hypertension 11%; impaired glucose metabolism 9%; hypertriglyceridemia 9%; and hypercholesterolemia 5%. Out-of-school physical activity, hypertension and overweight were more prevalent in males (p<0.001). Females had higher levels of cholesterol (p<0.005) and triglycerides (p<0.001). A quarter of the adolescents had a relative risk score for 10-year cardiovascular mortality of ≥ 2. Overweight showed a positive association with blood pressure, changes in glucose metabolism and triglycerides, and a negative association with number of daily meals. The results demonstrate the need for action in providing and encouraging healthy choices for adolescents, with an emphasis on behavioral and lifestyle changes aimed at individuals, families and communities.

To evaluate the dietary micronutrient intake in the adult Spanish population participating in the DRECE study. The cross-sectional study was performed in two stages in 1991 and 1996 in 43 primary care clinics. One thousand two hundred people 'with cardiovascular risk' and 600 'without risk' answered a food frequency questionnaire. Significant increases in vitamin C, retinol, lycopenes, beta-cryptoxanthin and vitamin E intakes were found. Vitamin A, alpha-carotenoid and lutein intakes decreased. Vitamin B(12), B(6) and folic acid intakes increased in people with cardiovascular risk, whereas only the last two increased in the control group. Nearly 100% of the people consumed the recommended dietary allowances for vitamins B(12) and B(6) and >70% for folic acid. Calcium, iron, and zinc intake increased in both groups, but magnesium and selenium intake increased only in people at risk. Vitamin A, B(1) and zinc intakes have decreased, and >50% of the people do not consume the recommended dietary allowance. Antioxidant vitamins and vitamin B(12), B(6) and folic acid intakes seem to be adequate in the adult Spanish population, no significant differences appear regarding their cardiovascular risk status. Vitamin A, B(1) and zinc intakes are not appropriate. Copyright 2000 S. Karger AG, Basel.

Review of studies about epidemiological and physiopathological knowledge of ambient air particles short-term cardio-vascular effects. CURRENTS AND STRONG POINTS: Many studies, in contrasted countries for pollution's sources, meteorological conditions or socio-demographical characteristics, have shown health effects due to ambient air particles. After having studied mainly the respiratory effects of particulate air pollution, epidemiologists are now interested in the cardio-vascular effects of ambient air particles. In fact, serious effects seem to exist in fragile people which can get to emergency department visits, hospitalisation and even death. In addition, studies have shown less serious effects, but likely to be frequent (cardiac symptoms, and stoppages for cardio-vascular causes, notably). The exact mechanism by which particles have cardio-vascular adverse health effects is unknown, but experimental and epidemiological studies have led to several hypotheses: local pulmonary effects seem to be followed by systemic effects, which would be responsible for effects on the electrical activity of the heart through cardiac autonomic dysfunction and effects on the blood supply to the heart. The objective of this work is to summarise epidemiological and physiopathological knowledge about the cardio-vascular effects of ambient air particles. To evaluate the real importance of cardio-vascular effects due to particulate air pollution and to identify their exact mechanism, a more precise knowledge of detailed causes of deaths and hospitalisations and a better knowledge of less serious effects, but likely to be frequent, is necessary. Equally, a detailed identification of fragile people is essential for developing preventive actions.

The results from mandatory cardiovascular outcome trials (CVOTs are therefore of great interest in the field. The Academy for Cardiovascular Risk, Outcomes and Safety Studies in Type 2 Diabetes meeting program aims to bring together experts from several associated disciplines to provide fair and balanced resources for those involved in the management of patients with T2D. This publication represents the opinions of the faculty on the key learnings from the meeting held in Vienna in the spring of 2017. In particular, we detail how data from the EMPA-REG OUTCOME® [cardiovascular outcomes trial of empagliflozin] and Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcome Results (LEADER® (liraglutide CVOTs can be practically interpreted across clinical specialities.

LA-ICP-MS U-Pb apatite dating of Lower Cretaceous rocks from teschenite-picrite association in the Silesian Unit (southern Poland

Directory of Open Access Journals (Sweden)

Szopa Krzysztof

2014-08-01

Full Text Available The main products of volcanic activity in the teschenite-picrite association (TPA are shallow, sub-volcanic intrusions, which predominate over extrusive volcanic rocks. They comprise a wide range of intrusive rocks which fall into two main groups: alkaline (teschenite, picrite, syenite, lamprophyre and subalkaline (dolerite. Previous 40Ar/39Ar and 40K/40Ar dating of these rocks in the Polish Outer Western Carpathians, performed on kaersutite, sub-silicic diopside, phlogopite/biotite as well as on whole rock samples has yielded Early Cretaceous ages. Fluorapatite crystals were dated by the U-Pb LA-ICP-MS method to obtain the age of selected magmatic rocks (teschenite, lamprophyre from the Cieszyn igneous province. Apatite-bearing samples from Boguszowice, Puńców and Lipowa yield U-Pb ages of 103± 20 Ma, 119.6 ± 3.2 Ma and 126.5 ± 8.8 Ma, respectively. The weighted average age for all three samples is 117.8 ± 7.3 Ma (MSWD = 2.7. The considerably smaller dispersion in the apatite ages compared to the published amphibole and biotite ages is probably caused by the U-Pb system in apatite being less susceptible to the effects of hydrothermal alternation than the 40Ar/39Ar or 40K/40Ar system in amphibole and/or biotite. Available data suggest that volcanic activity in the Silesian Basin took place from 128 to 103 Ma with the the main magmatic phase constrained to 128-120 Ma.

Cardiovascular diseases are the main cause of morbidity and mortality in Malaysia. There is evidence of high traditional and complementary medicine (TCM) use among population with cardiovascular risk and there have been anecdotal reports about substitution of conventional medicines with TCM. We investigated the prevalence of TCM use, treatment preference and substitution of conventional medicines in study population with cardiovascular risk factors in Pahang, Malaysia. A cross-sectional survey was conducted using an interviewer-administered questionnaire in five districts of Pahang. A total of 1250 households were chosen through proportionate and systematic sampling. Respondents aged 18 years and above were selected. The study population with cardiovascular risk factors who used TCM was higher than the general population (31.7% versus 25.9%). There were no clear preferences in using TCM by gender, age groups, educational level and income even though other bumiputeras showed a slight inclination towards TCM use. Among the study population with cardiovascular risk factors who consumed TCM, 20-30% of them were using TCM as a substitute for their conventional medications. Respondents from the younger age group (18-40 years) (57.1%), highest educational level (43.2%), other bumiputeras (38.4%) and highest income group (31.4%) preferred the combination of both conventional and traditional medicine. TCM use among population with cardiovascular risk factors is high. The high preference for combination therapy of TCM and conventional medications among young adults and the use of TCM to substitute conventional medications show that much research is needed to provide proven TCM therapies to avoid self-mismanagement of cardiovascular risk in Malaysia.

Full Text Available The association between daily cardiovascular/respiratory mortality and air pollution in an urban district of Beijing was investigated over a 6-year period (January 2003 to December 2008. The purpose of this study was to evaluate the relative importance of the major air pollutants [particulate matter (PM, SO2, NO2] as predictors of daily cardiovascular/respiratory mortality. The time-series studied comprises years with lower level interventions to control air pollution (2003–2006 and years with high level interventions in preparation for and during the Olympics/Paralympics (2007–2008. Concentrations of PM10, SO2, and NO2, were measured daily during the study period. A generalized additive model was used to evaluate daily numbers of cardiovascular/ respiratory deaths in relation to each air pollutant, controlling for time trends and meteorological influences such as temperature and relative humidity. The results show that the daily cardiovascular/respiratory death rates were significantly associated with the concentration air pollutants, especially deaths related to cardiovascular disease. The current day effects of PM10 and NO2 were higher than that of single lags (distributed lags and moving average lags for respiratory disease mortality. The largest RR of SO2 for respiratory disease mortality was in Lag02. For cardiovascular disease mortality, the largest RR was in Lag01 for PM10, and in current day (Lag0 for SO2 and NO2. NO2 was associated with the largest RRs for deaths from both cardiovascular disease and respiratory disease.

Cardiovascular calcification. An inflammatory disease

International Nuclear Information System (INIS)

New, S.E.P.; Aikawa, E.

2011-01-01

Cardiovascular calcification is an independent risk factor for cardiovascular morbidity and mortality. This disease of dysregulated metabolism is no longer viewed as a passive degenerative disease, but instead as an active process triggered by pro-inflammatory cues. Furthermore, a positive feedback loop of calcification and inflammation is hypothesized to drive disease progression in arterial calcification. Both calcific aortic valve disease and atherosclerotic arterial calcification may possess similar underlying mechanisms. Early histopathological studies first highlighted the contribution of inflammation to cardiovascular calcification by demonstrating the accumulation of macrophages and T lymphocytes in 'early' lesions within the aortic valves and arteries. A series of in vitro work followed, which gave a mechanistic insight into the stimulation of smooth muscle cells to undergo osteogenic differentiation and mineralization. The emergence of novel technology, in the form of animal models and more recently molecular imaging, has enabled accelerated progression of this field, by providing strong evidence regarding the concept of this disorder as an inflammatory disease. Although there are still gaps in our knowledge of the mechanisms behind this disorder, this review discusses the various studies that have helped form the concept of the inflammation-dependent cardiovascular calcification paradigm.

Diabetes Drugs and Cardiovascular Safety

Ji Cheol Bae

2016-06-01

Full Text Available Diabetes is a well-known risk factor of cardiovascular morbidity and mortality, and the beneficial effect of improved glycemic control on cardiovascular complications has been well established. However, the rosiglitazone experience aroused awareness of potential cardiovascular risk associated with diabetes drugs and prompted the U.S. Food and Drug Administration to issue new guidelines about cardiovascular risk. Through postmarketing cardiovascular safety trials, some drugs demonstrated cardiovascular benefits, while some antidiabetic drugs raised concern about a possible increased cardiovascular risk associated with drug use. With the development of new classes of drugs, treatment options became wider and the complexity of glycemic management in type 2 diabetes has increased. When choosing the appropriate treatment strategy for patients with type 2 diabetes at high cardiovascular risk, not only the glucose-lowering effects, but also overall benefits and risks for cardiovascular disease should be taken into consideration.

Age-related alterations of left ventricular (LV) structure and function that may predispose to cardiovascular events are not well understood. We used cardiac MRI to examine age-related differences in LV structure and function in 5004 participants without overt cardiovascular disease when enrolled in the Multi-Ethnic Study of Atherosclerosis; 1099 participants received additional strain analyses by MRI tagging. We also assessed the relation of age-associated remodeling with cardiovascular outcomes using Cox proportional hazard models adjusting for cardiovascular risk factors. Although LV mass decreased with age (-0.3 g per year), the mass-to-volume ratio markedly increased (+5 mg/mL per year, Pfall in stroke volume (-0.4 mL per year, P or =65 years; hazard ratio, 1.68 [CI 0.77 to 3.68]) individuals with the highest compared to lowest mass-to-volume ratio quintile (P(interaction)=0.013). Age is associated with a phenotype of LV remodeling marked by increased mass-to-volume ratio and accompanied by systolic as well as diastolic myocardial dysfunction that is not reflected by preserved ejection fraction. This pattern of ventricular remodeling confers significant cardiovascular risk, particularly when present earlier in life.

Although previous studies have analyzed the association between cardiovascular risk factors and blood pressure in adolescents, few studies conducted in developing countries analyzed whether the aggregation of risk factors contributes to an increased risk of high blood pressure in adolescents. The objective of this study was to assess the association between cardiovascular risk factors (including general overweight, abdominal obesity, high consumption of foods rich in fats, and insufficient physical activity levels) and high blood pressure in adolescents. This study was carried out from 2007 to 2008 with 1021 adolescents (528 girls) from primary schools located in the city of Londrina- Brazil. Blood pressure was assessed using an oscillometric device. General overweight was obtained through body mass index, abdominal obesity was assessed using waist circumference, and the consumption of foods rich in fat and physical activity were assessed using a questionnaire. The sum of these risk factors was determined. Adolescents with three or four aggregated risk factors were more likely to have higher values of systolic and diastolic blood pressure when compared with adolescents who did not have any cardiovascular risk factors (P = 0.001 for both). Logistic regression indicated that groups of adolescents with 2 (OR= 2.46 [1.11-5.42]; P = 0.026), 3 (OR= 4.97 [2.07-11.92]; P = 0.001) or 4 risk factors (OR= 6.79 [2.24-19.9]; P = 0.001) presented an increased likelihood of high blood pressure. The number of cardiovascular risk factors was found to be related to high blood pressure in adolescents. Copyright © 2014 Wiley Periodicals, Inc.

Full Text Available Nuts are often considered beneficial for health, yet few studies have examined determinants of their intake and the associations between nut consumption and various cardiovascular disease risk factors. The aim of this study was to identify factors associated with nut intake in a Mediterranean population, in Croatia, and to investigate the association of nut intake and various cardiovascular risk factors. Methods: Subjects from the Island of Vis, Island of Korčula and the City of Split were included in this cross-sectional study (n = 4416 in total; 4011 without known cardiovascular disease. Survey responses, medical records and clinically relevant measurements were utilized. Multivariate ordinal and logistic regression models were used in the analysis, adjusting for known confounding factors. Results: As low as 5% of all subjects reported daily, and 11% reported weekly, nut consumption. The characteristics associated with more frequent nut intake were female gender (Odds ratio (OR = 1.39; 95% confidence interval (CI 1.19–1.62, highest level of education (1.42; 1.15–1.76 and material status (1.58; 1.29–1.93, smoking abstinence (1.21; 1.04–1.42 in never-smokers and 1.22; 1.02–1.46 in ex-smokers, Mediterranean diet adherence (1.87; 1.62–2.15, and absence of central obesity (1.29; 1.09–1.53, absence of diabetes (1.30; 1.02–1.66 and metabolic syndrome (1.17; 1.01–1.36. Subjects who consumed nuts had more favorable waist-to-height (overall p = 0.036 and waist-to-hip ratios (0.033, lesser odds of elevated fibrinogen (p < 0.001 in both weekly and monthly nut consumers and reduced high-density lipoprotein (HDL cholesterol (p = 0.026, compared to non-consumers. Conclusions: It appears that frequent nut consumption is an integral part of a healthy lifestyle and better socioeconomic status. A beneficial association of nut intake with cardiovascular risk factors was confirmed in this study.

High blood pressure is an important risk factor for cardiovascular disease and cardiovascular events worldwide. Clinical and epidemiological studies suggest that cocoa-rich products reduce the risk of cardiovascular disease. According to this, cocoa has a high content in polyphenols, especially flavanols. Flavanols have been described to exert favorable effects on endothelium-derived vasodilation via the stimulation of nitric oxide-synthase, the increased availability of l-arginine, and the decreased degradation of NO. Cocoa may also have a beneficial effect by protecting against oxidative stress alterations and via decreased platelet aggregation, decreased lipid oxidation, and insulin resistance. These effects are associated with a decrease of blood pressure and a favorable trend toward a reduction in cardiovascular events and strokes. Previous meta-analyses have shown that cocoa-rich foods may reduce blood pressure. Long-term trials investigating the effect of cocoa products are needed to determine whether or not blood pressure is reduced on a chronic basis by daily ingestion of cocoa. Furthermore, long-term trials investigating the effect of cocoa on clinical outcomes are also needed to assess whether cocoa has an effect on cardiovascular events. A 3 mmHg systolic blood pressure reduction has been estimated to decrease the risk of cardiovascular and all-cause mortality. This paper summarizes new findings concerning cocoa effects on blood pressure and cardiovascular health, focusing on putative mechanisms of action and "nutraceutical " viewpoints.

Full Text Available Abstract Background Despite important improvements in available prevention and treatment, cardiovascular diseases (CVD remain an important cause of morbidity and mortality. Not all high-risk patients and patients with CVD have healthy lifestyles and receive the best possible healthcare. Internationally comparative data are needed to compare cardiovascular risk management in different countries, and to examine the impact of improvement programs and others factors. Objectives This study aims to provide internationally comparative data on cardiovascular risk management provided in primary care and on health-related lifestyles of patients in Europe. The study will also explore the views of doctors and patients on innovative preventive services for CVDs. Design and methods An observational cross-sectional study is planned. In 10 European countries, stratified samples of 36 practices per country will be recruited. In each practice, three samples of 15 patients each will be sampled: patients with coronary heart disease, patients at high risk for CVD, and healthy adult patients. The quality of cardiovascular risk management has been specified in terms of 44 performance indicators that resulted from an international Delphi-procedure with general practitioners. Most indicators are based on medical records, and some on a structured interview with a contact person of the practice. Lifestyle (smoking, physical exercise, diet will be measured with previously validated questionnaires that are completed by patients. Additional measures include practice characteristics and exposure to programs to improve cardiovascular care.

1981-07-01

The association between specific job characteristics and subsequent cardiovascular disease was tested using a large random sample of the male working Swedish population. The prospective development of coronary heart disease (CHD) symptoms and signs was analyzed using a multivariate logistic regression technique. Additionally, a case-controlled study was used to analyze all cardiovascular-cerebrovascular (CHD-CVD) deaths during a six-year follow-up. The indicator of CHD symptoms and signs was validated in a six-year prospective study of CHD deaths (standardized mortality ratio 5.0; p less than or equal to .001). A hectic and psychologically demanding job increases the risk of developing CHD symptoms and signs (standardized odds ratio 1.29, p less than 0.25) and premature CHD-CVD death (relative risk 4.0, p less than .01). Low decision latitude-expressed as low intellectual discretion and low personal schedule freedom-is also associated with increased risk of cardiovascular disease. Low intellectual discretion predicts the development of CHD symptoms and signs (SOR 1.44, p less than .01), while low personal schedule freedom among the majority of workers with the minimum statutory education increases the risk of CHD-CVD death (RR 6.6, p less than .0002). The associations exist after controlling for age, education, smoking, and overweight.

Although it is widely thought that childhood levels of cardiovascular (CV) risk factors are related to adult CV disease, longitudinal data directly linking the two are lacking. This paper describes the design and organization of the International Childhood Cardiovascular Cohort Consortium Outcomes Study (i3C Outcomes), the first longitudinal cohort study designed to locate adults with detailed, repeated, childhood biological, physical, and socioeconomic measurements and a harmonized database. I3C Outcomes uses a Heart Health Survey (HHS) to obtain information on adult CV endpoints, using mail, email, telephone, and clinic visits in the United States (U.S.) and Australia and a national health database in Finland. Microsoft Access, REsearch Data Capture (REDCap) (U.S.), LimeSurvey (Australia), and Medidata™ Rave data systems are used to collect, transfer and organize data. Self-reported CV events are adjudicated via hospital and doctor-released medical records. After the first two study years, participants (N = 10,968) were more likely to be female (56% vs. 48%), non-Hispanic white (90% vs. 80%), and older (10.4 ± 3.8 years vs. 9.4 ± 3.3 years) at their initial childhood study visit than the currently non-recruited cohort members. Over 48% of cohort members seen during both adulthood and childhood have been found and recruited, to date, vs. 5% of those not seen since childhood. Self-reported prevalences were 0.7% Type 1 Diabetes, 7.5% Type 2 Diabetes, 33% hypertension, and 12.8% CV event. 32% of CV events were judged to be true. I3C Outcomes is uniquely able to establish evidence-based guidelines for child health care and to clarify relations to adult CV disease. Copyright © 2018 Elsevier Inc. All rights reserved.

Full Text Available Occupational exposure to particulate air pollution has been associated with an increased risk of cardiovascular disease. However, the risk to welders working today remains unclear. We aimed to elucidate the cardiovascular effects of exposure to welding fumes.In a cross-sectional study, structured interviews and biological sampling were conducted for 101 welders and 127 controls (all non-smoking males from southern Sweden. Personal breathing zone sampling of respirable dust was performed. Blood pressure (BP and endothelial function (using peripheral arterial tonometry were measured. Plasma and serum samples were collected from peripheral blood for measurement of C-reactive protein, low-density lipoprotein, homocysteine, serum amyloid A, and cytokines.Welders were exposed to 10-fold higher levels of particles than controls. Welders had significantly higher BP compared to controls, an average of 5 mm Hg higher systolic and diastolic BP (P ≤ 0.001. IL-8 was 3.4 ng/L higher in welders (P=0.010. Years working as a welder were significantly associated with increased BP (β=0.35, 95%CI 0.13 - 0.58, P=0.0024 for systolic BP; β=0.32, 95%CI 0.16 - 0.48, P<0.001 for diastolic BP, adjusted for BMI but exposure to respirable dust was not associated with BP. No clear associations occurred between welding and endothelial function, or other effect markers.A modest increase in BP was found among welders compared to controls suggesting that low-to-moderate exposure to welding fumes remains a risk factor for cardiovascular disease.

The relevance of cardiovascular role played by levels of serum uric acid is dramatically growing, especially as cardiovascular risk factor potentially able to exert either a direct deleterious impact or a synergic effect with other cardiovascular risk factors. At the present time, it still remains undefined the threshold level of serum uric acid able to contribute to the cardiovascular risk. Indeed, the available epidemiological case studies are not homogeneous, and some preliminary data suggest that the so-called "cardiovascular threshold limit" may substantially differ from that identified as a cut-off able to trigger the acute gout attack. In such scenario, there is the necessity to clarify and quantify this threshold value, to insert it in the stratification of risk algorithm scores and, in turn, to adopt proper prevention and correction strategies. The clarification of the relationship between circulating levels of uric acid and cardio-nephro-metabolic disorders in a broad sample representative of general population is critical to identify the threshold value of serum uric acid better discriminating the increased risk associated with uric acid. The Uric acid Right for heArt Health (URRAH) project has been designed to define, as primary objective, the level of uricemia above which the independent risk of cardiovascular disease may increase in a significantly manner in a general Italian population.

Background Prevalence of diagnostic inertia (DI), defined as a failure to diagnose disease, has not been analysed in patients with obesity. Aim To quantify DI for cardiovascular risk factors (CVRF) in patients with obesity, and determine its association with the cardiovascular risk score. Design and setting Cross-sectional study of people ≥40 years attending a preventive programme in primary healthcare centres in Spain in 2003–2004. Method All patients with obesity attending during the first 6 months of the preventive programme were analysed. Participants had to be free of CVD (myocardial ischaemia or stroke) and aged 40–65 years; the criteria used to measure SCORE (Systematic COronary Risk Evaluation). Three subgroups of patients with obesity with no personal history of CVRF but with poor control of risk factors were established. Outcome variable was DI, defined as poor control of risk factors and no action taken by the physician. Secondary variables were diabetes, fasting blood glucose (FBG), body mass index (BMI), and SCORE. Adjusted odds ratios (OR) was determined using multivariate logistic regression models. Results Of 8687 patients with obesity in the programme, 6230 fulfilled SCORE criteria. Prevalence of DI in the three subgroups was: hypertension, 1275/1816 (70.2%) patients affected (95% CI = 68.1 to 72.3%); diabetes, 335/359 (93.3%) patients affected (95% CI = 90.7 to 95.9%); dyslipidaemia subgroup, 1796/3341 (53.8%) patients affected (95% CI = 52.1 to 55.4%. Factors associated with DI for each subgroup were: for hypertension, absence of diabetes, higher BMI, and greater cardiovascular risk; for dyslipidaemia, diabetes, higher BMI, and greater cardiovascular risk (SCORE); and for diabetes, lower FBG levels, lower BMI, and greater cardiovascular risk. Conclusion This study quantified DI in patients with obesity and determined that it was associated with a greater cardiovascular risk. PMID:26120135

Cardiovascular risk-benefit profile of sibutramine.

Science.gov (United States)

Scheen, A J

2010-01-01

Sibutramine is a combined norepinephrine and serotonin reuptake inhibitor used as an antiobesity agent to reduce appetite and promote weight loss in combination with diet and exercise. At a daily dose of 10-20 mg, it was initially considered to have a good safety profile, as it does not induce primary pulmonary hypertension or adverse effects on cardiac valves, in contrast to previous reports relating to some other antiobesity agents. However, it exerts disparate effects on cardiovascular risk factors. On the one hand, sibutramine may have antiatherogenic activities, as it improves insulin resistance, glucose metabolism, dyslipidemia, and inflammatory markers, with most of these effects resulting from weight loss rather than from an intrinsic effect of the drug. On the other hand, because of its specific mode of action, sibutramine exerts a peripheral sympathomimetic effect, which induces a moderate increase in heart rate and attenuates the reduction in BP attributable to weight loss or even slightly increases BP. It may also prolong the QT interval, an effect that could induce arrhythmias. Because of these complex effects, it is difficult to conclude what the final impact of sibutramine on cardiovascular outcomes might be. Sibutramine has been shown to exert favorable effects on some surrogate cardiovascular endpoints such as reduction of left ventricular hypertrophy and improvement of endothelial dysfunction. A good cardiovascular safety profile was demonstrated in numerous 1- to 2-year controlled trials, in both diabetic and nondiabetic well selected patients, as well as in several observational studies. However, since 2002, several cardiovascular adverse events (hypertension, tachycardia, arrhythmias, and myocardial infarction) have been reported in sibutramine-treated patients. This led to a contraindication of the use of this antiobesity agent in patients with established coronary heart disease, previous stroke, heart failure, or cardiac arrhythmias. SCOUT

Polycystic ovary syndrome (PCOS) is associated with higher prevalence of cardiovascular risk factors but the relative prevalence of cardiovascular disease in women with PCOS has not previously been reported. We have compared cardiovascular mortality and morbidity in middle-aged women previously diagnosed with PCOS and age-matched control women. A retrospective cohort study of women diagnosed with PCOS in the United Kingdom before 1979. Seventy cohort members died before 31 March 1999. Morbidity data were collected from 319 women with PCOS and 1060 age-matched control women. Sixty-one women with PCOS and 63 control women attended a clinical examination. Data were collected from death certificates, general practitioners' records and questionnaires with measurement of cardiovascular risk factors in a subsample of questionnaire respondents. All-cause and cardiovascular mortality in the cohort were similar to women in the general population (standardized mortality ratios (95% CI): 93 (72-117) and 78 (45-124), respectively). Women with PCOS had higher levels of several cardiovascular risk factors: diabetes (P = 0.002) hypertension (P = 0.04), hypercholesterolaemia (P heart disease (CHD) was not significantly more common in women with PCOS (crude OR (95%CI) 1.5 (0.7-2.9)) but the crude OR for cerebrovascular disease was 2.8 (1.1-7.1). At long-term follow-up, a history of nonfatal cerebrovascular disease and cardiovascular risk factors including diabetes are more prevalent among women with polycystic ovary syndrome. Morbidity and mortality from of coronary heart disease among women with polycystic ovary syndrome is not as high as previously predicted. This finding challenges our understanding of the aetiology of coronary heart disease in women.

No studies have compared first cardiovascular disease (CVD) events and non-CVD death between races in a competing risks framework, which examines risks for numerous events simultaneously. We used competing Cox models to estimate hazards for first CVD events and non-CVD death within and between races in 3 multicenter, National Heart, Lung, and Blood Institute-sponsored cohorts. Of 14 569 Atherosclerosis Risk in Communities (ARIC) study participants aged 45 to 64 years with mean follow-up of 10.5 years, 11.6% had CVD and 5.0% had non-CVD death as first events; among 4237 Cardiovascular Health Study (CHS) study participants aged 65 to 84 years and followed for 8.5 years, these figures were 43.2% and 15.7%, respectively. Middle-aged blacks were significantly more likely than whites to experience any CVD as a first event; this disparity disappeared by older adulthood and after adjustment for CVD risk factors. The pattern of results was similar for Multi-Ethnic Study of Atherosclerosis (MESA) participants. Traditional Cox and competing risks models yielded different results for coronary heart disease risk. Black men appeared somewhat more likely than white men to experience coronary heart disease with use of a standard Cox model (hazard ratio 1.06; 95% CI 0.90, 1.26), whereas they appeared less likely than white men to have a first coronary heart disease event with use of a competing risks model (hazard ratio, 0.77; 95% CI, 0.60, 1.00). CVD affects blacks at an earlier age than whites; this may be attributable in part to elevated CVD risk factor levels among blacks. Racial disparities in first CVD incidence disappear by older adulthood. Competing risks analyses may yield somewhat different results than traditional Cox models and provide a complementary approach to examining risks for first CVD events.

Post-traumatic stress disorder and cardiovascular disease.

Edmondson, Donald; von Känel, Roland

2017-04-01

In this paper, a first in a Series of two, we look at the evidence for an association of post-traumatic stress disorder with incident cardiovascular disease risk and the mechanisms that might cause this association, as well as the prevalence of post-traumatic stress disorder due to cardiovascular disease events and its associated prognostic risk. We discuss research done after the publication of previous relevant systematic reviews, and survey currently funded research from the two most active funders in the field: the National Institutes of Health and the US Veterans Administration. We conclude that post-traumatic stress disorder is a risk factor for incident cardiovascular disease, and a common psychiatric consequence of cardiovascular disease events that might worsen the prognosis of the cardiovascular disease. There are many candidate mechanisms for the link between post-traumatic stress disorder and cardiovascular disease, and several ongoing studies could soon point to the most important behavioural and physiological mechanisms to target in early phase intervention development. Similarly, targets are emerging for individual and environmental interventions that might offset the risk of post-traumatic stress disorder after cardiovascular disease events.

Intensive glycemic control and cardiovascular disease: an update.

Brown, Aparna; Reynolds, L Raymond; Bruemmer, Dennis

2010-07-01

Cardiovascular complications constitute the major cause of morbidity and mortality in patients with diabetes. The Diabetes Control and Complications Trial (DCCT) and the United Kingdom Prospective Diabetes Study (UKPDS) provided consistent evidence that intensive glycemic control prevents the development and progression of microvascular complications in patients with type 1 or type 2 diabetes. However, whether intensive glucose lowering also prevents macrovascular disease and major cardiovascular events remains unclear. Extended follow-up of participants in these studies demonstrated that intensive glycemic control reduced the long-term incidence of myocardial infarction and death from cardiovascular disease. By contrast, the Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial, Action in Diabetes and Vascular Disease: Preterax and Diamicron Modified Release Controlled Evaluation (ADVANCE) trial, and Veterans Affairs Diabetes Trial (VADT) results suggested that intensive glycemic control to near normoglycemia had either no, or potentially even a detrimental, effect on cardiovascular outcomes. This article discusses the effects of intensive glycemic control on cardiovascular disease, and examines key differences in the design of these trials that might have contributed to their disparate findings. Recommendations from the current joint ADA, AHA, and ACCF position statement on intensive glycemic control and prevention of cardiovascular disease are highlighted.

Preeclampsia, prematurity and cardiovascular health in adult life.

Lewandowski, Adam J; Leeson, Paul

2014-11-01

Investigations into how perinatal growth and intrauterine environment may 'programme' risk of later cardiovascular disease have been ongoing for over two decades. One of the more recent outcomes of these studies is the observation that certain pregnancy-related conditions, such as preterm birth, have an unusually large impact on the long-term cardiovascular health of the offspring. In the present paper, we review the current literature of how preterm birth affects the long-term cardiovascular structure and function of the offspring, considering three major areas of investigation: firstly, outlining the long-term cardiovascular phenotypic changes in preterm-born individuals; secondly, investigating factors related to preterm birth that may be modifying cardiovascular phenotype, such as preeclampsia, perinatal interventions, and physiological disturbances; and thirdly, the expected clinical relevance of these cardiovascular changes. This review discusses the importance of continued research focused on the mechanistic understanding of these cardiovascular alterations in order to develop specific primary prevention strategies.

Full Text Available Background and Objectives: Chronic diseases are among the most important causes of mortality. The aim of the current study was to compare the Brain/behavioral systems and Dark personality traits of Machiavellianism, narcissism, and psychopathy in cancer, cardiovascular female patients and normal women. Methods: In this study, 60 individuals were selected using available sampling in three groups of 20 cancer patients, cardiovascular patients, and normal subjects. Finally, in order to test the goals and hypotheses of the research, the participants were studied based on Behavioral Activation System and Behavioral Inhibition System, and Dark Triad traits. Data analysis was performed using multivariate ANOVA, univariate ANOVA and post-hoc tests. Results: In this study, there was a significant difference among the three groups in Brain/behavioral systems and traits of Machiavellianism, narcissism, and psychopathy, so that the cancer and cardiovascular patients had higher score in dark triad traits compared to normal individuals. Also, the cancer patients had a higher score in Machiavellianism trait compared to the cardiovascular patients. In the brain/behavioral systems, cardiovascular and cancer patients had higher score in behavioral inhibition system (BIS component compared to the normal individuals in the of behavioral inhibition system (BIS. Also, in the reward seeking subscale of behavioral activation system (BAS-f, cancer patients had a higher score compared to cardiovascular patients, which was significantly different.

The PreFord Study is a multicenter prospective cohort study to evaluate guideline based risk management on primary prevention of cardiovascular diseases. Furthermore a randomised controlled trial (RCT) will be designed to analyse the effect of a special intervention program. 40,000 employees of the Ford Motor Company, Visteon Company and Deutz Company in Germany will be included, monitored for ten years and the following primary endpoints will be investigated: 1. evaluation and comparison of established and newly developed risk-scores, 2. the relative impact of single and combined cardiovascular risk factors on cardiovascular diseases, 3. the influence of a novel occupationally integrated ambulant rehabilitation program in combination with a guideline oriented optimal drug therapy within a high risk group on the primary endpoint: risk reduction by, 4. the influence of this intervention on secondary endpoints: death, myocardial infarction and stroke, combined appearance of angina pectoris and hospitalisation, occurrence of cerebral circulatory disorder and hospitalisation, occurrence of peripheral occlusive arterial disease and hospitalisation and single cardiovascular risk factors and cost-benefit-analysis. Beginning with an cross sectional study there will be a systemic screening of cardiovascular risk profiles, of anthropometric data and different lifestyle-factors. Based on these data participants will be differentiated into three risk-groups according to the risk score of the European Society of Cardiology (risk of a lethal primary acute cardiovascular event: I 1- or = 5%). In the following longitudinal study different strategies will be applied: Group I: low risk ( 1.5% per year or >15% within the next 10 years) will be randomised into two interventional groups. The first one, the intervention-group "PreFord" will perform an occupational integrated rehabilitation program (2,5-3 hours twice a week, for 15 weeks according to the BAR guidelines) with a following

Cardiovascular disease remains the leading cause of death in the USA. Social networks have a positive association with obesity, smoking cessation and weight loss. This article summarizes studies evaluating the impact of social networks on the management of cardiovascular disease. The 35 studies included in the article describe the impact of social networks on a decreased incidence of cardiovascular disease, depression and mortality. In addition, having a large-sized social network is also associated with better outcomes and improved health. The role of pharmacists is beginning to play an important role in the patient-centered medical home, which needs to be incorporated into social networks. The patient-centered medical home can serve as an adaptive source for social network evolvement.

Cardiovascular Disease, Mitochondria, and Traditional Chinese Medicine

Full Text Available Recent studies demonstrated that mitochondria play an important role in the cardiovascular system and mutations of mitochondrial DNA affect coronary artery disease, resulting in hypertension, atherosclerosis, and cardiomyopathy. Traditional Chinese medicine (TCM has been used for thousands of years to treat cardiovascular disease, but it is not yet clear how TCM affects mitochondrial function. By reviewing the interactions between the cardiovascular system, mitochondrial DNA, and TCM, we show that cardiovascular disease is negatively affected by mutations in mitochondrial DNA and that TCM can be used to treat cardiovascular disease by regulating the structure and function of mitochondria via increases in mitochondrial electron transport and oxidative phosphorylation, modulation of mitochondrial-mediated apoptosis, and decreases in mitochondrial ROS. However further research is still required to identify the mechanism by which TCM affects CVD and modifies mitochondrial DNA.

Research of cardiac involvement in patients with rheumatoid arthritis can prevent complications and place in a logical secondary prevention. The objective of this study was to investigate the echocardiographic parameters in a population of Senegalese patients with rheumatoid arthritis without clinically evident cardiovascular manifestations. We conducted a descriptive cross-sectional study, which included prospectively from outpatients in the internal medicine department of university hospital center Aristide Le Dantec in Dakar, Senegal, with a diagnosis of rheumatoid arthritis without clinically evident cardiovascular disease. It focused on a sample of 73 patients of both sexes aged at least 18 years. Following clinical examination, we conducted laboratory tests (CRP, fibrinogen, ESR, rheumatoid factors: Latex and Waaler-Rose, anti-CCP, antinuclear factors and anti-ENA antibodies), ECG, echocardiography standard. Data were analyzed using a descriptive study of the different variables with the calculation of proportions for categorical variables, and the positional parameters and dispersion for quantitative variables. A total of 73 patients with rheumatoid arthritis without obvious cardiac events and meeting the criteria of definition of the ACR 1987 were included in the study. The mean age was 44.17±14.43 years with extremes of 18 and 75 years. The mean duration of RA was 5.93±4.78 years. The concept of family inflammatory arthritis was reported in 35.60% of cases and almost one in six patients had at least a factor of cardiovascular risk (16.96%). The abnormalities found in Doppler echocardiography were dominated by diastolic LV dysfunction (42.46%), increased left ventricular mass in 35.61%. Valvular leaks of variable grades were highlighted regarding all orifices but were rarely significant. The realization of echocardiography in patients with rheumatoid arthritis without clinically evident cardiovascular manifestations helps to highlight cardiovascular

An increased interarm systolic blood pressure difference is an easily determined physical examination finding. The relationship between interarm systolic blood pressure difference and risk of future cardiovascular disease is uncertain. We described the prevalence and risk factor correlates of interarm systolic blood pressure difference in the Framingham Heart Study (FHS) original and offspring cohorts and examined the association between interarm systolic blood pressure difference and incident cardiovascular disease and all-cause mortality. An increased interarm systolic blood pressure difference was defined as ≥ 10 mm Hg using the average of initial and repeat blood pressure measurements obtained in both arms. Participants were followed through 2010 for incident cardiovascular disease events. Multivariable Cox proportional hazards regression analyses were performed to investigate the effect of interarm systolic blood pressure difference on incident cardiovascular disease. We examined 3390 (56.3% female) participants aged 40 years and older, free of cardiovascular disease at baseline, mean age of 61.1 years, who attended a FHS examination between 1991 and 1994 (original cohort) and from 1995 to 1998 (offspring cohort). The mean absolute interarm systolic blood pressure difference was 4.6 mm Hg (range 0-78). Increased interarm systolic blood pressure difference was present in 317 (9.4%) participants. The median follow-up time was 13.3 years, during which time 598 participants (17.6%) experienced a first cardiovascular event, including 83 (26.2%) participants with interarm systolic blood pressure difference ≥ 10 mm Hg. Compared with those with normal interarm systolic blood pressure difference, participants with an elevated interarm systolic blood pressure difference were older (63.0 years vs 60.9 years), had a greater prevalence of diabetes mellitus (13.3% vs 7.5%,), higher systolic blood pressure (136.3 mm Hg vs 129.3 mm Hg), and a higher total cholesterol

HIV INFECTION, ANTIRETROVIRAL THERAPY AND CARDIOVASCULAR RISK

Full Text Available In the last 15 years, highly active antiretroviral therapy (HAART has determined a dramatic reduction of both morbidity and mortality in human immunodeficiency virus (HIV-infected subjects, transforming this infection in a chronic and manageable disease. Patients surviving with HIV in the developed world, in larger number men,  are becoming aged. As it would be expected for a population of comparable age, many HIV-infected individuals report a family history of cardiovascular disease, a small proportion have already experienced a cardiovascular event and an increasing proportion has diabetes mellitus. Smoking rate is very high while an increasing proportion of HIV-infected individuals have dyslipidaemia. Studies suggest that these traditional risk factors could play an important  role in the development of cardiovascular disease in these patients as they do in the general population. Thus, whilst the predicted 10-year cardiovascular disease risk remains relatively low at present, it will likely increase in relation to the progressive aging of  this patient population. Thus, the long-term follow-up of HIV infected patients has to include co-morbidity management such as cardiovascular disease prevention and treatment. Two intriguing aspects related to the cardiovascular risk in patients with HIV infection are the matter of current investigation: 1 while these subjects share many cardiovascular risk factors with the general population, HIV infection itself increases cardiovascular risk; 2 some HAART regimens too influence atherosclerotic profile, partly due to lipid changes. Although the mechanisms involved in the development of cardiovascular complications in HIV-infected patients remain to be fully elucidated, treatment guidelines recommending interventions to prevent cardiovascular disease in these individuals are already available; however, their application is still limited.

Currently, cardiovascular risk factors have not been studied so extensively in young people. To compare the cardiovascular risk factor between Colombian and Mexican children. This was a transversal, descriptive, comparative and clinical study. 30 children of primary school aged 6-12 from Bogotá, Colombia were matched by age with a sample of 30 children from Toluca, Mexico. Cardiovascular risk factors measured were Body Mass Index (BMI), serum lipid profile, glucose and homocystein (Hcy). Besides we applied the validated surveys formats for food (dietary history), physical activity (International Physical Activity Questionnaire, IPAQ), alcohol consumption and smoking. BMI was higher in Mexican children than in Colombian (20.43±3.35 vs 16.92±3.46) (p≤0.001). Among Mexican children, 20% (6) of them had blood glucose concentration greater than 100 mg/dl, 6.6% (2) had triglycerides greater than 200 mg/dl, 36.6% (11) had cholesterol levels greater than 170 mg/dl, 16% (53.3) had HDL lower than the recommended limits, and 60% (18) had LDL above the normal limit. For the Colombian population these percentages were of 0, 3.3, 46.6, 13.33 and 53.3 respectively. Mexican children had a stronger correlation between BMI and atherogenic indices and less physical activity than Colombian. Of the 30 Mexican children enrolled in the study only 13% had none of the cardiovascular risk factors, while in the Colombian this percentage was of 33. Latin American children are not metabolically homogeneous, Mexican children are at high risk of cardiovascular disease.

Full Text Available Background: Nutritional studies focus on traditional cultural models and lifestyles in different countries. The aim of this study was to examine the adherence to the Mediterranean diet, life habits, and risk factors associated with cardiovascular diseases among people living in different geographical regions in Spain. Methods: A descriptive cross-sectional study was conducted in each region. The sampling scheme consisted of a random three-stage stratified sampling program according to geographic region, age, and gender. A total of 1732 subjects were asked to complete a questionnaire designed to assess their nutrient intake, dietary habits, and exercise. A diet score that assesses the adherence of participants to the Mediterranean diet (range 0–10 was also applied. Results: Southeastern Spain had the lowest score for adherence to the Mediterranean diet because of the low consumption of fish and plant products. A lower adherence score to the Mediterranean diet was strongly associated with the prevalence of hypertension (p = 0.018. Conclusions: A low level of adherence to the Mediterranean diet is accompanied by a high prevalence of hypertension and, therefore, a raised cardiovascular risk in the country. The adherence score could help identify individuals at greater cardiovascular risk.

Full Text Available Epidemiological studies have shown that vegetable consumption is inversely related to the risk of cardiovascular diseases. Moreover, research has indicated that many vegetables like potatoes, soybeans, sesame, tomatoes, dioscorea, onions, celery, broccoli, lettuce and asparagus showed great potential in preventing and treating cardiovascular diseases, and vitamins, essential elements, dietary fibers, botanic proteins and phytochemicals were bioactive components. The cardioprotective effects of vegetables might involve antioxidation; anti-inflammation; anti-platelet; regulating blood pressure, blood glucose, and lipid profile; attenuating myocardial damage; and modulating relevant enzyme activities, gene expression, and signaling pathways as well as some other biomarkers associated to cardiovascular diseases. In addition, several vegetables and their bioactive components have been proven to protect against cardiovascular diseases in clinical trials. In this review, we analyze and summarize the effects of vegetables on cardiovascular diseases based on epidemiological studies, experimental research, and clinical trials, which are significant to the application of vegetables in prevention and treatment of cardiovascular diseases.

Greenberg, Jeffrey D; Furer, Victoria; Farkouh, Michael E

2011-11-15

Cardiovascular disease represents a major source of extra-articular comorbidity in patients with rheumatoid arthritis (RA). A combination of traditional cardiovascular risk factors and RA-related factors accounts for the excess risk in RA. Among RA-related factors, chronic systemic inflammation has been implicated in the pathogenesis and progression of atherosclerosis. A growing body of evidence--mainly derived from observational databases and registries--suggests that specific RA therapies, including methotrexate and anti-TNF biologic agents, can reduce the risk of future cardiovascular events in patients with RA. The cardiovascular profile of other biologic therapies for the treatment of RA has not been adequately studied, including of investigational drugs that improve systemic inflammation but alter traditional cardiovascular risk factors. In the absence of large clinical trials adequately powered to detect differences in cardiovascular events between biologic drugs in RA, deriving firm conclusions on cardiovascular safety is challenging. Nevertheless, observational research using large registries has emerged as a promising approach to study the cardiovascular risk of emerging RA biologic therapies.

Full Text Available Purpose: There is abundant evidence that neighborhood characteristics are significantly linked to the health of the inhabitants of a given space within a given time frame. This study is to statistically validate a web-based GIS application designed to support cardiovascular-related research developed by the NIH funded Research Centers in Minority Institutions (RCMI Translational Research Network (RTRN Data Coordinating Center (DCC and discuss its applicability to cardiovascular studies. Methods: Geo-referencing, geocoding and geospatial analyses were conducted for 500 randomly selected home addresses in a U.S. southeastern Metropolitan area. The correlation coefficient, factor analysis and Cronbach’s alpha (α were estimated to quantify measures of the internal consistency, reliability and construct/criterion/discriminant validity of the cardiovascular-related geospatial variables (walk score, number of hospitals, fast food restaurants, parks and sidewalks. Results: Cronbach’s α for CVD GEOSPATIAL variables was 95.5%, implying successful internal consistency. Walk scores were significantly correlated with number of hospitals (r = 0.715; p < 0.0001, fast food restaurants (r = 0.729; p < 0.0001, parks (r = 0.773; p < 0.0001 and sidewalks (r = 0.648; p < 0.0001 within a mile from homes. It was also significantly associated with diversity index (r = 0.138, p = 0.0023, median household incomes (r = −0.181; p < 0.0001, and owner occupied rates (r = −0.440; p < 0.0001. However, its non-significant correlation was found with median age, vulnerability, unemployment rate, labor force, and population growth rate. Conclusion: Our data demonstrates that geospatial data generated by the web-based application were internally consistent and demonstrated satisfactory validity. Therefore, the GIS application may be useful to apply to cardiovascular-related studies aimed to investigate potential impact of geospatial factors on diseases and/or the long

2011-12-01

Full Text Available Abstract Background Cardiovascular disease remains the primary cause of death worldwide. In the US, deaths due to cardiovascular disease for women exceed those of men. While cultural and psychosocial factors such as education, economic status, marital status and access to healthcare contribute to sex differences in adverse outcomes, physiological and molecular bases of differences between women and men that contribute to development of cardiovascular disease and response to therapy remain underexplored. Methods This article describes concepts, methods and procedures to assist in the design of animal and tissue/cell based studies of sex differences in cardiovascular structure, function and models of disease. Results To address knowledge gaps, study designs must incorporate appropriate experimental material including species/strain characteristics, sex and hormonal status. Determining whether a sex difference exists in a trait must take into account the reproductive status and history of the animal including those used for tissue (cell harvest, such as the presence of gonadal steroids at the time of testing, during development or number of pregnancies. When selecting the type of experimental animal, additional consideration should be given to diet requirements (soy or plant based influencing consumption of phytoestrogen, lifespan, frequency of estrous cycle in females, and ability to investigate developmental or environmental components of disease modulation. Stress imposed by disruption of sleep/wake cycles, patterns of social interaction (or degree of social isolation, or handling may influence adrenal hormones that interact with pathways activated by the sex steroid hormones. Care must be given to selection of hormonal treatment and route of administration. Conclusions Accounting for sex in the design and interpretation of studies including pharmacological effects of drugs is essential to increase the foundation of basic knowledge upon which to

Aspirin therapy is the clinical gold standard for the prevention of cardiovascular events. However, cardiovascular events still develop in some patients undergoing aspirin therapy. Many laboratory methods exist for measuring aspirin resistance. Using the platelet Function Analyzer (PFA)-100 system, we aimed to determine the effect of aspirin resistance on hospitalized cardiovascular events (hCVE) in a 5-year follow-up cohort. We also sought to determine the impact of aspirin resistance on the relationship between common cardiovascular risk factors and cardiovascular hospitalization. Aspirin resistance was evaluated in aspirin-treated patients from the outpatient department. A total of 465 patients during a 5-year follow-up period were included in this study. The primary endpoint of the study was hospitalization for any acute cardiovascular event. The prevalence and associated risk factors of acute cardiovascular events were evaluated. Aspirin resistance was prevalent in 91 (20.0%) of 465 patients. Prior hospitalization history of cardiovascular events was highly associated with aspirin resistance (P = .001). At the 5-year follow-up, cardiovascular events were found to have developed in 11 patients (8 stroke and 3 myocardial infarction) who exhibited aspirin resistance (12.1%) and in 9 (4 stroke and 5 myocardial infarction) patients who did not exhibit aspirin resistance (2.4%) (P resistance and cardiovascular events (adjusted odds ratio 4.28; 95% CI: 1.64-11.20; P = .03). PFA-100 measurements of aspirin resistance correlate with hCVE, as evidenced by both the past medical history and the 5-year follow-up. The logistic regression analysis results showed that aspirin resistance plays a larger role in hospitalized cardiovascular disease than do other cardiovascular risk factors. © 2017 John Wiley & Sons Ltd.

BACKGROUND : Canagliflozin is a sodium glucose cotransporter 2 inhibitor that reduces the risk of cardiovascular events. We report the effects on heart failure and cardiovascular death overall, in those with and without a baseline history of heart failure, and in other participant subgroups. METHODS : The CANVAS Program (Canagliflozin Cardiovascular Assessment Study) enrolled 10 142 participants with type 2 diabetes mellitus and high cardiovascular risk. Participants were randomly assigned to canagliflozin or placebo and followed for a mean of 188 weeks. The primary end point for these analyses was adjudicated cardiovascular death or hospitalized heart failure. RESULTS : Participants with a history of heart failure at baseline (14.4%) were more frequently women, white, and hypertensive and had a history of prior cardiovascular disease (all P failure was reduced in those treated with canagliflozin compared with placebo (16.3 versus 20.8 per 1000 patient-years; hazard ratio [HR], 0.78; 95% confidence interval [CI], 0.67-0.91), as was fatal or hospitalized heart failure (HR, 0.70; 95% CI, 0.55-0.89) and hospitalized heart failure alone (HR, 0.67; 95% CI, 0.52-0.87). The benefit on cardiovascular death or hospitalized heart failure may be greater in patients with a prior history of heart failure (HR, 0.61; 95% CI, 0.46-0.80) compared with those without heart failure at baseline (HR, 0.87; 95% CI, 0.72-1.06; P interaction =0.021). The effects of canagliflozin compared with placebo on other cardiovascular outcomes and key safety outcomes were similar in participants with and without heart failure at baseline (all interaction P values >0.130), except for a possibly reduced absolute rate of events attributable to osmotic diuresis among those with a prior history of heart failure ( P =0.03). CONCLUSIONS : In patients with type 2 diabetes mellitus and an elevated risk of cardiovascular disease, canagliflozin reduced the risk of cardiovascular death or hospitalized heart

Studies have shown that long-term exposure to air pollution such as fine particulate matter (≤2.5 μm in aerodynamic diameter [PM 2.5 ]) increases the risk of all-cause and cardiovascular mortality. To date, however, there are limited data on the impact of air pollution on specific cardiovascular diseases. This study aimed to evaluate cardiovascular effects of long-term exposure to air pollution among residents of Seoul, Korea. Healthy participants with no previous history of cardiovascular disease were evaluated between 2007 and 2013. Exposure to air pollutants was estimated by linking the location of outdoor monitors to the ZIP code of each participant's residence. Crude and adjusted analyses were performed using Cox regression models to evaluate the risk for composite cardiovascular events including cardiovascular mortality, acute myocardial infarction, congestive heart failure, and stroke. A total of 136 094 participants were followed for a median of 7.0 years (900 845 person-years). The risk of major cardiovascular events increased with higher mean concentrations of PM 2.5 in a linear relationship, with a hazard ratio of 1.36 (95% confidence interval, 1.29-1.43) per 1 μg/m 3 PM 2.5 . Other pollutants including PM 2.5-10 of CO, SO 2 , and NO 2 , but not O 3 , were significantly associated with increased risk of cardiovascular events. The burden from air pollution was comparable to that from hypertension and diabetes mellitus. This large-scale population-based study demonstrated that long-term exposure to air pollution including PM 2.5 increases the risk of major cardiovascular disease and mortality. Air pollution should be considered an important modifiable environmental cardiovascular risk factor. © 2017 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley.

Social capital is considered to be an important determinant of life expectancy and cardiovascular health. Evidence on the association between social capital and all-cause mortality, cardiovascular disease (CVD) and cancer was systematically reviewed. Prospective studies examining the association of social capital with these outcomes were systematically sought in Medline, Embase and PsycInfo, all from inception to 8 October 2012. We categorized the findings from studies according to seven dimensions of social capital, including social participation, social network, civic participation,social support, trust, norm of reciprocity and sense of community, and pooled the estimates across studies to obtain summary relative risks of the health outcomes for each social capital dimension. We excluded studies focusing on children, refugees or immigrants and studies conducted in the former Soviet Union. Fourteen prospective studies were identified. The pooled estimates showed no association between most social capital dimensions and all-cause mortality, CVD or cancer. Limited evidence was found for association of increased mortality with social participation and civic participation when comparing the most extreme risk comparisons. Evidence to support an association between social capital and health outcomes is limited. Lack of consensus on measurements for social capital hinders the comparability of studies and weakens the evidence base.

Diabetes is a serious health problem affecting approximately 29.1 million individuals in the United States. Another 86 million have prediabetes. The development and implementation of lifestyle modifications such as physical activity for these persons are among the most effective methods for prevention and treatment. The aim of this study was to examine relationships between glycemic control (HbA1c) and cardiovascular fitness (peak maximal oxygen uptake [VO 2 peak] and ventilatory threshold [VT]) in overweight/obese subjects with and without type 2 diabetes (T2DM). In addition, the influences of body mass index (BMI) and insulin sensitivity (homeostasis model assessment [HOMA %S]) on the relationship between glycemic control and cardiovascular fitness were explored. Data were abstracted from a completed study that included 51 overweight or obese subjects with T2DM ( n = 18), impaired glucose tolerance ( n = 8), or normal glucose tolerance ( n = 25). Relationships between glycemic control (HbA1c) and cardiovascular fitness (VO 2 peak and VT) were determined using correlational analysis and multiple linear regression analyses. A statistically significant relationship was observed between HbA1c and cardiovascular fitness. However, BMI and HOMA %S did not influence the relationship between glycemic control and cardiovascular fitness. HbA1c contributes to VO 2 peak and VT in obese and overweight subjects across glucose tolerance categories. Significant results were achieved despite the fact that there was a limited range of HbA1c based on the study inclusion criteria. This finding suggests that even a mild decrease in glycemic control can negatively influence cardiovascular fitness.

Toxic urban waste's assault on cardiovascular risk

Full Text Available A cardiovascular health survey of 1203 persons in households located near the hazardous waste disposal sites and in a reference community, was conducted from 2009 until today to assess whether rates of adverse cardiovascular health outcomes were elevated among persons living near the sites. Data included medical records of reported cardiovascular disease certificates and hospital admission for cardiovascular diseases from hospital database. The study areas appeared similar with respect to mortality, cancer incidence, and pregnancy outcomes. In contrast, rate ratios were greater than 1.5 for 2 of 19 reported diseases, i.e., angina pectoris, and strokes. The apparent broad-based elevation in reported diseases and symptoms may reflect increased perception or recall of conditions by respondents living near the sites. Our study found that cardiovascular risk is associated only with PM2.5 concentrations, derived from uncontrolled burning of municipal solid waste in particular sites of our country. Their analysis demonstrated a relationship between increased levels of eventual fine particulate pollution and higher rates of death and complications from cardiovascular and cerebrovascular diseases. Management of solid waste releases a number of toxic substances, most in small quantities and at extremely low levels. Because of the wide range of pollutants, the different pathways of exposure, long-term low-level exposure, and the potential for synergism among the pollutants, concerns remain about potential health effects but there are many uncertainties involved in the assessment. Future community-based health studies should include medical and psychosocial assessment instruments sufficient to distinguish between changes in health status and effects of resident reporting tendency.

Obstructive sleep apnea (OSA) during REM sleep is a common disorder. Data on whether OSA that occurs predominantly during REM sleep is associated with health outcomes are limited. The present study examined the association between OSA during REM sleep and a composite cardiovascular endpoint in a community sample with and without prevalent cardiovascular disease. Full-montage home polysomnography was conducted as part of the Sleep Heart Health Study. The study cohort was followed for an average of 9.5 years, during which time cardiovascular events were assessed. Only participants with a non-REM apnea-hypopnea index (AHI) of less than 5 events/h were included. A composite cardiovascular endpoint was determined as the occurrence of nonfatal or fatal events, including myocardial infarction, coronary artery revascularization, congestive heart failure, and stroke. Proportional hazards regression was used to derive the adjusted hazards ratios for the composite cardiovascular endpoint. The sample consisted of 3,265 subjects with a non-REM AHI of less than 5.0 events/h. Using a REM AHI of less than 5.0 events/h as the reference group (n = 1,758), the adjusted hazards ratios for the composite cardiovascular endpoint in those with severe REM OSA (≥30 events/h; n = 180) was 1.35 (95% confidence interval, 0.98-1.85). Stratified analyses demonstrated that the association was most notable in those with prevalent cardiovascular disease and severe OSA during REM sleep with an adjusted hazards ratio of 2.56 (95% confidence interval, 1.46-4.47). Severe OSA that occurs primarily during REM sleep is associated with higher incidence of a composite cardiovascular endpoint, but in only those with prevalent cardiovascular disease.

Congenital diaphragmatic hernia is associated with cardiovascular malformation. Many prognostic factors have been identified for isolated congenital diaphragmatic hernia; however, reports of concurrent congenital diaphragmatic hernia and cardiovascular malformation in infants are limited. This study evaluated congenital diaphragmatic hernia associated with cardiovascular malformation in infants. Factors associated with prognosis for patients were also identified. This retrospective cohort study was based on a Japanese survey of congenital diaphragmatic hernia patients between 2006 and 2010. Frequency and outcome of cardiovascular malformation among infants with congenital diaphragmatic hernia were examined. Severity of congenital diaphragmatic hernia and cardiovascular malformation were compared as predictors of mortality and morbidity. Cardiovascular malformation was identified in 76 (12.3%) of 614 infants with congenital diaphragmatic hernia. Mild cardiovascular malformation was detected in 19 (33.9%) and severe cardiovascular malformation in 37 (66.1%). Their overall survival rate at discharge was 46.4%, and the survival rate without morbidity was 23.2%. Mortality and morbidity at discharge were more strongly associated with severity of cardiovascular malformation (adjusted OR 7.69, 95%CI 1.96-30.27; adjusted OR 7.93, 95%CI 1.76-35.79, respectively) than with severity of congenital diaphragmatic hernia. The prognosis for infants with both congenital diaphragmatic hernia and cardiovascular malformation remains poor. Severity of cardiovascular malformation is a more important predictive factor for mortality and morbidity than severity of congenital diaphragmatic hernia. © 2013 The Authors.

Full Text Available Abstract Background Germline mutations of BRCA1/2 are associated with hereditary breast and ovarian cancer. Recent data suggests excess mortality in mutation carriers beyond that conferred by neoplasia, and recent in vivo and in vitro studies suggest a modulatory role for BRCA proteins in endothelial and cardiomyocyte function. We therefore tested the association of BRCA2 variants with clinical cardiovascular disease (CVD. Methods Using data from 1,170 individuals included in two multi-ethnic population-based studies (SHARE and SHARE-AP, the association between BRCA2 variants and CVD was evaluated. 15 SNPs in BRCA2 with minor allele frequencies (MAF > 0.01 had been previously genotyped using the cardiovascular gene-centric 50 k SNP array. 115 individuals (9.8% reported a CVD event, defined as myocardial infarction (MI, angina, silent MI, stroke, and angioplasty or coronary artery bypass surgery. Analyses were adjusted for age and sex. The SNPs rs11571836 and rs1799943 were subsequently genotyped using the MassARRAY platform in 1,045 cases of incident MI and 1,135 controls from the South Asian subset of an international case-control study of acute MI (INTERHEART, and rs11571836 was imputed in 4,686 cases and 4500 controls from the Pakistan Risk of Myocardial Infarction Study (PROMIS. Results Two BRCA2 SNPs, rs11571836 and rs1799943, both located in untranslated regions, were associated with lower risk of CVD (OR 0.47 p = 0.01 and OR 0.56 p = 0.03 respectively in the SHARE studies. Analysis by specific ethnicities demonstrated an association with CVD for both SNPs in Aboriginal People, and for rs11571836 only in South Asians. No association was observed in the European and Chinese subgroups. A non-significant trend towards an association between rs11571836 and lower risk of MI was observed in South Asians from INTERHEART [OR = 0.87 (95% CI: 0.75-1.01 p = 0.068], but was not evident in PROMIS [OR = 0.96 (95% CI: 0

Since ancient times, numerous health beneficial effects have been attributed to chocolate, closing up its consumption to a therapeutic use. The present study reviews some relevant studies about chocolate (and its bioactive compounds) on some cardiovascular risk factors and stresses the need of future studies. The consumption of cocoa/ chocolate (i) increases plasma antioxidant capacity, (ii) diminishes platelet function and inflammation, and (iii) decreases diastolic and systolic arterial pressures. Data currently available indicate that daily consumption of cocoa-rich chocolate (rich in polyphenols) may at least partially lower cardiovascular disease risk. Further studies are required in order to establish the bioavailability and mechanisms of action of bioactive compounds in chocolate. The study of the interaction of chocolate and its components with candidate genes will also supply necessary information regarding the individuals best suited to benefit from a potential cardiovascular disease treatment with chocolate.

2017-05-01

Full Text Available Cardiovascular disorders are the leading cause of mortality worldwide. Berberis vulgaris (B. vulgaris is a commonly used plant in traditional medicine. In recent studies, B. vulgaris showed antiarrhythmic, antihypertensive, anticholinergic, and cardioprotective effects. We reviewed the literature to explore the possible prophylactic and therapeutic roles of B. vulgaris in cardiovascular medicine. A computer literature search was conducted to identify all relevant studies that have investigated the role of B. vulgaris in prevention or treatment of cardiovascular diseases.We also searched the citations of the retrieved articles. Using a systematic approach, we conducted a scoping review that included a total of 37 articles. Twelve studies examined the antihypertensive effects of B. vulgaris, seven studies investigated its antiarrhythmic effects, while its inotropic and cardioprotective effects were evaluated in four and eight studies, respectively. B. vulgaris showed a beneficial effect in reducing blood pressure, enhancing cardiac contractility, and protection from reperfusion injury. However, the mechanisms of these effects are still under investigation. Moreover, it could modify major risk factors for cardiovascular disorders, such as oxidative stress, hyperglycemia, and hyperlipidemia. Further studies are needed to translate these findings into effective cardiovascular medications.

The aim of this communication is to describe the cardiovascular risk factors affecting a Mexican urban middle-class population. A convenience sample of 2602 middle class urban subjects composed the cohort of the Lindavista Study, a prospective study aimed to determine if conventional cardiovascular risks factors have the same prognosis impact as in other populations. For the baseline data, several measurements were done: obesity indexes, smoking, blood pressure, fasting serum glucose, total cholesterol, HDL-c, LDL-c and triglycerides. This paper presents the basal values of this population, which represents a sample of the Mexican growing urban middle-class. The mean age in the sample was 50 years; 59% were females. Around 50% of the entire group were overweighed, while around 24% were obese. 32% smoked; 32% were hypertensive with a 20% rate of controlled pressure. 6% had diabetes, and 14% had impaired fasting glucose; 66% had total cholesterol ≥ 200 mg/dL; 62% showed HDL-c levels150 mg/dL, and 34% levels of LDL-c ≥ 160 mg/dL. Half of the population studied had the metabolic syndrome. These data show a population with a high-risk profile, secondary to the agglomeration of several cardiovascular risk factors.

To study the long-term risk of recurrent cardiac, arterial, and venous events in young stroke patients, and whether these risks differed between etiologic subgroups. The study population comprised 970 patients aged 15-49 years from the Helsinki Young Stroke Registry (HYSR) who had an ischemic stroke in 1994-2007. We obtained follow-up data until 2012 from the Finnish Care Register and Statistics Finland. Cumulative 15-year risks were analyzed with life tables, whereas relative risks and corresponding confidence intervals (CI) were based on hazard ratios (HR) from Cox regression analyses. There were 283 (29.2%) patients with a cardiovascular event during the median follow-up of 10.1 years (range 0.1-18.0). Cumulative 15-year risk for venous events was 3.9%. Cumulative 15-year incidence rate for composite vascular events was 34.0 (95% CI 30.1-38.2) per 1,000 person-years. When adjusted for age and sex, patients with an index stroke caused by high-risk sources of cardioembolism had the highest HR for any subsequent cardiovascular events (3.7; 95% CI 2.6-5.4), whereas the large-artery atherosclerosis group had the highest HR (2.7; 95% CI 1.6-4.6) for recurrent stroke compared with patients with stroke of undetermined etiology. The risk for future cardiovascular events after ischemic stroke in young adults remains high for years after the index stroke, in particular when the index stroke is caused by high-risk sources of cardioembolism or large-artery atherosclerosis. © 2016 American Academy of Neurology.

Full Text Available Cardiovascular disease is the leading cause of death for both men and women worldwide. Much emphasis has been placed on the primary and secondary prevention of cardiovascular disease. While depression and anxiety increase the risk of developing cardiovascular disease, cardiovascular disease also increases the risk of developing anxiety and depression. Thus, promoting optimal mental health may be important for both primary and secondary prevention of cardiovascular disease. Like lowering blood pressure, lipids, and body weight, lowering anger and hostility and improving depression and anxiety may also be an important intervention in preventive cardiology. As we strive to further improve cardiovascular outcomes, the next bridge to cross may be one of offering patients nonpharmacologic means for combating daily mental stress and promoting mental health, such as yoga and pranayama. Indeed, the best preventive cardiovascular medicine may be a blend of both Western and Eastern medicine.

Impact of cardiovascular risk factors on medical expenditure: evidence from epidemiological studies analysing data on health checkups and medical insurance.

Science.gov (United States)

Nakamura, Koshi

2014-01-01

Concerns have increasingly been raised about the medical economic burden in Japan, of which approximately 20% is attributable to cardiovascular disease, including coronary heart disease and stroke. Because the management of risk factors is essential for the prevention of cardiovascular disease, it is important to understand the relationship between cardiovascular risk factors and medical expenditure in the Japanese population. However, only a few Japanese epidemiological studies analysing data on health checkups and medical insurance have provided evidence on this topic. Patients with cardiovascular risk factors, including obesity, hypertension, and diabetes, may incur medical expenditures through treatment of the risk factors themselves and through procedures for associated diseases that usually require hospitalization and sometimes result in death. Untreated risk factors may cause medical expenditure surges, mainly due to long-term hospitalization, more often than risk factors preventively treated by medication. On an individual patient level, medical expenditures increase with the number of concomitant cardiovascular risk factors. For single risk factors, personal medical expenditure may increase with the severity of that factor. However, on a population level, the medical economic burden attributable to cardiovascular risk factors results largely from a single, particularly prevalent risk factor, especially from mildly-to-moderately abnormal levels of the factor. Therefore, cardiovascular risk factors require management on the basis of both a cost-effective strategy of treating high-risk patients and a population strategy for reducing both the ill health and medical economic burdens that result from cardiovascular disease.

The prevalence of cardiovascular and metabolic diseases is increased in postmenopausal women, which contributes to the burden of illnesses in this period of life. Yerba mate (Ilex paraguariensis) is a native bush from Southern South America. Its leaves are rich in phenolic components, which may have antioxidant, vasodilating, hypocholesterolemic, and hypoglycemic proprieties. This post hoc analysis of the case-control study nested in the Obesity and Bone Fracture Cohort evaluated the consumption of yerba mate and the prevalence of hypertension, dyslipidemia, and coronary diseases in postmenopausal women. Ninety-five postmenopausal women were included in this analysis. A questionnaire was applied to evaluate the risk factors and diagnosis of cardiovascular diseases and consumption of yerba mate infusion. Student's t-test and chi-square test were used to assess significant differences between groups. The group that consumed more than 1 L/day of mate infusion had significantly fewer diagnoses of coronary disease, dyslipidemia, and hypertension (P<0.049, P<0.048, and P<0.016, respectively). Furthermore, the serum levels of glucose were lower in the group with a higher consumption of yerba mate infusion (P<0.013). The serum levels of total cholesterol, LDL-cholesterol, HDL-cholesterol, and triglycerides were similar between the groups. This pragmatic study points out the benefits of yerba mate consumption for the cardiovascular and metabolic systems. The ingestion of more than 1 L/day of mate infusion was associated with fewer self-reported cardiovascular diseases and lower serum levels of glucose. Longitudinal studies are needed to evaluate the association between yerba mate infusion and reduction of cardiovascular diseases in postmenopausal women.

Full Text Available Abstract Background The EURIKA study aims to assess the status of primary prevention of cardiovascular disease (CVD across Europe. Specifically, it will determine the degree of control of cardiovascular risk factors in current clinical practice in relation to the European guidelines on cardiovascular prevention. It will also assess physicians' knowledge and attitudes about CVD prevention as well as the barriers impeding effective risk factor management in clinical practice. Methods/Design Cross-sectional study conducted simultaneously in 12 countries across Europe. The study has two components: firstly at the physician level, assessing eight hundred and nine primary care and specialist physicians with a daily practice in CVD prevention. A physician specific questionnaire captures information regarding physician demographics, practice settings, cardiovascular prevention beliefs and management. Secondly at the patient level, including 7641 patients aged 50 years or older, free of clinical CVD and with at least one classical risk factor, enrolled by the participating physicians. A patient-specific questionnaire captures information from clinical records and patient interview regarding sociodemographic data, CVD risk factors, and current medications. Finally, each patient provides a fasting blood sample, which is sent to a central laboratory for measuring serum lipids, apolipoproteins, hemoglobin-A1c, and inflammatory biomarkers. Discussion Primary prevention of CVD is an extremely important clinical issue, with preventable circulatory diseases remaining the leading cause of major disease burden. The EURIKA study will provide key information to assess effectiveness of and attitudes toward primary prevention of CVD in Europe. A transnational study creates opportunities for benchmarking good clinical practice across countries and improving outcomes. (ClinicalTrials.gov number, NCT00882336.

Depression, anxiety, and the cardiovascular system: the psychiatrist's perspective.

Science.gov (United States)

Roose, S P

2001-01-01

It is becoming clear that the comorbidity of depression and cardiovascular disease does not occur by chance but rather is an inevitable consequence of the relationship between the conditions. Depression in patients with cardiovascular disease is a significant risk factor for developing symptomatic and fatal ischemic heart disease. Moreover, depressed patients have a higher than expected rate of sudden cardiovascular death. Therefore, appropriate treatment of patients with depression and cardiovascular disease cannot be restricted to considerations of either depression or cardiovascular disease in isolation. The tricyclic antidepressants (TCAs) have various effects on the cardiovascular system, including Type IA antiarrhythmic activity that has been associated with an increased risk of mortality in post-myocardial infarction patients. The selective serotonin reuptake inhibitors (SSRIs) are not associated with adverse cardiac effects. The SSRI paroxetine was compared with a therapeutic level of the TCA nortriptyline in a randomized, controlled study and demonstrated a benign cardiovascular profile, while the TCA induced a significantly higher rate of serious adverse cardiovascular events. On the basis of this favorable cardiovascular profile, the SSRIs should therefore be the preferred choice for the treatment of most patients with comorbid depression and cardiovascular disease. Investigation of putative pathophysiologic mechanisms linking depression and cardiovascular mortality, such as the role of platelet activation, will form the basis for further investigation of antidepressant treatments in order to establish if the antidepressants have a beneficial effect on the prognosis of cardiovascular diseases.

Little is known about the effect of cumulative psychological trauma on health outcomes in patients with cardiovascular disease. The objective of this study was to prospectively examine the association between lifetime trauma exposure and recurrent cardiovascular events or all-cause mortality in patients with existing cardiovascular disease. A total of 1021 men and women with cardiovascular disease were recruited in 2000 to 2002 and followed annually. Trauma history and psychiatric comorbidities were assessed at baseline using the Computerized Diagnostic Interview Schedule for DSM-IV. Health behaviors were assessed using standardized questionnaires. Outcome data were collected annually, and all medical records were reviewed by two independent, blinded physician adjudicators. We used Cox proportional hazards models to evaluate the association between lifetime trauma exposure and the composite outcome of cardiovascular events and all-cause mortality. During an average of 7.5 years of follow-up, there were 503 cardiovascular events and deaths. Compared with the 251 participants in the lowest trauma exposure quartile, the 256 participants in the highest exposure quartile had a 38% greater risk of adverse outcomes (hazard ratio = 1.38, 95% confidence interval = 1.06-1.81), adjusted for age, sex, race, income, education, depression, posttraumatic stress disorder, generalized anxiety disorder, smoking, physical inactivity, and illicit drug abuse. Cumulative exposure to psychological trauma was associated with an increased risk of recurrent cardiovascular events and mortality, independent of psychiatric comorbidities and health behaviors. These data add to a growing literature showing enduring effects of repeated trauma exposure on health that are independent of trauma-related psychiatric disorders such as depression and posttraumatic stress disorder.

Although huge and long-lasting research efforts have been spent on the development of new diagnostic techniques investigating cardiovascular diseases, still fundamental challenges exist; the main challenge being the diagnosis of a suspected or known coronary artery disease or its consequences (myocardial infarction, heart failure etc.). Beside morphological techniques, functional imaging modalities are available in clinical diagnostic algorithms, whereas molecular cardiovascular imaging techniques are still under development. This review summarizes clinical-diagnostical challenges of modern cardiovascular medicine as well as the potential of new molecular imaging techniques to face these. (orig.)

Cardiovascular: radioisotopic angiocardiography

Radioisotopic angiocardiography, performed after the intravenous injection of 99 /sup m/Tc-labeled pertechnetate or albumin, is a simple, rapid, and safe procedure which permits identification and physiologic assessment of a wide variety of congenital and acquired cardiovascular lesions in infants and children. These include atrial and ventricular septal defect, tetralogy of Fallot, pulmonic stenosis, aortopulmonary window, transposition of the great vessels, valvular stenosis and/or insufficiency, myocardial lesions, and lesions of the great vessels. The simplicity of the procedure lends itself to repeated measurements to assess the effects of therapy or to follow the course of the disease. A wide spectrum of congenital and acquired cardiovascular diseases have been studied which have particular application to the pediatric age group. (auth)

The inter-arm systolic blood pressure difference (SBPD) is recommended to be in relation to potential cardiovascular disease (CVD). Previous studies yielded controversial results about the association between an inter-arm SBPD ≥ 10 mmHg or ≥15 mmHg and the risk of cardiovascular mortality. Therefore, we conducted this meta-analysis to investigate this association. We searched PubMed and Embase databases through December 31, 2014, and examined the references of retrieved articles to identify relevant cohort studies. We utilized Newcastle-Ottawa scale to assess the quality of included studies and calculated the summary risk estimates in a fixed/random-effect model. All data analyses were conducted using STATA version 11.0. A total of seven studies were identified. Compared with participants with an inter-arm SBPD arm SBPD ≥ 10 mmHg was 1.58 (95% CI: 1.3-1.93), and the pooled HR of cardiovascular mortality of participants with an inter-arm SBPD ≥ 15 mmHg versus those with an inter-arm SBPD arm SBPD may define a subpopulation at high risk of CVD events.

Many studies have investigated the association between restless legs syndrome (RLS) and cardiovascular risk factors, leading to conflicting results. Therefore, the aim of the current study was to determine whether RLS is associated with cardiovascular risk factors and disease. This cross-sectional study included 5,324 consecutive subjects who visited the Physical Examination Center of The First Affiliated Hospital of Zhengzhou University for their yearly routine physical examination. Participants underwent a face-to-face interview with a neurologist for the assessment of RLS, based on the International Restless Legs Study Group criteria. They also completed a questionnaire related to cardiovascular risk factors and other health-related and demographic information. Logistic regression was used to assess which of the demographic and cardiovascular risk factors increased the odds of RLS. Then, unadjusted and adjusted models were designed to determine whether RLS was associated with increased odds of cardiovascular disease, coronary artery disease, or hypertension. RLS was observed in 9.2% of the participants. Multivariable logistic regression models, which included the covariates age, sex, body mass index, smoking status, hypercholesterolemia, and Pittsburgh Sleep Quality Index score (dichotomized at 5), demonstrated that female sex (odds ratio [OR]: 2.42, 95% confidence interval [CI]: 1.99-2.95), smoking (OR: 1.96, 95% CI: 1.31-2.92), high cholesterol (OR: 1.30, 95% CI: 1.03-1.64), and PSQI score > 5 (OR: 5.61, 95% CI: 2.14-14.69) are significantly associated with RLS. Additionally, RLS was associated with hypertension, after adjusting for age, sex, body mass index, smoking, hypercholesterolemia, Pittsburgh Sleep Quality Index score > 5, diabetes, anemia, and decreased renal function. RLS is associated with the prevalence of hypertension but not with that of cardiovascular disease or coronary artery disease. © 2018 American Academy of Sleep Medicine.

Caffeine and cardiovascular health.

This report evaluates the scientific literature on caffeine with respect to potential cardiovascular outcomes, specifically relative risks of total cardiovascular disease (CVD), coronary heart disease (CHD) and acute myocardial infarction (AMI), effects on arrhythmia, heart failure, sudden cardiac arrest, stroke, blood pressure, hypertension, and other biomarkers of effect, including heart rate, cerebral blood flow, cardiac output, plasma homocysteine levels, serum cholesterol levels, electrocardiogram (EKG) parameters, heart rate variability, endothelial/platelet function and plasma/urine catecholamine levels. Caffeine intake has been associated with a range of reversible and transient physiological effects broadly and cardiovascular effects specifically. This report attempts to understand where the delineations exist in caffeine intake and corresponding cardiovascular effects among various subpopulations. The available literature suggests that cardiovascular effects experienced by caffeine consumers at levels up to 600 mg/day are in most cases mild, transient, and reversible, with no lasting adverse effect. The point at which caffeine intake may cause harm to the cardiovascular system is not readily identifiable in part because data on the effects of daily intakes greater than 600 mg is limited. However, the evidence considered within this review suggests that typical moderate caffeine intake is not associated with increased risks of total cardiovascular disease; arrhythmia; heart failure; blood pressure changes among regular coffee drinkers; or hypertension in baseline populations.

Patients with Addison's disease (AD) have increased cardiovascular mortality. To study visceral fat and conventional and exploratory cardiovascular risk factors in patients with AD. A cross-sectional, single-center, case-control study. Patients (n = 76; n = 51 women) with AD and 76 healthy control subjects were matched for sex, age, body mass index (BMI), and smoking habits. The primary outcome variable was visceral abdominal adipose tissue (VAT) measured using computed tomography. Secondary outcome variables were prevalence of metabolic syndrome (MetS) and 92 biomarkers of cardiovascular disease. The mean ± standard deviation age of all subjects was 53 ± 14 years; mean BMI, 25 ± 4 kg/m2; and mean duration of AD, 17 ± 12 years. The median (range) daily hydrocortisone dose was 30 mg (10 to 50 mg). Median (interquartile range) 24-hour urinary free cortisol excretion was increased in patients vs controls [359 nmol (193 to 601 nmol) vs 175 nmol (140 to 244 nmol); P 1] and vasodilatory protective marker was decreased (FC, <1). Twenty-six patients (34%) vs 12 control subjects (16%) fulfilled the criteria for MetS (P = 0.01). Despite higher cortisol exposure, VAT was not increased in patients with AD. The prevalence of MetS was increased and several biomarkers of cardiovascular disease were adversely affected in patients with AD. Copyright © 2017 Endocrine Society

PPAR-γ in the Cardiovascular System

Sheng Zhong Duan

2008-01-01

Full Text Available Peroxisome proliferator-activated receptor-γ (PPAR-γ, an essential transcriptional mediator of adipogenesis, lipid metabolism, insulin sensitivity, and glucose homeostasis, is increasingly recognized as a key player in inflammatory cells and in cardiovascular diseases (CVD such as hypertension, cardiac hypertrophy, congestive heart failure, and atherosclerosis. PPAR-γ agonists, the thiazolidinediones (TZDs, increase insulin sensitivity, lower blood glucose, decrease circulating free fatty acids and triglycerides, lower blood pressure, reduce inflammatory markers, and reduce atherosclerosis in insulin-resistant patients and animal models. Human genetic studies on PPAR-γ have revealed that functional changes in this nuclear receptor are associated with CVD. Recent controversial clinical studies raise the question of deleterious action of PPAR-γ agonists on the cardiovascular system. These complex interactions of metabolic responsive factors and cardiovascular disease promise to be important areas of focus for the future.

Full Text Available Epidemiological studies have examined the effect of coffee intake on cardiovascular disease, but the benefits and risks for the cardiovascular system remain controversial. Our objective was to evaluate the association between coffee consumption and its polyphenols on cardiovascular risk factors. Data came from the “Health Survey of São Paulo (ISA-Capital” among 557 individuals, in São Paulo, Brazil. Diet was assessed by two 24-h dietary recalls. Coffee consumption was categorized into <1, 1–3, and ≥3 cups/day. Polyphenol intake was calculated by matching food consumption data with the Phenol-Explorer database. Multiple logistic regression models were used to assess the associations between cardiovascular risk factors (blood pressure, total cholesterol, low-density lipoprotein cholesterol (LDL-c, high-density lipoprotein cholesterol (HDL-c, triglycerides, fasting glucose, and homocysteine and usual coffee intake. The odds were lower among individuals who drank 1–3 cups of coffee/day to elevated systolic blood pressure (SBP (Odds Ratio (OR = 0.45; 95% Confidence Interval (95% CI: 0.26, 0.78, elevated diastolic blood pressure (DBP (OR = 0.44; 95% CI: 0.20, 0.98, and hyperhomocysteinemia (OR = 0.32; 95% CI: 0.11, 0.93. Furthermore, significant inverse associations were also observed between moderate intake of coffee polyphenols and elevated SBP (OR = 0.46; 95% CI: 0.24, 0.87, elevated DBP (OR = 0.51; 95% CI: 0.26, 0.98, and hyperhomocysteinemia (OR = 0.29; 95% CI: 0.11, 0.78. In conclusion, coffee intake of 1–3 cups/day and its polyphenols were associated with lower odds of elevated SBP, DBP, and hyperhomocysteinemia. Thus, the moderate consumption of coffee, a polyphenol-rich beverage, could exert a protective effect against some cardiovascular risk factors.

An unhealthy lifestyle can increase the risk of cardiovascular disease. However, the mechanism by which lifestyle influences the development of cardiovascular disease remains unclear. Since coronary endothelial function is a predictor of cardiovascular prognosis, the goal of this study was to characterize the effect of enjoying hobbies on coronary endothelial function and cardiovascular outcomes. A total of 121 consecutive patients (76 men, 45 women) with almost normal coronary arteries underwent Doppler flow study of the left anterior descending coronary artery following sequential administration of papaverine, acetylcholine, and nitroglycerin. On the basis of responses to questionnaires, patients were divided into two groups; the Hobby group (n = 71) who enjoyed hobbies, and the Non-hobby group (n = 50) who had no hobbies. Cardiovascular outcomes were assessed at long-term follow-up using medical records or questionnaire surveys for major adverse cardiovascular events (MACE).The average follow-up period was 916 +/- 515 days. There were no significant differences in demographics when comparing the two groups. The percent change in coronary blood flow and coronary artery diameter induced by acetylcholine was significantly greater in the Hobby group than in the Non-hobby group (49% +/- 77% vs 25% +/- 37%, P hobbies was the only independent predictor of MACE (odds ratio 8.1 [95% confidence interval 1.60, 41.90], P = 0.01) among the variables tested. In the early stages of arteriosclerosis, enjoying hobbies may improve cardiovascular outcomes via its favorable effects on coronary endothelial function.

Effect of ionizing radiation on cardiovascular system

International Nuclear Information System (INIS)

Milliat, F.; Benderitter, M.; Gaugler, M.H.

2011-01-01

Radiotherapy treatment for cancer of the chest, mediastinal area or the neck area is associated with increased risk of cardiovascular disease. With the increasing number of cancer patients and the increased treatment efficiency, the number of cancer survivors is increasing exponentially. The cancer survivors live longer and their long-term follow-up must be considered. The cardiovascular toxicity is mainly associated with the treatment of breast cancer, Hodgkin's lymphoma and head and neck cancer. Radiation-induced cardiovascular effects are insidious and chronic. Their occurrence is linked to numerous factors including the age of the patient at the beginning of the radiotherapy schedule, the number of years following radiotherapy, the doses (and volume) to the heart and the large vessels (coronary and carotid arteries), and the association with the traditional cardiovascular risk factors. Pathophysiological mechanisms remain unclear and, even if similarities with age-related atherosclerosis were established, the specificities of the radiation-induced atherosclerosis for high doses remain to be discovered. For low/moderate doses of ionising radiation, recent epidemiological studies provide evidence of increased risk of cardiovascular pathologies. A better knowledge of the mechanisms associated with the radiation-induced cardiovascular pathologies and the more precise identification of the populations at risk in the future should allow a more effective care of these patients with cardiovascular risk.

Robert, Marie; Miossec, Pierre

2017-09-01

Cardiovascular diseases remain the leading cause of death worldwide and account for most of the premature mortality observed in chronic inflammatory diseases. Common mechanisms underlie these two types of disorders, where the contribution of Interleukin (IL)-17A, the founding member of the IL-17 family, is highly suspected. While the local effects of IL-17A in inflammatory disorders have been well described, those on the cardiovascular system remain less studied. This review focuses on the effects of IL-17 on the cardiovascular system both on isolated cells and in vivo. IL-17A acts on vessel and cardiac cells, leading to inflammation, coagulation and thrombosis. In vivo and clinical studies have shown its involvement in the pathogenesis of cardiovascular diseases including atherosclerosis and myocardial infarction that occur prematurely in chronic inflammatory disorders. As new therapeutic approaches are targeting the IL-17 pathway, this review should help to better understand their positive and negative outcomes on the cardio-vascular system.

2018-02-28

Atherosclerosis is a disease which develops very gradually over decades. Under the influence of modifiable cardiovascular risk factors, such as blood pressure, LDL-cholesterol level, smoking or lifestyle, clinical symptoms of atherosclerosis manifest more or less early in life. When cardiovascular risk factors accumulate, the risk of having a cardiovascular event increases and the benefits of prevention measures are greater. This article summarizes existing strategies for controlling modifiable cardiovascular risk factors in primary prevention. The physician can rely on an interprofessional network of cardiovascular prevention. Managing risk factors while respecting the autonomy and priorities of the patient will bring the greatest benefit.

Full Text Available In China, diabetes prevalence is rising rapidly, but little is known about the associated risks and population burden of cardiovascular diseases. We assess associations of diabetes with major cardiovascular diseases and the relevance of diabetes duration and other modifiable risk factors to these associations.A nationwide prospective study recruited 512,891 men and women aged 30-79 y between 25 June 2004 and 15 July 2008 from ten diverse localities across China. During ~7 y of follow-up, 7,353 cardiovascular deaths and 25,451 non-fatal major cardiovascular events were recorded among 488,760 participants without prior cardiovascular disease at baseline. Cox regression yielded adjusted hazard ratios (HRs comparing disease risks in individuals with diabetes to those without. Overall, 5.4% (n = 26,335 of participants had self-reported (2.7% or screen-detected (2.7% diabetes. Individuals with self-reported diabetes had an adjusted HR of 2.07 (95% CI 1.90-2.26 for cardiovascular mortality. There were significant excess risks of major coronary event (2.44, 95% CI 2.18-2.73, ischaemic stroke (1.68, 95% CI 1.60-1.77, and intracerebral haemorrhage (1.24, 95% CI 1.07-1.44. Screen-detected diabetes was also associated with significant, though more modest, excess cardiovascular risks, with corresponding HRs of 1.66 (95% CI 1.51-1.83, 1.62 (95% CI 1.40-1.86, 1.48 (95% CI 1.40-1.57, and 1.17 (95% CI 1.01-1.36, respectively. Misclassification of screen-detected diabetes may have caused these risk estimates to be underestimated, whilst lack of data on lipids may have resulted in residual confounding of diabetes-associated cardiovascular disease risks. Among individuals with diabetes, cardiovascular risk increased progressively with duration of diabetes and number of other presenting modifiable cardiovascular risk factors. Assuming a causal association, diabetes now accounts for ~0.5 million (489,676, 95% CI 335,777-681,202 cardiovascular deaths annually in China

Lipoprotein metabolism indicators improve cardiovascular risk prediction.

Directory of Open Access Journals (Sweden)

Daniël B van Schalkwijk

Full Text Available BACKGROUND: Cardiovascular disease risk increases when lipoprotein metabolism is dysfunctional. We have developed a computational model able to derive indicators of lipoprotein production, lipolysis, and uptake processes from a single lipoprotein profile measurement. This is the first study to investigate whether lipoprotein metabolism indicators can improve cardiovascular risk prediction and therapy management. METHODS AND RESULTS: We calculated lipoprotein metabolism indicators for 1981 subjects (145 cases, 1836 controls from the Framingham Heart Study offspring cohort in which NMR lipoprotein profiles were measured. We applied a statistical learning algorithm using a support vector machine to select conventional risk factors and lipoprotein metabolism indicators that contributed to predicting risk for general cardiovascular disease. Risk prediction was quantified by the change in the Area-Under-the-ROC-Curve (ΔAUC and by risk reclassification (Net Reclassification Improvement (NRI and Integrated Discrimination Improvement (IDI. Two VLDL lipoprotein metabolism indicators (VLDLE and VLDLH improved cardiovascular risk prediction. We added these indicators to a multivariate model with the best performing conventional risk markers. Our method significantly improved both CVD prediction and risk reclassification. CONCLUSIONS: Two calculated VLDL metabolism indicators significantly improved cardiovascular risk prediction. These indicators may help to reduce prescription of unnecessary cholesterol-lowering medication, reducing costs and possible side-effects. For clinical application, further validation is required.

While demand for cardiovascular surgery is expected to increase gradually along with the rapid increase in cardiovascular diseases with respect to the aging population, the supply of thoracic and cardiovascular surgeons has been continuously decreasing over the past 10 years. Consequently, this study aims to achieve guidance in establishing health care policy by analyzing the supply and demand for cardiovascular surgeries in the medical service area of Korea. After investigating the actual number of cardiovascular surgeries performed using the National Health Insurance claim data of the Health Insurance Review and Assessment Service, as well as drawing from national statistics concerning the elderly population aged 65 and over, this study estimated the number of future cardiovascular surgeries by using a cell-based model. To be able to analyze the supply and demand of surgeons, the recent status of new surgeons specializing in thoracic and cardiovascular surgeries and the ratio of their subspecialties in cardiovascular surgeries were investigated. Then, while taking three different scenarios into account, the number of cardiovascular surgeons expected be working in 5-year periods was projected. The number of cardiovascular surgeries, which was recorded at 10,581 cases in 2014, is predicted to increase consistently to reach a demand of 15,501 cases in 2040-an increase of 46.5%. There was a total of 245 cardiovascular surgeons at work in 2014. Looking at 5 year spans in the future, the number of surgeons expected to be supplied in 2040 is 184, to retire is 249, and expected to be working is 309-an increase of -24.9%, 1.6%, and 26.1%, respectively compared to those in 2014. This forecasts a demand-supply imbalance in every scenario. Cardiovascular surgeons are the most central resource in the medical service of highly specialized cardiovascular surgeries, and fostering the surgeons requires much time, effort, and resources; therefore, by analyzing the various factors

NKT cells in cardiovascular diseases.

van Puijvelde, Gijs H M; Kuiper, Johan

2017-12-05

Despite life-style advice and the prescription of cholesterol-lowering and anti-thrombotic drugs, cardiovascular diseases are still the leading cause of death worldwide. Therefore, there is an urgent need for new therapeutic strategies focussing on atherosclerosis, the major underlying pathology of cardiovascular diseases characterized by an accumulation of lipids in an inflamed arterial/vessel wall. CD1d-restricted lipid-sensing natural killer T (NKT) cells, bridging the innate and adaptive immunity, and CD1d-expressing antigen-presenting cells are detected in atherosclerotic lesions of mice and humans. In this review we will summarize studies that point to a critical role for NKT cells in the pathogenesis of atherosclerosis and other cardiovascular diseases by the secretion of pro-atherogenic cytokines and cytotoxins. These pro-atherogenic NKT cells are potential targets for new therapeutic strategies in the prevention and treatment of cardiovascular diseases. Additionally, proteins transferring lipids during atherosclerosis, which are also important in the loading of lipids onto CD1d and possible endogenous ligands responsible for the activation of NKT cells during atherosclerosis will be discussed.

Air pollution is a worrying factor and has an impact on public health. Multiple studies relate exposure to air pollutants with an increase in cardiovascular events, cardiovascular mortality and mortality for all causes. A relationship has also been demonstrated between increased pollution and high blood pressure, as well as a higher prevalence of hypertension. Pollutants that play a more relevant role in this association are particulate matters, nitrogen dioxide and sulphur dioxide. The objective of this review is to understand the mechanisms involved in this increase and to find the most recent publications that relate pollution, cardiovascular risk and hypertension.

Full Text Available Nitrogen oxide (NOx is produced during combustion at high temperature, which is a major constituent of air pollutants. Recent studies suggested inconsistent results on the association between NOx exposure and cardiovascular-related malformations. We aimed to assess aforementioned association in pregnant women in the first trimester and cardiovascular-related malformations of infants. A systematic literature review identified studies for observational studies about NOx exposure and cardiovascular-related malformation in PubMed. Random-effect models were used to estimate summary odds ratio (SOR and 95% confidence intervals (CIs for aforementioned association. Finally, nine studies met the inclusion criteria. Overall, the SOR of cardiovascular-related malformation per 10 ppb increment in NOx and NO2 concentration was 1.01 (95% CI: 0.98–1.04; I2 = 38.6%, P=0.09 and 0.99 (95% CI: 0.95–1.04; I2 = 37.8%, P=0.13, respectively. Stratifying by study design, geographic locations, and confounded adjustments, the majority of strata showed negative results, which were consistent with the main findings. However, we found that exposure to NOx and NO2 in the first trimester increased the risk of coarctation of the aorta (COA malformation by 13% and 19%, respectively. Our study provided limited evidence regarding the association between NOx exposure in the first trimester and cardiovascular-related malformations in infants.

Background Familial hypercholesterolaemia increases the risk for cardiovascular disease. The primary aim of the present study was to describe sex differences in incidence and prevalence of cardiovascular disease leading to hospitalisation in a complete cohort of genotyped familial hypercholesterolaemia patients. Design and methods In this registry study data on 5538 patients with verified genotyped familial hypercholesterolaemia were linked to data on all Norwegian cardiovascular disease hospitalisations, and hospitalisations due to pre-eclampsia/eclampsia, congenital heart defects and diabetes. Results During 1994-2009 a total of 1411 of familial hypercholesterolaemia patients were hospitalised, and ischaemic heart disease was reported in 90% of them. Mean (SD) age at first hospitalisation and first re-hospitalisation was 45.1 (16.5) and 47.6 (16.3) years, respectively, with no sex differences ( P = 0.66 and P = 0.93, respectively). More men (26.9%) than women (24.1%) with familial hypercholesterolaemia were hospitalised ( P = 0.02). The median (25th-75th percentile) number of hospital admissions was four (two to seven) per familial hypercholesterolaemia patient, with no sex differences ( P = 0.87). Despite having familial hypercholesterolaemia at the time of hospitalisation, the diagnosis of familial hypercholesterolaemia was registered in only 45.7% of the patients at discharge. Conclusion Most cardiovascular disease hospitalisations were due to ischaemic heart disease. Familial hypercholesterolaemia patients were first time hospitalised at age 45.1 years, with no significant sex differences in age, which are important novel findings. The awareness and registration of the familial hypercholesterolaemia diagnosis during the hospital stays were disturbingly low.

Cardiovascular effects. Chapter 3.1

The cardiovascular effects of various radioprotective substances are reviewed. Reports of the cardiovascular reactions of different species have been analysed to show that there is no relationship between the principal cardiovascular activities and the specific effects of the radioprotective agents; sometimes radioprotection develops simultaneously with a general lowering of arterial pressure, sometimes it occurs with a rise in blood pressure. In contrast, lowered arterial pressure in the chicken is not sufficient to raise the resistance to X-rays. No common characteristics were revealed by a comparative study of the effects of radioprotective agents on blood pressure, histamine liberation and concentration of catecholamines in blood. The effect on tissue perfusion, at the level of the microcirculation, may be of more significance, but techniques are not yet available for investigating the mechanism of action at this level.

Full Text Available Cardiovascular problem is one of the leading cause of death in Malaysia and now invaded to the sub-urban and rural areas. To prevent and control of this problem, several main risk factors needed to be known and shall be reexamined and ranked according to the priority. The objectives of this research paper was to identify several dominant risk factor related to cardiovascular problem. A cross sectional study was carried out from March 2000 – June 2001 on a total of 8159 rural population aged 18 and above to measure the prevalence of the common cardiovascular risk factors. Those risk factors are systolic blood pressure, diastolic blood pressure, serum cholesterol level, obesity index, blood glucose level, smoking, physical activity and mental stress. Overall prevalence of common cardiovascular risk factors were higher, dominated by physical inactivity (65.7%, hypercholesterolemia – TC:HC (62.3%, mental stress (55.5% and obesity (53.7%. Smoking was also high at 49.9% especially among men. However systolic hypertension, diastolic hypertension and diabetes mellitus; although increased by age, its prevalence is relatively low at 23.7%, 19.2%, and 6.3% respectively. Cardiovascular risk factors related to lifestyle are much evidenced as compared to risk factors related to the biological influence. Therefore, all initiatives in community health intervention should be mobilized specifically on prevention and control of lifestyle-related risk factors.

Industrial air pollutants from Upper Silesia, Poland, contain over 250 polycyclic and heterocyclic aromatic hydrocarbons and heavy metals, including mutagenic and carcinogenic chemicals that have been shown to from DNA adducts. Over 4 million habitants of Silesia are permanently exposed to the industrial pollution by pulmonary and dermal routes and by contaminated food and water. These chemicals, when examined separately in animals models, were proven immunotoxic. We studied the extrapulmonary immunotoxic potential of a typical mixture of Silesian filter-suspended matter from a selected area, over a specific season and time period. Early changes in the immune system were analyzed in BALB/c mice exposed ip to acute doses of 20-330 mg dust mixture/kg body weight (0.06-1.0 LD50). No major changes were noted for weight and the cellularity of spleen, liver and kidneys. However, dramatic decrease in thymus weight index and thymocyte cell count were noted as early as 24-72 h postexposure, which correlated with almost complete depletion of immature, double-positive CD4{sup +}CD8{sup +} thymocytes. Changes in spleen were less profound; however, increased depletion of B cells over T cells was noted at high doses of the suspended matter. Exposure to the airborne dust also decreased cytokine production by spleen cells, such as interferon-{gamma} (IFN-{gamma}) and tumor necrosis factor-{alpha} (TNF-{alpha}). Overall, a single exposure to Silesian dust, even at the relatively low 0.06 LD50 dose, affected lymphokine production, suppressed B-cell proliferative response, and depleted thymuses of immature, double-positive CD4{sup +}CD8{sup +} cells. A chemical synergism is suspected. To our knowledge, none of the known components of Silesian suspended matter, when examined as a single chemical, was shown to exert such a profound biological effect. 32 refs., 5 figs.

Full Text Available Background: Mortality and morbidity due cardiovascular diseases in India is on the rise. Metabolic Syndrome which is a collection of risk factors of metabolic origin, can greatly contribute to its rising burden. Aims & Objectives: The present study was conducted with the objective of estimating the prevalence of metabolic syndrome and 10-year cardiovascular risk among adults. Material & Methods: This hospital-based study included 260 adults aged 20-60 years. Metabolic Syndrome was defined using National Cholesterol Education Program –Adult Treatment Panel -3 criteria. The 10 year cardiovascular risk was estimated using Framingham risk scoring. Results: The overall prevalence of metabolic syndrome among the study participants was 38.8%. Age (41-60yrs, male gender and daily consumption of high salt items were positively associated with metabolic syndrome whereas consumption of occasional high sugar items showed an inverse association with metabolic syndrome. According to Framingham Risk Scoring, 14.3% of the participants belonged to intermediate/high risk category. Conclusion: With a high prevalence of metabolic syndrome and a considerable proportion of individuals with intermediate to high 10 yr CVD risk, there is a need to design strategies to prevent future cardiovascular events.

Risk of cardiovascular disease following radiation exposure

International Nuclear Information System (INIS)

Trivedi, A.; Vlahovich, S.; Cornett, R.J.

2001-01-01

Excess radiation-induced cardiac mortalities have been reported among radiotherapy patients. Many case reports describe the occurrence of atherosclerosis following radiotherapy for Hodgkin's disease and breast cancer. Some case reports describe the cerebral infarction following radiotherapy to neck region, and of peripheral vascular disease of the lower extremities following radiotherapy to the pelvic region. The association of atomic bomb radiation and cardiovascular disease has been examined recently by incidence studies and prevalence studies of various endpoints of atherosclerosis; all endpoints indicated an increase of cardiovascular disease in the exposed group. It is almost certain that the cardiovascular disease is higher among atomic bomb survivors. However, since a heavy exposure of 10-40 Gy is delivered in radiotherapy and the bomb survivors were exposed to radiation at high dose and dose-rate, the question is whether the results can be extrapolated to individuals exposed to lower levels of radiation. Some recent epidemiological studies on occupationally exposed workers and population living near Chernobyl have provided the evidence for cardiovascular disease being a significant late effect at relatively low doses of radiation. However, the issue of non-cancer mortality from radiation is complicated by lack of adequate information on doses, and many other confounding factors (e.g., smoking habits or socio-economic status). This presentation will evaluate possible radiobiological mechanisms for radiation-induced cardiovascular disease, and will address its relevance to radiation protection management at low doses and what the impact might be on future radiation risk assessments.

2014-12-01

Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease that disproportionately affects women during their childbearing years. Cardiovascular disease is the leading cause of mortality in this patient population at an age when women often have low cardiovascular risk. Hypertension is a major cardiovascular disease risk factor, and its prevalence is markedly increased in women with SLE. Estrogen has traditionally been implicated in SLE disease progression because of the prevalence of the disease in women; however, its role in cardiovascular risk factors such as hypertension is unclear. The objective of this review is to discuss evidence for the role of estrogen in both human and murine SLE with emphasis on the effect of estrogen on cardiovascular risk factors, including hypertension. PubMed was used to search for articles with terms related to estradiol and SLE. The references of retrieved publications were also reviewed. The potential permissive role of estrogen in SLE development is supported by studies from experimental animal models of lupus in which early removal of estrogen or its effects leads to attenuation of SLE disease parameters, including autoantibody production and renal injury. However, data about the role of estrogens in human SLE are much less clear, with most studies not reaching firm conclusions about positive or negative outcomes after hormonal manipulations involving estrogen during SLE (ie, oral contraceptives, hormone therapy). Significant gaps in knowledge remain about the effect of estrogen on cardiovascular risk factors during SLE. Studies in women with SLE were not designed to determine the effect of estrogen or hormone therapy on blood pressure even though hypertension is highly prevalent, and risk of premature ovarian failure could necessitate use of hormone therapy in women with SLE. Recent evidence from an experimental animal model of lupus found that estrogen may protect against cardiovascular risk factors in

Full Text Available Abstract Background Exposure to intermittent magnetic fields of 16 Hz has been shown to reduce heart rate variability, and decreased heart rate variability predicts cardiovascular mortality. We examined mortality from cardiovascular causes in railway workers exposed to varying degrees to intermittent 16.7 Hz magnetic fields. Methods We studied a cohort of 20,141 Swiss railway employees between 1972 and 2002, including highly exposed train drivers (median lifetime exposure 120.5 μT-years, and less or little exposed shunting yard engineers (42.1 μT-years, train attendants (13.3 μT-years and station masters (5.7 μT-years. During 464,129 person-years of follow up, 5,413 deaths were recorded and 3,594 deaths were attributed to cardio-vascular diseases. We analyzed data using Cox proportional hazards models. Results For all cardiovascular mortality the hazard ratio compared to station masters was 0.99 (95%CI: 0.91, 1.08 in train drivers, 1.13 (95%CI: 0.98, 1.30 in shunting yard engineers, and 1.09 (95%CI: 1.00, 1.19 in train attendants.Corresponding hazard ratios for arrhythmia related deaths were 1.04 (95%CI: 0.68, 1.59, 0.58 (95%CI: 0.24, 1.37 and 1.30 (95%CI: 0.87, 1.93 and for acute myocardial infarction 1.00 (95%CI: 0.73, 1.36, 1.56 (95%CI: 1.04, 2.32, and 1.14 (95%CI: 0.85, 1.53. The hazard ratio for arrhythmia related deaths per 100 μT-years of cumulative exposure was 0.94 (95%CI: 0.71, 1.24 and 0.91 (95%CI: 0.75, 1.11 for acute myocardial infarction. Conclusion This study provides evidence against an association between long-term occupational exposure to intermittent 16.7 Hz magnetic fields and cardiovascular mortality.

Atherogenic dyslipidemia is an important risk factor for cardiovascular disease. We aim to determine atherogenic dyslipidemia prevalence in primary care patients at moderate-very high cardiovascular risk and its associated cardiovascular risk perception in Spain. This cross-sectional study included 1137 primary care patients. Patients had previous cardiovascular disease, diabetes mellitus, SCORE risk ≥ 3, severe hypertension or dyslipidemia. Atherogenic dyslipidemia was defined as low HDL-C (<40 mg/dL [males], <50 mg/dL [females]) and elevated triglycerides (≥ 150 mg/dL). A visual analog scale was used to define a perceived cardiovascular disease risk score. Mean age was 63.9 ± 9.7 years (64.6% males). The mean BMI was 29.1 ± 4.3 kg/m(2), and mean waist circumference 104.2 ± 12.7 cm (males), and 97.2 ± 14.0 cm (females). 29.4% were smokers, 76.4% had hypertension, 48.0% were diabetics, 24.7% had previous myocardial infarction, and 17.8% peripheral arterial disease. European guidelines classified 83.6% at very high cardiovascular risk. Recommended HDL-C levels were achieved by 50.1% of patients and 37.3% had triglycerides in the reference range. Target LDL-C was achieved by 8.8%. The overall atherogenic dyslipidemia prevalence was 27.1% (34.1% in diabetics). This prevalence in patients achieving target LDL-C was 21.4%. Cardiovascular risk perceived by patients was 4.3/10, while primary care physicians scored 5.7/10. When LDL-C levels are controlled, atherogenic dyslipidemia is more prevalent in those patients at highest cardiovascular risk and with diabetes. This highlights the importance of intervention strategies to prevent the residual vascular risk in this population. Both patients and physicians underestimated cardiovascular risk.

Frailty in older age is known to be associated with cardiovascular disease (CVD) risk. However, the extent to which frailty is associated with the CVD risk profile has been little studied. Our aim was to examine the associations of a range of cardiovascular risk factors with frailty and to assess whether these are independent of established CVD. Cross-sectional study of a socially representative sample of 1622 surviving men aged 71-92 examined in 2010-2012 across 24 British towns, from a prospective study initiated in 1978-1980. Frailty was defined using the Fried phenotype, including weight loss, grip strength, exhaustion, slowness and low physical activity. Among 1622 men, 303 (19%) were frail and 876 (54%) were pre-frail. Compared with non-frail, those with frailty had a higher odds of obesity (OR 2.03, 95% CI 1.38 to 2.99), high waist circumference (OR 2.30, 95% CI 1.67 to 3.17), low high-density lipoprotein-cholesterol (HDL-C) (OR 2.28, 95% CI 1.47 to 3.54) and hypertension (OR 1.79, 95% CI 1.27 to 2.54). Prevalence of these factors was also higher in those with frailty (prevalence in frail vs non-frail groups was 46% vs 31% for high waist circumference, 20% vs 11% for low HDL and 78% vs 65% for hypertension). Frail individuals had a worse cardiovascular risk profile with an increased risk of high heart rate, poor lung function (forced expiratory volume in 1 s (FEV1)), raised white cell count (WCC), poor renal function (low estimated glomerular filtration rate), low alanine transaminase and low serum sodium. Some risk factors (HDL-C, hypertension, WCC, FEV1, renal function and albumin) were also associated with being pre-frail. These associations remained when men with prevalent CVD were excluded.

Central blood pressure (BP) is a promising marker to identify subjects with higher cardiovascular risk than expected by traditional risk factors. Significant results have been obtained in populations with high cardiovascular risk, but little is known about low-cardiovascular-risk patients, although the differences between central and peripheral BP (amplification) are usually greater in this population. The study aim was to evaluate central BP over 24 hours for cardiovascular event prediction in hypertensive subjects with low cardiovascular risk. Peripheral and central BPs were recorded during clinical visits and over 24 hours in hypertensive patients with low cardiovascular risk (Systematic Coronary Risk Evaluation ≤5%). Our primary end point is the occurrence of a cardiovascular event during follow-up. To assess the potential interest in central pulse pressure over 24 hours, we performed Cox proportional hazard models analysis and comparison of area under the curves using the contrast test for peripheral and central BP. A cohort of 703 hypertensive subjects from Bordeaux were included. After the first 24 hours of BP measurement, the subjects were then followed up for an average of 112.5±70 months. We recorded 65 cardiovascular events during follow-up. Amplification was found to be significantly associated with cardiovascular events when added to peripheral 24-hour pulse pressure ( P =0.0259). The area under the curve of 24-hour central pulse pressure is significantly more important than area under the curve of office BP ( P =0.0296), and there is a trend of superiority with the area under the curve of peripheral 24-hour pulse pressure. Central pulse pressure over 24 hours improves the prediction of cardiovascular events for hypertensive patients with low cardiovascular risk compared to peripheral pulse pressure. © 2018 The Authors.

Full Text Available   Abstract INTRODUCTION: Adult cardiovascular disease has its root in childhood. Cardiovascular disease aggregates in families, so identification of high-risk families and early screening and control of cardiovascular risk factors in offspring will help prevent cardiovascular disease. This study was performed to determine the relationship between cardiovascular risk factors in parents having a positive history of premature myocardial infarction and their offspring. methods: This cross-sectional study was conducted in 2004 on 91 parents and their offspring (91 children. The parents were randomly selected from among patients hospitalized in the critical care unit of Vali-e-Asr hospital with premature myocardial infarction. Important indicators such as systolic blood pressure (SBP, diastolic blood pressure (DBP, body mass index (BMI, total cholesterol (TC, triglyceride (TG, low-density lipoprotein cholesterol (LDL-C and high-density lipoprotein cholesterol (HDL-C were measured in both groups. results: There was no significant relation of systolic and diastolic blood pressure between parents and their offspring. Thirty-three percent of the parents were hypertensive. No cases of hypertension were found in children. Mean systolic and diastolic blood pressure were significantly higher in the children of hypertensive parents. Significant relations were seen between BMI and obesity in parents and their children. There was no significant relation between serum lipids, high TC, high LDL-C and low HDL-C levels in parents and their children. The commonest lipid disorder in parents and their offspring was low HDL-C. CONCLUSIONS: The results of this study show a significant relation between hypertension, obesity and blood lipid disorders between parents with positive history of premature myocardial infraction and their children. Hence, screening programs in these children for detection of cardiovascular risk factors are recommended.     Keywords

Burn shock, a complex process, which develops following burn leads to severe and unique derangement of cardiovascular function. Patients with preexisting comorbidities such as cardiovascular diseases may be more susceptible. We therefore sought to examine the impact of preexisting cardiovascular disease on burn outcomes. A retrospective analysis of patients admitted to a regional burn center from 2002 to 2012. Independent variables analyzed included basic demographics, burn mechanism, presence of inhalation injury, TBSA, pre-existing comorbidities, and length of ICU/hospital stay. Bivariate analysis was performed and Poisson regression modeling was utilized to estimate the incidence of being in the ICU and mortality. There were a total of 5332 adult patients admitted over the study period. 6% (n=428) had a preexisting cardiovascular disease. Cardiovascular disease patients had a higher mortality rate (16%) compared to those without cardiovascular disease (3%, pwill likely be a greater number of individuals at risk for worse outcomes following burn. This knowledge can help with burn prognostication. Copyright © 2017 Elsevier Ltd and ISBI. All rights reserved.

Full Text Available Uma condição clínica muito comum é SAOS, que está associada a várias doenças cardiovasculares, incluindo hipertensão arterial sistêmica, fibrilação atrial e aterosclerose. A associação entre SAOS e doença cardiovascular não é somente uma consequência da sobreposição de fatores de risco, incluindo obesidade, sedentarismo, ser do sexo masculino e ter idade maior. Existem evidências crescentes de que SAOS contribui de forma independente para o aparecimento e a progressão de várias doenças cardiovasculares. Os mecanismos pelos quais SAOS pode afetar o sistema cardiovascular são múltiplos e incluem a ativação do sistema nervoso simpático, inflamação sistêmica, resistência a insulina e geração de estresse oxidativo. Existem evidências que o tratamento de SAOS com CPAP pode reduzir a pressão arterial, sinais precoces de aterosclerose, risco de recorrência de fibrilação atrial e mortalidade, principalmente por acidente vascular cerebral e infarto agudo do miocárdio, em pacientes com SAOS grave.Obstructive sleep apnea syndrome (OSAS is a common condition associated with various cardiovascular diseases, including systemic arterial hypertension, atrial fibrillation, and atherosclerosis. The association between OSAS and cardiovascular disease has been related to the overlapping of risk factors, including obesity, having a sedentary lifestyle, being male, and being older. However, there is mounting evidence that OSAS can also independently contribute to the development and progression of various cardiovascular diseases. The mechanisms by which OSAS can affect the cardiovascular system are multiple, including the activation of the sympathetic nervous system, systemic inflammation, insulin resistance, and oxidative stress. There is also evidence that the treatment of OSAS with CPAP can reduce arterial blood pressure, early signs of atherosclerosis, the risk of atrial fibrillation recurrence, and mortality (principally

Coronary artery fluorine-18-sodium fluoride (F-NaF) uptake reflects coronary artery calcification metabolism and is considered to be an early prognostic marker of coronary heart disease. This study evaluated the relationship between coronary artery F-NaF uptake and cardiovascular risk in healthy adults at low cardiovascular risk. Study participants underwent blood pressure measurements, blood analyses, and coronary artery F-NaF PET/CT imaging. In addition, the 10-year risk for the development of cardiovascular disease, on the basis of the Framingham Risk Score, was estimated. Multivariable linear regression evaluated the dependence of coronary artery F-NaF uptake on cardiovascular risk factors. We recruited 89 (47 men, 42 women) healthy adults aged 21-75 years. Female sex (0.34 kBq/ml; P=0.009), age (0.16 kBq/ml per SD; P=0.002), and BMI (0.42 kBq/ml per SD; Prisk factors present (Prisk for the development of cardiovascular disease was on average 2.4 times higher in adults with coronary artery F-NaF uptake in the highest quartile compared with those in the lowest quartile of the distribution (8.0 vs. 3.3%, Prisk and that an unfavorable cardiovascular risk profile is associated with a marked increase in coronary artery F-NaF uptake.

Previous studies suggest that patients with hyperthyroidism remain at an increased risk of cardiovascular morbidity even after restoring euthyroidism. The mechanisms of the increased risk and its dependency on the different treatment modalities of hyperthyroidism remain unclear. The aim of this long-term follow-up study was to compare the rate of hospitalizations for cardiovascular causes and the mortality in hyperthyroid patients treated surgically with an age- and gender-matched reference population. A population-based cohort study was conducted among 4334 hyperthyroid patients (median age 46 years) treated with thyroidectomy in 1986-2007 in Finland and among 12,991 reference subjects. Firstly, the hospitalizations due to cardiovascular diseases (CVD) were analysed until thyroidectomy. Secondly, the hazard ratios for any new hospitalization due to CVDs after the thyroidectomy were calculated in Cox regression analysis adjusted with the prevalent CVDs at the time of thyroidectomy. The risk of hospitalization due to all CVDs started to increase already 5 years before the thyroidectomy, and by the time of the operation, it was 50% higher in the hyperthyroid patients compared to the controls (P hyperthyroidism. Despite the increased CVD morbidity among the patients, there was no difference in cardiovascular mortality. The present study shows that hyperthyroidism increases the risk of hospitalization due to CVDs and the risk is sustained up to two decades after effective surgical treatment. However, there was no excess CVD mortality in the middle-aged patient cohort studied. © 2013 John Wiley & Sons Ltd.

Elevation in blood pressure (BP) increases risk for all cardiovascular events. Nevertheless, the extent to which different indices of BP elevation may be associated to varying degrees with different cardiovascular outcomes remains unclear. We studied 13340 participants (aged 54 ± 6 years, 56% women and 27% black) of the Atherosclerosis Risk in Communities Study who were free of baseline cardiovascular disease. We used Cox proportional hazards models to compare the relative contributions of systolic BP, diastolic BP, pulse pressure, and mean arterial pressure to risk for coronary heart disease, heart failure, stroke, and all-cause mortality. For each multivariable-adjusted model, the largest area under the receiver-operating curve (AUC) and smallest -2 log-likelihood values were used to identify BP measures with the greatest contribution to risk prediction for each outcome. A total of 2095 coronary heart disease events, 1669 heart failure events, 771 stroke events, and 3016 deaths occurred during 18 ± 5 years of follow-up. In multivariable analyses adjusting for traditional cardiovascular risk factors, the BP measures with the greatest risk contributions were the following: systolic BP for coronary heart disease (AUC=0.74); pulse pressure for heart failure (AUC=0.79); systolic BP for stroke (AUC=0.74); and pulse pressure for all-cause mortality (AUC=0.74). With few exceptions, results were similar in analyses stratified by age, sex, and race. Our data indicate that distinct BP components contribute variably to risk for different cardiovascular outcomes.

Full Text Available Interleukin-6 (IL-6 is a cytokine involved in inflammatory process, as well as in glucose and lipid metabolism. Several studies of the biological relevance of IL-6 gene polymorphisms have indicated a relationship with cardiovascular disease. The aim of this study was to assess whether the –174 G/C and –572 G/C of IL-6 gene polymorphisms are associated with cardiovascular risk factors in Mexican families. Ninety members of 30 Mexican families, in which an index case (proband had obesity, were included in the study. We evaluated the body composition by bioelectrical impedance. Peripheral blood samples were collected to determine biochemical and hematological parameters. High sensitivity C- reactive protein levels were measurement for nephelometric analysis. Screening for both polymorphisms studied was performed by PCR-RFLP. In the parents, both polymorphisms were in Hardy-Weinberg's equilibrium. The genotypes –174 GC/CC were associated with T2D (OR = 1.23, IC95% 1.01–1.5 and highest levels of hsCRP (p = 0.02, whereas genotype –572 GG was associated with T2D (OR = 1.24, IC95% 1.04–1.47 with an inflammatory state determined by the increase in the leukocyte count (OR = 1.24, IC95% 1.02–1.51. The genotypes –174 GC/CC and –572 GG may confer susceptibility for the development of subclinical inflammation and type 2 diabetes in Mexican families.

Cardiovascular imaging technologies continue to increase in their capacity to capture and store large quantities of data. Modern computational methods, developed in the field of machine learning, offer new approaches to leveraging the growing volume of imaging data available for analyses. Machine learning methods can now address data-related problems ranging from simple analytic queries of existing measurement data to the more complex challenges involved in analyzing raw images. To date, machine learning has been used in 2 broad and highly interconnected areas: automation of tasks that might otherwise be performed by a human and generation of clinically important new knowledge. Most cardiovascular imaging studies have focused on task-oriented problems, but more studies involving algorithms aimed at generating new clinical insights are emerging. Continued expansion in the size and dimensionality of cardiovascular imaging databases is driving strong interest in applying powerful deep learning methods, in particular, to analyze these data. Overall, the most effective approaches will require an investment in the resources needed to appropriately prepare such large data sets for analyses. Notwithstanding current technical and logistical challenges, machine learning and especially deep learning methods have much to offer and will substantially impact the future practice and science of cardiovascular imaging. © 2017 American Heart Association, Inc.

The objective of this study was to estimate the risk of a cardiovascular event or death associated with modern radiation in a population of elderly female breast cancer patients with varying baseline cardiovascular risk. The data used for this analysis are from the linked Surveillance, Epidemiology, and End-Results (SEER)-Medicare database. The retrospective cohort study included women aged 66 years and older with stage 0–III breast cancer diagnosed between 2000 and 2005. Women were grouped as low, intermediate, or high cardiovascular risk based on the presence of certain clinical diagnoses. The risk for the combined outcome of a hospitalization for a cardiovascular event or death within 6 months and 24 months of diagnosis was estimated using a multivariable Cox model. The median follow-up time was 24 months. Among the 91,612 women with American Joint Committee on Cancer (AJCC) stage 0–III breast cancer: 39,555 (43.2%) were treated with radiation therapy and 52,057 (56.8%) were not. The receipt of radiation therapy in the first 6 months was associated with a statistically significant increased risk for the combined outcome in women categorized as high risk (HR = 1.510; 95% CI, 1.396–1.634) or intermediate risk (HR = 1.415; 95% CI, 1.188–1.686) but not low risk (HR = 1.027; 95% CI, 0.798–1.321). Women with a prior medical history of cardiovascular disease treated with radiation therapy are at increased risk for an event and should be monitored for at least 6 months following treatment with radiation therapy

Epidemiological studies have demonstrated the beneficial effect of plant-derived food intake in reducing the risk of cardiovascular disease (CVD). The potential bioactivity of cocoa and its polyphenolic components in modulating cardiovascular health is now being studied worldwide and continues to grow at a rapid pace. In fact, the high polyphenol content of cocoa is of particular interest from the nutritional and pharmacological viewpoints. Cocoa polyphenols are shown to possess a range of cardiovascular-protective properties, and can play a meaningful role through modulating different inflammatory markers involved in atherosclerosis. Accumulated evidence on related anti-inflammatory effects of cocoa polyphenols is summarized in the present review. PMID:24566441
