Filter by:Hypertension has high prevalence and poor control rates and is considered one of the major modifiable risk factors for cardiovascular system diseases, and one of the most important public health problems. The imbalance of the autonomic cardiovascular control, which can be considered as a major etiologic factor in the development of essential hypertension is characterized by increased sympathetic activity and reduced parasympathetic activity possible. Cardiovascular disease is the leading cause of death and disability in the world and autonomic imbalance is associated with several pathological conditions, and may be a final common pathway for the increased morbidity and mortality of cardiovascular diseases. In this sense, the heart rate variability (HRV) is a quantitative marker of sympathetic and parasympathetic activity, which can be used to assess disease and mortality as a noninvasive technique. TENS is a noninvasive therapeutic modality, easy to handle, it has no side effects or interactions with medications being used for the relief of pain by sensory stimulation through peripheral nerves and mainly for control and treatment of acute and chronic pain . Research on the effect of TENS on the sympathetic and parasympathetic nervous system activity remain controversial, especially regarding the parameters to use. The aim of this study is to investigate the effects of TENS on the sympathetic and parasympathetic nervous system in patients with hypertension by heart rate variability and blood pressure variability. This is a randomized clinical trial, double blind, where hypertensive patients were randomized to three groups: high-frequency TENS (100 Hz) n = 20, low frequency TENS (4 Hz) n = 20 and n = 20 placebo. Evaluations will be made in a single session. The results will be assessed by a blinded investigator and randomization will be done electronically. It is expected to evaluate how often TENS exerts more influence in the modulation of sympathetic and parasympathetic system.
Cardiovascular disease (CVD) remains the leading cause of death in the United States, and improved CVD risk assessment is needed for personalized medicine. Atherosclerosis measures including plaque volume and adverse plaque features have prognostic value. Novel techniques have been developed for assessing carotid, coronary, and femoral atherosclerosis using magnetic resonance imaging (MRI) methods that are rapid and reproducible, have improved spatial resolution, and do not require contrast media, making atherosclerosis assessment in multiple vascular beds feasible during a single MRI session. This pilot research will provide preliminary data to develop an innovative global atherosclerosis measure including carotid, coronary, and femoral vascular beds, for assessing cardiovascular risk and for monitoring atherosclerosis response to therapy. 20 participants will be recruited in one year.
IBERICAN is a multicenter, longitudinal and observational population-based study of patients daily attended in Primary Care setting in Spain. This study is aimed to determine the prevalence and incidence of cardiovascular risk factors in adult population in Spain. Patients will be followed-up for a minimum period of 5 years, every 6 months or a lesser period when clinically required. It has been estimated that a total of 15,000 individuals will be included.
This study evaluates the effectiveness of a yogurt enriched with bioactive lipids extracted from olive mill waste in platelet aggregation and other inflammatory and oxidative stress markers. The study will include three groups: the intervention group will receive the enriched yogurt while the other two groups will serve as controls (plain yogurt and no yogurt consumption).
The primary aim of our present study is to evaluate the effect of a targeted, intensified, multidimensional intervention compared to conventional treatment of modifiable risk factors for CVD in patients with early RA. The primary endpoint, a composite of death from cardiovascular causes, non-fatal MI, non-fatal stroke and re-vascularisation, will be assessed after 5years' follow-up.
Obesity is epidemic in Australia, and current preventative strategies have had limited success in alleviating this health crisis. While numerous options are available for treatment of obesity, most do not result in sustained weight reduction. Obesity results from an imbalance between energy intake and expenditure, therefore new methods that correct this imbalance are essential for effective long-term treatment. Rodent studies show that brown adipose tissue (BAT) can burn more energy than any other tissue in the body, therefore targeting BAT to increase its activity (energy burning rate) and quantity in humans is potentially a powerful tool for the treatment of obesity and related diseases. BAT has only recently been irrefutably identified in adult humans therefore little is known about how it functions in humans.
The aim of Prevent CardioKids is to evaluate to what extend disturbed vascular function markers are already present in children of different weight categories and whether these are age dependent. Also differences - and relationships - between vascular function measurements and plasma biomarkers between lean and overweight/obese children will be compared.
Heart disease and stroke are the number one killers world-wide. When someone has hypertension, the constantly elevated blood pressure damages their blood vessels and the organs that they supply blood to. This causes stroke, heart attack, heart failure, kidney failure and dementia. Finding and lowering high blood pressure to normal with lifestyle changes and if necessary medications, lowers the risk of these outcomes. Canada has high rates of blood pressure control compared to other countries in the world, due in large part to the successful dissemination of hypertension guidelines. However remote and disadvantaged communities have not been as successful and need additional measures to help achieve the same level of blood pressure control as the rest of the country. The DREAM-GLOBAL team has extensive experience working with Canada's Aboriginal Communities and a large community in Tanzania. The DREAM-GLOBAL project will integrate innovations in technology with the implementation of guidelines-based blood pressure control and through partnerships with experts in government and industry, overcome barriers to lowering blood pressure in Canada's Aboriginal Communities, and in a community in Tanzania. Tools will be developed and tested that will close the circle of care around people with hypertension by bringing measurement data to the medical record and health care provider and also sending useful medical feedback to the person with hypertension via secure data servers and routine SMS messaging on cell phones. The system will be tested for effectiveness of diagnosing and also for managing hypertension. To begin the process of preventing hypertension, the team will also explore with an Aboriginal community how to create policies to reduce the sodium content in their food. If proven effective, DREAM-GLOBAL can also become a platform for managing other chronic diseases.
The major cause of mortality worldwide is due to cardiovascular diseases. A way to treat these diseases is coronary artery bypass grafting, one of the most common surgical procedures in the world. The incidence of post-operative complications contributes to functional decline of the patient, reduced quality of life and post-discharge mortality. Also, cardiac surgery leads to changes in lung capacity and respiratory muscle strength, causing a decrease in the function lung. Physical therapy proves to be an effective tool to combat changes resulting from cardiac surgery, demonstrating beneficial results in the pulmonary function, functional capacity, and peripheral and respiratory muscle strength. The Pilates method has been studied as a therapeutic way to healthy subjects and various kinds of diseases, but there are no studies in the literature evaluating the effect method in patients after coronary artery bypass surgery. The aim of this study is to investigate the effect of Pilates on functional capacity , flows and lung volumes, respiratory and peripheral muscle strength after coronary artery bypass grafting. Randomized clinical trial in which patients will be eligible after elective coronary artery bypass surgery, randomly allocated into two groups : conventional physiotherapy group (n = 15) and Pilates method associated with conventional physiotherapy group (n = 15). The outcomes will be assessed by blinded evaluator and data randomization will be performed through by electronic randomization.The interventions will take place during the length of stay in the hospital, totalizing a maximum of six days of intervention. It is expected that the application of the Pilates method exercise method associated with conventional physiotherapy in patients in postoperative coronary artery bypass grafting improves functional capacity, flows and lung volumes and respiratory and peripheral muscle strength.
The epidemic data shows that prehypertension is associated with cardiovascular disease, and heavy dietary salt intake could improve the developing of hypertension. We detected the risk factors of coronary atherosclerosis of prehypertensive patients with different levels of salt intake. The aim of this multicenter prospective, randomized controlled study is to evaluate regular physical exercise and salt diet effects on progression of coronary artery disease in patients with prehypertension.
