Filter by:Background: Heart failure (HF) is a chronic disease with a very important and increasingly severe social and health impact with a prevalence of 6.8% in Spain. HF with preserved ejection fraction (HFpEF) represents approximately 50% of all patients with HF. In the absence of pharmacological treatments that have succeeded in reducing mortality or morbidity in this pathology, it is recommended that interventions be directed at prevention, symptomatic treatment of HF and treatment of comorbidities to avoid exacerbations, thus physical exercise is recognized as an important adjunct in the treatment of HF and is recommended by the guidelines of the American College of Cardiology (ACC)/American Heart Association (AHA) and the European Society of Cardiology (ESC). Currently, aerobic exercise is the most studied physical exercise in this population, but in recent years high-intensity interval training (HIIT) and the combination of aerobic exercise with strength training (combined exercise) have emerged. Objectives: The overall objective of this study is to compare the effectiveness of combined training and HIIT on exercise capacity, diastolic function, endothelial function, and arterial stiffness in patients with HFpEF. The specific objectives of this study are: a) to compare the effectiveness of combined training and HIIT on quality of life in patients with HFpEF and b) to analyze the cost-effectiveness of combined training and HIIT versus conventional treatment in patients with HFpEF. Methodology: The ExIC-FEp study will be a single-blind randomized clinical trial with 3 arms (combined exercise, HIIT and a control group), conducted at the Health and Social Research Center of the University of Castilla-La Mancha, to analyze two types of supervised physical exercise in patients with HFpEF for 6 months. Patients with HFpEF will be randomly assigned (1:1:1) to the combined exercise, HIIT or control group. All participants will be examined, at baseline (prior to randomization), at three months (mid-intervention) and at six months (at the end of the intervention). Participants will undergo physical examination, echocardiography, maximal cardiopulmonary stress test, and measurement of endothelial function and arterial stiffness. In addition, sociodemographic variables, quality of life, physical activity, adherence to the Mediterranean diet, strength, spirometry and blood sampling will be measured. Expected scientific contributions: this randomized clinical trial will represent a a significant advance in the scientific evidence available on the efficacy of physical exercise in the treatment of HFpEF, through: (a) transfer of the results to physicians, nurses and patients; (b) dissemination of results through scientific articles, doctoral theses and participation in congresses; (c) press releases and press conferences with the aim of disseminating the research results to the population; (d) dissemination through social networks to improve the social impact; and (e) design and content development of a web page.
The purpose of this study is to investigate the effect of blood flow restriction (BFR) resistance training on vascular function. The investigators aim to compare the effects of different BFR devices (wide-rigid cuffs and narrow elastic bands) on vascular function. The investigators hypothesize that BFR resistance training with wide-rigid cuffs might have a minor negative effect (short-term and reversible) on vascular function, while BFR resistance training with narrow-elastic bands may improve vascular function. Both training methods are equally effective in increasing muscle strength.
The present study is designed to evaluate the modulatory effect of IP on the vascular endothelial function. To assess its vasodilatation potential, change in flow mediated dilation (FMD) and blood flow velocity (BFV) will be assessed in healthy adult male population.
SCI results in higher incidence of heart disease and diabetes and heart disease is the most common cause of death. Chronic inflammation, deleterious changes in vascular structure and impaired glucose metabolism are risk factors that contribute to both heart disease and diabetes. While exercise can help reduce these risk factors, paralysis and impaired accessibility often precludes exercise in persons with SCI. New research in able-bodied persons demonstrates passive heating decreases inflammation and improves vascular function. Similar studies in persons with SCI suggest they may also have the same health benefits however these studies only investigated the impact of short term (one episode) passive heating (as opposed to repeated bouts). Repeated bouts of heat exposure will likely be required to impact chronic inflammation, but this has never been tested in persons with SCI. This study will test the impact of repeated bouts (3x/week) of passive heat stress over a longer term (8 weeks) on inflammation, metabolism and vascular function.
The purpose of this study is to characterize microvascular reactivity on the forearm muscle using non-invasive near-infrared spectroscopy in critically ill COVID-19 patients, and to correlate its alterations with 28-day mortality in ICU COVID-19 patients.
The main objective of the study is to evaluate the endothelial function of WAK2017. In addition the effects on the blood pressure and the parameters of lipid metabolism will be explored.
This is a phase 4, single center, randomized, open-labeled, cross-over design study. The primary objective of the study is to compare effect of dapagliflozine and metformin on endothelial function. Subjects are randomized to initial metformin or initial dapagliflozin group and maintained initial treatment for 8 weeks. During that period, dose of dapagliflozin is maintained 10mg/day and metformin can be titrated upto 2000 mg/day. After 1 weeks of washout period, 8 weeks' cross-over is followed.
This is a phase 4, single center, randomized, open-labeled study. The primary objective of the study is to compare effect of gemigliptin and acarbose on endothelial function. Subjects are randomized to gemigliptin or acarbose group and maintained intial treatment for 4 weeks.
- To test the hypothesis that therapy with high dose statin provides endothelial superior benefit to the same cholesterol lowering with low-dose statin combined with ezetimibe. - To test the hypothesis that therapy with high dose statin provides anti-inflammatory effect than the same reduction of cholesterol with low dose of statin plus ezetimibe
We are comparing the blood pressure-lowering effects of two marketed medications, Coreg CR and Toprol XL. Although both drugs reduce blood pressure by blocking the action of noradrenaline on beta-receptors in the blood vessels, Coreg CR also blocks alpha-receptors, which may provide added blood pressure-lowering. In addition, Coreg CR may have anti-oxidant actions. Cells which line blood vessels (termed "endothelial cells") make nitric oxide (NO), which relaxes the muscle cells encircling the blood vessels, causing a reduction in blood pressure. When body cells use oxygen, they normally produce "free radicals", which can destroy NO,leading to high blood pressure, heart damage and worsenimg of diabetes. Antioxidants remove free radicals and prevent or repair this damage. In this study we will measure endothelial cell function, blood vessel wall stiffness, NO in exhaled breath, and blood levels of substances which reflect NO production and destruction to determine if a pure beta-blocker (Toprol XL) differs from an alpha/beta blocker (Coreg CR) in these effects. We will also examine the mechanism by which such differences might occur.
