Filter by:The primary objective for this study is to prove the safety and effectiveness of the Spectranetics Turbo-Elite catheter in atherectomy treatment for infrainguinal arteries with catheter to vessel sizing of at least 50%.
Currently investigators do not have diagnostic and prognostic markers for SSc which almost always starts with a vascular disease (Raynaud's disease) isolated for several years. The primary purpose is to highlight discriminating metabolic profiles depending on the characteristics of the disease, allowing early diagnosis of SSc at the onset of vascular lesions, by comparing the profiles of SSc beginners (<3 years) to established forms (> 3 years). Secondary purposes: - Prognosis: to study the metabolomics profile of SSc when a visceral complication occurs - Diagnosis: to compare the metabolomics profile of SSc to undifferentiated connective tissue disease (UCDT), Raynaud's disease (RD), vascular disease (VD) and healthy controls - Exploratory: to compare the metabolomics profile of blood, urine and skin of SSc patients
Double-blind, randomised, placebo-controlled, parallel group study with two intervention arms. The study will be conducted in 150 subjects and the primary objective is to show a fasting LDL-cholesterol and triglyceride lowering effect of plant sterols in subjects with established type 2 diabetes mellitus and subjects at high risk of developing type 2 diabetes.
The objective of this study is to evaluate the performance of the Zilver PTX stent thumbwheel delivery system.
Patients are being asked to be in this research study because medical researchers hope that by gathering information about a large number of children with pulmonary hypertension over time, their understanding of the disease process will increase and lead to better treatment. Investigators believe that pulmonary hypertension in children is different than pulmonary hypertension in adults and this study will help us understand those differences.
25-30% of women with preexisting vascular disease (chronic hypertension/diabetes/obesity) will develop pre-eclampsia and or growth restriction. In addition, the frequency of stillbirths in this group is dramatically increased over the general population. Pregnancy complications in this very heterogeneous group are likely to be a combination of a failure of the maternal vasculature to adapt to pregnancy and/or a failure of placental development. The relative contribution of these two mechanisms is poorly understood and current preventative strategies (aspirin) in this group only prevent a small number of adverse outcomes. This important and complex group have been inadequately investigated to date mainly because of the diversity of their underlying disease complicating prospective research studies. The evolution of tools which allow more detailed assessments of both uteroplacental blood flow and maternal vascular function will enable us to perform prospective studies in these women and to develop targeted preventative measures. Recent biomarker studies have also identified a number of biomarkers which have not yet been assessed in these high risk groups.
The purpose of this study is to investigate the prevalence of signs and symptoms of hypogonadism in three groups of testicular cancer survivors.
Collect confirmatory evidence of the safety and effectiveness of the Balloon LIFESTREAM™ Stent Graft for the treatment of stenoses and occlusion in the iliac arteries.
The purpose of this study is to assess the impact of frailty as a multidimensional risk factor on the outcomes of adult cardiac and vascular surgery. For the purpose of defining patient frailty a multimodal questionnaire has been developed including measurement of psychological, socioeconomical, neurological and behavioral aspects. This study also features an investigation of the possible relationship between sudden regional weather changes, individual meteorological susceptibility of the patients and the outcomes of adult cardiac and vascular surgery.
Cardiovascular disease (CVD), including coronary heart disease (CHD) and stroke, is a leading cause of morbidity and mortality. Dyslipidemia has long been recognized to be the most important risk factor in the development of atherosclerosis in human beings. In Taiwan, the rates for hypercholesterolemia (≧250mg/dl) were 4.3% and 5.5% in 1970; 12.99% in 1980; and 17.1% in 1990. Those for hypertriglyceridemia (≧200 mg/dl) were 6.5% and 11.1% in 1970 and 13.0% in 1990. Low serum HDL-C was an isolated and independent coronary risk factor among a good number of Taiwanese people. Lowering of low-density lipoprotein cholesterol (LDL-C) with statins has in the last decade become part of the standard treatment regimen in patients with dyslipidemia. However, most embarrassing, is the insufficient data for clinical use in Taiwan. It is necessary to have rationalized and balanced guideline for the management of dyslipidemia in Taiwan, based on our local epidemiological, clinical and basic research data. Because all these trials were conducted in Caucasians and no large-scaled end-point research about the lipid lowering therapy (LLT) was published in Asians before, this registry study attempts to define the status of lipid lowering therapy in Taiwan and the effect of LLT on CVD morbidity and mortality in a large population of patients receiving primary or secondary prevention therapy. The medications will only depend on the decision made by the primary care physicians. The patient or physician can decide to be withdrawn from this registry at any time because of any reason. The lipid profile change, myopathy, or liver enzyme change after the LLT will also be recorded.
