Active clinical trials for "Syndrome"

Cohort study using data from Clinical Practice Research Datalink (CPRD). The study cohort includes all patients who received at least one prescription for ticagrelor for the first time between December 2010 and March 2015, following ACS. Patient baseline characteristics will be described: (Age, Gender, Body Mass Index, Smoking status, Sociodemographic status), type of ACS and interventions, CV history and comorbidities, bleeding and respiratory history. The following outcomes will be examined: Incidence of vascular events (composite MI, Stroke, vascular death, specific vascular event and all cause death), incidence of bleeding and incidence of dysponea. Time to event for vascular events, bleeding and dyspnoea.

Beta Blocker therapy is a mainstay of treatment following acute coronary syndromes (ACS), particularly acute myocardial infarction (MI). Studies have repeatedly demonstrated the benefit of Beta blocker therapy following either ST-segment elevation myocardial infarction (STEMI) or non-ST-segment elevation ACS,and Beta blocker therapy has been a performance measure used to grade hospital performance by the Centers for Medicare and Medicaid Services and Joint Commission on Accreditation of Healthcare Organizations.Although the benefit of Beta blocker therapy has been clearly demonstrated, the doses that have been used in many of these studies are significantly higher than those typically used currently in clinical practice.The benefit of Beta blockers has been ascribed to dose-related heart rate reduction,although alternative mechanisms for their benefit have also been proposed.In addition, the classical Beta blocker trials were performed decades ago, before the modern therapeutic era,which includes reperfusion therapy, potent antithrombotics, and statins. This raises the question of whether titration of Beta blocker therapy to the high doses that had been previously studied provides substantial incremental benefit in current clinical practice over the more frequently prescribed and clinically tolerated doses of Beta blockers.Moreover, a recent study has reported that high-dose Beta blockers were not superior to low-dose Beta blockers,aprovocative finding requiring validation. And until now, there has been no registry on patients with ACS about Between Beta-blocker Treatment in Henan, the most populated (about 100 million) and predominantly rural (66%)province in central China. This multicenter, prospective, observational study is aimed to analyze the application status and long-term prognostic benefit of beta-blockers in patients with acute coronary syndrome.

Current evaluation of patients suspected of non-ST-elevation acute coronary syndrome is greatly dictated by the results of high-sensitivity troponins. In a substantial number of patients this approach does not provide a conclusive work-up. Patients typically present with slightly elevated high-sensitivity troponins without significant changes during serial sampling and no other clinical clues that can aid in determining the etiology of their chest pain complaints. Uncertainty remains about the optimal diagnostic management of these patients and they are often admitted to undergo invasive angiography. Coronary CT angiography can improve efficiency of clinical care in these patients by reducing unnecessary hospital admissions and invasive angiography. In this study, the investigators will investigate whether a diagnostic strategy comprising of early coronary CT angiography is more clinically efficient than standard optimal care in patients with an inconclusive work-up for non-ST-elevation acute coronary syndrome.

Polycystic ovary syndrome is the most common endocrine disorder in women of reproductive age, with a prevalence of approximately 5-10%. Polycystic ovary syndrome is diagnosed according to Rotterdam criteria by at least two of the following three key features: oligomenorrhea or amenorrhea; clinical and/or biochemical signs of hyperandrogenism; the presence of polycystic ovaries on ultrasound and exclusion of other endocrine disorders including hyperprolactinemia, thyroid dysfunction and congenital adrenal hyperplasia. Polycystic ovary syndrome is also associated with insulin resistance, obesity and disorders of lipid metabolism, as well as infertility, although these findings have not been addressed in the Rotterdam criteria. Polycystic ovary syndrome is the major cause of anovulatory infertility. The recent studies suggest that anovulation resulting from ovarian follicle abnormalities in Polycystic ovary syndrome patients are 2-fold of normal ovaries. Firstly, early follicular growth is excessive, thus women with Polycystic ovary syndrome are characterized by an excessive number of small antral follicles (2- to 3-fold of normal ovaries). Secondly, the selection of one follicle from the increased pool of selectable follicles and its further maturation to a dominant follicle does not occur. This second abnormality in the folliculogenesis can cause menstrual dysfunction presented as oligomenorrhea or amenorrhea. Historically, Polycystic ovary syndrome treatment has not been curative in nature, instead treatments focus on resolution of clinical manifestations of the disease.

A retrospective, systematic study of reimbursed healthcare costs over a 10 year period in patients suffering from Familial Chylomicronaemia Syndromes (FCS) or Multifactorial Chylomicronaemia Syndromes (MCS) in order to establish the relative healthcare burden of both syndromes by linking the Hospices Civils de Lyon (HCL) registry of FCS or MCS patients and data obtained from FCS or MCS patients followed in Paris, Nantes and Lyon to the French National Health System (NHS) healthcare claims database, the Système National d'Information Inter-Régimes de l'Assurance Maladie (SNIIR-AM). A probabilistic approach will be used to link databases. This linkage will be based on the following variables: age, gender, date of discharge of any hospitalization, date of any imaging procedure. This study will help to describe, in real life, the management of severe hyperglyceridaemia in France. In addition, the descriptive results will help obtain a better understanding of the patients suffering from this disease, the burden of the disease and the healthcare consumption linked to this disease. Even if this consumption of care has been relatively unexplored until this point, it is not negligible. The potential of merging genomics and claims data for cardiovascular research could help to identify ways to optimize disease

Epicardial adipose tissue (EAT) is a visceral adipose tissue that surrounds the heart and the coronary arteries. It is metabolically active, secreting pro- and anti-inflammatory mediators and cytokines. With increasing EAT volume, inflammatory activity increasing, which suggests that EAT may locally influence atherosclerosis development in the coronary artery tree. The amount of EAT is associated with cardiovascular disease risk factors as well as presence and progression of subclinical atherosclerosis. Likewise, EAT volume is increased in patient with prevalent and incident coronary artery disease manifestation. In the setting of acute coronary syndrome, EAT was found to be associated with the TIMI risk score and Syntax II score. While CT imaging of the heart is the gold standard for EAT quantification, transthoracic echocardiography allows for a quick and reliable assessment of EAT thickness, as has been used in research studies and may qualify for routine EAT assessment in clinical routine.However, currently data on how quantification of EAT in clinical routine may impact patient management is lacking. We aim to investigate, whether quantification of EAT thickness via transthoracic echocardiography enables improved risk stratification in patients presenting with acute chest pain to the emergency department.

Cyclic vomiting syndrome is a disorder characterized by nausea and vomiting, separated by periods without any symptoms. There is very little research on this field at this point and most doctors do not fully understand the disorder. The goal of this study is to assess how the stomach empties food. Participants will be asked to participate in this study because either (a) they have been diagnosed and/or treated for cyclic vomiting syndrome in the past, or (b) they are physically healthy. The study seeks to compare how a healthy person's stomach empties to how the stomach of someone with cyclic vomiting disorder empties.

The primary purpose of this study is to better understand the impact of the Society of Critical Care Medicine (SCCM) THRIVE Collaboratives on patients, their families and clinicians. The investigators have formed an international and interprofessional evaluative team with experts in the field in an effort to explore interactions between survivors and THRIVE. This approach is reflective of the international ethos of SCCM and its collaboratives, with the potential to improve the generalizability of this survivorship research to different health systems.

The main objective is to evaluate middle term compliance (≥ 2 years) of the Mandibular Advancement Devices Tali® in patients with Syndrome of Obstructive Sleep Apnea and Hypopneas.

Reliable patient reported outcome measures (PROM's) for symptom assessment in irritable bowel syndrome are essential in order to investigate natural disease course and potential treatment options aimed at symptom improvement, since biological markers are currently unavailable. Currently used symptom assessment methods, i.e. end-of-day or end-of-week questionnaires, have considerable limitations. The Experience Sampling Method (ESM), an electronic questioning method characterized by random and repeated, momentary assessments in the subject's current state and environment, might overcome these limitations. Aim of this study is to validate an IBS-specific electronic patient-reported outcome measure, based on the Experience Sampling Method-principle, for symptom assessment in IBS.
