Active clinical trials for "Hypertension"

This retrospective study aimed to analyse the relationship between multi-exposure to noise and air pollution the onset of hypertension disorders during pregnancy It will be conducted in 2650 mothers who gave birth at Dijon or Besançon CHU between 2005 and 2009 split into two groups: 530 cases (women who experienced hypertension disorders during pregnancy 2120 controls (women who did not experience a hypertension disorder during pregnancy)

First, the aim of the study was to evaluate the usefulness of echocardiographic parameters for detecting pulmonary hypertension (PH) in patients with advanced lung disease referred for lung transplantation. Second, to assess the prevalence of PH and to identify which hemodynamic, echocardiographic, pulmonary functional test, exercise capacity and biochemical parameters (especially NT-proBNP) have an impact on survival in a cohort of patients with severe lung diseases referred for lung transplantation.

Death from chronic liver disease has doubled in the UK over the last decade. This is largely due to the rise in liver disease from excess alcohol consumption, obesity related fatty liver disease and hepatitis B & C infections. The current 'liver tests' only identify liver injury when the damage is at an advanced stage. They neither estimate the degree of injury accurately nor help judge prognosis. The complications from chronic liver disease result mainly from raised pressures within the liver. We currently measure this pressure by passing a long catheter through the jugular vein in the neck into the liver. This invasive test does carry a small yet significant risk of complications and is not available outside specialised liver centres. Raised pressure within the liver is also associated with changes in the microorganisms within the gut. This leads to increased infective complications among patients with liver cirrhosis. We aim to noninvasively measure the pressures within the liver using Magnetic Resonance Imaging (MRI). We will recruit 49 patients with chronic liver disease who have had liver pressure measurements as part of their routine clinical assessment. The participants will attend the Biomedical Research Unit and the MR Centre for a single 2hour visit. We will also collect blood, urine and stool samples from them. The diagnostic accuracy of the quantitative MRI techniques will be validated against the pressures obtained via the invasive test. The quantitative MRI techniques will also correlated with biomarkers of liver injury obtained from blood and urine samples. The stool sample obtained will be used to characterise the gut microorganisms in these patients.

This quality improvement project is focused on improving hypertension care delivery processes in ambulatory clinical practices, 5 in Illinois and 5 in Maryland for a total of 10 practice sites.The primary aim of this quality improvement project is to improve blood pressure control among patients receiving routine care for hypertension in a diverse group of ambulatory clinical practices. A secondary aim is for American Medical Association (AMA) and Johns Hopkins Medicine (JHM) quality improvement staff to figure out the best way to help clinical practices in achieving improved blood pressure control, including working to increase the use of home blood pressure monitoring.

The incidence of chronic thromboembolic pulmonary hypertension (CTEPH) after acute pulmonary embolism ist not clear. It is estimated to be up to 3.8%. Prospective data registration does not exist. Treatment of choice is pulmonary endarterectomy if the thromboembolic lesions are surgically accessible. Otherwise interventional therapy by means of pulmonary balloon-angioplasty (BPA) or medical therapy is indicated. In Germany, the majority of the patients is referred to three CTEPH centers: Kerckhoff Clinic, Saarland University Hospital and Hannover Medical School to evaluate the therapeutic options. Starting in January 2016 all incident patients will be de-identified and included prospectively. Risk factors, outcome and treatment will be documented.

The aim of the study is to intensify the follow up of patients with pulmonary arterial hypertension via modern imaging guided methods in due consideration of the possibilities of three-dimensional echocardiography in order to optimize their specific therapy. The hypothesis is that the increased use of modern imaging guided tools is essential for the follow up.

This is a prospective comparison trial. Patients that will be included in the trial are those that will have operations in which their abdominal closure is temporary, i.e. patients sustaining trauma or septic abdomen. Patients will be grouped according to the method of temporarily abdominal closure (TAC) procedure: Vacuum-assisted closure (VAC) "Bogota bag" (BB), a sterile intravenous bag silo closure. The two methods are currently accepted with no clear cut evidence to prefer one on another. At Soroka Medical Center the decision to choose either of the methods is at the surgeon's discretion. Intra-abdominal pressure will be measured in all patients by the urinary bladder pressure technique at 6 12 24 ant 48 hours post operation. The measurement is a routine procedure done as part of the monitoring processes of critically ill patients in the General Intensive Care Unit (GICU). Patients will be evaluated for the development of acute intra abdominal hypertension with or without abdominal compartment syndrome.

This study aims to investigate in adolescents and young adults: the 24h diurnal variation of ambulatory central blood pressure the association of central compared to peripheral blood pressure with indices of asymptomatic target-organ damage

Guidelines recommend measuring end organ damage and in particular arterial stiffness in patients with hypertension. However, until now it was not possible to measure arterial stiffness with the use of simple methods. Recently, novel and innovative devices offering determination of arterial stiffness and central hemodynamics from simple and non-invasive arm cuff measurements have now become available. This study therefore evaluates the value of non-invasively measured arterial stiffness and central hemodynamics for guiding antihypertensive treatment in selected patient populations (i.e. elderly patients, patients with diabetes mellitus, patients with heart failure, and patients with resistant hypertension).

Pulmonary hypertension (PH) is defined as a group of diseases characterised by an elevated mean pulmonary artery pressure (Ppa) ≥25 mmHg at rest. Recently, chronic myeloproliferative diseases (CMPD) associated with pulmonary hypertension were included in the group 5 category, corresponding to PH for which the aetiology is unclear and/or multifactorial. CMPD include chronic myelogenous leukaemia, chronic neutrophilic leukaemia and chronic eosinophilic leukaemia (which primarily express a myeloid phenotype and polycythaemia vera), idiopathic myelofibrosis, and essential thrombocytosis in which erythroid or megakaryocytic hyperplasia predominates. The purpose of this research: Assess Prevalence of PH in patients with CMPD in Northern Israel Describe the demographics and clinical course in patients with CMPD who are diagnosed with PH.
