The International Imaging Registry in Liver Cirrhosis (BAVENO-VI SPSS GROUP).

Liver CirrhosisPortal Hypertension1 more

The purpose of this study is to perform a multicentre registry of cirrhotic patients who had been submitted to an imagining technique in recent years (angio-CT scan or abdominal MRI), in order to collect anatomical and clinical information. The main objective will be focused on the study of portosystemic shunts and their relation with portal hypertension. Patient with liver cirrhosis submitted to an abdominal angio-CT scan or a MRI from year 2010 to 2014 will be included in the study. The chosen imaging technique will be angio-CT preferably, but MRI data will also be available. Patients will be identified in every hospital by means of the registry of coded diagnoses and the lists of complementary tests performed. Clinical and radiological data of every patient will be collected. The clinical variables will be obtained from reviewing the patient clinical history. The radiological parameters will be gathered by means of the systematic review of the angio-CT or MRI.

Catestatin and Hypertension in Pregnancy

Pre-EclampsiaEclampsia3 more

Catestatin is a kind of protein involved with cardiovascular disease. Accumulated evidence shows that Catestatin may be a predictor of primary hypertension, but whether it plays the same role in pregnant hypertensive disorders needs to be determined. By measuring the plasma level of Catestatin, main biochemical marks and UCG in healthy pregnancy and pregnancy with hypertension, the research may contribute to this problem.

Registry for Chronic Obstructive Pulmonary Disease With Pulmonary Hypertension in China

COPDPulmonary Hypertension

Pulmonary hypertension is a common complication of chronic obstructive pulmonary disease (COPD). It is reported that over half of COPD patients develop pulmonary hypertension. COPD and pulmonary hypertension may have pathological or genetics interactions so that patients having both disorders tend to have poor prognosis. Echocardiography is widely used to detect pulmonary hypertension, but it's not accurate enough. Therefore, high-quality data reflecting the prevalence, disease course and outcome of pulmonary hypertension in COPD is very limited in China. The aim of the study is to detect pulmonary hypertension with right heart catheterization, describe its outcome in Chinese COPD patients and explore the underlying interaction mechanism.

Abdominal Compartment Syndrome : Diagnostic and Prognostic Value of CT Findings - a Prospective...

Intra-Abdominal HypertensionAbdominal Compartment Syndrome

Abdominal Compartment Syndrome (ACS) is a well known condition occuring in critically ill patients in intensive care units. This syndrome features a sustained intra abdominal hypertension (IAH) above 20 mmHg and a multiple organ failure due to the raise of the intra abdominal pressure. Several reviews described CT findings linked to these conditions, but most of them suffer an insufficient statistical method. Furthermore, the main CT feature described as specific in ACS, Round Belly Sign (RBS), has been highly debated since. This study is aimed to evaluate, in a prospective way, the diagnostic and prognostic value of CT findings in abdominal hypertension and abdominal compartment syndrome patients hosted in intensive care units, based on previous reviews and adding three new CT features described for the first time.

The Chinese Early-onset Hypertension Study (CHESS)

Hypertension

Hypertension (HTN) is the most important cardiovascular risk factor which is responsible for 50% of cardiovascular morbidity and mortality, and also a substantial public health problem affecting approximately 1/4 of the adult population in industrialized societies and over 1 billion people worldwide. Chronically elevated blood pressure without well control puts people at increased risk of target organ damages, including stroke, myocardial infarction, congestive heart failure, end-stage renal disease, blindness, and death. Especially, these damages are dramatically more severe in the early-onset hypertensive population.

Collection of Anonymised Blood Pressure Data During High Risk Surgery

Perioperative Hypertension

This is a single centre, prospective, non-randomised clinical investigation to be undertaken at the Queen Elizabeth Hospital, Edgbaston, Birmingham. The clinical investigation will collect fully anonymised perioperative blood pressure data from patients undergoing elective high risk surgery. The Sponsor of this clinical investigation, Directed Systems Limited, is developing a new medical device, BP Assist, which provides guidance to anaesthetists in relation to the real-time management of patient cardiovascular physiology.

Differential Diagnosis of Pulmonary Hypertension With Automated Image Analysis

Pulmonary Hypertension

The aim of the study is to determine relevant morphologic parameters of the lung vasculature for the differentiation between different groups of patients with pulmonary hypertension (PH) by thoracic computer tomography (CT). In this pilot study patients undergoing right heart catheterization will be investigated by thoracic CT and special software to determine morphologic readouts. The investigators expect that using this non-invasive method, parameters relevant for the differentiation of the patients with PH can be determined.
