Active clinical trials for "Hypertension"

The purpose of this study is to construct hypertension specialized cohort using uniform standards and specifications. This study timely collected multi-dimensional clinical information through electronic medical records, mobile health, data integration, informatics and computer modern techniques, linking self-reported data and big data platforms from different sources to timely obtain the incidence and mortality data, and integrating hypertension cohort samples and the associated clinical records systematically, in order to build a 30-thousand hypertension specialized cohort with fine phenotypic data and blood/urine samples, thus far to provide support for the development of precise medicine research and related industries.

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.

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.

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.

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.

Central blood pressure and pulse wave velocity were measured using a BR 102 Plus PWA device in perioperative time after kidney transplantation

Hypertension is the most important risk factor for cardiovascular and cerebrovascular diseases，and also a substantial public health problem. The purpose of the study is to investigate the association between plasma biomarkers and adverse outcomes in patients with 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.

Investigating neural respiratory drive by examining parasternal EMG measurements in patients presenting for assessment of presumed 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.
