Active clinical trials for "Hypertension"

The investigators want to explore the relationship between different configurations of hypertension and the incidence of cardiovascular events by the guidelines reference range and EMINCA recommended reference range. Then the investigators want to enroll twenty research centers and 2200 hypertensions were planned to be collected and followed up in the 12th, 24th, 36th and 48th months after being enrolled in this study. Physical examination, ECG examination, laboratory examination, echocardiography and carotid ultrasound should be taken when baseline and follow-up. Echocardiographic measurement parameters were analyzed and the relationship between the echocardiographic measurement parameters and cardiovascular events and prognosis of hypertension.

The RECONNECTIVE Registry is an observational single center study, focused on the subgroup of precapillary pulmonary hypertension related to connective tissue diseases. All patients will have hemodynamic confirmation by right heart catheterization and will be follow-up for at least 5 years from admission. All patients diagnosed with Group I Pulmonary Arterial Hypertension (PAH) associated with Connective Tissue Diseases (CTD) and Group IV Pulmonary Hypertension (PH) with CTD will be included. The purpose of the registry is to learn and understand the clinical outcomes and natural history of the pulmonary arterial hypertension in this subgroup of patients to improve the medical care and treatment.

According to international guidelines, Hepatic Venous Pressure Gradient is the gold standard technique for portal hypertension measurement, but it is invasive and poorly available. Currently, surveillance of oesophageal/gastric varices is performed by upper gastrointestinal endoscopy. More recently, non-invasive tools to estimate portal hypertension have been developed and, among them, ultrasound elastography has been proposed as a technique to stratify patient risk to have portal hypertension. Aim of this study is to evaluate the relationship between ultrasound evaluation (D-CEUS + elastography) and endoscopic parameters predictive of clinically significant portal hypertension in patients with liver cirrhosis.

The goal of this observational study is to see if there is a cyclical or exaggerated diurnal variation in aldosterone production in people with Primary Aldosteronism.

Portal hypertension contributed to the main complications of liver cirrhosis. Currently, hepatic venous pressure gradient (HVPG) was the reference standard for evaluating portal pressure in patients with cirrhosis. However, the practice of HVPG is limited to require the extensive experience and highly specialized centers. In recent years, non-invasive methods were proposed to predict the degree of cirrhotic portal hypertension. Liver stiffness is currently the most widely used method for noninvasive assessment of portal hypertension. The renewing Baveno VII recommended that liver stiffness ≥ 25 kPa by transient elastography is sufficient to identify clinically significant portal hypertension (specificity and positive predictive value > 90%). Although liver stiffness has a good predictive value for evaluation of clinically significant portal hypertension, it is difficult to apply in primary hospitals due to expensive equipment. Recently, a multicenter study has shown that artificial intelligence analysis based on ocular images can aid to screening and diagnosis hepatobiliary diseases. The patented technology of collecting and analyzing diagnostic images of Traditional Chinese Medicine (TCM) based on mobile phone terminals has been realized. This technology mainly includes image acquisition, quality control and analysis, and clinical information collection. Liver cirrhosis belongs to the diseases of bulging and accumulation in TCM, and the most common symptoms are the liver and gallbladder damp-heat and liver stagnation and spleen deficiency. The main contents of inspection diagnosis in TCM for liver disease include the images of the tongue, eye and palms. In our study, the patented technology of TCM based on artificial intelligence is applied to establish a precise evaluation model of traditional Chinese and western medicine for portal hypertension with cirrhosis by combining the macroscopic characteristics of images and microscopic pathological indicators.

Studying the ultrastructural and immunohistochemical characteristics of Telocytes from umbilical cord vessels wall in PE patients compared to control and its relation to severity of disease whether controlled or uncontrolled.

The Change Database is a prospective, observational multi-center disease registry, which will collect data on patients with chronic thromboembolic pulmonary hypertension (CTEPH) in China. The registry will run for approximately 5 years. It aims to illustrate the epidemiology, management and longterm outcomes of CTEPH.

Psychological distress (anxiety and depression) is common in and experienced differently by people living with long-term health conditions (LTCs). Being able to measure whether psychological distress is related to living with a LTC would allow researchers and clinicians to provide interventions specifically tailored to the challenges of living with a LTC and therefore provide the most appropriate support for these patients. Such a measure would also be useful in research to identify the presence of illness-related distress in different patient groups. This project will therefore create a new measure of illness-related distress that has applications for both research and clinical practice. This will involve the psychometric validation of the new illness-related distress measure to test how valid and reliable the measure is. The aim of the project is to provide initial validation of the Illness Related Distress Scale in a community sample, recruited through online platforms. The objective of the study is to gather initial validity and reliability data for the scale.

Patients with high blood pressure (hypertension) and chronic kidney disease are at an increased risk of developing heart disease and strokes. Part of this risk is due to changes in the structure and function of the blood vessels throughout the body. It is thought that reducing high blood pressure and treating chronic kidney disease improves the structure and function of blood vessels but information on this is limited. Optical coherence tomography (OCT) is a method of looking at the blood vessels at the back of the eye. It is a simple, quick and non-invasive test that you may have previously had during a visit to the optician. The purpose of the study is to ascertain whether OCT is able to detect changes in the eye's blood vessels in patients with hypertension and chronic kidney disease compared to healthy individuals and also to see if any differences seen improve with treatment.

The TEMPLAR project is an observational, cross-sectional, multicenter study involving several community pharmacies spread all over Italy. The aim of the project, the currently largest Italian ABPM Registry, is to analyze the 24-hour ABPMs performed in community pharmacies enabled for this service in accordance with the current Italian regulations, in order to evaluate the level of BP control in the community and to provide scientific evidence on the usefulness of a telehealth network involving the pharmacist for the screening and control of hypertension.
