Active clinical trials for "Hypertension"

This is a prospective, multi-center diagnostic trial conducted at 5 high-volume liver centers in China designed to determine the diagnostic performance of radiomics-based hepatic venous pressure gradient (rHVPG) (investigational technology) by CT angiography (CTA) for noninvasive assessment of the clinically significant portal hypertension (CSPH) in patients with cirrhosis. Direct hepatic venous pressure gradient (HVPG) measurement by means of catheterization of a hepatic vein with a balloon catheter is the gold-standard method to assess the presence of CSPH, which is defined as HVPG≥10 mmHg.

The investigators seek to increase medication adherence of subjects. The investigators will send mailings to customers of an insurance company, asking them to predict or commit to a certain level of behavior. The investigators will measure whether this increases medication adherence.

Test the feasibility of performing worksite screening of Hypertension, Diabetes and Hyperlipidemia for six months

The objectives of the current study are to identify and evaluate new prognostic non-invasive and serological markers in patients with pulmonary hypertension. The focus will be on L-arginine metabolism and to clarify its influence on endothelial function.

The aim of the PRAM study was to determine whether women diagnosed with hypertension in pregnancy, using the traditional mercury device, have the same pregnancy outcomes when blood pressure is measured by either an automated device or a mercury device throughout the pregnancy.

This study will evaluate methodologies for measuring pedal edema associated with calcium channel blockers in middle-aged and elderly subjects and patients with hypertension.

Extubation and emergence from anesthesia lead to systemic and cerebral hemodynamic changes that can cause cerebral edema and hemorrhage. The hemodynamic profile on emergence is more favorable if a laryngeal mask airway (LMA) is inserted before neurosurgical patients emerge from anesthesia. We aimed to compare the impact of awakening neurosurgery patients after insertion of a ProSeal LMA to replace the endotracheal tube (ETT).

An echocardiogram using Definity contrast can provide the same information as the standard right heart catheterization.

Using implantable loop recorder the investigators wish to detect atrial fibrillation in high risk patients and compare it to the results using conventional Holter monitoring. The hypothesis is that 10-15% of high risk patients have subclinical atrial fibrillation. The investigators want to detect those people so they can receive appropriate anticoagulation treatment. The patients will get a comprehensive workup including ecg, echocardiography and blood tests.

Pulmonary artery hypertension (PAH) is a chronic and progressive disease that affects 15 persons per million. Although current therapy has improve disease prognosis, PAH still has a poor survival, with a median survival of 2.8 years after diagnosis. In the last few years new key elements in PAH pathogenesis have been discovered, such as the role of metabolism in disease onset and progression. In fact, PAH pulmonary smooth muscle cells switch into a glycolytic phenotype which resembles the metabolism of cancer cells. The investigators hypothesis is that "fatty acid oxidation inhibition reverts the PAH adverse phenotype by restoring mitochondrial function and morphology, decreasing proliferation and restoring apoptosis susceptibility in pulmonary smooth muscle cells "
