The development of portal hypertension is a vital event in the natural progression of cirrhosis and is associated with severe complications including gastroesophageal varices bleeding. Cirrhotic patients with hemorrhagic shock and/or liver failure caused by variceal bleeding face a mortality of 5-20%. Hepatic venous pressure gradient (HVPG) is the recommended golden standard for portal pressure assessment globally with favorable consistency and repeatability. Reducing the HVPG to levels of 12mmHg or below is associated with protection of variceal hemorrhage. An HVPG> 16mmHg indicates a higher risk of death and HVPG ≥ 20mmHg predicts failure to control bleeding, early rebleeding, and death during acute variceal hemorrhage. The management of portal hypertension has showed a trend of diversification with the development of medication, endoscopy, radiological intervention and liver transplantation. Although medication and endoscopic therapy have achieved preferable effects and are recommended as standard of care for the prevention of variceal rebleeding, patients with HVPG≥ 16mmHg still have a high risk of treatment failure and a high rate of rebleeding. Recent years, early TIPS is recommended as the first-line therapy for the prevention of rebleeding in cirrhotic patients with HVPG≥ 20mmHg. However, for those with HVPG values between 16 to 20mmHg, there is still lack of strong evidence to demonstrate the best practice for the management. With the rapid advancement of laparoscopic device and technique, the utility of laparoscopic splenectomy and pericardial devascularization showed less surgical trauma, bleeding and complications while retaining dependable effects compared to traditional open surgery, especially for portal hypertension with hypersplenism. In the study, the investigators aim to conduct a multicenter randomized controlled trial to compare the safety and effectiveness of HVPG-guided (16 to 20mmHg) laparoscopic versus endoscopic therapy for variceal rebleeding in patients with portal hypertension.
Evaluate the cardiovascular and metabolic properties of MANP in subjects with HTN and MS according to rs5068 genotypes
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.
High blood pressure (HBP) is a major modifiable cardiovascular risk factor which prevalence is gradually increasing. Reducing blood pressure (BP) significantly decreases cardiovascular morbi-mortality. Nevertheless, BP control remains insufficient: only 51% of French patients using antihypertensive drugs achieve the BP control targets. HBP is mostly diagnosed and managed in primary care. Nevertheless, office BP measurements are unreliable for BP control and poorer predict target organ damage. Ambulatory BP measurements are recommended for HBP diagnosis and follow-up. 24-hour ambulatory blood pressure monitoring (ABPM) is the most cost-effective strategy. Its superiority has been demonstrated for HBP diagnosis and cardiovascular prognosis. In France, ABPM is poorly available and little studied in primary care. Therefore, the investigators conducted a regional prospective study to analyze the feasibility and benefits of ABPM among primary care hypertensive patients in daily practice.
Whole blood sample procurement study from pregnant women with signs and symptoms of Preeclampsia.
Clinically significant portal hypertension (CSPH) is associated with an incremental risk of esophageal varices and overt clinical decompensations in cirrhosis. However, hepatic venous pressure gradient (HVPG) measurement, the gold standard for defining CSPH (HVPG≥ 10mmHg) is invasive and therefore not suitable for routine clinical practice. This is a multi-center diagnostic trial conducted at 10 high-volume liver centres in China designed to determine the accuracy of deep learning Radiomics of MR imaging (investigational technology) for noninvasive detection of a CSPH in patients with cirrhosis. Transjugular 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.
HyperEcho is a multi-centre longitudinal observational study, to investigate whether baseline transthoracic echocardiography along with routine data collected in the hypertension clinic can guide clinicians to better manage, and improve risk stratification for cardiovascular disease in young adults with hypertension. Participants are characterised as young adult patients aged between 18 to 40 years old and referred to the hypertension clinic to manage their blood pressure. The study visit will be carried out during the planned routine visit of the participants to the hypertension clinics of NHS trusts within England. Routine data will be collected by the assigned nurse for the hypertension clinic as part of the clinical service, and research participation will not affect the clinical progress of the participant. The additional research component to the clinic will be asking the participants for their consent to undergo a research echocardiography scan if it has not been a part of their clinical assessment. Participants will also be asked to consent to the use of their data that has been collected in the hypertension clinic, such as; referral letters, medical history, 24-hour blood pressure monitoring report, ECG, blood samples, body fat composition, and dietary questionnaire. In addition to this, participants will be asked to consent to further review of their data and medical notes during their follow up visits (up to 10 years).
As one of the most common chronic diseases,The adult prevalence of hypertension is approximately 26.4% at present and will rise to 29.2% by 2025.Renal sympathetic denervation from the intima of renal artery has emerged as a potential treatment for resistant hypertension. However, renal sympathetic nerve are mainly located in the adventitia,and there is no report on renal sympathetic denervation from the adventitia of renal artery.This study is a multicenter,randomized,single-blind study,and aimed to observe the safety and efficacy of radiofrequency ablation of the renal artery from the adventitia on the basis of laparoscopic techniques for patients with resistant hypertension.
The purpose of this double blind randomized study is the evaluation of the safety and efficacy of the Moderato System. The Moderato implantable pulse generator is indicated for patients who have hypertension and also require a dual chamber pacemaker in order to reduce their blood pressure. In this amended CS-03 protocol Version 3.0, the study will evaluate the safety and efficacy in a randomized, double-blind study following active treatment vs. a control patient population for a period of 3 month for efficacy and 12 months for safety (In comparison to 6 months for patients under protocol CS-03 Ver 1.1, NCT02837445). The device will be considered to have a clinical effectiveness with regard to its anti-hypertension function if there is a statistically significant and clinically meaningful reduction in mean 24-hour ambulatory systolic blood pressure in the treatment group compared to the control group. The primary efficacy endpoint will be evaluated 3 months after randomization. The Primary safety analysis will compare the treatment and the control after 12 months of treatment.
Obstructive sleep apnea (OSA) is a common clinical condition, involving the development of arterial hypertension. A Meta analysis study have shown that isometric hand grip training promotes blood pressure reduction. It is going to be conducted a clinical trail to determine the effects of hand grip training in OSA patients to change the arterial hypertension.
