Active clinical trials for "Hypertension"

This is a prospective, multi-center diagnostic trial conducted at 6 liver centers in China designed to study the correlation between serum biomarkers associated with endothelial dysfunction and immune inflammation and hepatic venous pressure gradient in cirrhosis.

Whole blood sample procurement study from pregnant women with signs and symptoms of Preeclampsia.

This retrospective study aimed to analyse the relationship between multi-exposure to noise and air pollution the onset of hypertension disorders during pregnancy It will be conducted in 2650 mothers who gave birth at Dijon or Besançon CHU between 2005 and 2009 split into two groups: 530 cases (women who experienced hypertension disorders during pregnancy 2120 controls (women who did not experience a hypertension disorder during pregnancy)

First, the aim of the study was to evaluate the usefulness of echocardiographic parameters for detecting pulmonary hypertension (PH) in patients with advanced lung disease referred for lung transplantation. Second, to assess the prevalence of PH and to identify which hemodynamic, echocardiographic, pulmonary functional test, exercise capacity and biochemical parameters (especially NT-proBNP) have an impact on survival in a cohort of patients with severe lung diseases referred for lung transplantation.

Due to a massive outbreak of violence against the Rohingya minority residing in the Rakhine State of Myanmar in late 2017, several hundred thousand Rohingya fled the country and sought a shelter in Bangladesh. Currently, in the refugee settlement areas east of the city of Cox's Bazar, close to 1 million Rohingya refugees live in refugee camps close to the municipalities of Ukhia and Shamlapur. According to previous examinations, there is a serious burden of non-communicable diseases in Bangladesh. But little is known about the health status and the epidemiology of non-communicable diseases in the Rohingya refugee population in Bangladesh. Most importantly, scientific evidence on non-communicable disease in humanitarian emergencies is rather limited. The aim of this study is to close this gap and to systematically assess the burden of hypertension and diabetes within the Rohingya refugee population in refugee camps in Bangladesh and in the host community in the Chittagong province. This assessment will help to design and to introduce community-based intervention strategies aiming to improve the population health status and reduce the disease burden.

With the appearance of the new SARS-COV2 virus, additional challenges are being imposed on the medical community after the resolution of acute COVID-19 illness, resulting in specific pathophysiologic mechanisms that while acutely damage the lung parenchyma might chronically impact the cardiopulmonary system. This study aims to investigate changes after mild COVID-19 illness in echocardiographic indices at rest and stress.

Norepinephrine is the vasopressor of choice for the treatment of peri-anesthetic arterial hypotension. The use of this drug at significantly lower concentrations (dilution factor between 40 and 200) than the commercial preparation is increasingly common in the operating room ("baby-noradrenaline"). In addition, dilution errors are potentially serious for the patient (hypertensive peak) The preparation of precise dilutions is an important factor for the safe use of this medically In this study, the investigators wish to compare the dilution method of the protocol with another method of preparation (left to the free choice of the participant).

Rectal varices (RVs) are an important cause of lower gastrointestinal bleed (LGIB) in portal hypertension (PHT) and have been reported to occur in 44% to 89% of cases of cirrhosis. RVs are dilated sub-mucosal porto-systemic communications which extend from mid rectum to the ano-rectal junction and are considered distinct from internal hemorrhoids, which are submucosal arterio-venous communications of the anorectal vascular plexus. The suspicion of RVs as the cause of bleeding can be made with a high index of suspicion when lower GI bleed is seen in absence of hemorrhoids, and colonoscopy shows blood in rectum. Bleeding usually happens from endoscopically evident rectal varices (EERV) but sometimes bleed can occur from varices, which are endoscopically in evident (EIERV). Endoscopic ultrasound (EUS) has been shown to be more sensitive in diagnosis of EIERV. Endoscopic and EUS correlation of RVs has shown that RVs, classified as tortuous, nodular, and tumorous on endoscopic examination, have corresponding appearances on rectal EUS as single, multiple, and innumerable submucosal veins, respectively. The hemodynamic evaluation (HDE) of RVs by EUS is routinely done at some centers to assess parameters like the site, size, velocity, or direction of flow.

The study aims to investigate the characteristics of subjects with hypertension at onset among a cohort of apparently healthy subjects, with overweight or obesity (BMI ≥ 25 Kg / m2), and free of any drug treatment at the baseline. The evaluation includes anthropometric (weight, height, BMI, waist circumference), haematochemical (hormones, metabolic and routine) parameters and the screening for hypertension with ABPM. The diagnosis of hypertension is made in accordance with the 2017 guidelines of the American College of Cardiology / American Heart Association ACC / AHA.

Ambulatory blood pressure monitoring (ABPM) is a major innovation in the history of hypertension diagnosis. In clinical practice, the most well established indication for using ABPM is to identify patients who have high BP readings in the office but normal readings during usual daily activities outside of this setting or vice versa, and to identify varying 24-h BP profiles. However, in recent years, there has been increasing interest in BP values during sleep, and nocturnal BP is now recognized to be superior to daytime BP in predicting fatal and nonfatal cardiovascular events (stroke, myocardial infarction, and cardiovascular death), especially in medicated patients. The current direction in the management of hypertension is toward earlier and lower BP control for 24 hours, including the nocturnal and morning periods. Therefore, it may be of great significance to pay attention to the management of nocturnal blood pressure so as to reduce the increased cardiovascular risks. Information of nocturnal hypertensive patients defined by ABPM was prospectively registered nationwide, and then to investigate whether there was difference in cardiovascular prognosis according to the control of ambulatory nocturnal blood pressure.
