Active clinical trials for "Hypertension"

In the 2016's Haute Autorité de Santé (HAS) recommendations (Haute Autorité de Santé. Management of arterial hypertension in adults. Saint-Denis La Plaine: HAS; 2016.) concerning the management of arterial hypertension in adults, the Ambulatory Blood Pressure Measurement (ABPM) is described as a diagnostic tool for hypertension as well as a tool useful for checking blood pressure (BP) control in treated patients. It is also stipulated that ABPM can provide additional information such as the exploration of significant blood pressure variability. The 2014's ESH recommendations (ESH practical guidelines for ambulatory blood pressure monitoring, 2014) concerning ABPM indicate that variability of BP over 24 hours can be considered as a research parameter. Blood Pressure Variability could be a better predictor of organ damage related to hypertension than blood pressure measured in consultation. Furthermore, BP measurement over 24 hours has been demonstrated as a more sensitive risk factor for cardiovascular events such as stroke or ischemic coronary events. It is specified in the 2018 ESH/ESC guidelines on the management of hypertension (Mancia G, et al. 2018 ESC/ESH Guidelines for the management of arterial hypertension. 2018) that an additional number of ABPM parameters may have prognostic value such as 24-hour variability even if there is no indication yet of its evaluation in clinical routine. The variability of blood pressure is associated with an increased risk of cardiovascular events, in particular stroke and coronary events in young and hypertensive patients, regardless of their cardiovascular risk factors, mean value of their systolic BP measured in ABPM or during consultation follow-up as shown by Rothwell PM et al. (Prognostic significance of visit-to-visit variability, maximum systolic blood pressure, and episodic hypertension. The Lancet. mars 2010;375(9718):895-905) and Mehlum MH et al. (Blood pressure variability and risk of cardiovascular events and death in patients with hypertension and different baseline risks. Eur Heart J. 21 juin 2018;39(24):2243-51.) Studies also show that BP variability in elderly hypertensive patients is an independent risk factor for cardiovascular events (Eto M et al. Impact of Blood Pressure Variability on Cardiovascular Events in Elderly Patients with Hypertension. Hypertens Res. 2005;28(1):1-7.) and that BP variability would be greater in the elderly patient (Magdás A et al. Ambulatory monitoring derived blood pressure variability and cardiovascular risk factors in elderly hypertensive patients. Biomed Mater Eng. 2014;24(6):2563-9) Finally, a link between frailty and blood pressure variability is demonstrated by Rouch L et al. (Visit-to-Visit Blood Pressure Variability and Incident Frailty in Older Adults. Le Couteur D, éditeur. J Gerontol Ser A. 13 juill 2021;76(8):1369-75.) However, BP variability, measured in this study by blood pressure variation between clinical visits, does not assess overnight variability. Another limitation in the evaluation of frailty is the exclusion of patients with an MMSE < 24. Hussain SM et al. (Variation in Mean Arterial Pressure Increases Falls Risk in Elderly Physically Frail and Prefrail Individuals Treated With Antihypertensive Medication. Hypertension. sept 2022;79(9):2051-61.) also show that BP variability measured by ABPM would increase the risk of serious falls in frail or pre-frail elderly subjects taking antihypertensive treatment. The objective of this study is therefore to evaluate the link between blood pressure variability on 24-hour recordings measured by the standard deviation and the coefficient of variation, according to the frailty status in patients aged over 75 with hypertension, treated or not with antihypertensive molecules.

Pulmonary hypertension (PH) is a pathophysiological condition defined by an increase in pulmonary arterial pressure above 20mmHg, which encompasses many very dissimilar conditions. Right ventricular function is the major determinant of survival in these patients. Currently, right ventricular function is estimated by trans-thoracic echocardiography via the measurement of standardised parameters. However, cardiac magnetic resonance imaging is now the reference technique for non-invasive quantification of volumes, mass, function of the right ventricle but can also be useful for the consideration of the pulmonary circulation. Thus, indices of function can be extracted and it plays an increasing role in the prognostic evaluation of the right heart function at diagnosis and at re-evaluation under treatment of pulmonary arterial hypertension. This work will initially focus on the assessment of right ventricular myocardial work by echocardiography and cardiac magnetic resonance imaging in comparison with invasive haemodynamic data.

Pulmonary Hypertension (PH) is a rare disease that makes patients easily become breathless. There is evidence that people with PH can benefit from exercise; we want to look at how they can access rehabilitation in their local community. Aim: To see if it is feasible to study physiotherapy well-being reviews in PH. Step 1: We will interview some patients with PH who have had rehabilitation and ask questions about their experiences. We will also ask what they think we should measure to show any difference their rehabilitation has made to them. The findings from Step 1 will help us to shape the details of Step 2, where we will conduct a small study to see if it is feasible to run a full study. Participants will be divided randomly into a treatment group and a control group. The treatment group will have a physiotherapy well-being review, leading to referral to their most suitable local rehabilitation service and follow-up after 6 months. The control group will receive brief exercise advice and follow-up after 6 months. The findings will help to design a full study and be shared with patients and health professionals.

Patients in for treatment of benign intracranial hypertension will undergo two tests that are not routinely performed for these patients: central corneal thickness and axial length of the eye. The data obtained from these measurements will be assessed to see if the correlate with aspects of vision loss including visual acuity, visual field status, optical coherence tomography (OCT) results, and fundus photographs.

The purpose of this study is to determine if dynamic hyperinflation seen in patients with idiopathic pulmonary artery hypertension (iPAH) improves with albuterol therapy.

The purpose of the study is to find out if taking a dose of gabapentin 600 mg by mouth (po) before surgery will help prevent the development of tourniquet pain and hypertension while the tourniquet is inflated during orif of tibia fracture.

The purpose of this study is to evaluate IOP response to experimental dose of Latanoprost- PPDS in subjects with ocular hypertension or open-angle glaucoma.

Pulmonary Arterial Hypertension (PAH) in the setting of Idiopathic Pulmonary Fibrosis(IPF)is a risk factor for morbidity and mortality in the peri-lung transplant(LT) setting. Currently there is no significant data to support the use of pulmonary vasodilators for PAH in the setting of interstitial lung disease such as IPF. The majority of IPF patients have PAH either at rest or during exercise. The study hypothesis is that bosentan may improve morbidity and mortality in the peri-LT setting in both IPF cohorts with either resting or exercise PAH.

Monocentric cohort study, prospective, evaluating the variability of cardiac output measurement by resting and stress impedancemetry as a prognostic factor for Pulmonary Hypertension

This research study aims to identify the obstacles faced by specific demographic groups of hypertension patients during their engagement in clinical trials. The study will collect in-depth information from participants and identify common factors that impede their enrollment or successful completion of these trials. By examining data from various demographic perspectives, the study aims to identify patterns impacting future hypertension patients' experiences.
