Filter by:The purpose of this study is to test the hypothesis that isosorbide mononitrate prevents deterioration of renal function in patients receiving anti-angiogenic therapies that target vascular endothelial growth factor (VEGF).
The aim of this study is to evaluate the efficacy of a combination of Continuous Positive Airway Pressure (CPAP) and a Mandibular Advancement Device (MAD) on nocturnal Blood Pressure control in hypertensive patients in obstructive sleep apnea low CPAP compliers (less than 4 hours per night). Hypertensive patients demonstrating low CPAP adherence will be selected during a screening visit; they will be then randomized to one of the three following arms: Education to CPAP ("CPAP only"), Treatment by a MAD ("MAD only") or a combination of both CPAP and MAD ("CPAP+MAD"). Mean systolic, diastolic, diurnal and nocturnal blood pressure will be assessed during 24-h Ambulatory Blood Pressure monitoring, before and after a 3-month treatment intervention. Biological laboratory parameters, patients reported outcomes (daytime sleepiness and Quality of Life), will also be evaluated before and after 3 months of treatment.
Aortic stenosis (AS) is the most frequent valvulopathy in Western countries. The prevalence of AS is constantly increasing due to the aging of the population. Several studies have shown that pulmonary arterial hypertension (PAH) was common in AS patients referred for TAVI and that it was an independent predictor of mortality after TAVI. Currently, there is no data in the literature regarding the evolution and prognosis value of PAH measured using right heart catheterization (reference method). PAH could either regress after TAVI or continue to progress despite the treatment of valvulopathy, resulting in a refractory right heart failure that can lead to death. The hypothesis of this study is that patients with PAH before TAVI procedure and at the 3-month follow-up visit (PAH persistence) have an increased risk of cardiovascular mortality compared to patients with no PAH at 3 months or having a significant reduction of their PAH (PAH regression). The aim of the study is to evaluate the prognostic impact of the evolution of PAH after TAVI in 424 patients using right heart catheterization.
In this pilot RCT, a total of 40 adults with hypertension will be randomized to either an artificial intelligence (AI) physical activity intervention group or an active control group with a 1 to 1 ratio after completing a 2-week run-in period and 4-week training. The AI intervention group will receive an automated and personalized daily step goal intervention involving a sophisticated activity analytics algorithm using advanced statistics and machine learning, while the active control group will receive a standardized and fixed 10,000 daily steps goal. Both groups will receive an identical smartphone app (app content differs between the two groups) and ActiGraph GT9X Link to assess objectively measured physical activity (primary outcome) during the study period.
This study will compare different exercise training protocols on health parameters of postmenopausal women. The hypothesis is that short duration high intensity interval training will promote different effects of long duration moderate intensity training.
Oral selexipag is commercially available in several countries for the treatment of a particular group of pulmonary hypertension (PH) called pulmonary arterial hypertension (PAH). The aim of the present study is to investigate whether selexipag could be helpful to treat patients with another form of PH called sarcoidosis-associated pulmonary hypertension (SAPH).
This is an exploratory Phase 2a, randomized, double-blind, placebo-controlled, parallel-group, multicenter study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamic effects of RVT-1201 in patients with pulmonary arterial hypertension (PAH).
The investigators propose to leverage new technology using the Qardio app for iPhone and Android devices to automatically upload blood pressures, using a well-validated blue tooth blood pressure monitor (QardioArm), directly into the Duke electronic health record system (EPIC). Further, the investigators propose to develop an automated EHR (electronic health record) messaging system utilizing the home blood pressures that will be sent to the participant's PCP, with copies to the participant and the primary oncologist. This is a 12-week prospective non-randomized implementation study. 40 patients who are 18-74 years old who fall under the following criteria will be screened: 10 women with Stage 1-III breast cancer who are receiving either an anthracycleine of antiHER2 therapy, 10 men with prostate cancer on ADT, 10 individuals with CLL on ibrutinib therapy, and 10 individuals who are hematopoietic stem cell transplantation (HSCT) survivors. In Phase 1 (Weeks 1-4) of the study, participants will self-monitor their blood pressure using the QardioArm wireless upper arm blood pressure monitor 3 times per week. In Phase 2 (Weeks 5-12), the investigators will implement the auto-messaging system triggered by an abnormal weekly average systolic or diastolic blood pressure. The investigators will adapt the conceptual framework of Muldoon and colleagues whereby home blood pressure monitoring is combined with office blood pressures to optimize data for the primary care provider's clinical decision making. {Participants will be asked to complete a paper survey, upon enrollment, that will include life chaos and medication adherence questions. There will also be an end-of-study feedback survey (usability and acceptability questions through REDCap) for both the participants and their primary care providers. This is an implementation study with a descriptive analysis. The data generated from the study will be used in future studies, including testing of different interventions aimed at optimizing blood pressure control among patients on active cancer therapy. This study presents no greater than minimal risk to the subjects and adverse events are not anticipated.
Acute and chronic hemodynamic dose-response and safety evaluation of LIQ861 in PAH subjects.
The purpose of this study is to understand if administration of a personalized dose of the anti-hypertensive medication, labetalol, based on patient's history of preexisting hypertension, will be more effective at controlling severe hypertension during pregnancy, compared to the current standard dosing.
