Active clinical trials for "Syndrome"

Vasovagal syncope (VVS, simple faint) is the most common cause of transient loss of consciousness and represents the acute episodic form of orthostatic intolerance (OI). Postural tachycardia syndrome (POTS) is the common chronic form of OI. Both are defined by debilitating symptoms and signs while upright relieved by recumbency. Northera should therefore improve both sympathetic splanchnic arterial vasoconstriction and sympathetic splanchnic venoconstriction in POTS and VVS, and may represent an ideal drug to improve the orthostatic response in POTS and VVS.

To test whether immediate complete revascularization is non-inferior to staged (but within six weeks after index procedure) complete revascularization in Patients presenting with ACS, including Non-ST-elevation ACS (NSTEACS) and ST-elevation myocardial infarction (STEMI), with multivessel disease accepted for PCI

Health organizations recommend exercise in an intensity based manner to promote cardiovascular adaptation and prevent disease. Metformin is a common anti-diabetes medication that reduces future type 2 diabetes and cardiovascular disease (CVD) risk. However, the optimal dose of exercise to be combined with metformin for vascular health remains unknown. The purpose of this study is to evaluate whether combining high or low intensity exercise with metformin has the potential to outperform either exercise intensity alone on blood flow across the arterial tree as well as impact insulin action in individuals with metabolic syndrome. Identification of such outcomes will indicate 1) whether and how metformin should be combined with physical activity for CVD prevention, 2) provide the first indication of whether exercise intensity reduces CVD risk via multi-level vasculature function vs. metabolic insulin action, and 3) provide a rational early treatment for people with metabolic syndrome to prevent/treat type 2 diabetes and CVD.

Coronary vascular dysfunction is one of the "final common pathways" for the impact of multiple cardiovascular risk factors. The investigators will conduct a randomized, double-blind placebo-controlled study in individuals with the metabolic syndrome and baseline coronary vascular dysfunction to evaluate the impact of vericiguat, a stimulator of soluble guanylyl cyclase, on coronary vascular function using non-invasive cardiac magnetic resonance imaging.

Walsdenström Macroglobulinemia (WM) is defined by a bone marrow lymphoplasmacytic infiltration and the presence of a monoclonal immunoglobulin M (IgM) in blood. Clinical manifestations of the hyperviscosity syndrome (HVS) are related to the large amount of IgM in circulating blood or to some physicochemical characteristics such as the presence of a cryoglobulin property. Although HVS is one of the most frequent criteria for initiating therapy in WM, few studies focused on its description and no diagnostic criteria are available. The present study aims to identify a diagnostic system for HVS, taking into account objective symptoms such as bleedings, fundoscopic findings and also subjective symptoms such as fatigue and comorbidities that may influence the severity of symptoms.

A common complaint among patients with Postural Tachycardia Syndrome (POTS) is "brain fog" or difficulty concentrating. This problem is poorly understood. The purpose of this study is to better understand the cognitive dysfunction associated POTS, and to determine optimal treatment strategies for this condition. In this study, the investigators will test the hypothesis that acute administration of the psychostimulant drug modafinil can improve seated measures of cognitive function in patients with POTS.

The primary objective of this study is to evaluate the impact of treating opioid use disorder (OUD) in pregnant women with extended-release buprenorphine (BUP-XR), compared to sublingual buprenorphine (BUP-SL), on mother and infant outcomes. The primary hypothesis is that the BUP-XR group will not have greater illicit opioid use than the BUP-SL group during pregnancy (non-inferiority).

The goal of this research is to prospectively evaluate the performance of the electromechanical window according to a phonographic method, as a mean of diagnosis of long QT syndrome, and to compare its performance with routine tests used.

The aim of this study is to establish, in a pilot RCT (approx. N=50 participants) with a time- and attention-matched health enhancement control, (a) the feasibility of the recruitment procedures (screening, eligibility, enrollment rates), and feasibility and acceptability of the (b) MBCT and control interventions (adherence, retention, fidelity, satisfaction, group videoconferencing delivery) and (c) data collection procedures by group (adherence, satisfaction). Hypothesis 1a: Recruitment will be feasible as evidenced by screening, eligibility, and enrollment rates; (1b) the MBCT and control interventions and (1c) data collection procedures in both groups will be feasible and acceptable.

The purpose of this trial is to conduct a pilot study that will aid in the design of an evaluation of the clinical benefit of MY01, an FDA cleared device, that allows continuous monitoring of intracompartmental muscle pressure in patients at risk for developing acute compartment syndrome. MY01 has previously been successfully tested on animal and Human cadaver Acute Compartment Syndrome models within the RI MUHC through Department of Defense research Grant (Combat Casualty Care Research Program (CCCRP). This trial is supported by the same grant, as the next phase of the overall project. This is a multi-center, non-randomized, historically controlled, prospective trial of the MY01 device. A cohort of 50 participants will be prospectively enrolled with two weeks follow up to document clinical benefit of the device. Results from this study will be used to inform the design of a larger study designed to demonstrate the clinical benefit of the MY01 device in the early diagnosis of ACS. The role of each organisation within the trial are detailed below: Research Institute of McGill University Health Centre (RI MUHC): study coordination and data analysis (no recruitment activity will take place in the MUHC).
