Vascular Disease

This is a prospective, open- label, single arm, multicenter clinical trial to evaluate the safety and effectiveness of the Cordella PA Sensor System in NYHA Class III Heart Failure Patients compared to a Performance Goal (PG).

The overall goal of the DISCOVERY study is to better understand what factors contribute to changes in cognitive (i.e., thinking and memory) abilities in patients who experienced a stroke. The purpose of the study is to help doctors identify patients at risk for dementia (decline in memory, thinking and other mental abilities that significantly affects daily functioning) after their stroke so that future treatments may be developed to improve outcomes in stroke patients. For this study, a "stroke" is defined as either (1) an acute ischemic stroke (AIS, or blood clot in the brain), (2) an intracerebral hemorrhage (ICH, or bleeding in the brain), (3) or an aneurysmal subarachnoid hemorrhage (aSAH, or bleeding around the brain caused by an abnormal bulge in a blood vessel that bursts). The investigators hypothesize that: 1. The size, type and location of the stroke play an important role in recovery of thinking and memory abilities after stroke, and pre-existing indicators of brain health further determine the extent of this recovery. 2. Specific stroke events occurring in individuals with underlying genetic or biological risk factors can cause further declines in brain heath, leading to changes in thinking and memory abilities after stroke. 3. Studying thinking and memory alongside brain imaging and blood samples in patients who have had a stroke allows for earlier identification of declining brain health and development of individualized treatment plans to improve patient outcomes in the future.

This study will test the hypothesis that patients presenting within 8 hours of onset with cerebral ischemia in the setting of proximal large vessel occlusions (LVO) and low baseline NIHSS scores (0-5) will have better 90-day clinical outcomes (mRS distribution) with immediate mechanical thrombectomy (iMT) compared to initial medical management (iMM).

The purpose of this investigation is to examine the role of oxidative stress in aberrant microvascular function in otherwise healthy women with a history of GDM.

Women who develop preeclampsia during pregnancy are more likely to develop and die of cardiovascular disease later in life, even if they are otherwise healthy. The reason why this occurs is unclear but may be related to blood vessel damage and increased inflammation that occurs during the preeclamptic pregnancy and persists postpartum. The purpose of this investigation is to determine the mechanisms contributing to this lasting blood vessel damage and to test whether taking a medication that blocks angiotensin II receptors (losartan) decrease these negative effects in women who have had preeclampsia. Identification of these mechanisms and treatment strategies may lead to better clinical management,of cardiovascular disease risk in these women. In this study we use the blood vessels in the skin as a representative vascular bed. Using a minimally invasive technique (intradermal microdialysis for the local delivery of pharmaceutical agents) we examine the blood vessels in a nickle-sized area of the skin in women who have had preeclampsia. We make these measurements after the subjects take a placebo and after they take losartan (an angiotensin II receptor blocker) to test whether this treatment improves vascular function in these women. As a compliment to these measurements, we also draw blood from the subjects and isolate the inflammatory cells to test how sensitive their inflammatory responses are following the placebo and the losartan treatment.

A prospective, multicenter single-arm, open label study to evaluate the safety and effectiveness of the Neuroguard IEP System for the treatment of carotid artery stenosis in subjects at elevated risk for adverse events following carotid endarterectomy (CEA).

Stiffening of your blood vessels, particularly the large vessels from your heart (called the aorta and carotids) you age contributes to the development of cardiovascular disease (CVD) such as heart attack and stroke. Nerve activity from your brain to your body also increases with advancing age but it is unknown if this nerve activity contributes directly to the stiffening on your blood vessels in older adults in addition to high blood pressure. Therefore, successful completion of the proposed aims will have a significant clinical impact by identifying if nerve activity from your brain could be a novel target for therapies that would lower stiffness of the aorta and carotid arteries in older adults.

The SATURN trial aims to determine whether continuation vs. discontinuation of statin drugs after spontaneous lobar intracerebral hemorrhage (ICH) is the best strategy; and whether the decision to continue/discontinue statins should be influenced by an individual's Apolipoprotein-E (APOE) genotype. An MRI ancillary study (SATURN MRI), in a subset of SATURN participants , will evaluate the effects of continuation vs. discontinuation of statin drugs on hemorrhagic and ischemic MRI markers of cerebral small vessel disease, and whether the presence/burden of hemorrhagic markers (i.e. cerebral microbleeds and/or cortical superficial siderosis) on baseline MRI influences the risk of ICH recurrence on/off statin therapy.

This partially randomized phase III trial studies the side effects of inotuzumab ozogamicin and how well it works when given with frontline chemotherapy in treating patients with newly diagnosed B acute lymphoblastic leukemia. Monoclonal antibodies, such as inotuzumab ozogamicin, may block cancer growth in different ways by targeting certain cells. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving inotuzumab ozogamicin with chemotherapy may work better in treating young adults with B acute lymphoblastic leukemia.

Complete occlusion of the Internal carotid artery (ICA) by atherosclerotic disease (COICA) causes approximately 15%-25% of ischemic strokes in the carotid artery distribution. Patients treated with medical therapy have a 7%-10% risk of recurrent stroke per year for any stroke and a 5%-8% risk per year for ipsilateral ischemic stroke during the first 2 years after ICA occlusion. Internal carotid artery occlusion causes an estimated 61,000 first-ever strokes per year in the US an incidence more than twice the annual occurrence of ruptured intracranial aneurysms Additionally, 40% of subjects with COICA who present with transient ischemic attack (TIA) and 70% of COICA who present with stroke have cognitive decline with increased risk of vascular dementia and Alzheimer's' disease (AD) with time (2,3). Symptomatic COICA subjects are at increased risk of developing cognitive impairment and progressive development of vascular dementia and AD with time. Our proposal leverages several compelling retrospective and prospective preliminary data from human to perform this exploratory trial with go/no-go criteria to proceed to a phase 3 based on the data generated
