NCT ID: NCT03919370 Not yet recruiting - Ischemic Stroke Clinical Trials

Detection of Cerebral Ischemia With Artificial Intelligence.

Start date: May 8, 2019
Study type: Observational

In patients undergoing planned surgery for carotid tromendarterendectomy, a non-invasive device that registers heart rate variability is attached. furthermore a non-invasive device that monitors cerebral oxygenation- near infrared spectroscopy is also attached. At times when surgeons clamps the carotid artery, there will be a moment with controlled cerebral ischemia. This will be registered by the devices. The information obtained will be used to teach artificial intelligence what patterns are related to cerebral ischemia. the same procedure will be performed in patients undergoing ocklusive cerebral trombectomy, so the artificial intelligence will learn to recognize cerebral reperfusion.

NCT ID: NCT03915782 Not yet recruiting - Stroke, Ischemic Clinical Trials

Neuroprotective Effect of Remote Ischemic Conditioning in Ischemic Stroke Treated With Mechanical Thrombectomy

Start date: July 1, 2019
Phase: N/A
Study type: Interventional

The benefit of mechanical thrombectomy in the treatment of ischemic stroke has been demonstrated in several multicenter randomized trials. However, it leads to a sudden reperfusion of the brain parenchyma associated to an extension of the infarct volume. Evidence has indicated that remote ischemic conditioning (RIC) reduces final infarct size in animal stroke models. The main objective of the present study is to determine whether remote ischemic conditioning can limit the final infarct volume after recanalization of the occluded cerebral artery.

NCT ID: NCT03915431 Not yet recruiting - Ischemic Stroke Clinical Trials

A Study of NCS-01 in Patients With Acute Ischemic Stroke

Start date: August 2019
Phase: Phase 1/Phase 2
Study type: Interventional

This is an initial Phase1/2 dose-finding, double-blind, placebo-controlled, multi-center study to evaluate the safety and tolerability of NCS-01 in patients with acute ischemic stroke. All patients will be randomized within 24 hours of stroke onset. This study will be conducted in 2 stages.

NCT ID: NCT03913221 Not yet recruiting - Clinical trials for Hypoxic-Ischemic Encephalopathy

Caffeine for Hypoxic-Ischemic Encephalopathy

Start date: June 2019
Phase: Phase 1
Study type: Interventional

Hypoxic-ischemic encephalopathy (HIE) due to perinatal asphyxia is common and often fatal. Therapeutic hypothermia reduces mortality and morbidity in infants with HIE. Even with the widespread use of therapeutic hypothermia, ~60% of infants with HIE die or have neurodevelopmental impairment. As a result, there is an urgent, unmet public health need to develop adjuvant therapies to improve survival and neurodevelopmental outcomes in this population. Caffeine may offer neuroprotection for infants with HIE by blocking adenosine receptors in the brain and reducing neuronal cell death. In animal models of HIE, caffeine reduces white matter brain injury. Drugs in the same class as caffeine (i.e., methylxanthines) have been shown to be protective against acute kidney injury in the setting of HIE. However, their safety and efficacy have not been studied in the setting of therapeutic hypothermia and their effect on neurological outcomes is not known. Since these drugs reduce injury to the kidney in infants with HIE, they may also reduce injury to the brain. This phase I study will evaluate the pharmacokinetics, safety, and preliminary effectiveness of caffeine as an adjuvant therapy to improve neurodevelopmental outcomes in infants with HIE.

NCT ID: NCT03910062 Not yet recruiting - Cardiac Arrest Clinical Trials

Lower Limb Surveillance During VA-ECLS: Evaluation of Angiography Through the Reperfusion Cannula at VA-ECMO Implantation and of Near Infrared Spectroscopy (NIRS) Monitoring

Start date: April 2019
Study type: Observational

Temporary cardiac support by VA-ECLS can lead to lower limb ischemia. The aim of this study is to evaluate a multi-modal strategy (physical examination, NIRS monitoring and angiography through the reperfusion canula) of lower limb surveillance.

NCT ID: NCT03909581 Recruiting - Clinical trials for Coronary Artery Disease

EndoACAB vs PCI for LAD Revascularization

Start date: February 10, 2018
Phase: N/A
Study type: Interventional

The purpose of this study is to determine which treatment option is better for patients who have isolated coronary artery disease (blockages of one vessel supplying blood to the heart muscle). The treatment options compared in this study are: 1. Endoscopic coronary arterial bypass 2. Percutaneous Coronary Intervention. This study is aimed to determine the best treatment for patients with coronary artery disease.

NCT ID: NCT03909022 Active, not recruiting - Clinical trials for Peripheral Artery Disease

Assessing Best Medical Treatment Patterns of Patients With Symptomatic Peripheral Arterial Occlusive Disease in Germany

Start date: January 1, 2008
Study type: Observational

This proposed study will be conducted to support real-world-evidence on the extent of best medical treatment for secondary prevention of patients with symptomatic peripheral arterial occlusive disease (POAD) for prevention of worsening limb symptoms or of major adverse cardiovascular events. The overall objective of this study is to gain a better understanding of patient characteristics, treatment patterns and outcomes in POAD patients. For this purpose the investigators will analyze a patient population hospitalized either with intermittent claudication (IC) or chronic limb-threatening ischaemia (CLTI) while taking prior POAD-related diagnoses in the outpatient setting into account. In detail, we study differentials according to age, calendar time, sex, disease severity and hospital procedure. Data were extracted from available German health insurance claims.

NCT ID: NCT03907904 Not yet recruiting - Clinical trials for Brain Hypoxia Ischemia

Continuous, Non-invasive Monitoring of Intraoperative Cerebral Perfusion and Oxidative Metabolism (CPOM)

Start date: July 2019
Study type: Observational

This study uses a CPOM Optical neuromonitor to assess the relationship between brain cytochrome C oxidase, cerebral oxygen saturation and blood pressure during surgery performed under general anesthesia.

NCT ID: NCT03907891 Not yet recruiting - Physical Activity Clinical Trials

Reducing Hopelessness Through Enhanced Physical Activity in Adults With Ischemic Heart Disease

Start date: May 2019
Phase: N/A
Study type: Interventional

After a 30-year decline, heart disease is projected to increase up to 18% by 2030. Participation rates in cardiac rehabilitation remain extremely low and hopeless individuals are less likely to participate. This innovative study has the potential to advance science, improve patient care, and improve patient outcomes by demonstrating the effectiveness of the Heart Up! program to increase physical activity and reduce hopelessness in patients with heart disease. Hopelessness is associated with a 3.4 times increased risk of mortality or nonfatal myocardial infarction in patients with ischemic heart disease (IHD), independent of depression. Hopelessness has been identified in 27-52% of patients with IHD and can persist for up to 12 months after hospital discharge. Hopelessness, a negative outlook and sense of helplessness toward the future, can be a temporary response to an event (state) or a habitual outlook (trait). Hopelessness is associated with decreased physical functioning and lower physical activity (PA) levels in individuals with IHD. While research has investigated strategies to increase PA among IHD patients in general, the study team is the only group to design an intervention to promote PA specifically in hopeless IHD patients. The purpose of this randomized controlled trial is to establish the effectiveness of our 6-week mHealth intervention (Heart Up!) to promote increased PA in hopeless patients with IHD. A total of 225 hopeless IHD patients will be enrolled from a large community teaching hospital in the Midwest. Patients will be randomized (75 per group) to one of three groups: 1) motivational social support (MSS) from a nurse, 2) MSS from a nurse with additional significant other support (SOS), or 3) attention control (AC). It is hypothesized that 1) The MSS with SOS group will have the greatest increase in average minutes of moderate to vigorous PA per day at 8 and 24 weeks as compared to the MSS only or AC groups; 2) Greater increase in minutes of moderate to vigorous PA per day will be associated with decreased state hopelessness levels from baseline to weeks 8 and 24; and 3) Increased social support and increased motivation will mediate the effects of Heart Up! on a greater increase in moderate to vigorous PA at 8 and 24 weeks. The findings from this study could transform care for IHD patients who are hopeless by promoting self-management of important PA goals that can contribute to better health outcomes.

NCT ID: NCT03907293 Recruiting - Clinical trials for Coronary Artery Disease

Effect of a Cardiac Rehabilitation (CR) Programme on Molecular Mechanisms

Start date: February 23, 2019
Study type: Observational

This study will evaluate the effect of a cardiac rehabilitation (CR) programme on blood protein molecules that may improve the function of arteries in coronary artery disease (CAD) patients who have suffered a heart attack. CAD patients who have either agreed or disagreed to take part in a CR programme will be recruited. This will allow a comparison of the study measurements between a group of patients who complete a CR programme and a group of patients who do not. The other objective of this study is to perform interviews with the study participants and their significant others (i.e. spouse, family member, or a close friend) to listen to the reasons why patients agreed or disagreed to take part in a CR programme.
