Active clinical trials for "Ischemia"

To conduct a series of five inter-related studies on acute cardiac ischemia (ACI) in women.

Primary objective of the MAAESTRO trial is to evaluate the impact of an educational and reminder-based intervention on the adherence of stroke patients to DOACs. Secondary objectives are to evaluate the association between non-adherence and clinical events, to identify predictors of non-adherence and to compare objective measures of adherence with self-reporting. Key methodological instrument for this study will be the "Time4Med" pillbox with Smart/ Reminder Card. The study includes 3 visits (baseline visit 0, follow-up visit 1 and end-of-study visit 2) with a total follow-up of 9 months. After an initial 3-month observational phase with electronic monitoring of adherence using the "Smart Card", all patients will receive counselling based on their electronically recorded drug intake data, as well as a multicompartment pillbox. Patients will be then randomised to one of two groups in a crossover design, so that in the subsequent 6-month interventional phase one group will use a (reminder-delivering) "Reminder Card" for the first 3 months and the "Smart Card" for the last 3 months, while the second group will use the cards in reverse order.

In Denmark, around 2 % of the population live with severe mental disease. People with severe mental disease live 15-20 years less than the general population. The majority of the years of life lost are a consequence of the excess mortality due to somatic disease. The high prevalence of somatic disease among people with severe mental disease can be largely attributed to physical inactivity, unhealthy diet and side effects from psychopharmacological drugs. Apart from the impacts of unhealthy lifestyle and medication side effects, research suggests that individuals with severe mental disease do not receive the same treatment for their somatic diseases as do the rest of the population. The inequality in diagnostics and treatment can be attributed to stigmatization from healthcare providers and patients' lacking awareness of symptoms and reluctance to seek medical care. Further, the increasing specialization within both somatic and psychiatric care has led to a division between these two treatment systems (8,9). Patients with severe mental disease who simultaneously have one or more somatic diseases need their treatment to be coordinated; such treatment should span general practice, the municipality and the psychiatric and somatic hospital. Accordingly, the following elements are necessary to create effective and coordinated treatment trajectories: detailed preparation, qualitative process evaluation as an integrated part of the courses of treatment, and involvement of all stakeholders from the start. The overall aim of the project is to optimize the detection of selected chronic somatic diseases, including cardiovascular disease (ischaemia and heart failure), diabetes, hypertension and high cholesterol, in individuals with schizophrenia, schizoaffective disorder or bipolar disorder; to initiate medical treatment; and to ensure treatment compliance among patients. Accordingly, the project has the following objectives: To develop an intervention targeting individuals with schizophrenia, schizoaffective disorder or bipolar disorder that can optimize the detection of selected chronic somatic diseases, including cardiovascular disease (ischaemia and heart failure), diabetes, hypertension and high cholesterol To test whether the developed intervention can optimize the detection of cardiovascular disease (ischaemia and heart failure), diabetes, hypertension and high cholesterol in individuals with schizophrenia, schizoaffective disorder or bipolar disorder The project's hypotheses are that an interdisciplinary and intersectoral intervention targeting individuals with schizophrenia, schizoaffective disorder or bipolar disorder can optimize detection of cardiovascular diseases (ischaemia and cardiac insufficiency), diabetes, hypertension and high cholesterol by systematic screening in general practice lead to initiation and maintenance of relevant medical treatment. Moreover, we hypothesize that the complete intervention in a long-term perspective will lead to decreased mortality within the target group.

Gastroschisis is one of the most common neonatal surgical conditions, and is increasing in incidence. Postnatal bowel ischemia leading to necrosis, bowel loss and short-bowel syndrome, occurs in a few instances, with significant impact. Intestinal gangrene occurs in up to 37%. The cause of the gangrene can be multifactorial. Contributing factors can be volvulus; venous engorgement with ensuing arterial compromise; constriction of the gut mesentery at the defect; and contribution of the hydrostatic effect of the column of bowel within a silo. Theoretically, the increased hydrostatic pressure incurred by the bowel in a preformed silo, may decrease blood flow to the apex of the bowel and contribute to ischemia. However, this does not seem to be the norm, as most cases do well in the silo. Cases of intestinal ischaemia within the silo have been described in patients. Any objective measure of bowel perfusion and therefore viability which can aid clinical assessment and management may benefit patient outcome. Near-infrared spectroscopy (NIRS) is used to noninvasively measure and monitor changes in the approximate regional haemoglobin oxygen saturation (SO2) in the blood. Measurement of oxygen saturation using NIRS is already in clinical application in other neonatal and paediatric medical and surgical diseases. NIRS has been recommended as a good trend indicator of changes in neonatal tissues oxygenation. NIRS-measured duration of cerebral oxygen desaturation is an accurate predictor of postoperative neurological injury in children undergoing cardiac surgery. The investigators propose to use NIRS to measure SO2 in the intestinal bed in patients with gastroschisis and to ascertain if there is any clinical advantage to routine monitoring in these patients. The aim of the study will be to: Measure Gastrointestinal SO2 (GSO2) of the bowel within the silo of gastroschisis patients Identify the clinical progress of patients with gastroschisis in the postnatal period Identify any association of the measured GSO2 with the clinical outcome and any gastrointestinal complications

The ECAD-CLI is an investigator-driven, prospective, single-center study. The aim of the study is to prospectively collect clinical, laboratory, angiographic, cellular and molecular variables related to prognosis and outcome in patients with diabetes mellitus and critical limb ischemia.

In the current study the investigators intend to evaluate the role of Ischemia modified albumin (IMA) in the prediction of poor outcome in patients with traumatic brain injury (TBI). The investigators hypothesize that IMA will be elevated in patients with traumatic brain injury due to the excessive production of reactive oxygen species by the injured brain.

This study builds, in part, upon preliminary results generated as part of the Pharmacogenomics Anti-Platelet Intervention (PAPI) Study (NCT00799396). The purpose of this investigation is to assess the impact of genetic variation in the carboxylesterase 1 (CES1) on response to clopidogrel as well as dual antiplatelet therapy (i.e. clopidogrel and aspirin), as assessed by ex vivo platelet aggregometry, in healthy Amish individuals. The investigators hypothesize that participants who carry alleles that modify the activity or expression of CES1 will have altered response to clopidogrel as well as dual antiplatelet therapy.

This is a randomized controlled trial designed to test an intervention (Remote ischemic preconditioning) in patients undergoing carotid endarterectomy (CEA).Remote ischemic preconditioning(RIPC) with transient upper limb ischemia/reperfusion is a novel, simple, cost-free,non-pharmacological and non-invasive strategy.The purpose of this study is to evaluate the effects of Remote Ischaemic Preconditioning on perioperative ischaemic injury in patients undergoing carotid endarterectomy compared to control intervention.The outcomes of interest include neurocognitive function,clinical outcomes,and biomarkers of brain injury.

This registry is a clinical post-market evaluation of the Genoss DES in subjects requiring coronary revascularization with Drug Eluting Stents (DES).

Background: CCTA is a common way to evaluate coronary artery disease. It stands for coronary computed tomography angiography. It uses scanning to look at the arteries that supply blood to the heart. It is noninvasive, widely available, and generally accurate. But it does expose people to radiation. Exposure to high amounts of radiation can increase a person s risk of getting cancer. Researchers want to learn more about the relationship between CCTA and radiation exposure. Objective: To see how much radiation is used to take pictures of the heart and how measures to reduce radiation are used around the world. Eligibility: People ages 18 years and older who need a computed tomography (CT) scan of the heart Design: Participants will be screened with a review of their medical records. Participants may have a pregnancy test. Participants will have the scheduled scan. Small, sticky discs will be placed on the chest. A small tube will be placed into a vein in the arm. A contrast material (dye) will be given through it. Participants will lie on the CT scanning table. A CCTA scan usually takes about 15 minutes if the heart rate is slow and steady.
