Filter by:In our clinical controlled trial, patients with coronary heart disease will be randomly assigned into the exercise intervention (low intensity resistance training with vascular occlusion) or usual physical activity group (control group).
In this study, typical cases of coronary heart disease are selected. They will be intervened by Xuesaitong soft capsules to investigate efficacy and safety for Coronary Heart disease.
Cardioplegic arrest is an essential part of cardiac surgery which aims to allow myocardial preservation and minimise myocardial swelling ,while providing a motionless and bloodless field ,.Blood cardioplegia has proven its efficacy for several decades and surgeons are still preferring to use it for myocardial protection of paediatric cardiac surgery ,although it is thought to be more time consuming since it is given with interrupted doses, . Even when advancement has came along the field of myocardial protection and cardioplegia solutions with the introduction of Bretschneider Histidine-Tryptophan-Ketoglutarate solution ,custodiol ,in 1970 ,which is given as a single dose and believed to be convenient, simple to deliver , and less time consuming . Many Surgeons haven't change their practice possibly due to paucity of studies comparing cardioplegia solutions in paediatric cardiac surgery and conflicting reports regarding the superiority of different cardioplegia solution.The investigators aim to provide evidence that will help paediatric cardiac surgeons to choose the optimal solution for their practice .
Evaluation of coronary artery vessel wall healing at different time points in patients undergoing implantion of bioresorbable vascular scaffold by using intravascular imaging. In addition long-term clinical follow-ups are planned for all patients treated with Absorb in the institution
Persistant hypoxemia in the newborn confers, even isolated, an abnormal clinical situation, that needs to be addressed for an adequate diagnosis and an optimal treatment. If during the first hours of life, hypoxemia is frequent and often transient, beyond that, it is necessary to search the various etiological conditions such as a critical congenital heart disease (CCHD) or a non cardiac affection (sepsis, anemia, respiratory disease). Newborn pulse oximetry screening identifies babies with critical congenital heart disease (CCHD) based on the rational that they frequently have a degree of hypoxemia that may be clinically undetectable. CCHDs are life-threatening forms of congenital heart disease (CHD) occuring in 2-3/1000 live births but accounting for 3%-7.5% of infant deaths. Early detection is beneficial because of acute collapse, if not resulting in death, is associated with a worse surgical and neurodevelopmental outcome. Currently, screening for CCHD involves antenatal ultrasound scanning and post-natal physical examination. Although antenatal detection rates have improved over recent years and can be as high as 70%-80% in some centers, this is not consistent. Indeed, in "Nouvelle Aquitaine" overall <50% of CCHDs are detected before birth. In addition, up to a third of infants with CCHD may be missed on post-natal examination. Pulse oximetry screening can help to close the "diagnostic gap' that is, increase the detection of babies who slip through the current screening net. Several large European studies and a subsequent meta-analysis have shown that pulse oximetry screening is a highly specific (99.9%) and moderately sensitive (76.5%) test which increases CCHD detection rates. The high specificity results in a low false-positive rate 0.05% to 0.5%. But those babies with a Positive Test, if they may not have CCHD, they may be diagnosed with other causes of hypoxemia (congenital pneumonia, sepsis, persistent pulmonary hypertension,...). As with CCHD, delayed recognition of these conditions can result in postnatal collapse and significant morbidity and mortality. It is also more useful to consider these conditions as secondary targets of screening and to remember they constitute 30%-70% of false positives. In 2011, the US Health and Human Services Secretary recommended that pulse oximetry screening for CCHD be added to the Recommended Uniform Screening Panel. In Europe, implementation is advanced in such countries as North European Countries, and Switzerland. There isn't yet any European guidance. In France, the implementation is limited to local and transient experiments. The feasibility, usefulness and cost-effectiveness of routine pulse oximetry screening have not been evaluated so far. The French setting has two specificities : 1/ the antenatal detection rate is considered to be rather high. 2/ in contrast to a lot of other European countries, early discharge from the maternity ward before 48 hours of life is not common, decreasing the risk of discharging a baby with undiagnosed CCHD, but not saving babies from collapse. - The Investigators hypothesis is that routine pulse oximetry screening in asymptomatic newborns would allow to reduce the incidence of complications related to CCHDs as well as those related to non cardiac pathologies for a reasonable cost for the French Health Care System.
This pilot randomized control trial will examine the role of choral singing on psychosocial stress and cardiovascular outcomes in patients with ischemic heart disease (IHD). The hypothesis is that choral singing will improve psychosocial stress in comparison to the control group and this may have an impact on rates of hospitalization, death, myocardial infarction and stroke in these patients.
Angina and heart attacks are caused by narrowings in the coronary arteries (blood vessels) supplying the heart. These narrowings can be opened using a balloon and stent (angioplasty). Traditionally, stents are constructed from metal and are permanent. However, newer stents are being constructed from carbohydrate polymers (scaffolds), which allow them to reabsorb over time leaving no permanent implant. New data has suggested that these scaffolds appear to reduce recurrent angina and may alter the blood flow down the artery. However, it is not known whether this is due to the scaffolds themselves or the way the scaffolds are inserted. In this study we hope to measure the blood flow to the heart and assess changes in that flow during stent and scaffold insertion. It is also important to know whether these effects are durable and thus, a cohort of patients will return at 3-months to be restudied. These data are important to help us understand why blood flow is affected by stent/scaffold selection or device implantation technique and whether this results in better long-term outcomes.
"Cardiovascular Imaging and Biomarker Analyses (CIBER)" is a single-center, prospective and observational study evaluating the expression of novel biomarkers in patients undergoing cardiacvascular imaging within clinical routine care. It is aimed to evaluate associations with biomarker expressions with ascertained cardiac imaging parameters.
In the landmark Boston Circulatory Arrest Study, neurologic and developmental status was measured following infant heart surgery and then prospectively at ages 1, 2.5, 4, 8, and 16 years, with findings of significant neurocognitive deficits and brain MRI abnormalities regardless of operative management. To date, no study has evaluated the neuropsychological and neuroimaging antecedents and correlates of well-being in adults with congenital heart disease, a population now >1 million and projected to grow at 5% per year. The investigators propose to study the Boston cohort at ages 24-29 years to assess the associations of adult well-being with childhood and adolescent executive function, other measures of mental health and cognitive function, adolescent brain MRI findings, and clinical variables; findings will guide the design of interventions in childhood to optimize outcomes in adults with congenital heart disease.
RITA-MI aims to develop of a novel therapeutic concept to target the immune response in patients with acute myocardial infarction (MI) by depleting B-cells with a single injection of Rituximab which is approved for clinical use in cancer, autoimmune disease and inflammatory conditions. The goal is to re-purpose the drug, and translate the discovery into benefit for patients at high risk of cardiovascular events. Rituximab is expected to limit infarction size and improve the healing process, as complementary to other therapeutic strategies. The applicants intend to perform a clinical study in patients with acute myocardial infarction (MI). The objective is to find the optimal dose (lowest dose with highest biological efficacy and best safety profile) for peripheral blood B cell depletion during the first 6 days after injection, and selective molecular signatures associated with improved heart function through analysis of peripheral blood samples. The study rationale is to decrease the inflammatory reaction upon tissue necrosis following heart muscle ischemia.
