Filter by:The primary purpose is to evaluate the impact of hypnosis coupled with MEOPA (Equimolar Mix-ture of Nitrogen Protoxide and Oxygen) on patient comfort when performing transoesophageal echocardiographies. Further studies on the use of MEOPA alone or the technique of hypnosis alone in the context of an TEE, would not be innovative in any way in view of previous studies or already in progress. However, service has led to perform TEEs several times by combining MEOPA and hypnosis. Doctors noted a clear reduction in induction time for hypnosis and satisfaction of the patient and operators. This association technique is very often used in pediatrics. According to one study, it seems that MEOPA increases the threshold of suggestibility and imagination. However suggestion and imagination are two essential notions of the hypnotic technique. To date, doctors have not found any other studies combining MEOPA and hypnosis for adults patients in the context of TEE. This leads to the following hypothesis: Is there a difference for the patient in terms of for the global management of pain and anxiety between an TEE performed under MEOPA with a standard support and TEE under MEOPA coupled with hypnosis with support standard? Secondary purposes are: 1. Compare patients' feelings / opinions: patients who have benefited from hypnosis associated with MEOPA versus patients who have been treated with MEOPA alone. 2. Compare patient stress: patients who have benefited from hypnosis associated with MEOPA versus patients who have benefited from MEOPA alone. 3. Compare the operators' feelings / opinions: procedures that have been performed under hypno-analgesia and MEOPA versus standard procedures under MEOPA alone. 4. Failed the TEE procedure
Coronary artery disease (CAD) pathophysiology involves endothelium-dependent (e.g. nitric oxide, acetylcholine) and -independent (e.g. adenosine) vascular dilation impairment, which have been demonstrated at the level of small coronary arteries, medium sized peripheral arteries and subcutaneous microcirculation. Oxygen supplementation, which is frequently overused in clinical settings, seems harmful in acute coronary syndromes and increases microvascular resistance in myocardial and subcutaneous microcirculation through alteration of endothelium-dependent and -independent dilation by an oxidative mechanism. Whether endothelial dysfunction, that is well documented at the level of cardiac microcirculation in CAD patients, is also present at the level of subcutaneous microcirculation is unknown. Also, unknown is whether an acute oxidative stress can be used to probe myocardial microcirculatory dysfunction at the level of subcutaneous microcirculation, which is an easily accessible vascular bed for an in vivo assessment of endothelial-dependent and-independent function. Alterations in cutaneous vascular signalling are evident early in the disease processes. Thus, studying subcutaneous circulation in patients with cardiovascular risk factors could provide vascular information early in CAD processes. This study will test the following 4 hypotheses: 1. Endothelial dysfunction observed at the level of microvascular cardiac arteries is readily present at the level of subcutaneous microcirculation in a given CAD patient. 2. An acute oxidative stress such as hyperoxia can be used to test myocardial microcirculatory dysfunction at the level of the more easily accessible subcutaneous microcirculation. 3. Subcutaneous microcirculation of CAD patients has a lesser vasodilatory response to acetylcholine or sodium nipride than matched healthy subjects. In addition, CAD patients are more prone to dermal vasoconstriction in response to oxygen compared to healthy subjects. 4. Taken that oxygen is still too often given in excess in most clinical settings, the aim of this study is to rule out possible pitfalls in coronary pressure and resistance determinations in CAD patients receiving unnecessary oxygen supplementation.
Older patients with co-morbidity are increasingly represented in interventional cardiology practice. They have been historically excluded from studies regarding the optimal management of NSTEACS. Though there are associated risks with invasive treatment, such patients likely derive the greatest absolute benefit from PCI. Small, though highly selective, studies suggest a routine invasive strategy may reduce the risk of recurrent myocardial infarction. The study aims to include, as far as possible, an 'all-comers' population of patients aged 80 and above to define the optimum amount of revascularization required to achieve good outcomes and satisfactory symptom relief for this challenging cohort of patients.
The aim of the study is to collect data from surface ECGs by using Holter ECG recordings from patients with different forms of diagnosed arrhythmias and/or specific ECG characteristics from heart diseases to support the development of new sensing and detection algorithms for implants.
This clinical trial is being done to see if giving surfactant (Curosurf®) will decrease the number of days that infants will need a breathing tube, decrease the days in the critical care unit and decrease the number of days needed in the hospital. The primary hypothesis for this study is that there will be fewer days needed on mechanical ventilation and improved lung compliance and pulmonary gas exchange.
This is an 8-week randomized controlled trial to help address health, resilience, and well-being. Participants are randomized into either a health education group or an arts-based health education group. Both groups will attend for 8 weeks and various study assessments will be conducted in order to measure the experience and impact of the program. Anyone 18 years and older with a chronic health condition (for example, diabetes, hypertension, congestive heart failure, chronic obstructive pulmonary disorder, asthma, weight, anxiety, depression, cardiac, arthritis, multiple sclerosis, and many more) are eligible to participate.
This observational study will follow participants who completed follow-up in the FOURIER OUTCOMES trial to evaluate the long-term effects of evolocumab treatment. Long-term post-trial (legacy) beneficial effects have been reported with statins, niacin, hypoglycemic therapy and fibrates. Whether similar effects are seen after LDL cholesterol (LDL-c) lowering by PCSK9 inhibition is currently unknown. Evolocumab therapy causes a profound reduction in LDL cholesterol of approximately 60%. Statins have shown legacy effects over 5 years post-trial, including a 7% reduction in total mortality in meta-analysis and 12% reduction in coronary mortality. It would therefore be hypothesized that additional effects beyond the trial period would be conferred by previous evolocumab treatment. It is also important to assess the long-term safety of prior evolocumab treatment.
The second stage operation towards single ventricle palliation is 'bidirectional cavopulmonary connection' (BCPC). The superior vena cava is connected to the pulmonary artery, diverting 'blue' blood from the upper body (including the brain) to the lungs. A successful BCPC requires sufficient and easy blood flow through the lungs. Alprostadil is the synthetic form of prostaglandin (hormone that causes dilation of blood vessels) and has been shown to increase blood flow in the brain hence increasing blood flow to the lungs after BCPC, potentially useful in managing children post BCPC with low flow to the lungs and thus poor oxygenation. This study propose to investigate acute effects of Alprostadil on different blood vessels after BCPC.
The primary purpose of this study is to evaluate the diagnostic performance of three methods for measuring right ventricular size and function including the Philips Novel RV quantification technologies (RV Heart Model volumetric analysis and Philips 2D strain) and the Upper Valley Right Ventricle Algorithm (UVRV) algorithm as compared to the gold standard of volumetric analysis via cardiac magnetic resonance imaging (CMR) in a broad patient population.
In this randomized controlled clinical trial, patients with moderate to severe mitral valve stenosis (MS) and atrial fibrillation (AF) will be enrolled into the study.Participants will be divided into two groups based on the anticoagulation regimen type. The intervention group will receive rivaroxaban and the control group will be given warfarin. All patients will be observed closely during a period of one year. Through the follow up, embolic events and hemorrhagic complications will be recorded in both groups. In addition, patients in both group will undergo a baseline magnetic resonance imaging (MRI) and an MRI after one-year follow up, by which the silent embolic events will be compared in both groups.
