Filter by:Peripheral arteriopathy disease (PAD) affects 1 million people in France. In its most advanced stage: chronic permanent ischemia also called critical ischemia, the prognosis of patients is burdened with a one-year mortality rate of 30%. Chronic permanent ischemia results from a lack of oxygen supply to the microcirculatory network, responsible for tissue death and the development of trophic disorders. In this context, many studies have focused on the contribution of hyperbaric oxygen therapy, however none demonstrates with certainty its beneficial effect with a heavy set-up for teams and patients. Furthermore, it appears that normobaric oxygen therapy could have its place in this context by temporarily restoring a sufficient level of transcutaneous oxygen. However, even if normobaric oxygen therapy is common practice although empirical for some practitioners, no data demonstrates its real interest. The purpose of this study is therefore to report the proportion, in usual practice, of patients with permanent chronic ischemia of the lower limb(s), benefiting from normobaric oxygen therapy, but also to show the interest of the contribution of this therapy in usual comprehensive management of these patients. This is a pilot study, after which, if the hypothesis is confirmed, it may be proposed to carry out a randomized study, on a large scale, in order to validate the use of normobaric oxygen therapy in the context of chronic permanent ischemia.
Vascular rehabilitation for arteriopathy of the lower limbs remains little known in France, despite its good results. There are very few rehabilitation centres, and they are overcrowded and expensive. Outpatient walking rehabilitation is under-used, despite recommendations (4). One of the difficulties is getting patients to adhere to the treatment sufficiently and for a long time. According to the Fédération Française de Musicothérapie (FFM), this is a care practice based on sound or musical mediation with the aim of supporting, accompanying or re-educating a patient. Music is used as a means of expression, communication, structuring and relational analysis.The benefits of music therapy for our bodies and our behavior are numerous, including improvements in cognitive functions (attention, memory), psychomotor functions (agility, mobility, coordination) and social-emotional functions (healthymind website 10/03/2021).
The purpose of this study is to evaluate the safety and tolerability of ascending doses (Part A) and selected doses (Part B) of BB-031 in acute ischemic stroke patients presenting within 24 hours of stroke onset. Participants will be randomized to receive one dose of either the investigational drug or placebo and will be followed for 90 days. A total of 156 patients are planned in this study.
The objective of this study is to examine the safety and effectiveness, from both clinical and technical perspectives, of utilizing the 5G-Robotic VRS100 system in percutaneous coronary intervention (PCI).
Current study will be undertaken to identify combinations of biomarkers that can reliably identify acute mesenteric ischaemia (AMI) and distinguish between non-transmural and transmural ischaemia. Different combinations of biomarkers for different sub-types and severity of AMI, and different time points of measurement after onset of symptoms.
The project is a multicenter, open-label, randomized medical experiment, which was designed to evaluate the efficacy and safety of single-stage pulmonary vein isolation (PVI) and implantation of left atrial appendage occluder (LAAO) in comparison with either isolated LAAO implantation or chronic therapy with non-vitamin K antagonists anticoagulants (NOAC) in patients with recent-onset ischemic stroke and atrial fibrillation (AF). Based on former randomized controlled trials, percutaneous implantation of LAAO was shown to be non-inferior to vitamin K antagonists (VKA), but according to guidelines the use of LAAO is recommended only in patients with absolute contraindication to chronic anticoagulation therapy. PVI constitutes an acknowledged rhythm control management strategy in patients with paroxysmal and persistent AF, which leads to symptomatic relief in about 60% of treated patients, however, its beneficial effect on long-term outcome was demonstrated only in patients with heart failure with reduced ejection fraction. The feasibility and compatibility of both interventions performed as a combined single-stage procedure are warranted by common vascular access via transseptal puncture, which may lead to reduction of procedural cost and shortened overall duration of both interventions. Taking into consideration the preliminary registry data, the combined single-stage PVI and LAAO implantation are thought to be a safe procedure in patients with a high risk of recurrent ischemic stroke and cardiovascular death. The study will comprise 240 patients who were diagnosed with ischemic stroke within preceding 6-12 weeks, with confirmed paroxysmal or persistent AF and low-to-moderate psychomotor dysfunction in the course of cerebral incident, who completed early neurological rehabilitation and are characterized by high risk of ischemic stroke recurrence (CHA2DS2-VASc score ≥2 pts in men; ≥3 pts in women) and who received adequate oral anticoagulation therapy (NOAC/VKA) for ≥4 weeks. After exclusion of thrombus and potential anatomical contraindications to the procedure on transesophageal echocardiography, patients will be randomized in 1:1:1 ratio to study group treated with combined single-stage PVI + LAAO implantation during 3-day hospitalization and to control group subject to LAAO implantation or control group subject to chronic therapy with NOAC. The duration of active enrollment phase will be 18 months. Subsequent follow-up phase will include scheduled outpatient visits (at 3, 12, 48 months) and phone call interview (at 6, 18, 24, 36 months) in order to evaluate the occurrence of clinical and safety endpoints, medical symptoms and signs, quality of life reflected by structured questionnaire, the presence of AF on 7-day Holter electrocardiography. Follow-up visits will also include blood laboratory tests analysis, including biomarkers of heart failure and left atrial wall stress, as well as transthoracic echocardiography with tissue Doppler imaging and strain imaging. In addition, patients in study group and control group treated with LAAO will attend additional outpatient visit at 6 weeks in order to perform transesophageal echocardiography so as to confirm procedural success and allow for termination of chronic anticoagulation therapy. Co-primary composite endpoint will comprise cardiovascular death, ischemic stroke, transient ischemic attack, systemic arterial embolism and major non-procedural bleeding, including intracranial bleeding (non-inferiority). The current project was based on the preliminary results of nonrandomized studies, which delivered evidence for feasibility of combined single-stage PVI and percutaneous left atrial appendage closure and laid ground for future randomized controlled trials. It is expected that the proposed intervention will be non-inferior in terms of composite cerebrovascular events and superior in terms of major nonprocedural bleeding in comparison to chronic NOAC therapy.
A prospective, multicenter, observational, single-arm trial to validate CardioFlux MCG's ability to diagnose myocardial ischemia caused by coronary microvascular dysfunction in patients with suspected ischemia and confirmed no obstructive coronary artery disease (suspected INOCA) by using diagnostic measures of coronary flow reserve (CFR) via invasive angiography as a reference standard for diagnosis.
The purpose of this study is to evaluate the safety and efficacy of Human Urinary Kallidinogenase combined with endovascular therapy in acute ischemic stroke (AIS) patients with large vessel occlusion.

The goal of this multi-center observational study is to learn about the effectiveness of magnetocardiography in rapid and accurate identification of ischemia in patients with suspected NSTE-ACS.
