Filter by:Heart failure (HF) is a clinical syndrome caused by structural and/or functional cardiac abnormalities, resulting in a reduced cardiac output and/or elevated intra-cardiac pressures at rest or during stress. It is the leading cause of hospitalization in Internal Medicine departments. This study aims at exploring evidence of the importance of ultrasound in HF both for hospitalized patients and in the follow up. Ultrasound may be used as a recovery monitoring instrument at the bedside and also as a global cardiovascular assessment tool for these patients. HF represents an exciting opportunity to create an integrative ultrasound approach in Internal Medicine/Geriatric departments.The Authors plan a five-step ultrasound examination to evaluate and monitor HF patients during hospitalization and follow-up. They call this examination: the "ABCDE" score. It includes the evaluations of A, the Ankle-brachial index (ABI), B, the B-lines, C, the Carotid intima media thickness (CIMT), D, the Diameter of the abdominal aorta and of the inferior cave vein and E, the echocardiographic assessment of the ejection fraction.This score represent an integrative ultrasound approach in Internal Medicine/Geriatric departments.
Endovascular treatment is rapidly taking over surgery for aorto-iliac occlusive disease (AOID), also in extensive pathology. This is related to its minimally invasiveness, decreasing the procedural morbidity rate. When the aortic bifurcation was involved in the lesion, the patency rates of kissing stents configurations were often inferior to open repair. In 2013 the Covered Endovascular Reconstruction of the Aortic Bifurcation (CERAB) technique was introduced in an attempt to improve endovascular treatment results by a more anatomical and physiological reconstruction, with a subsequent improved clinical outcome. This investigator-initiated multicenter trial will prospectively record all data on performed CERAB procedures using the Bentley balloon expandable covered stents (BeGraft Aortic and BeGraft Peripheral) in multiple International sites, in order to gain more robust real-world data on the efficacy of these stent grafts for this indication. Consecutive patients in whom a CERAB will be performed with these particular covered stents in the participating centers. Main study parameters/endpoints: The primary end-point of this study is technical success. Patency rates, peri-procedural morbidity, clinical improvement, quality of life, clinically-driven target vessel revascularization and reintervention-rate will be secondary outcome measures. Overall, patients will be followed for 5 years
Background and purpose. Even if periprocedural cerebral microembolism associated with carotid endarterectomy or stenting usually does not manifest as clinically overt stroke, neuropsychological disturbances resulting from these events represent an important clinical and socioeconomic problem. Still, it remains unclear whether the use proximal protection can lower the incidence of cerebral embolism associated with the treatment of carotid stenosis. Materials and methods. This was a prospective randomised single-centre study, which was aimed at comparison of surgical eversion endarterectomy with stenting under proximal protection in symptomatic patients. The investigators evaluated the incidence of new ischaemic lesions revealed by the diffusion-weighted magnetic resonance imaging 2-4 days after the treatment and neurologic events.
Determining whether we could visualize uptake of the fluorescent tracer Bevacizumab-800CW, targeting VEGF-A in atherosclerotic plaques by using the new imaging technique Multispectral Optoacoustic Tomography both in- and ex vivo.
Intracranial atherosclerotic disease is the most common cause of ischemic stroke that is directly attributed to the progression or rupture of intracranial high-risk plaque in Asia. Many studies mainly from Euro-American population with a focus on extracranial carotid plaque have fully demonstrated the advantages of intensive statin therapy on stabilizing or reversing plaque burden, reversing plaque composition presenting that lipid-rich necrotic core (LRNC) is gradually replaced by fibrous tissue, and even reversing pattern of arterial remodeling to reduce the occurrence of cerebrovascular events. Yet, direct evidence of the effect of intensive statin therapy on intracranial atherosclerotic plaques is lacking and the effect of statin intensity and duration on intracranial plaque burden and composition is still unclear. High resolution magnetic resonance imaging (HRMRI) is a new and non-invasive technique that enable to assess the morphologic characteristics of vascular wall and plaque composition of intracranial artery. Based on above discussion, the investigators conduct this study to further determine the effect of intensive statin in ischemic stroke with intracranial atherosclerotic plaques.
A prospective, multi-center, single-arm registry to evaluate the safety and efficacy of bare metal stent-assisted percutaneous transluminal angioplasty (PTA) in the treatment of superficial femoral and/or proximal popliteal artery (P1) lesions in patients with symptomatic peripheral artery disease
To use a randomized controlled trial to test the effectiveness of four goal-setting strategies within a gamification intervention to increase physical activity among adults at elevated risk for ASCVD.
In this study researchers want to gain more information on treatment patterns of patients treated with Xarelto in combination with acetylsalicylic acid (ASA). Both drugs reduce the risk of blood clots via different pathways. The study will enroll adult patients suffering from coronary artery disease (narrowing or blockage of vessels that supply the heart with blood) or peripheral artery disease (narrowing or blockage of vessels that supply the legs or head with blood). The study will focus on information on when and why physicians are starting to treat patients with Xarelto in addition to ASA, treatment duration, reasons to discontinue treatment and previous therapies. The study will also look into treatment outcomes for patients being treated with a combination of Xarelto and ASA by their physicians.
Currently, the guideline recommended re-perfusion such as intravenous thrombolysis and mechanical thrombectomy as the most effective treatment for acute ischemic stroke. However, the two methods are restricted by a strict time window, which greatly limits the number of the patients receiving treatment. The abundant studies have suggested that good collateral circulation can provide compensatory blood supply to save the ischemic penumbra and reduces the infarct volume, which improves the prognosis. How to improve collateral circulation in an efficient and safe way is a clinical challenge. Our recent experiment results of the animal and preliminary clinical experiments show that head-down position may significantly increase cerebral perfusion and improve neurological function. Clinically, head-down position is simple and easy to operate, and theoretically may increases brain perfusion and improve collateral circulation. A pilot randomized clinical trial is designed to investigate the effect of head-down position combined with routine rehabilitation in patients with ischemic stroke.The study is designed to explore the efficacy and safety of head-down position in patients with acute ischemic stroke
