Filter by:The EMINENT study is a prospective, multi-center study confirming the superior effectiveness of the ELUVIA stent versus Self-Expanding Bare Nitinol Stents in the treatment of lesions in the femoropopliteal arteries.
The aim of this study is to evaluate whether use of the echoclip device (an ultrasound transducer positioning device which can stabilize the involved part of the myocardium on the beating heart) facilitates imaging of coronary bypass anastomoses during coronary bypass surgery. A total of 100 low risk patients undergoing elective on-pump coronary bypass surgery will be included in the study in order to evaluate if the surgeons can visualize the coronary anastomoses before closure of the sternum. Ultrasonograpic pictures will be analyzed directly peroperatively and electronically post-operatively in order to evaluate if selected areas of the anastomoses can be visualized. Use of the echoclip devise will be considered a success if at least 80% of the anastomoses can be visualized.
A phase II,randomized,double-blind,multi-doses,positive drug parallel controlled,multi-center clinical trial to evaluate initially the efficacy and safety of alprostadil liposomes for injection in the treatment of atherosclerotic occlusive disease of the lower extremities.
In the present study, by evaluating the efficacy and safety of low intensity ultrasonic on ASO, to explore the noninvasive auxiliary treatment of ASO. 90 patients were randomly divided into 2 groups: A)control group, patients were given Conventional conservative treatment; B）treatment group, patients were given Conventional conservative treatment and low intensity ultrasonic treatment ; Treatments last for 4 weeks, three times a week, stimulation was given 8 minutes every time, location of treatment were lower limb ischemia area and its surrounding tissues; outcome indicators were recorded Before and 4 weeks after the trial, The Walking Impairment Questionnaire (WIQ), ankle brachial ratio, the farthest distance Walking, percutaneous tissue oxygen tension, tissue oxygenation index recovery time, local skin temperature, ultrasonic blood vessels, and muscle enzymes, hepatic and kidney function.
Adipose-derived regenerative cells (ADRC) will be extracted from lipoaspirate by enzymatic digestion. 10 mL of autologous ADRC suspension injected intramuscularly, close to the site of muscle injury. All patients will receive cell therapy. This is a single arm study with no control.
Arteriosclerosis is a degenerative and dysmetabolic disease of the arterial walls. It is known to be the principal cause of coronary artery disease (CAD). Arteriosclerosis has an impact on the entire vascularization including the microvascularization. The retina is a nervous tissue that is supported by microvascularization. Therefore, systemic diseases that affect the nervous or the cardiovascular system are susceptible to have manifestations in the retina. Retinal signs associated to the risks to develop CAD (qualitative appreciation; diameter and appearance of arterioles) have been suggested. A quantitative approach would strengthen the interpretation of these evaluations. The Metabolic Hyperspectral Retinal Camera (MHRC) - the experimental instrument - has the capacity to identify and quantify a variety of biomolecules specific to the retina and the optic nerve. The purpose of this pilot study is to determine if the MHRC has the capacity to detect a specific hyperspectral signature in the retinal arterioles of subjects suffering from arteriosclerosis.
Arterial calcification is an independent predictor of coronary events associated with a 3-4 fold increased risk of cardiovascular events. Currently, no effective intervention exists to reduce arterial calcification. However, recent studies showed that vitamin K may reduce ongoing calcium deposition in the arteries, and thereby inhibit arterial calcification. The primary objective is to determine if MK-7 supplementation leads to stabilization or attenuation of ongoing calcium deposition in the femoral artery as quantified by 18F-NaF PET/CT imaging in patients with type 2 diabetes and arterial disease.
This is a multi-center, investigator initiated study that will prospectively and retrospectively examine treatment strategies and outcomes of patients who underwent percutaneous coronary interventions (PCI). The goal of this multi-center, investigator initiated, registry is to collect information on treatment strategies and outcomes of consecutive patients undergoing laser-assisted PCI among various participating centers. The study is a purely observational, chart review study and involves retrieval and compiling of data based on clinically indicated procedures and follow-up clinical and procedural outcomes. The information collected will be used to determine the frequency of laser-assisted PCI performed at the participating sites and examine the procedural strategies utilized, and the procedural (both immediate and subsequent) outcomes.
The objective was to evaluate the efficacy and safety of combination of beraprost and aspirin for prevention of arteriosclerosis progress in type 2 diabetes mellitus patients.
The purpose of this study is to evaluate the incidence of late incomplete stent apposition (ISA) and un-coverage by optical coherence tomography (OCT) following everolimus-eluting stent (EES) with bioabsorbable polymer (SYNERGY™, Boston Scientific,Nattick, MA, USA) versus zotarolimus-eluting stent (ZES) with permanent polymer(Resolute Onyx™, Medtronic, Santa Rosa, CA, USA) implantation in patients with AMI at 12 months.
