Filter by:A cholesterol/lipid profile screening project of high risk patients with hyperlipidaemia (secondary prevention) who already receive cholesterol-lowering therapy. Lipid profile and rate of patients who are treated to target (which is <100mg/dl for patients with high risk and <70mg/dl for patients at very high risk) are screened (office-based specialists). The doctors therapy decisions after the screening and possible reasons for these decisions will be documented. Our aim is to evaluate dosing habits, to evaluate how many patients are treated to their LDL-C target and to underline the importance of treating patients to their cholesterol targets.

The primary focus of the trial is safety and efficacy of the intra-muscular implantation of either bone-marrow, or peripheral blood mononuclear cells, in critical limb ischemia, as judged by the proportion of patients which are alive without major amputation 6 months after inclusion.
This is a multi-center, non-randomized, single arm study to compare PTA and primary stenting using a single PROTÉGÉ® EverFlex™ stent to performance goals of PTA alone in the treatment of atherosclerotic superficial femoral artery (SFA) and proximal popliteal lesions.
The study is designed to determine whether vorapaxar, when added to the existing standard of care (SOC) for preventing heart attack and stroke (eg, aspirin, clopidogrel) in participants with a known history of atherosclerosis, will yield additional benefit over the existing standard of care without vorapaxar in preventing heart attack and stroke. The study is also designed to assess risk of bleeding with vorapaxar added to the standard of care versus the standard of care alone.
Study title: A Study of Blood-Borne Autologous Angiogenic Cell Precursors Therapy in Patients with Critical Limb Ischemia ( ACPs-CLI ) Principle Investigator: Assoc.Prof. Pramook Mutirangura,M.D. Head of Division of Vascular Surgery , Department of Surgery, Faculty of Medicine Siriraj Hospital , Mahidol University, BKK,Thailand Study objective : To determine the safety and efficacy of intramuscular injection of blood-borne autologous ACPs in relieving symptoms of critical limb ischemia of patients treated with maximal medical therapy and don't have intravascular or operative revascularization option. Study Design : A pilot study , a single center, a non-randomized, open-label trial. Total expected no. of patients : 6 main selection criteria : A. Subjects will have one or more clinical indications diagnostic of CLI such as: distal extremity pain at rest that requires the subject to use analgesics for >2 weeks; or peripheral ischemic ulcer(s); or areas of gangrene ; or non-healing ischemic ulcers AND B. Subjects will have one or more of the following hemodynamic indicators of severe peripheral arterial occlusive disease: I. Ankle brachial index < 0.45 II. Toe brachial index < 0.35 III. TcPO2 / TcO2 of < 40 mmHg. C. The subject is a poor candidate for standard revascularization treatment for peripheral arterial disease, based on inadequate bypass conduit, or unfavorable anatomy D. Age 18 to 80 years Investigational Product : At D-8 250 ml of blood drawn from the patients for production of autologous EPCs or ACPs (VescellTM). On D0 ,at least 1.5 million ACPs with viability >75 % suspended in 30 ml sterile cell culture medium will be injected 1.5 cm deep and 1.5 apart by a 23 -gauge needle into the gastrocnemius muscle of the leg chosen (ischemic leg) for treatment. For injection planning a grid of 10X10 cm will be prepared and in each point 1 ml of ACPs suspension will be injected. The study consists of 4 periods: Screening ( D-14 to-9& D-8,Treatment(D0),Acute Safety follow-up (D1&D2),Chronic follow-up (D30 & D90)period ,total follow-up of each case is 3 months. Evaluation criteria : Safety : no.& duration of adverse event & serious adverse event Efficacy :Attenuate CLI patients symptoms (Rest pain,Pain-free walking distance,Ulcer size &Gangrene dimension and intensity)
Peripheral arterial disease (PAD) is a disease in which fatty build-up, or "plaque," accumulates in the peripheral arteries. People with PAD often experience leg pain while walking due to reduced blood flow to the legs. This study will use magnetic resonance imaging (MRI) techniques to examine how specific features of plaque build-up in the leg arteries affect walking ability, leg strength, and balance in people with PAD.
The purpose of this study is to validate the screening potential of NT-proBNP for the identification of patients scheduled for vascular surgery who would benefit from additional pre-operative cardiac testing. All patients will have NT-proBNP concentrations measured pre-operatively. For low-intermediate risk patients only those with abnormal values will receive further cardiac testing; all high risk patients will be referred for additional testing.
The purpose of this research study is to determine if the transplant of a combination of stem cells obtained from the bone marrow of the same patient will contribute to the formation of new blood vessels in the severely diseased ischemic limb (leg). In this study the safe use of this combination of stem cells and its effects on making new blood vessels will be evaluated. Limb Ischemia (LI) is a severe obstruction of the arteries which seriously decreases blood flow to the extremities (mainly feet and legs) and has progressed to the point of severe pain and even skin ulcers or sores. LI needs comprehensive treatment since the condition will not improve on its own. The overall goal of treatment is to reduce the pain and increase blood flow to improve symptoms or save the leg or feet. In many cases, current options for treatment including medications, surgery or endovascular procedures have not been successful. In the last few years, investigators have explored therapies aimed to increase blood flow to the ischemic vessels by transplanting cells that will promote the development of new vessels in the diseased leg. The study hypothesis is based on the concept that the process of formation of new blood vessels is complex and requires the participation of several types of stem cells and growth factors. The lack of any of these components will produce vessels which are immature and unable to provide appropriate blood supply to the leg. Patients eligible to participate in this study are those suffering from poor circulation or severe leg blockages, which are not candidates for surgical procedures. Once the mixture of stem cells is prepared and the patient's bone marrow is ready, cells will be transplanted into the calf muscle of the diseased leg. Clinical studies to evaluate if the transplant works and is safe will be performed up to 1 year after cell transplant.
The purpose of this study is to investigate the prevention of Restenosis following Revascularization of the superficial Femoral Artery (SFA)
