Filter by:The main purposes of this study are: - to describe the prevalence and degree of reduced left ventricular function and hypertrophy in patients with peripheral arterial disease in comparison to controls from the general population, - to evaluate factors of importance to left ventricular dysfunction and hypertrophy in patients with peripheral arterial disease, and - to assess the impact of cardiac function and left ventricular hypertrophy on long-term prognosis in patients with peripheral artery disease.
Using autologous bone marrow mononuclear cells (BM-MNC) to treat patients with chronic limb ischemia has been proved safe and effective. However, processing bone marrow by Ficoll density gradient centrifugation is not only time consuming but also expensive. Manually processing of bone marrow also results in large variation in therapeutic cell quantity and quality which directly leads deviation of safety and efficacy of the cell therapy. This study is aiming to compare an automated bone marrow processing system with a conventional manual method in term of safety and efficacy.
To evaluate the safety and effectiveness of the Absolute Pro® Peripheral Self-Expanding Stent System and the Absolute Pro® LL Peripheral Self-Expanding Stent System for the treatment of subjects with atherosclerotic de novo or restenotic lesions in the native superficial femoral artery (SFA) and/or the native proximal popliteal artery (PPA). CAUTION: Absolute Pro® Peripheral Self-Expanding Stent System and the Absolute Pro® LL Peripheral Self-Expanding Stent Systems are investigational devices. Limited by Federal (U.S.) law to investigational use only.
The objective of this clinical evaluation is to evaluate the immediate and long term (up to 12 months) outcome of the XIENCE PRIME Everolimus Eluting Coronary Stent System (Abbott Vascular) in a controlled prospective investigation for the treatment of patients with critical limb ischemia due to the presence of lesions between 3cm and 10cm in length at the level of the below the knee arteries. Specifically the trial aims to illicit angiographic and ultrasound patency, clinical improvement, and adverse events associated with the use of this stent. The trial design is single armed, prospective, controlled trial run over 12 months of follow-up.
Peripheral Arterial Disease (PAD) is a highly prevalent public health problem that results from progressive atherosclerosis of arteries in the lower extremities. PAD is also associated with major detrimental effects on quality of life and functional status, and is the most important cause of limb amputation. More importantly, PAD is a major manifestation of cardiovascular disease and a potent predictor of myocardial infarction, stroke and death. Despite its frequent occurrence, little is known about the natural history of PAD in Hispanics who represent 12.5% of the United States. Because access to health care is limited among Hispanics, CBPR is the ideal process to reach this target population. The goal of the proposed study is to evaluate community-based strategies of detection and treatment of peripheral arterial disease (PAD) in Hispanics. The proposed project consists of two phases: a cross-sectional phase (PAD detection), followed by a randomization phase.During the PAD detection study , the prevalence and severity of PAD in this population will be determined. Specific risk factors associated with PAD among the Hispanic participants will be identified. During the second phase patients will be enrolled in a randomized, non-blinded trial comparing a community-based risk factor modification and supervised exercise program versus usual care for PAD. These individuals will undergo a baseline evaluation similar to the one obtained during the first phase of the study, but will also include functional testing of the lower extremities.
The scope of the JET registry to observe long term treatment effects of Jetstream Navitus on various lesions types/morphologies.
Cardiovascular risk functions fail to identify more than 50% of patients who develop cardiovascular disease. This is especially evident in the intermediate-risk patients in which clinical management becomes difficult. The purpose of this study is to analyze if ankle-brachial index (ABI), measures of arterial stiffness, postprandial glucose, glycosylated hemoglobin, self-measured blood pressure and presence of comorbidity are independently associated to incidence of vascular events and whether they can improve the predictive capacity of current risk equations in the intermediate-risk population.
Although microparticles have been well-documented as mediators of inflammation and coagulation in various cardio-vascular disease events, it is currently not known how Percutaneous Transluminal Angioplasty (PTA) for peripheral arterial disease influences microparticle numbers, phenotype and distribution pre- and post interventionally and how they are related to or affect the incidence of early re-stenosis - or if indeed they may be used to predict patients at risk of early re-stenosis.
This is a prospective multicenter registry to evaluate safety and performance of the REMEDY, biodegradable peripheral stent for the treatment of occluded or stenotic superficial femoral arteries. Patients will be followed for a period of 1 year.
Specific Aims: To delve into the complex phenomena of living with Peripheral Arterial Disease (PAD), and to investigate the patients' perspective of the factors that affects their decisions regarding management of their PAD. a) Utilize a qualitative approach to uncover factors that patients perceive support the management of their condition utilizing a purposive sampling of Peripheral Arterial Disease patients. 1. To determine what they believe to be effective tools to support themselves to improve their condition. 2. To determine from the patient's perspective if adherence to prescribed medical regimes are important for them to improve their PAD outcomes. 3. To describe the patient factors of those who are self reported adherent compared to those who are not or unable to their prescribed regimen.
