Filter by:More than 2 million patients in North America are treated with warfarin - a "blood thinner" - to prevent blood clots in arteries or veins. The treatment has to be monitored with a blood test and the dose changed accordingly every 1-4 weeks. One third of the patients have very stable results and hardly ever have to change the dose. The investigators wish to show that the level of control of the treatment with warfarin in these very stable patients is not worse with 12-weekly testing. A pilot study the investigators performed indicated that 12-weekly testing would be safe but this has to be confirmed in a large study. One third of patients taking warfarin have not had any changes in the dose for the past 6 months or longer. These patients will be asked about participation in the study. They will be randomized to testing and dosing every 4 or 12 weeks. Each patient is in the study until it ends, which will be minimum 1 year and can be up to about 4 years. The study is designed to show that 12-weekly testing does not significantly increase the risk for major bleeding or blood clots. The results would be important for a large number of patients. An increase of the interval between blood tests from 4 to 12 weeks would reduce the burden for these patients on life-long treatment considerably.
The nitinol stent has proven superior primary patency than balloon angioplasty in superficial femoral artery lesions. Recent stent design improvements focus on decreasing stent fracture rates which can negatively impact patency rates by rearranging strut alignment. In the literature, however, prospective, randomized, controlled, clinical trial for comparison of stent fracture and primary patency between different nitinol stents has never been performed except one study; SMART versus Luminexx stent named SuperSL trial. LifeStent is similar to S.M.A.R.T. stent in the design consisted of the peak-to-valley connected with S-shaped bridge but is different in lesser bridge (4 bridge vs. 6 bridge), large cell size on stent ends, and larger cell size than S.M.A.R.T. On the other hand, Recent meta-analysis has shown that the efficaty of cilostazol in the atherosclerotic femoropopliteal lesion was proven. However, still specific data regarding a variety of antiplatelet regimen in implanted femoropopliteal lesion are limited. Upto date, in the literature, never has never been performed the clinical trial for optimal duration of cilostazol use in the patient undergone stent implantation for femoropopliteal lesion. Thus, The purpose of our study is to examine and compare Primary patency and stent fracture between different two-nitinol stents (S.M.A.R.T. CONTROL versus Lifestent) in femoropopliteal arterial lesion and to examine and compare the optimal duration of cilostazol use.
The purpose of this study is to demonstrate the Safety and effectiveness of the use of NMB's drug ejecting balloon for the treatment of de novo and restenotic lesions in peripheral arterial disease.
The objective of IMPACT (Investigation of Motivational Interviewing and Prevention Consults to Achieve Cardiovascular Targets) is to determine the best management strategy for patients undergoing cardiovascular intervention. IMPACT is a prospective randomized trial that will enroll 400 patients post-cardiovascular intervention. The study will compare different cardiovascular prevention strategies: (1) usual care, (2) cardiovascular prevention consult, and (3) cardiovascular prevention consult with a behavioral intervention program over a 6-month period. The trial hypothesis is that for patients undergoing a cardiovascular intervention, a prevention consult and behavioral intervention is superior to usual care in reducing cardiovascular risk. The primary endpoint will be non-HDL cholesterol. Secondary endpoints include other lipid values, metabolic risk, smoking cessation, physical activity, nutritional status, medication adherence and quality of life. IMPACT is scheduled to begin enrollment in the June of 2012.
The study will compare Padd, a non-invasive automated optical device which uses a functional test to assess peripheral arterial disease (PAD), and Ankle brachial pressure index (ABPI) in the detection of PAD using as a gold standard, colour duplex ultrasound, in participants drawn from general practice, a hospital diabetic clinic and a tertiary vascular disease referral centre. The study hypothesis is that Padd performs at least as well as ABPI in detecting PAD.
The purpose of this study is to test the routine faisibility of a questionnaire to estimate walking impairment(The WELCH questionnaire) in patients investigated for suspected PAD.
The objective of this clinical study is to evaluate the immediate and long-term (up to 12 month) safety and effectiveness of a Nitinol Self-Expanding Paclitaxel-Eluting stent for the treatment of patients with critical limb ischemia (i.e. rest pain or non-healing foot ulcers) due to the presence of arterial lesions in the below-the-knee arteries of maximally 50mm long.
The purpose of the study is to collect additional safety and efficacy information on the Lutonix (formerly Moxy) Drug Coated Balloon for treatment of stenosis or occlusion of the femoral and popliteal arteries.
The peripheral arterial disease (PAD) is a common atherosclerotic disease manifestation and its prevalence increase with age and with the simultaneous presence of cardiovascular risk factors. PAD patients are usually treated, as a first line treatment, with the exercise therapy, combined with the pharmacological antiplatelet therapy. In the case of first line therapy failure, PAD patients usually undergoing to invasive revascularization procedures. After a peripheral stent has been located, the major follow-up problem is the restenosis rate. Published studies describe how, in a large amount of patients, can be recognised an high residual platelet activity. These data about PAD patients at the moment are lacking . The authors would evaluate the incidence of PAD patients with an high residual platelet activity.
The purpose of this study is to determine if it is safe and feasible to apply PRT-201 to the adventitia of arteries following successful angioplasty (PTA).
