Filter by:The objective of this study is to demonstrate that the investigational device, AngioDefender, is comparable to the established procedure referred to as 'brachial artery ultrasound imaging' in their abilities to quantify flow-mediated vasodilation of the brachial artery.
The purpose of this study is to assess the safety and efficacy of paclitaxel administration using the occlusion perfusion catheter (OPC) for the prevention of restenosis in infrainguinal de novo, restenotic femoropopliteal and infrapopliteal stenoses and occlusions, and in-stent restenosis.
Each patient who is admitted for preoperative preparation for elective open heart surgery at Intermountain Medical Center will be invited to participate in this study. After a written informed consent is obtained, patients meeting inclusion/exclusion criteria will be randomized 1:1 to the treatment arm or placebo/control arm. Those randomized to the treatment arm will receive three 50,000 unit oral doses of vitamin D3 supplementation. The first dose will be given the evening before surgery. The second and third doses will be given either orally or per NG tube on the mornings of post-op days 1 and 2. Blood will be obtained at the following time periods: 1) At baseline pre-procedure 12 to 18 hours before planned surgery; 2) Post-operative day 1, 12 to 24 hours after surgery; 3) 48 hours after surgery; 4) 72 hours after surgery; 5) At discharge (estimated to be between 5-8 days after surgery); and 6) At the 6-month follow-up visit (post-surgery). Plasma levels of 25(OH) vitamin D will be measured on each sample.
This study evaluates the impact of a supervised 12-week high-intensity aerobic interval exercise program (versus a self-directed exercise usual care group) on traditional and novel cardiovascular disease risk factors and surrogate markers of cardiovascular- and overall-mortality in a population-based sample of testicular cancer survivors.
The objective of this randomized controlled trial is to evaluate whether the investigators modernized IMPACT intervention for depression (eIMPACT), delivered before the onset of cardiovascular disease (CVD), reduces the risk of future CVD. Participants will be primary care patients who are depressed but do not have a history of CVD. Half of the participants will receive standard depression treatment in primary care (usual care), and the other half will receive one year of eIMPACT, a collaborative stepped care program including antidepressants and computerized and telephonic cognitive-behavioral therapy. To evaluate change in CVD risk, the investigators will measure artery function using ultrasound before and after the 1-year treatment period. It is hypothesized that patients who receive the eIMPACT intervention will have greater improvements in artery function than patients who receive usual care.
A single-center randomized trial at an academic medical center in Boston, Mass, of overweight or obese (body mass index: mean, 35; range, 27-42) adults aged 22 to 72 years with known hypertension, dyslipidemia, or fasting hyperglycemia. Participants were enrolled starting July 18, 2000, and randomized to 4 popular diet groups until January 24, 2002.
The purpose of this study is to conduct a prospective, multi-center, single arm, non-randomized evaluation of acute outcomes in Chinese subjects, including those eligible for percutaneous transluminal coronary angioplasty (PTCA) with a reference vessel diameter of 2.25 mm to 4.0 mm, with the Medtronic Resolute Integrity™ Zotarolimus-Eluting Coronary Stent System.
Longitudinal cohort study of older-aged people living with HIV infection in southwestern Uganda and age and gender-matched HIV uninfected controls with the primary aim of measuring the epidemiology of cardiovascular and pulmonary disease in this study setting, and particularly the contribution of HIV infection to it.
Stroke is one of the most frequent and life-threatening diseases in Europe. About four stroke events occur per day in Luxembourg alone, and about 30% of these patients are affected by recurrent stroke within the following five years. Thus, new methods of primary and secondary prevention are needed to better control lifestyle-related risk factors. The development and maintenance of a healthy lifestyle (smoking cessation, healthy nutrition, moderate physical exercises etc.) is a major objective concerning the primary and secondary prevention of cerebro- and cardiovascular diseases. CAPSYS is a computer-based lifestyle coaching system developed by researchers from the Public Research Centre (CRP) Henri Tudor in Luxembourg in collaboration with neurologists from the Centre Hospitalier de Luxembourg (CHL), which aims at supporting patients in performing appropriate behavior changes in order to minimize their individual risk factors. Patients can access CAPSYS by dialing a local-rate telephone number and answer to a set of previously known questions concerning their current nutrition, physical activity, blood pressure, smoking etc. In an interactive voice response approach, questions are issued by the system in natural language using text-to-speech, and the patient can provide the required values using the phone keypad. Based on the gathered values for each patient, the system automatically generates personalized verbal feedback at runtime and presents it to the patient during the phone dialog. Depending on the individual development of the patient's risk factors, the system feedback can contain advice for improvement, praise for healthy behavior and motivation to pursue a certain goal. The user acceptance and effectiveness of the CAPSYS system is evaluated in a six-month randomized controlled study with participants recruited at CHL's neurology department.
The study goal was to understand the effect of Metformin on Age/Sex/Gene Expression Score (ASGES) or Corus CAD (henceforth "Corus") in pre-diabetic patients who are medication naive. This study provided data to determine if the Corus CAD (ASGES) signature was different in pre-diabetic patients when metformin was newly prescribed and taken.
