NCT00066898
To assess the safety and efficacy of AGI-1067, as compared to placebo, in the treatment of vascular inflammation and atherosclerosis by assessing the reduction in cardiovascular events.
NCT00327691
The primary objective of this study is to determine the degree of additional reduction in cardiovascular risk that was accrued to patients by lowering their LDL-C beyond the currently accepted minimum target level for patients with pre-existing CHD. Secondary objectives include the safety profile of this treatment strategy, its cost-effectiveness, effect on other atherosclerotic-related events and procedures, and total mortality.
NCT00289302
Heart failure is a progressive disease that decreases the pumping action of the heart. This may cause a backup of fluid in the heart and may result in heart beat changes. When there are changes in the heart beat sometimes an implantable heart device is used to control the rate and rhythm of the heart beat. In certain heart failure cases, when the two lower chambers of the heart no longer beat in a coordinated manner, cardiac resynchronization therapy (CRT) may be prescribed. CRT is similar to a pacemaker. It is placed (implanted) under the skin of the upper chest. CRT is delivered as tiny electrical pulses to the right and left ventricles through three or four leads (soft insulated wires) that are inserted through the veins to the heart. People who have a dangerously fast heart beat, or whose heart is at risk of stopping beating, may be in need of an electronic device called an implantable cardioverter defibrillator (ICD). An ICD is implanted surgically just under the skin in the upper chest area and it sends a strong electrical impulse, or shock, to the heart to return it to a normal rhythm. If the heart is beating too slowly or at an abnormal rhythm, an ICD can also pace the heart to return the heart to its normal rhythm. The InSync ICD device can change the timing of when the left and right ventricles of the heart are paced to beat. The purpose of this study is to monitor the long-term performance of the InSync ICD Model 7272 and the InSync Marquis 7277 systems for cardiac resynchronization therapy (CRT).
NCT00115232
The purpose of this study is to evaluate levels of inflammatory mediators in children at risk for cardiovascular disease due to family history. We are measuring inflammatory markers in two groups of children and their parents: children with a family history of early atherosclerotic heart disease (cases), and healthy children without such a family history (controls). The design is a cross-sectional study, gathering a fasting blood sample and clinical and behavioral data on children and a parent.
NCT00048425
The purpose of this study is to evaluate the efficacy of a 24-hour infusion of levosimendan compared with placebo in the treatment of decompensated chronic heart failure.
NCT00013949
This project is part of a program project directed toward assessing cardiac effects of particulate and other ambient air pollutants. In this project active elderly adults living in the communities of Boston and Steubenville have attended 12 weekly sessions including approximately 40 minutes of Holter monitoring, blood pressure, and oximetry evaluation before, during, and after outdoor exercise. To investigate the relation of air pollution to cardiac and pulmonary rehabilitation, a second portion of this study involves abstraction of blood pressure and symptom data and downloading of available repeated measures telemetry data in two populations. These populations include: 1) 200 outpatients attending 8 to 36 repeated weekly exercise training sessions in a major hospital cardiac rehabilitation unit.
NCT00042081
The purpose of this study is to determine the efficacy of graft pretreatment with CGT003 (E2F Duplex Decoy), as compared to placebo, on the incidence of patients experiencing vein graft failure after coronary artery bypass surgery.
NCT00047775
A placebo-controlled trial of BiDil added to standard therapy in African-American patients with heart failure.
NCT00230724
Maintaining exercise participation among patients who have completed cardiac rehabilitation is integral to secondary prevention of coronary events and cardiac re-hospitalization. To promote exercise maintenance after completion of a 12 week Phase II rehabilitation program, we propose to offer a theoretically-based intervention that we have used successfully to promote exercise among older, primary-care patients. This program (Maintenance Counseling) includes brief advice from the Cardiac Rehabilitation case manager at Phase II program discharge followed by telephone-counseling based on the Transtheoretical Model of Behavior Change and Social Cognitive Theory. Health educators will provide the telephone-based intervention over 6 months. Using a randomized controlled design, 180 patients will be assigned to Maintenance Counseling or Brief Advice plus Contact Control. Outcome assessments will include an exercise tolerance test (baseline/post-rehabilitation and 6 months), self-reported exercise participation, motivational readiness for exercise, and objective activity monitoring at baseline, 6, 12 and 18 months.
NCT00200278
The objective of this study is to determine the differential effect of intervention delivery channel (phone versus print versus wait list control) on physical activity adoption and maintenance in previously sedentary adults. Both delivery channels have been found to be effective, but telephone-based interventions require more commitment on the part of the subjects and are more labor intensive than print-based interventions. Thus, we will conduct a randomized controlled clinical trial comparing three groups: 1) telephone-based motivationally-tailored individualized feedback; 2) print-based, motivationally-tailored individualized feedback; 3) minimal contact waiting list control condition (receive intervention after 12 months as controls). Two hundred and twenty-eight healthy, sedentary women and men ages 18-65 will be randomly assigned to one of the two interventions or the waiting-list control condition. Our primary hypothesis is that individuals randomized to either phone or print conditions will exhibit significantly higher levels of physical activity participation at 6 and 12 months than individuals in the waiting list control condition. And, in addition, that subjects randomized to the telephone condition will exhibit significantly higher levels of physical activity participation at 6 and 12 months than those in the print condition.
NCT00525954
The study will be conducted at up to 25 U.S. centers and will be a double-blind randomized parallel group placebo controlled study among subjects with stable coronary artery disease (CAD). Subjects will be randomized to receive either placebo tablets or one of 2 orally active doses of A-002. The duration of study drug therapy will be 8 weeks.
