NCT00831116
In April 2008, a coronary catheter based imaging system, LipiScan, was cleared by the FDA for use in detecting lipid core containing containing plaques of interest (LCP). These plaques are rich in cholesterol. The way that cholesterol and other lipids deposit with the coronary artery is unique to each patient. This study is an organized attempt to observe the LCP and the variety of ways that it presents in patients as detected by this recently approved device. This information will be used for physician training and to observe the behavior of the LCP in response to no therapy and currently approved therapies. The purpose of this project is further medical knowledge of the LCP and its treatment.
NCT00048308
During a heart bypass procedure, a substance called "complement" is released by the body. This complement causes inflammation, which can lead to side effects such as chest pain, heart attacks, heart failure, or impairment of memory, language and motor skills. The purpose of this study is to find out if the study drug (pexelizumab), which blocks complement release, can reduce such side effects and be taken safely.
NCT02638129
The purpose of this study is to evaluate cardiovascular (CV) safety of naltrexone hydrochloride (HCl) and bupropion HCl extended release combination (NB) compared with placebo and rule out excess risk of major adverse cardiovascular events (MACE) when given in combination with standard of care in overweight and obese participants with documented history of CV disease.
NCT00417625
This study will test the accuracy of magnetic resonance imaging (MRI) in measuring cardiac perfusion (blood flow). MRI of the heart can measure blood flow to heart muscle, but collateral coronary arteries (vessels that supply blood to the heart muscle) may reduce the accuracy of the measurements. This study will perform special measurements of coronary artery flow and pressure in patients undergoing heart catheterization and catheter-based treatment (angioplasty and stenting) in order to compare for accuracy with cardiac MRI. Patients 21 years of age and older with coronary artery blockage may be eligible for this study. All participants undergo cardiac MRI, to produce images of the heart, as well as special invasive blood flow testing during heart catheterization, angioplasty, and stenting. During MRI, the subject lies on a table that can slide in and out of the scanner (a narrow cylinder), wearing earplugs to muffle loud knocking and thumping sounds that occur during the scanning process. The procedure lasts about 45 to 90 minutes. Since the heart moves during breathing, subjects are asked to hold their breath intermittently for about 5-20 seconds. A medicine called dipyridamole is injected through a vein in the subject's arm to increase blood flow to the coronary arteries and help detect blockages. Pictures are taken of the heart before, during, and after the dipyridamole injection. Another medicine called gadolinium is also given through a vein. This medicine brightens the images to measure blood flow. During a separate catheterization, angioplasty, and stenting procedure, subjects undergo additional invasive tests. The additional tests use a special guidewire to measure coronary artery pressure and blood flow, as well as a special ultrasound to look inside the artery. Patients have a repeat MRI about 2 months after the catheterization.
NCT00308633
This study will measure blood levels of endothelial progenitor cells (EPCs) and nitric oxide (NO) in patients with coronary artery disease (CAD) who are participating in a 3-month cardiac rehabilitation program at Suburban Hospital in Bethesda, MD. EPCs are a kind of stem cell produced by the bone marrow that can develop into cells found in arteries and in the heart and, therefore, can repair diseased vessels. The study will examine whether the EPCs are affected by exercise and will look at how they may contribute to repair of cells lining the diseased arteries as a result of participation in the rehabilitation program. People with coronary artery disease may be eligible for this study. Candidates are screened with a medical history, physical examination, electrocardiogram, and blood tests. CAD patients also to a treadmill exercise test. Volunteers' participation ends at the screening visit. The blood drawn at screening is used to identify EPC specific genes to compare with the EPC genes from patients with CAD. CAD patients participate in Suburban Hospital's cardiac rehabilitation program. The exercise portion of the program includes 36 sessions of about 60 minutes each, spaced over approximately 3 months. Patients have a baseline blood test at screening and repeat blood tests at the end of each month of participation in the rehabilitation program. Some of the blood will be used for genetic tests to see how genes of the EPCs are changed by the patient's participation in the rehabilitation program.
NCT01609140
The purpose of this study is to evaluate the safety and cholesterol lowering effects of MPSK3169A when given as subcutaneous (SC) injections over a 24-week period to patients with a high risk of cardiovascular events and LDL-c levels well above goal.
NCT00573560
The CardioKinetix Ventricular Partitioning Device (VPD) is intended to isolate the malfunctioning portion of the left ventricle in patients with symptoms of heart failure due to ischemic heart disease. By isolating the malfunctioning portion of the left ventricle, it is hypothesized that the left ventricle will pump more effectively.
NCT02577484
This study will assess the differences between Fractional Flow Reserve (FFR) measurements made by the Navvus catheter and a commercially available pressure guidewire in up to 240 subjects where FFR is clinically indicated. All subjects will receive diagnostic treatment according to clinical indications and center standard practice.
NCT01800968
The primary objective is to test the hypothesis that, compared with placebo, therapy with Subcutaneous (SQ) GLP-1 agonist in the post-Acute Heart Failure Syndrome (AHFS) discharge period will be associated with greater clinical stability at six months as assessed by a composite clinical endpoint.
NCT01096043
Study CXL-1020-02 employs is designed to further define suitable clinical dosages for CXL-1020 which will be utilized in a later Phase IIb study. The study is conducted in 3 different stages called 'strata" and evaluates the potential utility of this drug for the treatment of patents who are hospitalized with heart failure.
NCT00000535
To test the efficacy of weight loss and sodium restriction, alone and combined, in maintaining the normotensive state following withdrawal of antihypertensive medications in an elderly cohort. Conducted in collaboration with the National Institute on Aging.
NCT01584557
The purpose of this study is to evaluate the short term efficacy and safety of tolvaptan in subjects hospitalized for worsening heart failure who have volume overload and one of the following: renal insufficiency, or hyponatremia or inadequate response to diuretic therapy. The primary variable for assessing efficacy will be self-assessed 7-point dyspnea score at 8 and 16 hours.
NCT00770146
The purpose of this study is to evaluate the safety and efficacy of dosing with mipomersen for 26 weeks in patients with high cholesterol who are on a maximally tolerated dose of statin and who have a diagnosis that puts them at least at high risk of coronary heart disease (CHD).
NCT01644331
The primary objective of this study is to compare the effects of oral Tolvaptan vs. placebo as an adjunct to fixed dose IV furosemide on dyspnea relief in patients with acute decompensated heart failure The primary hypothesis is that the addition of oral Tolvaptan to fixed dose furosemide will be more effective at relieving dyspnea than fixed dose furosemide alone
