NCT00687856
Heart failure is a progressive disorder in which the weakened heart is not able to efficiently pump blood throughout the body. When the body's cells do not receive enough blood, this can result in fatigue, shortness of breath, and difficulty carrying out daily activities. The left ventricular assist device (LVAD) is a device that is used to provide mechanical circulatory support to patients with end-stage heart failure who are awaiting heart transplants. Although LVAD support helps maintain the pumping ability of the heart and dramatically improves heart failure symptoms, the quality of life with LVAD support is far from ideal. It has been shown that LVAD support in selected patients may restore the failing heart enough to eliminate the need for heart transplant, but more information is needed to assess heart recovery and to guide weaning of LVAD support. Using data collected from patients who have undergone LVAD implantation, this study will attempt to better assess heart recovery and to generate criteria for identifying patients eligible for the removal of LVAD support.
NCT00938340
The purpose of this study is to evaluate the acute, postprandial effects and mechanism of action of various walnut components (separated nut skins, de-fatted nut meat, nut oil) versus whole walnuts on oxidative stress, inflammation and measures of platelet and endothelial function in healthy adults with moderately elevated cholesterol levels.
NCT00937963
Diacylglycerol (DAG) is a molecule that consists of two fatty acid chains bound by ester links to a glycerol molecule, in the form of 1,2 and 1,3 structural isomers. Approximately 10% of the edible oils on today's market are comprised from DAG. DAG oil has a similar taste, appearance, and fatty acid composition as conventional triacylglycerol oil (TAG; consists of 3 fatty acids chains bound to a glycerol molecule), yet recent studies suggest that due to its different chemical structure, DAG oil may induce cardiovascular (CV) benefits. Specifically, human studies in the United States (US) and Japan have shown that long-term consumption of a diet containing DAG oil enhances loss of body weight and body fat compared with TAG oil of similar fatty acid composition. In postprandial studies, serum triglycerides (TG) and remnant like particle cholesterol concentrations, have shown to be lower following ingestion of DAG-enriched oil compared to conventional dietary oil (e.g., soybean, corn), or TAG oil. Therefore, DAG oil appears to be effective for preventing postprandial hyperlipidemia, which is a risk factor for arteriosclerosis. The hypothesis that the investigators propose in this pilot study is that intake of DAG oil, compared to TAG oil will result in a lower LDL-C, and lower LDL-C/HDL-C ratio, as well as a reduction in TG levels. Given the significance of such findings, if confirmed, the investigators will evaluate other important clinical biomarkers for chronic disease (CV Disease, type 2 diabetes, metabolic syndrome), such as insulin sensitivity and inflammation \[as determined by C-reactive protein (CRP), interleukin (IL)-1, IL-6 \& tumor necrosis factor-alpha (TNF-α)\], which also may be beneficially affected by consumption of the palm DAG oil. During the pilot study, the investigators will reserve serum/plasma samples so that these additional assays may be run upon approval of the modification.
NCT00937638
The proposed research will provide important information about the role of 2 intervention diets that provide different amounts of lean beef and meet current nutrient recommendations for the treatment of Metabolic Syndrome (MetSyn), a chronic disease that is still increasing in prevalence at alarming rates. The experimental and diet designs will enable us to evaluate lifestyle interventions for MetSyn for persons who maintain weight, lose weight and maintain their weight loss, as is currently recommended in clinical practice. Importantly, the investigators will compare a diet high in lean beef (5 oz/day) which is compositionally similar (i.e., energy and nutrients) to the modified-DASH diet, a low beef diet which has become the Gold Standard for the management of cardiovascular disease (CVD) risk factors, including MetSyn. In addition, the investigators also will evaluate a moderate-high protein diet (BOLD+) that is higher in total protein (from mixed sources including lean beef, 7oz/day) than the BOLD diet, on CVD risk factors in persons with MetSyn. A follow-up study was conducted to assess dietary compliance in a sub-sample of the population at 12-months; participants were not informed of this end-point and additional consent was obtained. Hypotheses: 1. Healthful isocaloric diets that include lean beef as the primary source of protein (BOLD diet) with average (18%; BOLD) or moderate-high (28%; BOLD+) total protein intake will show similar or greater reductions in CVD risk, respectively when compared to a modified-DASH diet. 2. A healthful weight-loss diet, including lean beef as the primary source of protein in a high-moderate protein diet (BOLD+ diet), plus regular exercise (BOLD+ + ex) will reduce body weight equal to that of a BOLD + ex and DASH + ex intervention, but may improve CV risk factors (such as BP and TG), and therefore reduce the prevalence of MetSyn more than a BOLD + ex and DASH + ex intervention. 3. The BOLD diet will be more effective than the modified-DASH diet, and the BOLD+ diet more effective than the BOLD diet in maintaining the CVD benefits attained during phases 1 and 2. Dietary adherence will be better on the BOLD and BOLD + diets compared with the modified DASH diet.
NCT03476187
Subjects meeting the inclusion/exclusion criteria will wear the µCor for at least 90 days. During the study, clinic follow up will occur every 30 days. For all subjects, each scheduled clinic visit will include assessment of cardiac symptoms and any relevant clinically actionable events. The subject will be given a daily diary to track symptoms, unplanned hospital visits, medication changes, and all other heart failure related clinical events. Weekly phone calls to the subject will be given throughout the duration of the study to remind the patient to use the subject diary and to collect and record heart failure related clinical events. Subjects will be contacted six months and one year from initial enrollment to assess the vital status of the subject, any heart failure related clinical events since the end of µCor wear, and any health care utilization since the end of µCor wear.

New therapy tested in heart failure with preserved ejection fraction (HFpEF) patients with approved indications for pacing to determine if elevated pacing therapy is tolerated and whether there is a signal for efficacy.
NCT05202509
This study will be a placebo-controlled, double-blind, randomized, phase 3 study in participants with Atherosclerotic Cardiovascular Disease (ASCVD) who are not adequately controlled despite maximally tolerated lipid-lowering therapy.
NCT00826280
Observe whether the administration of caffeine prior to regadenoson will affect the interpretation of test results in subjects with coronary artery disease (CAD) undergoing SPECT MPI
NCT02787785
The MADIT S-ICD trial was designed to evaluate if subjects with a prior myocardial infarction, diabetes mellitus and a relatively preserved ejection fraction of 36-50% will have a survival benefit from receiving a subcutaneous implantable cardioverter defibrillator (S-ICD) when compared to those receiving conventional medical therapy. The trial enrollment was stopped in 2018 due to lower than expected enrollment, all subjects enrolled at that time were followed for approximately 5 years.
