The primary objective is to evaluate the effect of 12 weeks of subcutaneous evolocumab every 2 weeks or every 4 weeks, compared with placebo, on percent change from baseline in low-density lipoprotein cholesterol (LDL-C) when used in addition to statin therapy in Japanese adults with hypercholesterolemia and high cardiovascular risk.
NCT02632487
This study will evaluate the feasibility and efficacy of combining a traditional, structured exercise intervention with an innovative intervention designed to decrease sedentary behavior and increase non-exercise physical activity (NEPA).
NCT01971944
Purpose: To compare the hemodynamic effects of dobutamine and milrinone in hospitalized patients who are receiving Beta Blocker Participants: Patients who are admitted to the General Cardiology and Heart Failure Services at the University of North Carolina Hospitals with acute decompensated heart failure, who have maintained steady state concentrations of beta blocker therapy (carvedilol or metoprolol), and who are deemed by the health care team to require pulmonary artery catheter placement and inotropic therapy with dobutamine or milrinone by continuous infusion. Patients that are not currently receiving beta blocker therapy will be enrolled for comparative purposes; however, any patient not at steady state (on or off beta blocker therapy) will not be enrolled. Procedures: After obtaining informed consent, patients will be assigned to the appropriate sub-study group based on beta blocker use (Study A: patients on stable doses of metoprolol and Study B: patients on stable doses of carvedilol). All patients should receive dobutamine followed by milrinone as outlined in the dosing algorithm (see inotrope dosing algorithm attached, as part of the usual standard of practice). Baseline pulmonary artery catheter hemodynamic parameters will be collected prior to administration of inotrope trial of dobutamine followed by milrinone. Hemodynamic parameters will be recorded per the dosing algorithm following initiation and dose titration. Dose titration will be determined by the health care team based upon patient response or lack thereof and tolerability. Changes in hemodynamic parameters in response to dobutamine or milrinone will be compared within study groups. Additionally, data will continue to be collected on patients receiving not beta blocker therapy for comparative purpose.
NCT02595814
The clinical characteristics, initial presentation, management, and outcomes of patients hospitalized with new-onset (first diagnosis) heart failure (HF) or decompensation of chronic HF are poorly understood worldwide. REPORT-HF is a global, prospective, and observational HF disease registry designed to characterize patient trajectories longitudinally during and following an index hospitalization for acute HF.
NCT03552432
the purpose of this study is to show that alirocumab with statin therapy have a s tronger stabilizing effect on vulnerable plaque in coronary artery disease than statin alone administration
NCT03054090
Most care for chronic conditions is provided by primary care clinicians. Although Virginia ranks 4th among the 50 states in average income, it ranks 27th in mortality due to heart attacks and strokes. The scope and focus of this project will materially improve the rates of screening and treatment of risk factors for heart attacks and strokes, and will give primary care clinicians the tools and training to improve the care of other chronic illnesses and the delivery of preventive services.
NCT03735186
The present study will investigate the effect of acute exercise on fasting and postprandial risk markers for coronary heart disease (CHD) in healthy male cigarette smokers and non-smokers. Participants will complete two, 2-day trials in a random crossover design separated by an interval of at least 1 week. On day 1, participants will rest (control) or complete 60 minute of treadmill exercise at 60% of maximum oxygen uptake (exercise). On day 2, participants will rest and consume two high fat meals (breakfast and lunch) over an 8-h period during which 13 venous blood samples and nine blood pressure measurements will be taken at pre-determined intervals. It is hypothesised that men who smoke cigarettes will exhibit impaired fasting and postprandial metabolic risk markers compared to non-smokers, but a single bout of exercise will be equally, if not more, efficacious for improving the CHD risk factor profile in smokers than non-smokers.
NCT00083772
Primary objective is to assess the effect of nesiritide in decreasing left ventricular (LV) filling pressure, defined as pulmonary artery capillary wedge pressure (PCWP) in a group of patients admitted with acute diastolic heart failure. Secondary objectives include: improvement in symptoms, exercise tolerance, improvement in Doppler diastolic filling parameters in patients with diastolic heart failure.
NCT03712644
The objective of the INCORPORATE trial is to evaluate whether an intentional invasive strategy with ischemia targeted, reasonably complete coronary revascularization and optimal medical therapy is superior as compared to a primary conservative approach and optimal medical therapy alone in terms of spontaneous myocardial infarct-free and overall survival in patients with severe peripheral artery disease, underwent peripheral artery revascularization due to critical limb ischemia. The INCORPORATE trial is designed to be non-blinded, open-label, prospective 1:1 randomized controlled multicentric trial.
NCT01252316
Each year in the United States, 300,000 people suffer from Cardiac Arrest (CA), and of them there is a 90% mortality rate. Out-of-Hospital arrests in particular have a 1-5% survival to hospital discharge. High quality CPR is crucial to lowering the mortality rate and increasing survival, yet only 15-30% of out-of-hospital CA victims receive bystander CPR. Studies have shown that prompt administration of CPR dramatically improves outcomes. In a recent study from Switzerland, lay bystander CPR doubled the survival rate at one month. Our study will look to train family members of at-risk cardiac patients in the skills of CPR through the American Heart Associations (AHA) CPR Anytime Friends and Family Personal Learning Program (CPR Anytime) to see if these family members are able to learn and perform quality CPR in the event that their family member should suffer a cardiac arrest. The unique feature of the CPR Anytime training is that it is a low-cost, self-learning, video-based program that can be completed in under 30 minutes, saving the time and expense of traditional CPR training courses. While initial work has proven that teaching CPR in hospital using the VSI kit is feasible, little research has been conducted to make the program sustainable.

NCT01833910
Prompt delivery of cardiopulmonary resuscitation (CPR) can double a victims chance of survival from cardiac arrest (CA), yet it is provided in less than 1/3 of witnessed events. Studies indicate that video-based education methods can effectively train bystanders in CPR. Using the education and evaluation methods of an existing in-hospital training program, the investigators will assess the CPR skills of students taught with video-only methods, with and without psychomotor skills practice, and compare them to those using a video self-instruction (VSI) kit.
NCT02767024
Single center, prospective, randomized, non-blinded research study comparing intravenous vasodilator infusion vs. inotropic infusion in patients admitted to the hospital or in the emergency room at Montefiore Medical Center presenting with the diagnosis of acute decompensated systolic heart failure with low cardiac output but no hypotensive.
NCT03659877
The primary objective of this study is to identify and evaluate the range of values provided by accelerometers during a variety of typical daily lifestyle activities for heart failure patients, and to relate these to the measured intensity of performing each activity in the heart failure population.
NCT03584321
The study will estimate the current status of participants with non-obstructive coronary artery disease confirmed via coronary angiography.
NCT02970071
The objective of this study is to use of STIC technology to assist the traditional echocardiography to diagnose the fetal congenital heart disease accurately and then to provide a basis for prenatal counseling.

The Finnish Vitamin D Trial (FIND) is a randomized, double-blind, placebo-controlled, 5-year supplementation study of the benefits and risks of vitamin D in the primary prevention of cardiovascular (CVD) and cancer among 18000 men 60 years or older and women 65 years or older. \[Edit 25.3.2015: Due to difficulties in recruitment and funding, the study size is approximately 2500 subjects, with a 550 subject subgroup with more detailed examinations\] The participants will be randomized to 3 groups with 6000 in each, with daily supplementation of either: 1) 40 µg/day (1600 IU) of vitamin D3, 2) 80 µg/day (3200 IU) of vitamin D3, or 3) placebo. \[Edit 15.3.2015: The 2500 subjects are randomized in 3 groups, approximately 830 subjects per group.\] Compliance, use of non-study drugs or supplements, diet, development of endpoints, and CVD and cancer risk factors will be assessed by questionnaires. Blood samples will be collected for assessment of effect modification by baseline 25-hydroxyvitamin D, as well as for future ancillary studies of genetic/biochemical hypotheses. Event data will be obtained by record linkage from the national computerized hospitalization registry.
NCT02759263
Executive dysfunction can profoundly impact all dimensions of a child's development. Impairments in executive function are a central component of the neurodevelopmental phenotype associated with CHD, and manifest as behavioral dysregulation and problems with attention, working memory, and organization/planning abilities. Identifying effective treatment strategies is vital for providing optimal care for these patients. The Cogmed executive function intervention, an evidence-based computerized neurocognitive program, improves outcomes in several pediatric populations. The investigators propose to conduct a pilot study to evaluate its efficacy in reducing morbidities in patients with CHD. This is a single center, single blinded 2-arm randomized controlled trial to test the immediate post-treatment and 3-month follow-up efficacy of Cogmed intervention versus standard of care in adolescents with CHD.
