NCT01872234
The purpose of this trial or study is to determine if pacemaker therapy can be a beneficial alternative to conventional medical therapy in patients with a history of moderate heart failure. The investigators are looking to enroll approximately 180 people in this trial. Patients will be randomized in two groups. One group will be implanted with a pacemaker and will continue to receive conventional medical therapy as prescribed by their doctor. The second group will continue to receive conventional medical therapy as prescribed by their doctor and will not be implanted with a pacemaker. Clinical histories, physical exams, and external device testing will be collected both at the time of enrollment in the trial and during follow-up study visits. Patients who enter the study will be seen for study visits at 1 month, 3 and 6 months.

NCT02113150
In this prospective, randomized, clinical trial, we have investigated the effects of ketamine-based and remifentanil-based anesthetic protocol on perioperative serum cystatin-c levels, and creatinine and/or cystatin-c based eGFR equations in terms of acute kidney injury in CABG surgery.This study was approved by the Ethics Committee of Hospital and all patients were informed and gave written consent. Patients scheduled for elective CABG with cardiopulmonary bypass. Patients were randomly allocated to anesthesia with remifentanil-propofol-midazolam (RPM) group or ketamine-propofol-midazolam (KPM) group. Blood samples were obtained before induction of anesthesia (baseline), at the end of the operation, and postoperative days 1, 2, and 4.
NCT01821287
The purpose of this study is to understand the causes of growth failure and to define biochemical markers of nutritional failure in patients with single ventricle Congenital Heart Disease (CHD).
NCT02109055
The major cause of mortality worldwide is due to cardiovascular diseases. A way to treat these diseases is coronary artery bypass grafting, one of the most common surgical procedures in the world. The incidence of post-operative complications contributes to functional decline of the patient, reduced quality of life and post-discharge mortality. Also, cardiac surgery leads to changes in lung capacity and respiratory muscle strength, causing a decrease in the function lung. Physical therapy proves to be an effective tool to combat changes resulting from cardiac surgery, demonstrating beneficial results in the pulmonary function, functional capacity, and peripheral and respiratory muscle strength. The Pilates method has been studied as a therapeutic way to healthy subjects and various kinds of diseases, but there are no studies in the literature evaluating the effect method in patients after coronary artery bypass surgery. The aim of this study is to investigate the effect of Pilates on functional capacity , flows and lung volumes, respiratory and peripheral muscle strength after coronary artery bypass grafting. Randomized clinical trial in which patients will be eligible after elective coronary artery bypass surgery, randomly allocated into two groups : conventional physiotherapy group (n = 15) and Pilates method associated with conventional physiotherapy group (n = 15). The outcomes will be assessed by blinded evaluator and data randomization will be performed through by electronic randomization.The interventions will take place during the length of stay in the hospital, totalizing a maximum of six days of intervention. It is expected that the application of the Pilates method exercise method associated with conventional physiotherapy in patients in postoperative coronary artery bypass grafting improves functional capacity, flows and lung volumes and respiratory and peripheral muscle strength.
NCT01798745
The purpose of this study is to assess the pharmacokinetics (ie, how the body affects the drug) and pharmacodynamics (ie, how the drug affects the body) of JNJ-54452840 in participants with heart failure and anti-beta1-adrenergic receptor autoantibodies. The safety and tolerability of JNJ-54452840 will also be assessed.
NCT00217919
The purpose of this study is to compare a health-counselor mediated telephone counseling intervention to usual care to reduce low density lipoprotein cholesterol (LDL-C) levels in patients with peripheral arterial disease (PAD).
NCT01231815
Heart transplantation is the ultimate therapeutic option in patients with end-stage heart failure. Since advances in the treatment of acute rejection has increased early transplant survival, cardiac allograft vasculopathy (CAV) is the main factor limiting long-term survival. The prevalence of angiographically proven CAV is high, documented in 40-50% of transplant recipients 5 years after transplantation. Therefore, annual coronary angiography remains widely used to monitor transplanted patients, although pathologic studies and intravascular ultrasonography have demonstrated that coronary angiography underestimates the severity of CAV. Perfusion SPECT may underestimate allograft vasculopathy in case of diffuse coronary lesions. In this setting, the assessment of coronary reserve by means of Positron Emission Tomography (PET) and perfusion cardiac magnetic resonance imaging (CMR) have not been investigated.
NCT01259297
This study was planned to provide new information regarding the role of aliskiren (with or without additional therapy with a diuretic or a Calcium channel blockers (CCB)) in elderly individuals (≥ 65 years) with systolic blood pressure (SBP) 130 to 159 mmHg, in preventing major cardiovascular (CV) events and on global measures of physical, executive and cognitive function.
NCT00349895
This is a multi-center, prospective, non-randomized study. Approximately 90 patients from up to 16 centers will be entered in the study. Patients will be followed clinically for up to 5 years post-procedure. All patients will have a repeat angiography at 6 months follow-up. The primary objective of this study is to evaluate the safety and effectiveness of the Genous Bio-engineered R stentTM in conjunction with optimal statin therapy (80mg of atorvastatin), in the treatment of elective patients with up to two de novo native coronary artery lesions. The Genous stent received CE mark for the intended indication in August 2005
NCT02105870
Microvascular dysfunction is a key determinant of pathogenesis and outcome in patients suffering an acute myocardial infarction. The investigators hypothesise that treatment with intracoronary abciximab, a potent anti platelet agent, at the time of coronary stent insertion, will improve microvascular function.
NCT01960218

NCT00000554
To evaluate innovative diagnostic methods that will improve the diagnostic reliability of cardiovascular testing in evaluation of ischemic heart disease in women. Innovative approaches proposed include physiologic or functional measurements such as impaired metabolism, perfusion, or endothelial function as well as assessment of epicardial coronary arteries by angiography. Other objectives include developing safe, accurate, and cost effective diagnostic approaches for evaluating women with suspected ischemic heart disease, and determining the frequency of myocardial ischemia in the absence of significant epicardial coronary stenosis, as well as the frequency of non-ischemic or non-cardiac chest pain. A key aspect of the WISE study is to determine whether evidence of myocardial ischemia occurs in the absence of obstructive coronary disease.
