Filter by:A single-centre double-blind placebo-controlled crossover randomised controlled trial to determine the physiological basis of glucagon-like peptide-1 receptor activation on exercise haemodynamics, as manifest through specific electrophysiological parameters measured by serial exercise stress testing, in those patients with reversible myocardial ischaemia and obstructive coronary artery disease confirmed by a baseline exercise test and coronary angiography respectively.
Coronary heart disease (CHD) pose a serious health threat to population. PCI using drug eluting stents (DES), as a well-proved and booming measure in CHD management, is invasive and of high cost, however the knowledge about the real-life DES use and the efficacy and safety in China is limited. By consecutively recruiting first-ever PCI patients in 30 geographically representative highest-rank hospitals, this study will examine the prognosis in groups with different brands of DES, and various real-life factors, that may affect patients recovery after the procedure. Evidence for clinical practice and health resource allocation will be established based on the findings, to improve patients outcomes in future finally.
RIvaroxaban for Valvular heart diseasE and atRial fibrillation trial (RIVER trial).
Cardiovascular disease (CVD) is the leading cause of death in the U.S. Efforts to improve CVD risk factors often fall short in complex patients with multiple co-morbid conditions, a growing, expensive, and high-risk segment of the U.S. population. The investigators are testing a multi-component behavioral intervention designed to help complex patients with CVD and other concurrent chronic conditions to become more effective agents of their own care.
Patients admitted as an unscheduled hospital admission with either a acute heart failure syndrome (ACF) or acute coronary syndrome (ACS) will be eligible if their 6-12 month mortality risk is estimated to be 20% or greater at the time of discharge. Mortality risk is estimated using GRACE (for ACS) or EFFECT (for AHF) scores. Patients are randomly allocated to receive a holistic care intervention based around the creation of a detailed Future (anticipatory) Care Plan which is agreed with the patient and their family and which is shared with the Family Doctor and Emergency Services including ambulance teams. Primary endpoint is quality of life assessed by questionnaire.
The HIV/HEART study (HIVH) is an ongoing, prospective, multicentre trial that was conducted to assess the incidence, the prevalence and the clinical course of cardiovascular diseases (CVD) in HIV-infected patients. The study population includes outpatients from specialized HIV-care units of the German Ruhr region, who were at least 18 years of age, were known to have a HIV-infection and exhibited a stable disease status within 4 weeks before inclusion into the trial. From March 2004 (Pilot phase) to May 2014 (7,5 year Follow-up) 1481 HIV+ patients were recruited in a consecutive manner. The standardised examinations included a targeted assessment of medical history and physical examination. Blood was drawn for comprehensive laboratory tests including HIV specific parameters (CD4 cell count, HIV-1 RNA levels) and cardiovascular items (lipid concentrations, BNP values and renal parameters). Furthermore, non-invasive tests were performed during the initial visit, including additional heart rate and blood pressure measurements, electrocardiogram (ECGs) and transthoracic echocardiography (TTE). Examinations were completed in accordance with previously defined standard operating procedures. CVD were defined as coronary, cerebrovascular, peripheral arterial disease, heart failure or cardiac vitium.
Background: Patients undergoing coronary artery bypass graft surgery often experience a range of problems and symptoms related to the procedure and the underlying heart disease.These problems include anxiety and depressive symptoms, immobility issues, complications such as wound seeping, neck and shoulder pains, interrupted and insufficient sleep. No studies have tested a combined intervention on phase 1 rehabilitation in coronary artery bypass graft surgery patients. However, randomised trials with either a physical or a mental part have been conducted with positive result, but evidence is lacking for a combined intervention. Before a large randomised trial was set up a pilot trial was conducted to evaluate the feasibility of patient recruitment and intervention: to test the safety and tolerability of the intervention by patients and to provide outcome data for sample size calculations. The SheppHeartCABG pilot showed trial feasibility, safety and sufficient inclusion rate and high compliance with most elements. Outcome data from the pilot trial has been used to sample size and power calculation in this randomised clinical trial. Objective: The objective of this trial is to investigate the benefits and harms of a phase 1 comprehensive cardiac rehabilitation programme consisting of an exercise-training and a psycho-educative component, including plus treatment as usual in patients who undergo coronary artery bypass grafting.
This is a pilot randomized controlled trial intervention to improve lifestyle behaviors (physical activity and health diet) for Filipino Americans with type 2 diabetes on metformin. If the PilAm Go4Health intervention demonstrates potential efficacy, it may identify effective intervention strategies to significantly reduce risks for heart disease risks (i.e., metabolic syndrome) in Filipino Americans.
The purpose of this study is to evaluate the ability of vascular occlusion test (VOT) during cardiac surgery to predict postoperative outcomes in pediatric patients.
Introduction: The Fontan operation is the surgical treatment in most patients with either anatomic or functional single ventricles. In this operation, the subpulmonary ventricle is bypassed, connecting the systemic veins directly to the pulmonary arteries. The lack of a subpulmonary ventricle is associated with a nonpulsatile pulmonary flow and triggers a sequence of adaptive mechanisms along the life of these patients. The most frequent consequence of these adaptative mechanisms is the reduction in functional capacity, objectively measured by the decrease in peak oxygen consumption (VO2). So, cardiovascular and pulmonary functioning and skeletal muscle alterations can explain exercise intolerance in these patients. Objectives: 1. To compare the cardiovascular, pulmonary, and musculoskeletal system variables in clinically stable Fontan patients with Healthy subjects; 2. To correlate the variables of the cardiovascular, pulmonary, and skeletal muscle with the functional capacity in Fontan patients; 3. To identify predictors of low functional capacity in this population; 4. To evaluate four-month aerobic exercise and inspiratory muscle training on functional capacity, pulmonary function, and autonomic control in patients after Fontan operation and compare to the group with no exercise training. Methods: All subjects were submitted to cardiovascular, pulmonary, and skeletal muscle evaluation at baseline to perform a cross-sectional study comparing Fontan Patients (FP) with Healthy Controls (HC). In addition, the FP accepted to participate in the longitudinal clinical trial to evaluate exercise programs were randomized into three groups: Aerobic Exercise Training (AET), Inspiratory Muscle Training (IMT), and Non-exercise Training Group (NET, a control group). All patient groups (AET, IMT, NET) were reassessed after four months of training or under usual care. Expected Outcomes: This study expects to demonstrate that impaired pulmonary function, altered neurovascular control, and reduced skeletal muscle could be an additional potential mechanism for reducing functional capacity in clinically stable Fontan patients. And this impairment could be diminished by exercise training, enhancing physical capacity, and exercise tolerance.
