Filter by:This study will assess the safety of telcagepant in coronary artery disease (CAD) participants with stable angina during exercise treadmill testing and evaluate whether calcitonin gene-related peptide (CGRP) receptor antagonism by telcagepant reduces exercise tolerance in these participants. Primary hypothesis is that telcagepant does not significantly decrease exercise duration compared to placebo, as measured by a treadmill exercise test; that is, the true treatment difference in exercise duration (MK-0974 - Placebo) >= -60 seconds.
The purpose of this study is to evaluate the additional effect of probucol or concomitant administration of cilostazol and probucol on mean carotid artery intima-media thickness (mean IMT) at year 1, 2, and 3.
Background: - Currently, heart catheterization procedures are guided by X-rays. Researchers are developing new techniques to perform heart catheterization without the use of X-rays by investigating possible uses of magnetic resonance imaging (MRI) scans. To study these uses, researchers are interested in performing a part of the standard X-ray catheterization procedure using MRI on individuals who are scheduled to have heart catheterization. Objectives: - To examine the safety and feasibility of right-heart catheterization using MRI-guided catheters. Eligibility: - Individuals at least 21 years of age who are undergoing a medically necessary heart catheterization procedure. Design: - The research MRI procedure will be performed either before or after standard X-ray guided heart catheterization. - Participants will be transferred from an X-ray table onto an MRI table and advanced into the scanner. Under MRI guidance, a MRI-compatible catheter will be used to measure blood pressure and blood oxygen levels in the heart, and MRI scanning will be performed for approximately 30 minutes.
Identification of the pathophysiology associated with Eisenmenger's syndrome has led to the evaluation of targeted therapies. Iloprost, a prostacyclin analogue, is one such targeted therapy used in patients with Eisenmenger's syndrome. The purpose of our study is to assess the effects of inhaled iloprost on patients with Eisenmenger's syndrome.
Children with Cancer or congenital heart disease (CHD) experience complex, physical, psychosocial and behavioural symptoms and problems due to the illness, treatment, and medical procedures. To help children cope with their problems and prevent psychological distress, the investigators developed SiSom, a support system to help children with cancer or CHD report their symptoms and problems in an age-adjusted manner on a touch-pad, portable computer. This quasi-experimental study with 202 children age 7-12 with CHD or cancer will test the following hypotheses: When children use SiSom to report their symptoms and problems, and this information is provided to their clinicians in their outpatient consultations: - Children and parents will experience less anxiety. - Children and parents will be more satisfied with the outpatient visit. - There will be greater congruence between children's reported symptoms and problems and those addressed by their clinicians as evidenced in documented patient care. To better understand the mechanisms by which these effects may occur, the investigators will also explore: - Differences between control and experimental groups in patient-provider communication in terms of instrumental and affective behaviour, participation, initiative and person addressed; - The relationships among outcomes of patient-provider communication, congruence between patients' reported symptoms and those addressed by their clinicians and children's and parents' anxiety and satisfaction; and how these relationships differ between treatment and control conditions. Finally, the investigators will investigate time requirements, ease of use and usefulness of SiSom by children and clinicians. For analyses the investigators will use inferential statistics and qualitative analyses of the video-taped consultation sessions. This study will contribute to improving patient-centred care for a particularly vulnerable population, and to a better understanding of the triadic communication and interactions among child-parent and clinician.
The objective of this study is to evaluate the safety and effectiveness of the clinical and technical performance of the CorPath® 200 System in the delivery and manipulation of coronary guidewires and stent/balloon systems for use in percutaneous coronary interventions (PCI).
It gave a clinical trial which will be included in the 60 infants, aged up to 24 months, diagnosed with congenital's population will be divided by simple randomization into three groups: 20 infants in the intervention group, 20 infants in the control group, not receive the RTA technique and another 20 infants in a placebo group, we just get the support manual therapist for 5 minutes. Initially the data will be collected cardio heart rate, respiratory rate and oxygen saturation. Then the researcher will apply three specific rating scales, based on clinical presentation and behavior of infants. Hypothesis: The RTA improves cardiorespiratory parameters and reduces signs of discomfort and pain of infants with congenital heart acyanogenic.
This study will determine whether the psychological and physical benefits of expressive writing extend to obese in-patients with Ischemic Heart Disease (IHD)referred to cardiac rehabilitation
In this study, 80 coronary artery disease patients with successful coronary revascularisation (by CABG or PCI) will be included. Patients are excluded in case of: congestive heart failure, ICD or pacemaker, any disability limiting exercise participation. These patients are attending phase 2-3 cardiac rehabilitation, and have completed 6 weeks of rehabilitation. Next, subjects are randomly assigned to a control group or an intervention group. Outcome parameters: physical activity, exercise capacity, blood glucose, insulin level and lipid profile, body weight and waist circumference, cardiovascular morbidity and mortality. Hypothesis: telemonitoring of physical activity will increase physical activity, and improve cardiovascular disease risk factors, in CAD patients attending phase 2-3 cardiac rehabilitation.
To investigate whether the use of Corus CAD (Age/Sex/Gene Expression score - ASGES) blood assay changes the diagnostic testing pattern in patients referred to a cardiologist for the evaluation of chest pain or anginal equivalent symptoms.
