The Impact of Caffeine on Brachial Endothelial Function in Healthy Subjects and in Patients With...
Coronary DiseasePrior work (Chris, M. et al, Clinical Science 2005; 109, 55-60) has demonstrated that drinking a cup of coffee (80-100 mg of caffeine) an hour before endothelium-dependent FMD (flow-mediated dilatation) of the brachial artery, effects endothelial function in healthy adults subjects. This effect might be attributed to caffeine, given that decaffeinated coffee (<2 mg of caffeine) was not associated with any change in endothelial performance. In the current study we intend to further examine the impact of caffeine on brachial endothelial function among healthy subjects & in patients with proven ischemic heart disease.
H2 Haplotype and CYP3As Polymorphisms and the Antiplatelet Response to Clopidogrel
Coronary Artery DiseaseElective Percutaneous Coronary InterventionThe purpose of this study was to assess whether interpatient variability in the platelet response to clopidogrel is partly due to polymorphisms of the hepatic cytochrome P450 (CYP450)3A and of the clopidogrel-P2Y12 receptor genes.
LV Thrombus Pilot Study for Comparing Enoxaparin Vs. Warfarin
Coronary Artery DiseaseAcute Myocardial InfarctionTo prospectively evaluate the utility of enoxaparin vs. oral warfarin in reduction of echocardiographic indices of LV mural thrombus. The primary outcome is the presence of LV mural thrombus at 3.5 months. The secondary outcome is cost analysis comparing the two arms.
Heart and Estrogen-Progestin Replacement Study (HERS)
Coronary Heart DiseaseThe purpose of the study is to determine whether hormone replacement therapy in post menopausal women with coronary artery disease prevents future heart attacks or death from coronary heart disease.
Study Tests Whether a Standardized LVR Performed With the Blue Egg Device Improves Cardiopulmonary...
Congestive Heart FailureIschemic Cardiomyopathy2 moreThe purpose of the present prospective, randomized study is to investigate the clinical effectiveness of standardized left ventricular reconstruction surgery (LVR). In order to standardize the procedure, the operation will be performed with the Blue Egg, manufactured by BioVentrix, a subsidiary of CHF Technologies, Inc.
Effect of an Educational Intervention on Cardiac Patients' Participation Rate in Cardiac Rehabilitation...
Coronary Artery DiseaseThe main aim of the study is to determine the effectiveness of an educational intervention designed to increase attendance of coronary artery bypass grafting (CABG) patients at Cardiac Rehabilitation Programs (CRPs) on actual CRP participation rate and; examine patient-related factors (demographic, health, psychosocial, awareness) influencing patients' attendance at CRPs. We hypothesized that the proportion of CABG patients participating in CRPs will increase significantly to 20-30% following the educational intervention employed.
Study of ONO-1101 in Patients Scheduled for Coronary Angiography
Coronary Artery DiseaseThe purpose of this study is to evaluate the efficacy and safety of ONO-1101 in patients scheduled for coronary angiography, in a double-blind, randomized, placebo-controlled, parallel group, multi-center study.
Vitamins in Nitrous Oxide Study
Major SurgeryCoronary Artery DiseaseIn this study, we want to find out if laughing gas (nitrous oxide) leads to a higher rate of cardiac complications after surgery in patients with a specific genetic profile (mutations in the MTHFR gene) and if this risk can be prevented by giving patients vitamin B12 and folate during surgery.
sPLA2 Inhibition to Decrease Enzyme Release After PCI Trial
Coronary Artery DiseaseAs evidence accumulates that atherogenesis or Coronary Artery Disease (CAD) may not be simply a disorder of lipid metabolism, but an inflammatory disease, the focus of treatment has shifted. A-002 or Varespladib is an anti-inflammatory drug for treatment of chronic and acute diseases. It acts by inhibiting secretory phospholipase A2 (sPLA2 ) - one of a family of enzymes leading to inflammation - which may be important in: 1) the development of atherosclerosis and 2) the increase in occurence of cardiovascular events after angioplasty. Previous studies have demonstrated that sPLA2: 1) facilitates the pro-atherogenic effects of low-density (LDL or bad cholesterol) and 2) increased levels post-angioplasty correlate with an increased risk of events at followup contact. Therefore this study proposes to investigate the ability of A-002 to prevent or reduce myocardial damage after angioplasty by inhibiting the cascade of inflammatory mediators. Substudy - Subjects who agree will also have a vascular ultrasound 24h post-PCI to assess endothelial function.
Dose Finding Study of PB127 Ultrasound Contrast Agent in Healthy Volunteers and Patients With Coronary...
HealthyCoronary Artery DiseaseThe purpose of this study is to determine the dose of PB127 for detection and/or exclusion of coronary artery disease when used with cardiac ultrasound. This study also evaluates the safety of PB127.
