Filter by:The purpose of this Clinical Evaluation is the continued assessment of the XIENCE Everolimus Eluting Coronary Stent System (XIENCE V® and XIENCE PRIME⢠EECSS) with the primary focus on clinical outcomes in the treatment of female patients with de novo coronary artery lesions, and the characterization of the female population undergoing stent implantation with a XIENCE stent.
Many stress tests being done today have two parts, the stress test and the pictures of your heart. The investigators are comparing a newer technique to obtain the pictures (PET imaging) to the standard method (SPECT imaging). However, it is not known if the new test is better than the old test. It is important to have a standard to compare these tests to, and that is why people who will be getting a cardiac catheterization are being asked to participate. The information about your arteries from the cardiac catheterization will be used to judge which stress test is better. The investigators hypothesize that the newer method (PET imaging) will be more accurate than the old method (SPECT) in detecting heart disease.
The purpose of this study is to investigate the prevalence of cardiac disease/coronary artery disease and diagnostic yield of different non-invasive methods in patients with type 2 diabetes 40-75 years of age at examination. Exercise tests, Doppler echocardiographic examination with Tissue Velocity Imaging, stress Echocardiography, transthoracic Doppler of coronary arteries with coronary flow reserve, and cardiac MRI with late enhancement at rest, and perfusion after vasodilatation stress will be used in the study. A subpopulation will in addition measure forearm vasodilation(FMD) and CFR before and after 4 months of exercise training.
Heart attacks and strokes caused by the unstable atherosclerotic plaques remain the leading cause of death in the United States. Unstable plaques often have more fat than stable plaques. This study will investigate if a treatment with LDL-lowering plus HDL-raising compared with LDL-lowering alone would more effectively reduce the plaque fat content assessed by magnetic resonance imaging (MRI), therefore, further reducing heart attacks and strokes.
This is a prospective, randomized, active-controlled, open label, parallel two-arm, multi-center, post-approval study descriptively comparing the XIENCE V EECSS to the CYPHER SELECT PLUS Sirolimus-Eluting Coronary Stent System (SECSS) ("CYPHER SELECT PLUS") during commercial use in China.
MTWA-CAD is a feasibility study designed to evaluate Microvolt T-Wave Alternans (MTWA) testing for the purpose of detecting active ischemia in patients with known or suspected coronary artery disease (CAD). MTWA is a subtle, alternating pattern in the T wave portion of the surface electrocardiogram (ECG) that is associated with increased risk of ventricular tachyarrhythmias and sudden cardiac arrest (SCA).
The aim of the study is to compare three different regimens for volume replacement during cardiac surgery, e.g. Albumin 5%, Hydroxyethylstarch 130/0.4 (HES) and Ringer-Lactate (RL). Main Outcome parameters: chest tube drainage and coagulation parameters. The investigators hypothesis is that HES is as safe as Albumin, however less expensive. Whether RL is an even less expensive and as safe alternative has to be shown.
To assess the safety and feasibility of the use of the Tryton bifurcation coronary stent system for the treatment of single de novo bifurcation lesions in native coronary arteries.
The primary aim of the study is to assess and follow-up subjects that received AdGVVEGF121cDNA in IRB protocol #0794-894 entitled "Phase I Study of Direct Administration of a Replication Deficient Adenovirus Vector (AdGVVEGF121.10) Containing the VEGF121 cDNA to the Ischemic Myocardium of Individuals with Diffuse Coronary Artery Disease" and IRB protocol #0297-693 entitled "Phase I Study of Direct Administration of a Replication Deficient Adenovirus Vector (AdGVVEGF121.10) Containing the VEGF121 cDNA to the Ischemic Myocardium of Individuals with Diffuse Coronary Artery Disease Via Minimally Invasive Surgery".
The purpose of this Clinical Evaluation is a continuation in the assessment of the performance of the XIENCE V® Everolimus Eluting Coronary Stent System (XIENCE V® EECSS) in the treatment of patients with de novo coronary artery lesions in patients (Diabetic sub-study).
