Filter by:The main aim of this trial is to assess the long-term prognostic value of different types of Factor XIIa in an unselected, single center series of 871 chest pain patients admitted to the emergency unit, employing blood samples collected at admission. The second purpose of this study is to assess the incremental prognostic value of B-type natriuretic peptide (BNP) and high-sensitive C-reactive protein (hsCRP). A third purpose of this study is to evaluate the prognostic impact of the Omega-3 Index which is a measure of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) relative to other fatty acids in the erythrocyte membrane.
This is a multi-center and multi-national,randomized, double blind, placebo-controlled, 28-day treatment study with BAY 68-4986 taken orally or a matching placebo.
The PREDICT study is to develop and validate a diagnostic blood ASGES (age, sex, gene expression score) or Corus CAD for atherosclerotic coronary artery disease (CAD). The Corus CAD (Age/Sex/Gene Expression score - ASGES) will use quantitative real-time PCR (RT-PCR) to quantify the expression of multiple genes from circulating peripheral blood cells to assess the presence of clinically significant CAD in a patient.
The current outpatient evaluation for angina in low and intermediate risk patients typically starts with a functional assessment for coronary ischemia. Exercise treadmill testing is often selected as the initial diagnostic modality for coronary artery function. However, exercise treadmill testing is limited by its moderate sensitivity and specificity, often resulting in further cardiac resource utilization for patient risk stratification and reassurance. With the advent of coronary multislice computed tomography (MSCT) angiography, coronary artery anatomy can now be evaluated noninvasively. Despite its impressive performance characteristics, the role of coronary MSCT angiography in the outpatient evaluation of angina remains undefined. CT-EXTRA compares the impact on patient safety and downstream resource utilization of a novel initial diagnostic strategy employing the addition of coronary MSCT angiography to exercise treadmill testing with a standard diagnostic strategy of exercise treadmill testing for the ambulatory evaluation of low-intermediate risk patients with possible angina. The study is a single center, prospective, non-blinded, randomized clinical trial. Men and women, age 18-70, with a low to intermediate pretest probability of coronary artery disease who are referred for an exercise treadmill test for angina are eligible. Subjects are randomized either to an initial diagnostic strategy of exercise treadmill testing or exercise treadmill testing with coronary MSCT angiography. Subsequent diagnostic testing and treatment are the discretion of the referring physician. Subjects will be clinically followed for 24 months. The clinical impact on patient safety and downstream clinical resource utilization of this novel diagnostic strategy in which both coronary artery anatomy and function are initially evaluated will be determined. The primary outcome is a composite endpoint consisting of freedom from adverse cardiac events, further cardiac diagnostic testing, and future cardiac clinical encounters. Secondary outcomes include the impact on the indiscriminate use of coronary angiography, subject anxiety, depression, motivation for healthy behavioral change, and satisfaction with diagnostic evaluation and use of antiplatelet and antilipid therapy. Lastly, the cost effectiveness of the routine addition of coronary MSCT angiography in the outpatient evaluation of possible angina will be determined.
The purpose of the study is to determine for how long sildenafil potentiates the blood pressure reduction that occurs with glyceryl trinitrate in men with angina.
Cell transplantation for treatment of heart failure is a novel field of translational research that offers the perspective of developing curative approaches by regenerating or "rejuvenating" lost and/or diseased myocardium and inducing growth of new blood vessels. Based on the safety and preliminary efficacy testing in previous trials, a stringent efficacy testing will be performed in this study. Sixty patients who had myocardial infarction in the past and now need bypass surgery for ongoing coronary artery disease will undergo either bypass surgery and placebo treatment or bypass surgery and injection of CD133 bone marrow cells directly in the heart muscle. The study will be fully blinded, i.e. neither the patient nor the surgeon knows what substance is injected (placebo or cell product). Patients will be followed for 6 months and various heart function measurements will be performed.
The purpose of this study is to determine whether a one-time intracoronary infusion of Ad5FGF-4 is effective in reducing the time to onset myocardial ischemia as measured by exercise treadmill testing and improving myocardial blood flow as measured by SPECT imaging. Exercise capacity, angina functional class, patient symptoms and quality of life will also be evaluated to characterize the efficacy of Ad5FGF-4. Short-term and long-term safety of Ad5FGF-4 will also be evaluated.
The purpose of this study is to determine if long-term vasodilatory treatment is more effective than the standard treatment in hypertensive patients with microvascular angina pectoris
Evaluation of an intracoronary injection of ex-vivo generated autologous Angiogenic Cells Precursors (ACPs) to treat patients suffering from severe angina not responsive to maximal drug treatment or not willing or without option of undergoing percutaneous coronary intervention (PCI) or coronary artery bypass graft surgery (CABG). The use of ACPs aims to promote the formation of new vascularization and thus viable myocardial tissue.
The purpose of this study is to determine whether cardiac rehabilitation is a successful treatment for refractory angina, in relation to improvements in cardiovascular risk factors, physical ability, symptomology, quality of life and psychological morbidity.
