Active clinical trials for "Myocardial Ischemia"

The purpose of this 4 group (2x2) pilot randomized controlled trial is to test the feasibility and logistics of incorporating genetic risk information (9p21)into standard Coronary Heart Disease (CHD) risk counseling or health coaching intervention (or both) in primary care at 2 Duke Clinics.

Background: - Magnetic resonance imaging (MRI) is type of imaging study that uses magnetic fields and radio waves to take pictures of the body. To help the images show up more clearly, a contrast agent is injected into a vein. Researchers are interested in finding contrast agents that can help show problems with the blood vessels around the heart. They want to test an agent called Gadofosveset Trisodium to see how it works in MRI scans. Objectives: - To test the effectiveness of Gadofosveset Trisodium as a contrast agent in heart MRI scans. Eligibility: - Healthy volunteers between 18 and 45 years of age. Design: Participants will be screened with a physical exam and medical history. They will provide blood samples before the scanning sessions. Participants will have an MRI scan after the screening visit. They will have a dose of the contrast scan before the study. Participants will return for one additional MRI scan within 1 to 2 months of each scan. Different doses of the contrast agent will be used for each scan. An additional blood sample will be collected within 1 week of the second MRI scan.

The present study aims is to investigate: whether patients suffering from acute resp. chronic ischemic heart disease show higher levels for cadmium (Cd), lead (Pb) and mercury (Hg) than local and international reference levels suggest; the correlation between severity of coronary artery disease and angiogenic and angiostatic factors (endostatin-ES, angiostatin-AS, VEGF-vascular endothelial growth factor, osteopontin-OPN) The patient population consists of about 270 female and male patients suffering either acute or chronic ischemic heart disease (AIHD:ICD-10 I21; CIHD: ICD-10 I25). whether patients suffering CAD and valve calcification (mitral annulus, aortic valve) show higher levels of endostatin, angiostatin, osteopontin and VEGF compared to patients with CAD but without valve (annulus) calcification The measurement of cadmium (urine), lead, mercury, zinc, endostatin, angiostatin, VEGF (serum) and osteopontin (plasma) in patients with angiographically verified coronary artery disease are in the fore. Furthermore, basic laboratory diagnostics as well as data from coronary angiography and echocardiography will be collected. Additionally, the investigators will inquire heavy metal exposition during life by an interview. Recruitment will be done during the in-patient stay at the General Hospital of Vienna, Medical University of Vienna.

The purpose of this study is to evaluate effectiveness and safety of Orsiro™ Drug Eluting Stent in Routine Clinical Practice

"The impact on fluid loading after cardiac surgery by use of two different priming solution" Fluid overloading with oedema formation is a regular finding following on-pump cardiac surgery and may contribute to postoperative organ dysfunction. Myocardial oedema has been reported to impair both systolic and diastolic function. An association between intraoperative fluid loading and postoperative adverse outcome has been demonstrated in cardiac patients. The investigators have experience with the use of both colloides and combination fluids (hypertonic saline/colloides) in several experimental studies (pigs). In one animal study the investigators used colloides as an additive to the CPB-prime. The investigators observed reduced fluid leakage and less total tissue water in several organs. The planned study includes patients scheduled for coronary artery bypass, and who have no co-morbidity. The patients will be randomized to receive either Tetraspan® (HES) or acetated Ringer's solution in the CPB-prime. Accurate accounts of fluid additions, blood loss and diuresis will be kept. Determination of cardiac output (C.O.), intrathoracic blood volume (ITBV), extravascular lung water (EVLW) and global end diastolic volume (GEDV) will be monitored by use of the transpulmonary thermodilution technique PiCCO®plus system.

The purpose of this study is to evaluate the efficacy of nicorandil in the achievement of maximal coronary hyperemia compared with adenosine.

The objective of this study is to evaluate effectiveness and safety of XIENCE PRIME stent in the "real world" daily practice as compared with other drug eluting stents (DESs)

The objectives of the PMS are to observe the frequency, type, and degree of device deficiency to assure the safety of the new medical device (XIENCE PRIME) as well as to collect information on evaluation of the efficacy and safety for reevaluation.

This registry is a clinical post-market evaluation of the Orsiro LESS in subjects requiring coronary revascularization with Drug Eluting Stents (DES).

To demonstrate the incremental utility of SSF for individuals undergoing CCTA, with expected improvements in image quality and diagnostic accuracy.
