Active clinical trials for "Arteriosclerosis"

To assess changes in coronary calcium measured by electron beam computed tomography (EBCT) as a predictor of coronary heart disease (CHD) events.

Our study aims to explore the value of new imaging technique package in predicting early neurological deterioration (END) as well as 90-day unfavorable outcome in patients with acute ischaemic stroke.

Diabetic type 2 patients (DB2) has a higher prevalence of coronary artery disease (CAD) than non-diabetic persons. Presence of CAD results in murmurs arising from the filling of the arteries and can be detected by the CADScor System and can together with biological patient profile indicate the risk of presence of CAD in the patient. In the pilot study 100 asymptomatic DB2-patients examined with CADScor System and biomarkers will be compared with computed tomography (CT) cardiography and single-photon emission computed tomography (SPECT) for assessing if combination of patient profile (gender, age etc) combined with above measures may give rise to new improved risk scoring method for he DB2-patient.

Viability assessment remains a clinical challenge in patient with coronary artery disease and left ventricular dysfunction. Several imaging modalities are available for evaluating myocardial viability, based either on perfusion or on contractile reserve analysis. Briefly, perfusion analysis is highly sensitive and contractile reserve highly specific. A combined analysis of both perfusion and contractile reserve has been proposed to improve the diagnostic accuracy in patient referred for a revascularization procedure. However, the value of this combined analysis has not been validated in unselected patients referred for viability assessment. The patients enrolled in the study will undergo a nitrate enhanced rest gated SPECT using a Tc-99m labeled tracer (sestamibi or tetrofosmine) followed by a second gated SPECT acquired during a low-dose dobutamine infusion (10 mcg/kg/mn). All patients will have a 6-month clinical and imaging follow-up, including physical examination and a nitrate enhanced rest gated SPECT using the same radiopharmaceutical. All treatments received during this 6-month period will be recorded, including medical therapy and coronary revascularization (angioplasty, stenting and CABG). Finally, the value of baseline perfusion and contractile reserve analysis in predicting left ventricular ejection fraction changes at 6-month follow-up will be evaluated.

To determine the factors associated with progression of sub-clinical atherosclerosis and to evaluate the associations between the progression of sub-clinical atherosclerosis and the development of clinically manifest atherosclerosis.

The purpose of this study is to answer, among others, the following questions: 1) What are the outcomes when using the radial artery as a bypass graft in coronary artery bypass surgery (CABG)? 2) Can multidetector computed tomography (CT) be used to reliably evaluate coronary artery bypass graft patency?

To conduct a multicenter prevalence survey for characterizing pathologically the extent of atherosclerosis in the aortas and coronary arteries of young persons dying from accidental causes, suicide, or homicide.

Prasugrel and ticagrelor were both associated with a significant reduction in the risk of MACE in patients undergoing PCI for an ACS, mostly through a reduced stent thrombosis. The 1-year relative risk reduction (RRR) of definite of probable stent thrombosis in patients receiving a DES were fairly different in TRITON-TIMI 38 and PLATO trials. The incidence of "biologically active" stent (DES or BVS) thrombosis is largely variable according to different lesion settings. We aim to verify the translation of the postulated different reduction in thrombosis rate among various P2Y12 inhibitors (clopidogrel, prasugrel and ticagrelor) in a high-risk setting such as the PCI with DES or BVS in CTO and bifurcating lesions.

This study investigates whether chronic heart rate reduction with ivabradine (Procoralan®, Servier, France) affects aortic compliance and endothelial function in patients with chronic stable coronary artery disease.

To determine whether there were differences in the prevalence and extent of atherosclerotic lesions in the coronaries and aortas between Alaskan natives and non-natives, and whether the extent of the lesions was related to omega-3 fatty acids in blood and tissues.
